| Title: Crested Tunnel Barriers for Fast, High Density, Nonvolatile Memory Devices | |
| Abstract: Crested multi-layer tunnel barriers have been proposed, which offer a revolutionary solution to overcome density to speed trade-offs characteristic of present data storage technologies. Practical implementation of the proposed technology will involve use of thin film materials which are readily manufacturable and CMOS-compatible. A critical need exists for experimental verification of the theoretical predictions regarding these advanced structures. In addition, challenges lay ahead in developing a suitable deposition technology for fabrication of the ultra-thin graded or multilayered structures involved. Advanced Fuel Research, Inc., and the State University of New York at Stony Brook will develop a technology for fabrication of crested tunnel barrier devices based on promising thin film material combinations. Phase I will demonstrate barrier tunneling in asymmetric, two-layer barrier structures in good agreement with theoretical predictions. Phase I will also conduct a study to assess critical manufacturing issues such as suitable deposition methods required for fabrication of the ultrathin layer crested barrier devices in a production environment. Phase II will support continued theoretical development, develop scalable deposition processes, and demonstrate prototype memory devices.Successful development of the proposed high density, fast memory technology will have immediate impact in portable electronic components that require low cost, minimal power consumption, nonvolatile memory, i.e. flash memory. As the demand for increased memory and functionality continues, faster, higher density flash memory technology will be required. It is expected that a fast, high density, low power, nonvolatile memory technology will also compete with DRAM technology presently used in personal computers. The commercial potential is enormous, with both flash memory and DRAM representing multi-billion dollar per year markets. | |

| Title: Development of Textured and Single Crystal Garnet Fibers for Advanced Oxide CMCs | |
| Abstract: The proposed research effort focuses on developing a method to synthesize and crystallize doped YAG to produce textured or single crystal fibers that exhibit little degredation in strength and excellent creep resistance at temperatures in excess of 1400C. YAG will be synthesized from polymerized sol gel precursors, drawn into fibers and continuously crystallized using a quadrapole crystallizer. This approach is continuous, and fully scaleable. The effect of cationic dopants on the recrystallization of YAG will be investigated by electron microscopy. Measurment of the individual tensile strengths and creep resistance of the fibers at temperatures up to 1400C will be performed. Microstructures and mechanical property information that is obtained will be used to influence the processing conditions that are selected. The results will establish further understanding of the structure-process relationship for the fabrication of stable, creep resistant oxide fibers for a broad range of applications.It is expected that the proposed research will lead to the development of a stable high temperature oxide fiber with little loss in strength and exceptional creep resistance at temperatures in excess of 1400C. When scaled to commercial size and quantities, these fibers will be used extensively for oxide preforms for a range of CMC engine components - combustors, turbines, commpressors, exhaust nozzles, vanes, blades and shrouds etc.. Additionally, if single crystals can be produced, extensive opportunities exist for fiber optic applications. | |

| Title: Corrosion Suppression novel inhibitor modified silane systems. | |
| Abstract: Phase I feasibility research will be based on developing novel organic/inorganic hybrid, inhibitor modified or reacted silane based corrosion inhibitor systems that will enhance corrosion suppression capability of existing organic/inorganic hybrid corrosion inhibition systems by incorporating novel inhibitor modified silanes such as novel silanes modified with imidizoles as a novel corrosion inhibitor, or BTSE, BTSPA, BTSPS or di or tri epoxy,amino, methacrylo or amino sialnes modified or reacted with novel inhibitors in triazole family to enhance corrosion suppresion in physically occluded regions of aircraft exposed to wide range of environments. Chemical properties will include self healing capability to suppress corrosion in cracks and defects and scratches of surface of aircraft, and specially to suppress the propagation of cracks and defects.The designer corrossion suppressor phase I research is to develop corrosion suppression systems that will result in multimillion dollars cost reduction as a result of non surface pretreatment and non chromated nature of the technology which is also enhanced with novel inhibitor modified silane based corrossion supressor chemistry. Anticipated benefits include self healing properties, suppression of corrosion in physically occluded areas because of ease of application and superior wettabilty and coatability , and suppression of crack and defect propagation. Benefits include commercial applications in aerospace, construciton, chemical and petrochemcial, automtive, electronics,sporting good, and aircraft industries. | |

| Title: Closed-Loop Control of Separation in Subsonic and Transonic Flows | |
| Abstract: Clear Science Corp. and Syracuse University propose to design and demonstrate a closed-loop system for controlling flow separation on lifting surfaces over the transonic flight regime---offering the potential of significantly higher mission effectiveness in weapons like LOCAAS. Reduced-order models of the flow are required for control in real time, and these models must reflect the critical dynamics. Output to the feedback system must be physically measurable in realistic applications. Minimizing the power requirements of an active flow control system means exploiting physical mechanisms that amplify the effects of small-scale input. Through open-loop experiments and simulations conducted by our team, we have demonstrated technology that utilizes wall-mounted sensors and pulsed jets to produce large-scale effects with small-scale input. In Phase I, we will integrate our proven technologies into candidate closed-loop control systems. We will evaluate controllers that combine low-dimensional models, optimal design, and feedback control. We will evaluate sensor, actuator, and signal processor hardware based on performance, size, weight, cost, and power requirements. Controller evaluation will be based on robustness over a range of conditions and adaptability to sensor noise, data latency, and model uncertainties. We will downselect components and a controller design for Phase II hardware-in-the-loop demonstrations at subsonic and transonic conditions.Increased performance requirements and tighter constraints on volume and weight force airframes closer to their design limits. Jet engine manufacturers must reduce surge margins for the same reasons. Airframe and propulsion system designers need new tools for these new challenges and all stand to gain from an experimentally validated computational environment for designing systems for closed-loop control of flow separation. | |

| Title: Corrosion Prevention Coatings | |
| Abstract: Military aircraft are largely constructed from special aluminum alloys, which typically have secondary precipitate phases that substantially improve mechanical strength. However, these regions also promote corrosion in such common environmental conditions as acid rain, saltwater, and thermal cycling. The problem is significant enough that the U.S. Air Force expends approximately $1 billion per year on corrosion-related maintenance for its aluminum-skinned aircraft. The team of CMS Technetronics and two research groups from Oklahoma State University proposes to develop next-generation, nanoengineered surface treatments that will meet the goals of superior protection against corrosion, environmental compliance, and controllable removal. The team's advanced, integrated, composite-nanophasic materials systems can provide the USAF with corrosion-inhibiting properties superior to present coatings systems.The development of advanced corrosion suppression methods utilizing nanoengineered structures offers new opportunities for aircraft corrosion prevention and maintenance. Use of "release on command" capabilities combined with "smart" corrosion inhibitors will increase the efficacy of the newly developed environmentally compliant surface treatments. Industries benefiting from this technology include the commercial aerospace industry and other industries utilizing aluminum alloys. | |

| Title: Hearing Protection System for Extreme Noise Environments | |
| Abstract: Creare and Dartmouth College propose to design, fabricate, and test a safe and effective system for hearing protection in very high noise level environments. Current Air Force ground crews are forced to work in close proximity to aircraft engines that produce in excess of 150 dB of noise, which can result in noise-induced hearing loss after brief exposures without sufficient hearing protection. The harmful effects of noise at such extreme levels is manifest through both air- and bone-conducted noise. These flight and ground crews also have a need to communicate with other personnel. However, no existing hearing protection system offers the right level of noise reduction for these crews to work safely in extreme noise environments. Our extreme noise reduction system is based on combined passive and active noise reduction technologies and will mitigate the contribution of both air- and bone-conducted noise on the inner ear. During the Phase I project, we will use an innovative technique to quantify the contribution of air- and bone-conducted noise to the inner ear and develop an extreme noise reduction system based on the data. During the Phase II project, we will fabricate and test a prototype extreme noise reduction system. The Creare extreme noise reduction (ENR) system will reduce the harmful effects of long duration exposure to extremely high noise levels and will facilitate speech intelligibility. The ENR system will be used by tank crews, flight crews, flight deck personnel, mechanized infantry, and commercial operators of noisy equipment. | |

| Title: High Stiffness Passive Damping Concepts Using Materials or Innovative Mechanisms | |
| Abstract: This effort will investigate a recent breakthrough in damping materials developed under AFOSR sponsorship at UCLA for potential application to launch vehicle and spacecraft component vibration mitigation. CSA believes that the proposed effort is unique in that it offers, for the first time, a practical high performance passive solution to the vibration suppression needs of several Air Force applications. More specifically, this effort concentrates on improved launch environment mitigation methods for sensitive payloads such as those envisioned for surveillance and directed energy applications. The focus of the investigation will be on a new magnetostrictive particulate composite (MPC) material, which exhibits high amounts of damping via stress-induced domain wall motion of a magentostricive particulate cured under magnetic field in a host matrix material. Initial data suggests that the material has tremendous promise as a lightweight, high-stiffness, high-damping multifunctional material. This effort will examine, optimize, and test the material in the context of the launch environment application.Goal of the research is to develop and demonstrate a multifunctional composite material that has both high stiffness and high damping. Commercial applications for such a material range from high performance lightweight aerospace structures to automotive, sporting goods, and other industrial applications. | |

| Title: Advanced Hearing Protection | |
| Abstract: Some ground crews for aircrafts are exposed to ambient noise levels up to 150 dB SPL: at these levels, conduction of sound through tissues is significant and may be responsible for hearing loss. Protecting the ear canal with earplugs and earmuffs cannot prevent damage caused by tissue-conducted sound. Our research partners at University of Illinois at Urbana-Champaign, experts in bioacoustics and audiology, will use finite element analysis to investigate the reception and conduction of sound through hard and soft tissues of the head and torso. From their work we will determine the attenuation characteristics that protective gear should possess. We will demonstrate methods to increase the attenuation provided by passive earmuffs. Similar improvements can be made to helmets and garments, but these will await completion of the tissue conduction analysis. Finally, we will begin to assess the feasibility of incorporating active cancellation of air-borne noise into headgear other than earmuffs; effective actively controlled earmuffs already exist on the market.The technology developed to protect the hearing from high-intensity sound can have numerous military and consumer applications. Potential military devices include 1) hearing-protection for aircraft ground crew, and for maintenance, repair, and testing personnel of aircraft engines, 2) helmets for ear and brain protection of pilots in military aircraft, and 3) ear protective device for crews in the engine room of a ship. Potential commercial devices include 1) hearing protection for patients and operating room personnel during extracororeal shock wave lithotripsy, 2) protective helmet for patients undergoing functional magnetic resonance imaging, and 3) ear protection devices for people in various industries using tools that produce high sound pressure. | |

| Title: Organic Solar Cells Using Star Conductive Polymers | |
| Abstract: A new class of organic photovoltaics is proposed based on star conducting polymers. These materials will provide superior hole and/or electron transfer properties that determine the ultimate efficiency of the devices. The star polymer architecture employs linear conjugated arms radiating from a centrosymmetric core, and therfore, unlike the linear arms alone, facilitate carrier transport in three dimensions. The materials have also been demonstrated to have improved processibility and adhesion. Phase I will seek to demonstrate the first photovoltaic cells using these materials based on incorporating soluble donor and acceptor polymers developed at the University of Florida to the star architecture developed at EIC, with a target Phase I solar conversion efficienty of 2-4%.Polymer solar cells are extremely lightweight, with a projected ratio of >600W/kg (10%, AM1) and potentially very inexpensive (<$0.5/peak watt). Military applications include very lightweight space payloads and portable power for ground-based operations. Commercially, they would make a great impact in the ~$1 billion photovoltaic market. | |

| Title: Machine Learning for Record Linkage | |
| Abstract: Machine learning offers an automated approach for deriving and maintaining the mappings necessary to link records across databases. The approach we propose here, if successful, will significantly advance this technology. Previous work in this area has largely ignored the fact that each source typically has uniform conventions for representing data. By taking this into account, we can to a better job of understanding and characterizing the relationships between different sources. Specifically, it is possible to analyze and/or deconstruct individual fields and thereby derive transformation rules for mapping between records in different databases.Record linkage is fundamental issue for applications that involve integrating multiple information sources. The problem is becoming more acute in large organizations, including the Air Force and other military branches, as they strive to tie together diverse, heterogeneous information systems. Typically different data sources employ different terminology (codes, names, identifiers, etc) when referring to the same entities (equipment, locales, people, organizations, etc.), and creating and maintaining these mappings is difficult. The machines learning approach we propose will automate the processes of deriving and maintaining the mappings necessary to link records across databases, minimizing the amount of human effort required. | |

| Title: High-Damping Composite Materials for Advanced Aerospace Structures | |
| Abstract: The innovation addressed in this proposal is an advanced composite material that provides a high degree of damping with little sacrifice of stiffness or strength. By integrating the functions of load-bearing and vibration suppression, this high-damping composite material (HDCM) will enable the elimination of parasitic structural components. This simplification will improve the reliability of structures and control systems, while allowing significant cost savings through the reduction of design time and weight. When applied to launch vehicles and advanced space structures, HDCM will help reduce the cost-per-pound to orbit, fulfilling a mission-critical need for the Air Force. The proposed research and development plan will leverage Foster-Miller's state-of-the-art composite fabrication techniques with the advanced modeling and structural vibration experience of the University of Colorado, Boulder, to meet the Air Force's requirements. To reach this goal, several critical milestones must be reached. These include the primary objectives of this proposal: achieving proof-of-concept of the HDCM, and demonstrating flight-traceable fabrication techniques. Further product development milestones include showing enhanced performance of a typical aerospace structure, demonstrating said structure in a representative environment, and eventually flight-testing an engineering model before proceeding to full-scale production and flight-proving. (P-01510) Although the composite material that is the subject of this proposal is tailored toward spacecraft and launch vehicle applications, there is an even larger potential market in the non-space related government and commercial sectors. HDCM could see application in transportation (aircraft, watercraft, ground vehicles), construction (buildings, bridges, roadways, bunkers, storage tanks), heavy equipment (cranes, tractors, generators), and sporting gear (rackets, bats, golf clubs). Foster-Miller has had considerable experience with transitioning technologies in all of these sectors, and is well positioned to exploit this expertise. | |

| Title: Biomimetic Inspired Fibers, Materials, and Properties | |
| Abstract: The complex biological processing and spinning operations used by the silkworm and spider to create silk fibers lead to a morphology that yields exceptionally high combinations of strength, stiffness, and extensibility. In this proposed STTR effort, Foster-Miller will join with Professor David Kaplan and the Biotechnology Center at Tufts University in an effort to produce films from silk that possess unique and tailorable properties for emerging Air Force applications. Professor Kaplan has a world-class reputation in this area and is an acknowledged expert in the biology and characterization of silk. He will provide the team with technical expertise, laboratory characterization and material for this effort. Foster-Miller has extensive experience in lyotropic liquid crystalline polymer processing, the synthetic analog to the biological liquid crystal processing characteristic of natural silks. We will combine this expertise with our knowledge of polymer/solvent interactions to mimic the biomacromolecular assembly of spider silk. In this effort, films will be formed and oriented using a variety of processing techniques to demonstrate proof of concept. The methods developed and lessons learned on this effort can then be adapted and applied to the processing of high performance fibers in a subsequent Phase II effort. (P-01524) This program pursues broad materials technology development toward general implementation rather than an application-specific development. It is initially envisioned that bulletproof vests and parachute cords present military applications with good near- term pull. Ultimately, the material is likely well suited for highly optimized large space structures such as solar sails or space telescopes, applications where Foster-Miller is currently working on large deployable structures for the Air Force and NASA. In the commercial marketplace, preliminary target applications certainly include bulletproof vests as well as high strength cords and straps, prosthetic devices, and highly abrasion resistant textiles. | |

| Title: Flight Demonstration of Stealthy Closed-Loop Attitude Control | |
| Abstract: Flight demonstration of modern stealthy aircraft with an active flow control system is an important, complex, and challenging opportunity. The probability of success is maximized by a progressive plan in which complexity is introduced gradually. We propose a plan that includes flight testing of a simple system in Phase I and progressing to a multi-axis demonstration in Phase II. The proposed program develops a closed-loop attitude control system for an air vehicle, implementing and integrating active flow control actuators and sensors. Control system design will be based on robust, nonlinear sliding mode methods that account for air vehicle mechanics, large rotation kinematics and reduced-order modeling of the active flow actuators. Actuator technology focuses on stealthy approaches, such as synthetic jets, which eliminate the need for conventional hinged control surfaces. In Phase I, closed-loop roll control employing active flow actuators in the wing tip regions will be developed. Phase I culminates in flight testing using a modified radio-controlled aerobatic model plane (approximately 9 ft. wingspan and 135 mph flight speed). In Phase II, the investigation will be extended to multi-axis control over a wider flight envelope, for a jet-powered radio-controlled model with a planform representative of modern stealthy aircraft. The successful completion of this program will provide a substantial advance in the capabilities of stealth aircraft. | |

| Abstract: This contract develops and expands on the technology for micromachining silicon deformable mirrors as a result of work in Stanford research laboratories over the last 5 years. The commerical and military applications of this technology will be exploited and specific uses will be investigated. Hardware specific to applications will be prepared and evaluated for a few selected uses.The optics industry has many applications for compact and inexpensive wavefront correctors. There are many civilian and military uses for propagating laser beams or imaging through turbulent atmospheres. One specific application is to correct beams used in free space communication systems. Using an adaptive optic in any optical system can correct for thermally varying conditions, and allows the system designer to use less expensive optical elements. | |

| Title: Development of Advanced Crystalline Garnet Materials and Fibers | |
| Abstract: The fabrication of novel yttrium aluminum garnet (YAG) powders and their continuous polycrystalline fibers is proposed. These fibers will not only withstand oxidizing conditions but also offer excellent themomechanical properties including high strength, creep resistance, and damage tolerance above 1350 øC. The powders will be produced by a sol-gel process, and the Y and Al cations will be substituted with three different cations to decrease the lattice diffusion and subsequently the creep rate at high temperatures. The fibers will be formed via Viscose Suspension Spinning Process (VSSP), which is the most economical and versatile fiber processing technique. Our approach will resolve several technical shortcomings associated with the application of oxide fibers in CMCs due to their excessive creep at high temperatures.Creep resistant polycrystalline YAG fibers offer significant benefits for ceramic matrix composites used in oxidizing conditions and high temperatures. If successful, LMI and ACI are prepared to form a joint venture and also to license the technology to all interested CMC system companies. | |

| Title: High Temperature, High Bandwidth Fiber Optic Pressure Sensor for Gas Turbine Applications | |
| Abstract: Acquiring transient point measurements of pressure in gas turbine environments is very difficult using currently available sensor technology. The current state-of-the-art often requires researchers to sacrifice frequency response for increased accuracy, forcing them to make assumptions about the transient nature of the environment being monitored. Clearly, there is a need for flush-mounted sensor capable of acquiring transient measurements in high-temperature, gas turbine environments at discrete points for many current and proposed control schemes. Luna Innovations proposes to develop a fiber optic pressure sensor capable of acquiring transient point measurements in high temperature, propulsive environments. The operating principle of the probe will be based on proven extrinsic Fabry-Perot interferometric (EFPI) techniques. Luna will use its extensive experience developing and commercializing fiber optic sensors technology, including the previous development of less advanced fiber optic versions of such sensors, to design, develop, and construct the proposed advanced pressure measuring system for combustion environments. The data obtained by these sensors will be invaluable monitoring and control feedback throughout a gas turbine engine. This instrumentation is crucial to the development and operation of affordable and efficient 21st century gas turbine engines.Research in the high temperature instrumentation area will provide transducers with commercial uses that will include 1) aerospace, 2) high temperature monitoring in power generation facilities, 3) high temperature industrial process monitoring, and 4) automotive sensing for engine health monitoring and control. | |

| Title: Thin Film Flexible Photovoltaic Devices for Space Applications | |
| Abstract: In this STTR Phase I project we will employ a new technique applicable to the fabrication of flexible thin film photovoltaic devices for space applications. This technique is based on the ionically self-assembled monolayer (ISAM) methods of creating multifunctional thin-films monolayer by monolayer. These methods have been proven to yield self-assembled, electronically and photonically-active polymeric thin films. Luna Innovations demonstrated that the ISAM technique could be used to fabricate polymer light emitting diodes and electrochromic films. Photovoltaic devices are another important area of opportunity for conducting polymers used in combination with various electron acceptor materials. The precise spatial positioning of the electron acceptor and polymer layers using ISAM fabrication provides enhanced charge separation and photovoltaic response by orders of magnitude, comparable to that of silicon photodiode. ISAM polymer photovoltaic thin-films offer additional major advantages of excellent homogeneity, high mechanical, thermal and chemical stability, and low-cost. The films can be conformally fabricated over large areas on flexible substrates. The development of ISAM photovoltaic devices can result in high-efficiency and lightweight polymer solar cells. One could produce 10,000 m2 of active solar panels with a film thickness of the organic active layer of 100 nm using only 1 kg of organic material.ISAM polymer solar cells have immediate application in various commercial areas for inexpensive, lightweight, large area, flexible energy conversion devices in building structures, optical communications, consumer products, commercial electronics, as well as space applications. | |

| Title: Tunable Ionic Self-Assembled Monolayers (ISAM) for Corrosion Prevention Coatings | |
| Abstract: Corrosion of metal structures is estimated to cost many billions of dollars annually. The most common methods of corrosion inhibition or prevention involve the application of primers, paints and/or conversion coatings. The application and removal of these coatings require strictly controlled and regulated processes due to the toxicity and possible carcinogenic properties of the materials involved. A need exist to develop an alternative process for the application and removal of corrosion prevention coatings on large surfaces. LUNA Innovations has demonstrated a new coating process based on ionic self-assembled monolayers (ISAMS) and nanoparticles that 1) has demonstrated corrosion inhibition on 2024-T3 aluminum alloy, 2) neither contains nor generates hazardous materials, 3) offers the potential for "release on command" capabilities, and 4) has demonstrated practical application methods including spraying and non-electrolytic brushing. In this Phase I effort LUNA Innovations will investigate the "release on command" potential of ISAM coatings using electrical current, radiation, and chemical means. Furthermore, non-chromate inhibitors in the form of nanoparticles imbedded in the ISAM layer will be investigated. ISAM corrosion inhibition properties will be expanded to include 6061 and 7075 aluminum alloys.There are three major drivers that make ISAM corrosion prevention coatings a viable commercial product. First, ISAM coatings have lower material, operating and capital cost than comparable chromate conversion coatings. In addition to regulatory compliance, the environmentally friendly aspects of ISAMS result in additional cost savings. Low cost can make ISAM technology applicable to the automotive industry. Second, tunable or release on command ISAM coatings allow the simple application of mission coats for military applications. Release on command would also simplify maintenance and repairs when paint removal is required. Finally, the ability to coat large areas using spray technology would allow coating application to naval and maritime structures. | |

| Title: Novel Method for Cost-Effective Manufacturing of Single Crystal YAG Fibers from Nanosize Particles | |
| Abstract: Yttrium-aluminum garnet (YAG) single crystal fibers, 50 micron in diameter, of 100% Y3Al5O12 (YAG) composition, having either [111] or [001] orientations along the axis the fibers, will be fabricated utilizing a novel, versatile approach based on the Templated Grain Growth of Seeded Nanoparticles (TGGSN) method. Nanocrystalline powders of YAG will be synthesized and dispersed in organic binders and seeded with small elongated single crystals of YAG of [111] or [001] orientations, 10 to 20 microns in smallest dimension and an aspect ratio of 50 to 100 (1 to 2 mm). Continuous fibers will be spun from the seeded suspensions to produce ~50%-dense nanoparticle fibers containing the elongated single crystals oriented along the fiber axis. The pre-cursor fibers will undergo a series of heat treating steps to remove the binder, sinter the nanosize particles into a fully-dense nanograin material, and then, by using unique sintering facilities at the University of Illinois, induce the Templated Grain Growth process, during which the large oriented single crystals will grow along the axis of the fibers by consuming the nanosize particles.The resulting single crystal YAG fibers are expected to be a major step in the development of YAG fiber-based composites, because their small diameter should make them amenable to weaving, which is currently impossible with commercially-available YAG fibers of >100 micron diameter. In addition, the TGGSN approach is inherently very economical, as opposed to the prohibitively expensive Edge-Defined Growth method that is the only currently available method for manufacturing YAG fibers. | |

| Title: Evaluation of High-Frequency Electromagnetic Scattering via High-Order Multiple-Scattering Integral Asymptotics | |
| Abstract: The present text proposes development of a new approach for the numerical evaluation of high-frequency electromagnetic scattering for structures of interest to DoD. This approach, which relies on high-order high-frequency integral asymptotics, is entirely rigorous: it should account fully for all scatterer complexities and all electromagnetic effects - including multiple-scattering, diffraction, caustics, creeping waves, shadowing, penumbrae, etc. The high-order integral methods mentioned above were introduced recently by this PI and collaborators as a component of a rough-surface multi-scale solver. The goal of the work proposed here is to determine the merit of high-order asymptotic methods for evaluation of scattering from complex bounded scatterers, including air and land vehicles. Unlike rough surfaces, bounded scatterers: a) give rise to multiple scattering effects which cannot be accounted for by previous analytic continuation methods, b) they require complex geometric descriptions, and c) they necessarily give rise to complex shadowing processes. We expect the proposed work will result in technologies allowing for accurate evaluation of high-frequency bounded-body scattering within the proposed high-order asymptotic framework. The successful completion of this project will lead to significant improvements in the description of high-frequency scattering processes: an area of great importance for both national security and commercial concerns.As indicated in the AF01T009 topical description, the electromagnetic scattering attributes of actual-size inventory usually needs to be obtained by high frequency approximations - the previous versions of which suffer from various shortcomings. The proposed algorithms avoid all such shortcomings, which arise mainly from use of ray tracing or neglect of multiple-scattering and diffraction effects, by introducing a paradigm which accounts fully for multiple scattering and shadow boundaries, and which does not rely on ray tracing in any way. The military and commercial applications of such algorithms are very numerous indeed: they range from remote sensing of vehicles to mapping, antenna design, altimetry and communications. Thus, the successful completion of the proposed work will lead to significant benefits in a wide variety of areas, with a very substantial potential for commercial impact. | |

| Title: Reactants and Combustion Processes for Neutralization of Chemical and Biological Agents | |
| Abstract: The neutralization and destruction of chemical and biological agents requires unique approaches because of the hazards associated with dispersing materials that may not have been completely neutralized. The METSS Team is proposing to use formulations, similar to incendiary devices with spreading characteristics like NAPALM, that contain energetic materials combinations including specialty polymers/oligomers. At normal temperatures such formulations will be inert, but at elevated temperatures the energetic materials can be activated to release very active species. The latter, combined with the byproducts of combustion, will provide the necessary conditions for destroying chemical and biological agents. Mathematical models will be used to predict the nature and outcome of the combustion products and the possible reaction products. These results, in turn, will be used in an iterative manner to direct the formulation efforts for this concept.The formulations developed will be stable during production, transportation, and storage. When thermally activated, they will produce a highly reactive, dispersed combustion zone that should find use in battlefield conditions where chemical and/or biological agents have been deployed and residence times for neutralization reactions may be short. In addition, these novel formulations should be useful for non-military situations where chemical and/or biological agents are released, such as in terrorist atacks or cult demonstrations. They should be especially effective in contained areas. | |

| Title: Development of High Frequency Methods for Electromagnetic Scattering Problems based on Asymptotic Integral Equation Formulation | |
| Abstract: Our objective is to construct a new solution procedure for high frequency electromagnetic scattering and propagation problems, and to initiate building and validation of a new 3D high frequency Maxwell equations solver. The proposed method will constitute an extension of a recent asymptotic formulation of the electromagnetic integral equations for high frequency scatttering and radiation problem. The method will utilize a recursive procedure for solving Maxwell's equations in the integral form based on two elements: (a) analytical representation of the solution Ansatz including single and multiple scattering effects,creeping wave contributions, and diffraction on surfaces with edges and corners, b) suitable parameterization of the leading zero-th order component of the Ansatz in a differentiable form. Feasibility and computational efficiency of two different procedures for constructing the zero-th order Ansatz will be investigated. The first procedure will construct the zero-th order Ansatz for the full object by using ray tracing and wavefront propagation techniques. The other, domain decomposition based procedure, will be based on multiple scattering theory. The results will be implemented and tested a research version of the code which we intend to fully develop in the second phase.Significant improvement in the accuracy, domain of applicability and speed of the existing high frequency solvers which are of interest to DoD and in commercial applications. Ability to treat a wider range of problems of interset to DoD and in commercial applications, such as electromagnetic interference problems for aircraft antennas. | |

| Title: Design and Synthesis of Nanostructured Corrosion Resistance Coating for Ageing Aircraft | |
| Abstract: This STTR program would investigate the feasibility of ionic self-assembled monolayer (ISAM) synthesis techniques for the fabrication of flexible multilayer, multifunctional corrosion mitigating coatings for the protection of large area aluminum aircraft structural components. NanoSonic and our Virginia Tech STTR partner have already demonstrated that multiple properties and morphologies may be incorporated into such coatings by varying constituent nanoclusters and polymers through the thickness. Here, this would allow the combination of multiple desirable capabilities, including significant reduction in ion transport to the aluminum surface, an abrasion-resistant and water displacing topcoat, and controlled release-on-demand to permit periodic coating removal and recoating. This would build directly on related prior and current NanoSonic developments, including efforts involving the integration of multiple functionalities into nanocomposite ISAM coatings, and the conformal ISAM coating of large aircraft components. The PI and research team have directly related industrial experience in adhesive and coating development and upscaling. NanoSonic has exclusively licensed fundamental ISAM patents from Virginia Tech to enable protected technology transfer and commercialization. During Phase II, NanoSonic would work with a major U.S. aerospace contractor to demonstrate coating on large aircraft structures, and allow the direct transfer of the technology to established aircraft manufacturers and maintenance organizations.Effective molecularly self-assembled corrosion preventative coatings formed without environmentally unacceptable chromium-based inhibitors would have significant industrial use on military and commercial aircraft, marine structures, land-based vehicles, civilian infrastructure and consumer products. | |

| Title: Development of Synthesis and Large Scale Production Technology for Ultrahigh Energy and Density Fluoro-Organic Compounds | |
| Abstract: This STTR is to address the technical feasibility and commercial aspects of producing high-density fluorine-rich compounds that are significantly more reactive and energetic than conventional explosives to neutralize and destroy chemical and biological agents. The proposed project incorporates the outstanding scientific research base of the University of Florida Department of Chemistry with the technology marketing expertise of the New Era Technology, Inc. (NeTech) to conduct an R&D effort, which includes activities ranging from synthesis of innovative compounds to large volume production at a competitive cost. The effort will also overlap with and incorporate results of a basic science research effort that is conducted under a joint ISCT project (Title: Research on Combustion of Organophosphorous Esters: Burning Velocities and Flammability Limits) at the Institute of Physiological Active Compounds (Chernogolovka, Russia) and at the Institute of Chemical Physics (Moscow Region Russia.) The basic proposition is that strong SF5/NO2/NF2-substituted oxidizers should be able to be deployed in the battlefield to reduce the threat posed by biological and nerve agents. This research seeks to take advantage, in particular, of SF5-containing compounds that should be more reactive and energetic than conventional explosives. Goals for Phase I of this project include synthesis of model compounds, testing for efficacy in destruction of biological and nerve agents, and based on these results identification of appropriate final synthetic target materials. development of high energy explosives for the neutralization of chemical and biological agents; biological and nerve agent threat reduction; commercial development of high energy explosives | |

| Title: Self-Calibrating Dynamic Pressure Transducers for High-Temperature Instrumentation | |
| Abstract: Measurement of unsteady pressure at critical locations in gas turbine engines is highly desirable for validation of engine design, optimization of the operating envelope, and improvement of safety margins. Unfortunately, availability of sensors and instrumentation that can be reliably operated in the engine environments is rather limited. Prime Photonics, Inc. proposes to collaborate with the Virginia Tech Photonics Laboratory to develop and demonstrate high-temperature dynamic pressure transducers for instrumentation in gas turbine engines. The proposed sensors are based on the self-calibrated interferometric/intensity-based (SCIIB) sensor, a new sensor technology based on optical fibers, which for the first time successfully combines fiber interferometry and intensity-based devices into a single sensor system. The resulting sensor possesses all the major advantages of both interferometry and intensity sensors, including small size, high resolution, high frequency response, high temperature capability, ultra-low cross-sensitivity to temperature, and self-calibrating absolute measurement. For this program, sensors will be designed and demonstrated using both glass fibers for temperatures up to 800øC, and using single-crystal sapphire waveguides for temperatures up to 1500øC. An optoelectronic system to process the optical signals will be designed to achieve a bandwidth of 125 kHz. The small size will facilitate flush-mounting of the transducer.The proposed Phase I STTR program will demonstrate the feasibility of high-temperature high-bandwidth pressure transducers using optical methods in a self-calibrating configuration. Such high-temperature pressure sensors are highly desirable in the gas turbine engine industry for design validation and real-time diagnosis. These applications require measurement of pressure at many key locations, such as compressors, combustors, and turbines, there the temperatures are too high to permit the use of commercially available semiconductor presure sensors, which have a maximum operating temperature of 400 degrees C. Therefore, instumentation of gas turbine engines will form the initial target market for commercialization of the proposed technology. Additional markets in electrical power production, automotive engines, and glass and metal manufacturing will be evaluated and pursued if the market size will support commercialization. During the Phase II program, which will bring the technology demonstrated in Phase I to a level where commercial products are viable, Prime Photonics will seek outside investment in order to put in place the corporate infrastructure necessary for product manufacture and marketing. | |

| Title: Passive Structural Vibration Damping with Ferromagnetic Shape Memory Alloys | |
| Abstract: The proposed Phase I will explore the application of composites of polymer and ferromagnetic shape memory alloys (FSMAs) to passive structural vibration damping. The large hysteresis present in the stress-strain behavior of NiMnGa, a ferromagnetic shape memory alloy (FSMA), and other shape memory alloys (SMAs) suggests that both FSMAs and SMAs have the potential to dissipate mechanical energy more effectively than piezoelectrics, viscoelastic materials (VEMs) or Terfenol-D. However, FSMAs, unlike SMAs, allow harvesting a portion of the vibrational energy as usable electrical energy. Further, an external field can be applied to vary the stiffness of the FSMA composite. In principle, stress variations in the FSMA spanning more than ñ10 MPa can be coupled to twin boundary motion-induced deformations of several percent, representing a mechanical loss of order 1 MJ/m3 and a loss tangent in excess of 0.5. The Phase I will combine fabrication, test, and design tasks, in order to rapidly assess the merits and challenges of proceeding further: (1) fabrication of composite polymer-NiMnGa samples, (2) static and dynamic testing of the samples, and (3) design of practical concepts for applying FSMAs to a structure. We will fabricate and test samples of NiMnGa composite with various degrees of particle alignment, easy axis orientations, and fill factors with the intent of maximizing vibration damping. The program will conclude with identification of practical means for applying FSMAs to a representative truss structure during the Phase II and estimation of the resulting damping. Wind, earthquakes, accelerations and reciprocating and rotating machinery represent disturbances that can force undesired and potentially destructive oscillations in both ground- and space-based equipment: bridge trusses, towers, civil structures, buildings, industrial equipment, space station, launch vehicles, etc. Materials that more effectively damp vibration than existing polymer-based VEMs offer a promising means for attenuating these oscillations, reducing both design, construction and life-cycle costs for these structures. | |

| Title: Intelligent Record Linkage Techniques Based on Information Retrieval, Natural Language Processing, and Machine Learning | |
| Abstract: The sheer magnitude of information available online via the Internet has overwhelmed the ability of existing search tools to produce useful query responses. Current web-search techniques typically fail to correlate relevant documents that are identified in different ways, such as synonyms and acronyms. The challenge is to find an approach that can obtain highly accurate matches even when those documents do not share any obvious attributes with the query, and with minimal information requirement from the user. The objective of this STTR project is to develop an information management system to rapidly and accurately linking records of related information from web-based information sources. In Phase I we plan to identify, implement, and evaluate hybrid approaches for cross-record linkage, using a combination of machine learning, information retrieval, and natural language processing methodologies. This will involve the integration of pre-processed outputs of multiple approaches for record linkage into a significantly higher-quality result. In particular, we will investigate the use of selected statistical, Artificial Intelligence and Neural Networks techniques for improving the record linkage performance of information management systems. University of Maryland (Baltimore County) will be the research institute partner for this effort, under the direction of Professor Charles Nicholas, an internationally recognized expert in information retrieval and knowledge management. Commercial applications of the proposed technology include all private sector companies, federal and state agencies who need to acquire and manage large amount of information in the form of text documents in order to stay competitive or efficient. It will appeal to knowledge-intensive businesses, small/medium companies, individual consultants, universities and federal research institutes as a cost-effective alternative to traditional database or web search and match engines. | |

| Title: Modeling and Closed-Loop Control of Complex Flows Over Aerodynamic Surfaces | |
| Abstract: The use of active flow control can reduce or eliminate the number of aerodynamic control surfaces in aircraft. Elimination of control surfaces results in a reduction of weight and drag, as well as radar observability. Recent advances in Micro Electromechanical Systems (MEMS) technology have rendered it a feasible alternative for unsteady flow sensing and control. This project will be performed jointly by Scientific Systems Co. and Prof. Rediniotis from Texas A&M University, and will demonstrate the use of MEMS for closed-loop flow control. In particular, a delta wing is controlled by actively inducing or delaying Vortex Breakdown (VBD) so as to globally affect the flow over the wing in a desired way. The feedback mechanism is hingeless and consists of MEMS-based flow sensors and small Pneumatic Vortex Control (PVC) jet actuators. During this effort, we will develop modeling and control design algorithms for active flow control. Proposed Phase I tasks include: (a) acquisition of unsteady flow data, (b) control-oriented reduced order unsteady flow modeling using wavelets, indicial functions, and system identification techniques, (c) feedback controller design and numerical evaluation using robust control techniques, and (d) planning for real-time flow control demonstration in Phase II. Unsteady flow data will be acquired from the facilities in the fluid dynamics laboratory at Texas A&M University.Active control of vortical flow fields has applications in jet engines and turbomachinery, rotorcraft, air traffic control, and UAV formation flying. MEMS-based sensing and actuation technology has applications in NDE of structures, and bio-mimetics. | |

| Title: AlInGaN-based Crested Quantum Tunneling Barriers for Advanced Data Storage Systems | |
| Abstract: We propose a new way to reach a dramatic speed-up of floating gate memories by using quantum-mechanical tunneling through specially shaped ("crested") tunnel barriers. In contrast to the usual, uniform Fowler-Nordheim barriers used in existing floating gate memories, the maximum height of the crested barrier may be strongly suppressed with even moderate changes of applied electric field.Miniaturization of digital electronic circuits and systems is heavily dependent on increasing the density of semiconductor memories, with appropriate scaling down of their memory cells. Hardware for ultra-dense (more than 1 terabit/cm2), ultra-fast (less than 10 ns read-write time) memory storage is not currently available. The implementation of the crested barrier design is expected to yield barriers with tunneling transparency changing by 18 orders of magnitude under a change of applied voltage by a factor of 2 to 3. The read/write time is expected to reduce below 10 ns. | |

| Title: Machine Learning for Record Linkage | |
| Abstract: The World Wide Web of the future will contain significantly more information. It will be enabled to machine process the information stored allowing users to find information with less work. The adoption of standards like eXtensible Markup Language (XML) and the Resource Description Framework (RDF) on the WWW are significant steps to realize the vision of the concept of the "Semantic Web." World Wide Web Consortium standards such as XML and RDF are being used to create the "Semantic Web." DARPA is using XML on the DARPA Markup Language (DAML) project. XML, RDF, Machine Learning and Natural Language Processing will be combined to implement the Semantic Web. Software Solutions proposes to develop a standards-based system of software packages incorporating Machine Learning that will allow intelligent record linking and searching of the World Wide Web of the future for the most relevant information to the user. The underlying software technology will utilize XML and RDF standards and facilities. The user interface to the system will learn a particular user's human language concepts and associate these with similar concepts from the semantic web and databases, as well as learn from other human users in the same area of expertise. A machine record linkage system, generated rules and heuristics, linkage repository, and machine learning algorithms can be sold to government agencies, companies, universities and research institutes and search engine companies on a worldwide basis. | |

| Title: Experimental Active Separation Control on a Wing Section | |
| Abstract: Technology in Blacksburg (Techsburg) and the Vibration and Acoustics Laboratories (VAL) at Virginia Tech propose to investigate the potential of a combined suction and blowing system to provide active flow control on a 2D wing (airfoil). Techsburg has developed a novel method to produce suction and blowing from the same fluidic actuator that reduces complexity over separate systems and produces more mass flow for wake filling than traditional blowing. Feedback signals from an array of flush mounted microphones, which sense the separated flow region, will be fed to a system controller which will actuate valves for multiple suction and blowing holes on the wing surface. This will force re-attachment of the separated flow and restore the lifting properties of the wing. This flexibility makes the proposed system unique and opens up new possibilities for new aircraft control laws without flap actuators. The commercial opportunities also extend to enhanced performance of high lift systems on commercial and military aircraft.A successful and practical method for active flow control has a potentially large market in both military and commercial aviation. The civil aircraft industry may utilize flow control to enable the use of lighter high-lift systems which will reduce fuel costs. Military aircraft could also benefit from improved high-lift designs, but more improvements are likely for unmanned aircraft such as elimination of traditional control surfaces. | |

| Title: Flexible Photovoltaics Based on Organic Matrix Nano-Composites | |
| Abstract: Triton Systems, Inc. and Clemson University propose to develop a flexible polymeric photovoltaic assembly using a highly efficient innovative photovoltaic polymer coupled with flexible polymeric support and protective layers that can withstand the space environment. The Phase I program will verify recent data from Clemson showing that a new polymer combination has the capability to meet power generation to weight ratio of 200 W/kg at space-based illumination levels, together with a power efficiency of more than 10% at terrestrial illumination levels. To meet durability requirements for spacecraft applications, Triton will show in Phase I that it's novel polymer coatings and films can protect the photovoltaic layer from the environment, including atomic oxygen, ultraviolet radiation, and other space-based operational conditions. The Triton and Clemson teams will successfully complete the development work using direct experience in novel space-based flexible polymers and the photovoltaic materials. The flexible polymeric photovoltaic system will allow folding and compact storage, along with greatly reduced weight, not possible with current inorganic photovoltaic systems. Flexible polymeric photovoltaic systems will provide space and weight benefits, along with the attendant cost savings, to future power generation equipment for satellites and space missions. Flexible photovoltaic power systems will find many terrestrial applications including mobile field operations for military service, and domestic and recreational power supplies for commercial applications. | |

| Title: GaN-based Submillimeter Wave Quantum Emitter | |
| Abstract: WaveBand Corporation proposes to develop a new source of electromagnetic waves in the terahertz spectral range. The source is based on an electrically driven III-Nitride semiconductor superlattice designed to deliver high-power and high-frequency current oscillations. The fabrication technology employs a robust metal-organic vapor chemical deposition. The operating frequency is tunable by the driving voltage and can also be engineered by the geometry of the superlattice. The source is free from geometrical constraints that restrict the output power in resonant tunneling diodes. The source will find applications in target seekers, space communication systems, sensors, collision avoidance systems, and atmospheric sensing.The proposed terahertz source belongs to a new generation of solid state microwave sources based on nonlinear electric properties of biased semiconductor superlattices and will be applicable to missile smart munitions, wireless communications, ultra-high-speed integrated circuits, plasma diagnostics, remote sensing of toxic agents, radio astronomy and molecular spectroscopy, collision avoidance systems and surveillance radars. Active elements in the terahertz region will offer a bridge between microwave and optical frequencies in material systems, thus providing a broad range of applications in optical modulators and other optoelectronic devices and integrated circuits. | |

| Title: Intervalence Band THz Laser in p/p+ Ge Heterostructure | |
| Abstract: In this STTR phase I project, a new THz laser mechanism based on p/p+ periodically doped Ge heterostructures will be studied. The intent is to eliminate the optical phonon scattering required in traditional bulk p-Ge lasers, which causes overheating and limits their duty and gain. A CW laser with 1-4 THz tunability and picosecond pulse capability is anticipated. The new mechanism is based on selective scattering of light and heavy holes on the periodic p+ layers, leading to light-hole accumulation and amplification of THz emission on direct light- to heavy-hole transitions. The average hole concentration will be increased by several orders, giving a proportional increase in gain. A candidate structure will be selected from results of Monte Carlo simulations of hole dynamics in crossed electric and magnetic fields for various delta-, square-, and sinusoidally-modulated doping profiles. A contract manufacturer will grow the structure. The doping profile will be verified by the electron beam induced current technique, and far-infrared gain will be measured.

| Title: Phage Array Biosensor for Detection of Biowarfare Agents | |
| Abstract: Agave BioSystems, in collaboration with Professor George Malliaras of Cornell University, proposes to develop a unique and innovative biosensor based on induced luminescence of captured BW bacterial agents and organic light emitting diode (OLED) technology. The system would use an array of bacteriophage engineered to express fluorescent protein in infected BW agents. The specificity of the phage provides capture of only targets of interest, while the infection of the bacteria and natural replication of the expressed protein will provide the detection signal. Using novel OLED arrays, a phage array chip can be constructed similar to DNA chips for multianalyte detection. The combination of the phage array approach with OLED detection allows development of a powerful biosensing system that does not require additional labeling, sample manipulation, or sophisticated microfluidic and pumping mechanisms.Potential markets include the food processing, environmental, medical and agricultural sectors. Relevant examples include the detection of Listeria monocytogenes in dairy foods and detection of multi-drug resistant bacteria in hospitals and clinics. All bacteria responsible for these outbreaks are susceptible to phage infection, and thus are likely candidates for detection by the phage array biosensor. | |

| Title: An Electro-optic Near-field and Thermal Mapping System for Microwave and Millimeter-wave Circuits and Antennas | |
| Abstract: The objective of this Small Business Technology Transfer (STTR) project is to develop a prototype compact, portable electro-optic EM/thermal imaging system. The proposed electromagnetic/thermal imaging system can be directly utilized for the characterization of various RF structures including complex integrated circuits and large-scale antenna arrays. It provides near-field and thermal profiles of RF structures with an unprecedented high resolution and a measurement bandwidth over 100GHz. In the Phase I feasibility study, the capability of combined EM and thermal imaging will be demonstrated based on the existing electro-optic imaging system developed at the University of Michigan. A fiber-based laser will be integrated as an optical source into the system to make it compact and portable.The proposed electromagnetic/thermal imaging system can be utilized from the early design stage to the final performance validation of various FR structures for military and industry applications including large-scale high-density integrated circuits and active arrays. | |

| Title: Overexpression of Phosphotriesterase, a Metallo-Organophosphorous Hydrolase by a Novel and Versatile Protein Expression System | |
| Abstract: A unique recombinant protein overexpression system will be investigated for the production of phosphotriesterase, an organophosphate hydrolase from Pseudomonas diminuta MG and Flavobacterium sp. ATCC 27551. This enzyme is a leading bioremediation candidate for large-scale detoxification of insecticides and chemical warfare agents. The hydrolase will be prepared in three different versions using this novel system. A soluble form, a membrane-bound version and a fusion protein suitable for biosensor applications will be attempted. This versatile expression vehicle could be very effective for membrane protein applications, an important niche where systems currently available have been shown to be inadequate. Furthermore, the low-cost nature of this system is very attractive for large-scale protein production purposes.This system will occupy an important niche market where expression systems currently available commercially are not effective. This system can be used for the mass production of medicinally important membrane proteins and in structural genomics efforts of membrane proteins. The recombinant membrane proteins can be marketed for use in high-throughput screening, in structural biology efforts of medicinally important membrane proteins hence crucil in structure-based drug design endeavors. | |

| Title: Recombinant protein production in high cell density fermentation of R.eutropha using T7 polymerase system | |
| Abstract: Recombinant protein production in high cell density fermentation of R.eutropha using T7 polymerase system: Organophospho compounds are known to include several highly potent cholinesterase inhibitors. Such compounds can be readily obtained by conventional organic synthesis and their deployment can pose a serious threat to human life. Efforts to protect against the toxic effects of organophospho compounds have focused on enzymes that are able to hydrolyze the phosphoester bond and thereby substantially reduce their toxicity. The main obstacle in obtaining more than experimental quantities of this important chemical catalyst has been the unavailability of cost-effective enzyme expression system. GlycoFi is interested in developing genetic tools to overexpress proteins in high cell density fermentation. We propose to establish a T7 RNA polymerase based protein production system in a robust fermentation organism, Ralstonia eutropha. Our academic collaborators (Dr.Gerngross' lab at Dartmouth College) have been able to establish high cell densities of about 180g/L in R.eutropha under industrial feed conditions. T7 RNA polymerase system has been one of the most efficient recombinant protein production system developed. Although high yields (about 50% of total protein is recombinant protein) have been obtained in other bacteria (E.coli and Pseudomonas) in laboratory scales, various factors like proteolysis, inclusion body formation, difficult large scale fermentations have limited their production capabilities. In Phase I of the project, we would establish the T7 RNA polymerase system in R.eutropha and construct a plasmid to overexpress the gene of interest under the T7 promoter. Assuming that we are successful in achieving relative protein yields similar to other bacterial systems in R.eutropha, the high cell density fermentation capability of the organism with T7 expresssion system would enable us to produce recombinant protein titers of about 40-50 g/L. Successful completion of phase I is anticipated to demonstrate the superiority of the proposed bacterial expression system over existing methods of recombinant protein production. We would establish a low cost protein production system to produce high yields of Organophospho hydrolase, an enzyme used to reduce the toxicity of organophospho compounds (cholinesterase inhibitors). While we use OPH as a model enzyme, other applications that require large quantities of protein such as chemical/biological decontamination, bio-organic synthesis, materials for tissue engineering and molecular motors based on proteins, would greatly benefit from the new low cost protein production system. | |

| Title: Telemedicine and Advanced Medical Technology - Medical/Surgical, Mission Support Modeling, and Simulation | |
| Abstract: Immersion Medical and the Uniformed Services University of Health Science (USUHS), aims establish the feasibility of a medical training simulator for Central Venous Catheterization (CVC). The proposed project involves several technical advances. Tactile feedback user interface hardware designs will be researched to serve as a realistic proxy for catheters and other devices used during CVC. This interface device is anticipated to require force feedback in three axes: pitch, yaw and translation. Innovative "active" haptics (a.k.a. force feedback) will be developed as well as controlled passive force feedback to provide realistic procedural feel. Planned software advances include refinements in computer modeling for the deformation of surfaces and for the interaction of rigid catheters with body tissues that are pliant (e.g., blood vessels) and rigid (e.g., bone) body tissues. IN success, the completed CVC simulator will be operable on a high-end laptop for enhanced portability. It will be a real-time training device that integrates visual, haptic, and audio features to create an environment for performing central line placements. Evaluation for feasibility will be conducted at the USUHS. In success, the proposed project will improve patient outcomes and practitioner satisfaction, decrease medical costs, and will serve a broad market need. As a component of both Advanced Cardiac Life Support (ACLS) and Advanced Trauma Life Support (ATLS), CVC is a procedure for which advanced training has important implications in both military and civilian medicine. By creating a simulator for CVC, we can transcend problems with traditional training methods (human patients, animals). Training with a simulator has numerous advantages for the trainee, including: no risk to patients, no risk to trainees (e.g., no exposure to patient blood-borne pathogens), the opportunity to gain familiarity and comfort with the procedure through repetition, exposure to various cases with built-in complications and pathologies, and objective measurement of learning progress and procedural competence through longitudinal data tracking of trainee performance. The implementation of the proposed technology will enable the DoD to provide improved medical support to the wounded soldier through enhanced medical training with improved diagnosis, rehearsal, and treatment. In success, the proposed project will improve military readiness through shortened recovery times, and will lead to the production of commercially viable products with educational and training benefits for U.S. hospitals and medical schools. Laptop portability will further allow training in field situations currently inaccessible for CVC training. | |

| Title: Bioengineered Proteins for Chemical/Biological Defense, Protection, and Decontamination | |
| Abstract: The overall goal of Phase I is to generate preliminary sequence, functional, and pathway data for Pichia pastoris and to use that information to develop a strategy for strain improvement in Phase I This process will involve the construction of a highly random plasmid library and generation of 30,000 sequencing reactions. Assembly of the contigs will be done using the Phred-Phrap-Consted suite of assembly tools. We will then identify open reading frames (ORFs) using both public and proprietary gene searching programs. We expect to identify 80-85% of the ORFs in the genome at this level of coverage. The identified ORFs will then be subjected to a FASTA search against IG's proprietary IG's non-redundant database containing over 650,000 ORFs that represent 299 genomes currently. Functional assignments will then be made. Upon the identification of significant regions, strategies will be developed for strain improvements using gene disruption, gene replacement and heterologous gene expression. The budding yeast Pichia pastoris is widely used to produce foreign proteins for industrial, academic and military purposes. This yeast grows to high densities in fermenter cultures, and simple molecular biology procedures allow foreign genes to be highly expressed in Pichia from regulated or constitutive promoters. Unlike bacteria, Pichia is efficient at synthesizing, modifying and secreting eukaryotic proteins. Sequencing the Pichia genome will dramatically enhance the utility of this yeast. Even a partial genome sequence will allow Pichia to be reengineered to reduce endogenous proteolytic activity, increase the transcription and translation efficiency of foreign genes, and improve the folding and export of secreted proteins. Moreover, the Pichia genome sequence will pave the way for creating strains that synthesize more "mammalian-like" oligosaccharides. A genome database will also stimulate basic researchers to study Pichia cell biology and to develop improved techniques for manipulating this yeast. Therefore, sequencing the Pichia genome is vitally important for the future development of this organism as a protein expression system. | |

| Title: Command Performance: New Technology for Assessing Direct Leadership Abilities | |
| Abstract: In the future, relatively junior leaders will face broader responsibilities. To predict and guide more rapid development of command leadership ability, it is necessary to know what personal attributes and experiences mold it. We will construct a novel battery of accurate, objective direct-leadership assessments to predict performance in real world settings. The centerpiece is a command situation simulator, Command Performance. This simulated environment for direct-leadership performance adapts two new scenario-based leadership training and assessment technologies: Think Like a Commander discussions among senior officers, and Tacit Knowledge for Military Leadership interpersonal command skills of platoon, company and battalion leaders. Command Performance will be a 3midway measureý. its data related both to potential predictors among the extensive background information on USMA graduates in BOLDS, and to performance in real world settings such as led-unit results and NTC transcripts. A unique and critical capability of the project is Latent Semantic Analysis, a machine learning technology that accurately simulates human understanding of ordinary text discussions, verbal reports, recommendations, and transcripts, along with powerful data mining for predictive background variablesWhen fully developed, Command Performance will be offered by Knowledge Analysis Technologies directly to the Army as an ADL enabled leadership assessment and prediction technology. It will also be suitable for adaptation for use in other DOD branches, corporate leadership training, and educational applications such as business and public administration. The latter commercial applications will be developed and marketed by joint ventures between Knowledge Analysis Technologies and one or more of the distance education and corporate training organizations with whom we have now or will develop arrangements. The partner's and their client's knowledge of content will be used to adapt the system, and the partner's market reach to commercialize it profitably and for wide social benefit. The LSA-based data mining and analysis techniques for personnel and student records that we develop may also find commercial application. Finally, Command Performance, coming originally in large part from an environment intended for training rather than assessment as such, will adapted fopr that use as well and commercialized through the same channels | |

| Title: Fundamental Studies of Self-Induced Waveguides in the Atmosphere at Various Wavelengths and Pulse Durations | |
| Abstract: We propose a fundamental study of filamentation in air that will combine the theoretical expertise at the University of Arizona in simulating these nonlinear phenomena, the experimental facilities at the University of New Mexico in ultrafast diagnostics, and the experience at Lite Cycles, Inc. in the design and construction of high-power, short-pulse lasers. In Phase I of this program, we will make measurements of air parameters at various wavelengths to refine the simulation. We will perform direct spatio-temporal measurements on IR and UV filaments by letting them diffract in a vacuum chamber sealed by an aerodynamic (supersonic) window. This technique will enable us to make measurements on pulse parameters inside the filament, which are not affected by nonlinear effects usually occuring at a solid reflecting interface. We expect that the combination of measurements and simulation will enable us to get a complete understanding of the self-trapping mechanism in air, and thus select the best wavelength to be used in Phase II of the program.This project will have applications in creating a remote bright point source for lidar applications as well as for wavefront correction. | |

| Title: Ultraviolet/Infrared Detectors for Active Protection | |
| Abstract: The ARMY needs active protection using a UV and IR dual band focal plane array (FPA) to detect and track hostile fire so that targets can respond and avoid incoming rounds. The objectives of this effort are to determine the requirements of an uncooled UV/IR FPA for active protection and demonstrate feasibility of integrating UV and IR detector arrays with the readout integrated circuit (ROIC). In this FPA approach the UV and IR detector arrays are grown on the ROIC and monolithically interconnected to the ROIC without hybrid bump bonds. Specific tasks are to determine the requirements for active protection, grow UV structures on Si wafers and ROICs, fabricate UV device structures on Si wafers and ROICs, and provide a monolithic dual band process.Dual band UV/IR arrays would primarily benefit military applications. However separate uncooled LWIR and UV arrays are attractive for analysis of products and processing, guidance of automobiles, navigation at sea, unmanned aerial vehicles, search and rescue, fire detection and containment, surveillance systems for drug traffic and border control, and rifle night sights. | |

| Title: Multiband Fluorescence Imaging for Wide Area Detection of Land Mines, Unexploded Ordnances, and Other Contaminants | |
| Abstract: NEWTEC Remediation Services, Inc. recently field demonstrated a new technology for the wide area detection of UXO. The technique was originally developed for landmines, but works for all types of ordnance or associated explosive waste (EW) products. It depends on the leakage of explosives from UXO items, resulting in a concentration on the surface of the soil over the hazard. The detector of this subtle signal is a strain of benign soil bacteria that has been engineered to detect trinitrotoluene (TNT) and respond by producing a fluorescent protein, making a detectable fluorescent mark on the ground. Using a laser, the fluorescent emissions are detectable. The laser produces real-time imaging of the fluorescent signatures on the actual terrain in the field. New breakthroughs have occurred since the original field demonstration. Spectroscopic investigations showed that a new variant of the fluorescent protein gives better contrast between bacterial and background fluorescence, particularly in plants. Additional research has resulted in plants that emit a fluorescent protein expression. Plants offer an attractive complement to the bacterial vector since certain plants efficiently absorb ground based explosive chemicals through their root systems. The fluorescent protein is then expressed over the broad area of the plants leaf canopy. An airborne detection platform is the objective for the field deployment of this new technology.NEWTEC Remediation Services, Inc. is commercializing the use of fluorescent bioreporters in several fields-of-use (FOU's). The primary and near term goal is the detection of explosive hazards and waste at UXO sites, and the detection of landmines in other countries. The NEWTEC-RSI objective is the creation of site survey and soil characterization information to enhance the efficiency of UXO remediation projects for land reclamation and reutilization initiatives. We will also establish broad area detection information to promote demining operations for major infrastructure projects such as oil and gas pipelines, new roadways, and utility lines. A secondary, and a more highly visible global benefit, is the refinement of the process as an area reduction/wide area detection tool for humanitarian demining operations. NEWTEC-RSI with its growing family of biological and phyto-detection capabilities, will be able to expand into several additional market areas. These include, but are not limited to: ú Monitoring gas and oil pipelines for leaks ú Phyto detection and remediation of chemicals ú Industrial Security ú Agricultural Crop Surveillance ú Livestock Surveillance and Animal Healthcare ú Bio-technical Medical Research and Pharmaceuticals ú Base Realignment and Closure, and Formerly Used Defense Site Remediation | |

| Title: A Multiband Wide Area Fluorescence Detection System | |
| Abstract: Nomadics has been working with landmine detection technologies since 1998. During that time we have established the extreme sensitivity of an amplifying fluorescent polymer (AFP) that has been employed in the direct detection of ultratrace quantities of chemical signature compounds of explosives and effective methods of fluorescence measurement including standoff detection. These methods have the potential for use with developing sensors based on the use of microbes for detection of explosives. Together, these technologies offer tremendous potential for locating landmines, unexploded ordnance, and other explosives. Nomadics is collaborating with Oak Ridge National Laboratory to meld these complementary technologies to prove the feasibility of this approach.Besides wide-area screening for landmines and UXO, this technology has the potential to provide detection of other chemical and biological contaminants, such as releases of environmental pollutants and toxic wastes. For example, with specific microbes, large underground storage tank fields could be monitored for leaking containers. | |

| Title: Novel Assessment Tools for Empirical Determinants of Direct Leadership | |
| Abstract: Solus Biodefense and George Mason University proposes to develop an assessment battery measuring Army junior leader attributes, adaptability skills, developmental work experiences, and leadership effectiveness. Anticipated changes in the U.S. Army's operating environment argue for the ascendant importance of leader attributes that promote complex problem solving and adaptability. The Army will also need to develop these qualities in their junior officers more quickly as the demand grows for high quality officers capable of performing in the increasingly dynamic and complex battle environments of the future. The proposed assessment battery, based on conceptual models of leader performance and leader development, will include novel and objective measures of these attributes, and will allow for the assessment of leadership in real time, real world settings, using the internet and other digital technologies. The proposed battery is intended to be part of a longitudinal Army leader assessment program. An integrated effort would link the measures in the proposed battery with those in other ongoing assessment programs (e.g., Baseline Officer Longitudinal Data Set (BOLDS)), and would provide an assessment of leadership growth and development across an officer's career. The expectation is that the assessment battery will assist the Army in training, assessment, and development of its officer corps. The techniques and methods developed will be generic in the sense that, with domain and process specific modifications, they be applicable to other DoD services and, more generally, to leadership development in non-DoD and non-government service sectors, including perhaps K-12 education. | |

| Title: A Monolithic Uncooled Ultraviolet/Infrared Detector Array Capability | |
| Abstract: An optoelectronic integrated circuit combines intersubband infrared and wide bandgap ultraviolet absorption in one pixel with an integrated output. Currently, QWIPs employ a doped multiquantum well structure sandwiched between n+ type contacts. The quantum barrier limited dark current flow requires cooling to 60K for BLIP performance and the QWIPs are hybrid bonded to a Si ROIC for electrical access. In this proposal the intersubband process occurs in a modulation-doped quantum well, so the dark current is generation across a wide-gap semiconductor. No cooling is required because the low dark current allows room temperature BLIP operation. In addition, the wideband material surrounding the quantum well enables UV detection. Thus UV and IR sensing occur in the same pixel. Both the IR and the UV detection mechanisms integrate electrons in the empty well at a inversion-channel interface which is the storage section of a CCD or active pixel with a dedicated output amplifier. The pixel is co-located for both wavelengths so that the IR and UV signals are accessed sequentially. The approach has high pixel density, low noise, reduced power dissipation, circuit size and radiation resistance and manufacturability. In this STTR the dual detector will be demonstrated as an active pixel or CCD.Uncooled CCD arrays with simultaneous IR and UV detection with seamless integrated electronic designs open the door to a wide array of low cost commercial and government product lines that include but are clearly not limited to systems for ultra-high resolution night vision, atmospheric monitoring, medical imaging, thermal sensors, photolithography, and automated manufacturing monitoring. | |

| Title: Breathable Butyl Rubber for Chemical Agent Protection | |
| Abstract: Defense against chemical weapons is a critical DOD requirement. An effective defense requires the development of unique clothing systems that are a physical barrier to toxic vapors, liquids, and aerosols. In addition, the protective material must be permeable to water to reduce incapacitating heat stress, and must be lightweight, flexible, and cost effective. Materials currently in use by DOD are effective barriers to chemical and biological weapons but they are not permeable to water vapor and produce dangerous heat stress and are bulky, severely reducing maneuverability and the overall effectiveness of the wearer. TDA Research, Inc. proposes to develop a breathable protective clothing material from polymerizable surfactants and butyl rubber. The surfactants will form a continuous porous structure with nanometer scale pores large enough to allow water vapor to pass while preventing chemical agents from reaching the wearer. Our approach will use a unique family of polymerizable surfactants and an innovative two step process for forming stable nano-porous structures in the vulcanized butyl rubber. The porous structure of cross-linked butyl rubber films will be characterized and the permeation of water vapor and chemical warfare agent simulants will be quantified.The development of a breathable clothing material for chemical agent protection would be a very significant benefit to the armed forces and civilian defense. Currently, individuals wearing a protective suit are very limited in the amount of physical activity they can endure without the use of a cooling vest or external air supply. The commercial application of this technology would be to manufacture clothing materials for garments produced for the armed forces and civilian defense as a means to protect against chemical warfare or terrorism. Additionally there will be markets for personal protection in industries that handle or produce dangerous chemicals. | |

| Title: Remote Sensing and Directed Energy Applications of Femtosecond, Terawatt Lasers. | |
| Abstract: TDC/UDRI will undertake development of a physics based model for the propagation of terawatt, femtosecond laser pulses through the atmosphere. Previous experiments and theoretical results have made it clear that a new approach must be taken in order to have an unambiguous understanding of this high power ultrashort laser pulse propagation problem in the atmosphere. Simple extensions of the nonlinear Schr”dinger equation will not suffice to make definite and significant progress on this problem. The program will significantly enhance the simulation and modeling capability for the field of intense ultrashort laser propagation. Our approach is based on rigorous multiple?scales expansions of the vector form of Maxwell's equations and the resulting equations will incorporate important nonlinear effects, as well as, vector fields, non-paraxial, space-time focusing phenomena, and plasma generation. We will not assume radial symmetry and we will incorporate sub-gridding into the computations. Where the computations become too memory intense for a single computer we will explore implementing parallel computational methods into our code. The resulting model will provide for verifiable analysis of the details of pulse propagation as a function of initial and boundary conditions, as well as, providing a clear path for Phase II experimental investigation and verification.This effort will result in a model that, when verified by experimentation, will serve as the basis for development of novel, long range LIDAR systems. These systems will be used to detect chemical/biological agents at long ranges, as well as provide a means for remote detection of atmospheric chemicals and aerosols for monitoring of pollution. These advanced LIDAR systems may also be used to remotely measure atmospheric turbulence, providing improved, early alert of wind-shear to landing aircraft. | |

| Title: Bioengineered Proteins for Chemical/Biological Defense, Protection, and Decontamination | |
| Abstract: This proposal encompasses a facile method for generating transgenic chickens. Traditionally, the approach to accomplish this has been to target the avian egg or embryo for gene insertion using either viral or 'standard' plasmids as vectors. In contrast, our proposed method introduces two new features, i.e. (1) novel transposon DNA vectors and (2) injection of DNA into the testes of immature males. As a result, the injected genes will integrate into the genome of some proportion of spermatogonia and this transforms a significant percentage of the eventual mature spermatozoa for transmission by normal breeding to the next generation. This procedure is expected to produce much higher efficiencies n the production of true germline transgenic offspring. Enhancement of integration of the injected trangene construct is accomplished by transposon vectors, which forces integration into the genome of forming spermatogenic cells, as demonstrated in fish by the Co-Investigator. Thus, this STTR proposed research is an extension of previous work, which is now applied to avians. This simple and efficient methodology should facilitate generating transgenic poultry which secrete large amounts of recombinant proteins into their egg whites, thus providing a method of large scale, low cost protein manufacturing.At the end of Phase I we anticipate having 1- 10 true germline transgenic chicks which, after breeding, should demonstrate not only a new method for transgenesis but also provide the groundwork for a new industrial niche using birds as large scale bioreactors to produce the myriad of recombinant proteins needed in the near future. TransWestTech, Inc. plans to be one of the pioneers in commercializing this technology to allow the production of large quantities of low cost proteins by contract, Once this approach has been confirmed, it should be possible to generate millions of transgenic hens within 18 months, each of which could secrete up to a gram of protein into each egg, at a cost of about $.05 each. A small number of contract poultry producers could therefore produce multi-kilogram amounts of protein- pharmaceuticals annually for an estimated finished price of less than $1/gram | |

| Title: Breathable Clothing Material for Chemical Agent Protection for the Soldier | |
| Abstract: This proposal entails the fabrication of selective permeable reverse microemulsion derived elastomeric membranes which are fabricated using rapid prototyping (RP) techniques. Rp offers a significant advantage in that it is capable of forming membranes having controlled porosity and microstructural architectures on a three dimensional level rather than the two dimensional level attained by conventional membrane fabrication routes. Furthermore, this work also details the synthesis of new, high flexibility liquid crystalline copolymer membrane materials exhibiting predicted lower permeability than conventional butyl elastomer.The ability to fabricate transparent controlled porosity and selectively permeable membranes will have tremendous commercial utility. First these materials could find use in chemical process industries as improved gas or liquid purification/separation membranes. An example of this could involve the removal of trace organics from water or water impurities from engine oil. These membranes could also be used as an effective means of separating viruses or bacteria from drinking water. Finally these selectively permeable membranes may find use as bandages for severe burn victims due to its ability to readily allow perspiration evaporation yet prevent dirt contact with the wounds while they heal. | |

| Title: Development of a Truly Lattice-Matched III-Nitride Technology for | |
| Abstract: Cermet, in collaboration with researchers at Georgia Institute of Technology, proposes to implement a lattice matched III-Nitride technology using existing substrates. The implementation of a lattice matched substrate promises to produce near dislocation free III-Nitrides for the first time while the use of an existing substrate technology dramatically lowers development cost and reduces the development cycle. Specifically, we propose to use existing semiconductor substrates to grow lattice matched InGaN to produce superior optoelectronic/electronic devices. The target composition of InGaN will result in the lowest wavelength emitters possible without the necessity of expensive UV-grade optics, has highly efficient emission, and should lead to improved mobility in transistor devices. Highly efficient, vertical current nitride LEDs and FETs will be demonstrated early in Phase II, based on the successful completion of phase I objectivesThe successful completion of Phase I goals will demonstrate the utility of using this technology to improve the performance of high frequency electronic devices and short wavelength LED's, laser diodes, and detectors. | |

| Title: Better GaN substrates through HVPE on bulk AlN substrates | |
| Abstract: Single-crystal aluminum nitride substrates will be used for epitaxial growth of GaN by hydride vapor phase epitaxy (HVPE). The relatively close match in crystal structure, in chemical compatibility, and in thermal expansion should allow much high quality (and much thicker) GaN layers to be grown. HVPE will allow these GaN epitaxial layers to grown cost effectively.Extremely high power microwave and millimeter wave devices will have extensive applications in both the DoD (such as AMRFS) and in civilian applications (such as wireless). The use of aluminum nitride (AlN) substrates with high quality GaN epitaxial layers will accelerate this development. In addition, epitaxial GaN on AlN substrates may be extremely valuable for uses in high temperature electronics for propulsion applications, for space electronics where radiation hardening is imperative, and for uv solid state emitters and detectors for missile defense, optical communications and data storage. Because of the anticipated benefits for improved nitride epitaxy on AlN substrates, there is great commercialization potential for their use blue/uv laser diode fabrication for use in data storage (such as high density DVD) by reducing the manufacturing costs over competing substrates. | |

| Title: Growth of AlN Crystals | |
| Abstract: The objective of this proposal is to demonstrate the feasibility of growing centimeter-size aluminum nitride (AlN) crystals by subliming polycrystalline AlN in nitrogen atmosphere, and to demonstrate single crystalline quality meeting or exceeding the standards of commercially available SiC wafers. The growth process, which utilizes high temperature, subatmospheric pressure and a steep temperature gradient, promises to yield high-purity AlN crystals at commercially interesting growth rates. The growth of small AlN crystals has recently been demonstrated at North Carolina State University (NCSU). Through the proposed research, Hexatech, Inc. plans to increase the size of AlN bulk crystals into the centimeter range, without compromising crystal quality. The properties of grown crystals will be evaluated at NCSU and will include (1) microstructural analyses (optical and scanning electron microscopies, x-ray diffraction, Raman spectroscopy), (2) chemical analysis (X-ray photoelectron spectroscopy), (3) identification of impurities (secondary ion mass spectroscopy, photoluminescence, optical absorption), and (4) study of electrical properties (I-V, Hall measurements).AlN wafers that eventually will be fabricated from the grown crystals will find an immediate application as lattice-matched substrates for high-quality epitaxy of III-nitrides and will enable the fabrication of superior quality AlGaN electronic and optoelectronic devices, including high-frequency amplifiers and switches, blue and UV solid state lasers, solar-blind UV detectors, and surface acoustic wave (SAW) devices. Since the epitaxial processes and a variety of III-nitride device structures have been developed during the past ten years on less favorable substrates with large lattice mismatch, the penetration of these new AlN wafers into the market place can occur without delay and to the immediate benefit of device performance. | |

| Title: Narrow-linewidth, Sol-Gel Glass/Photopolymer Holographic Filter Technology | |
| Abstract: Hybrid Technologies (HT, Amherst, NY) in cooperation with the Institute for Lasers, Photonics and Biophotonics (ILPB) at the State University of New York at Buffalo proposes to develop new bulk glass-photopolymer materials and investigate the feasibility of using them for high efficiency, permanent, highly wavelength selective holographic gratings needed for Dense Wavelength Division Multiplexing (DWDM) and other applications. In this program, HT proposes to utilize novel sol-gel glass/photopolymer composite technology based on the recently developed MEMPLEXr photopolymer. Holographic gratings recorded in MEMPLEXr materials have demonstrated very stable index modulations due to photoinduced chemical reaction and very high coupling constants (dynamic range). Processes to further improve these materials by fabricating hybrid glass/photopolymer composites are proposed. Use of these gratings as highly wavelength selective filters, operating at the visible and NIR (e.g., communication) wavelengths, will be investigated along with new methods for grating recording. HT expects that this program will culminate with new technology for fabricat | |
