| Title: | Fiber optic water corrosivity monitoring system |
| Abstract: | Water piping systems maintenance is challenging due to cost and difficulty of maintaining optimal water chemistry. Advanced corrosion control systems are needed to actively monitor water corrosivity as feedback for the injection of green chemicals to maintain optimal water chemistry. Advanced corrosion control for water piping systems will result in reduced manpower costs and increased component life cycles. The Department of Defense estimates that a 1% improvement in Army utility O&M performance can save $18 million per year. To address this critical military need, Luna Innovations proposes to develop an optical fiber-based real-time water corrosivity monitoring system. The Phase I program will focus on the development and demonstration of the proposed sensor technology. The focus of the Phase II program will be to optimize sensor performance and validate performance through field testing. Luna has assembled the highly qualified, multidisciplinary team required for a successful program and has a history of bringing novel research from the laboratory to commercial markets. |

| Title: | A Water Sealant with Anti-microbial Functionality Developed for Concrete Surfaces and Deposited by Electrophoresis (7265-060) |
| Abstract: | Physical Sciences Inc. proposes to electrophoretically deposit a coating of lithium silicate and photoactive titanium dioxide nanoparticles onto concrete providing a totally inorganic, room-temperature cured, concrete sealant. This coating scheme will be shown to not only reduce water permeability but will also benefit from the antimicrobial properties of the reactive titanium dioxide nanoparticles. The photoactive nature of the titanium dioxide will inhibit bacteria, mold, fungus, and algae growth on the concrete surface providing added long-term benefit. Phase 1 will validate the advantages of the proposed method via reduction in water permeability and demonstration of the anti-microbial functionality of the coating. |

| Title: | Investigation of Electrophoresis as a Novel Coating Mechanism for Sealing Concrete |
| Abstract: | The U.S. Government is a heavy user of concrete structures for below-grade facilities, waterway, and marine applications. High hydraulic permeability of the concrete in these structures produces water intrusion into protected areas and accelerated corrosion of structures beyond their useful limits, necessitating costly maintenance, repairs and replacement. In response to this overwhelming problem, SHOT proposes to develop a novel coating system that uses electrophoresis for sealing concrete. Our research suggests that through an electrophoretic process, nanometer scale particles can be migrated into hardened cement paste, resulting in dramatically lower hydraulic permeability. Our previous experience in developing electrophoretic hardware provides an ideal foundation for the development of new hardware for application of this unique process. Our team will design and develop an ideal sealant/coating solution, as well as the equipment required to test coated concrete samples for their hydraulic permeability. The results of this testing and analysis will guide SHOT in designing equipment and optimizing the treatment coating solutions. The end product expected is a viable and effective concrete coating system we have called the SHOTr Electrophoretic Sealing System, which we plan to market under the trade name E-Seal. |

| Title: | High Frequency Pulse Reverse Electrochemical Treatment of Concrete for Mitigation of Corrosion |
| Abstract: | This Phase I SBIR program addresses the critical need for effective dechlorination methods for corrosion protection of bridge deck and piers at US Army facilities. This program proposes an innovative electrochemical technology for dechlorination of concrete, which is cost-effective and suitable for large scale field applications, and adaptable to complex geometries while protecting the rebar within the concrete from further corrosion. The Phase I program will show that the proposed technology will remove chloride contaminants from concrete under an applied high frequency pulse reverse electric field, and accelerate the mass transport rate of ions, lowering operating costs and treatment times. To protect the rebar from corrosion during and after this process, corrosion inhibitors will be driven into the concrete structure using the applied electric field, and the rebar will also be protected using a pulsed cathodic protection system. The project team consists of Faraday Technology, Inc., an electrochemical engineering company that develops high frequency pulse reverse processes, and Terran Corporation, an environmental engineering firm specializing in the field installation and monitoring of direct current (DC) electroosmotic and electrokinetic remediation processes. The Phase I results would be transitioned into field trials in a Phase II program. |

| Title: | Intelligent Coatings for Self-Healing and Corrosion Control |
| Abstract: | The bulk of current military coatings are expensive, contain volatile organics, and are labor intensive to apply. Much of these costs are associated with the scraping and repainting of metal materials (20% of the $10 billion in estimated Army corrosion-related costs). There is a tremendous need to develop intelligent coatings that can perform numerous functions above those historically demanded of coatings. Luna is addressing this need to enhance the service life of steel structures by developing an intelligent coating that will respond to a damage event to the coating and release (1) film-formers to heal the wound, (2) corrosion inhibitors to provide additional corrosion prevention to the site, and (3) passive indicators to mark the coating damage zone to alert maintenance personnel. In this Phase I SBIR, Luna will combine our recent successes in corrosion prevention, water-borne resin development, and specialty coating formulations chemistry using microcapsules to design a unique coating system that has the potential to meet multiple damage challenges to the same location. |

| Title: | Silica-Based Corrosion Protection Microcapsules |
| Abstract: | Painting metal provides excellent corrosion protection, as long as the paint remains intact. However, if the paint peels or becomes chipped after an impact, corrosion can occur in the revealed metallic area and even spread underneath the paint. Therefore, regular inspection and maintenance are required to ensure that the paint remains undamaged. Repairs may be required for damage that occurs between inspections. As an alternative microcapsules incorporated in the paint can be used to store film-forming and corrosion preventative agents. When the paint is damaged, these agents are released and reform the paint before corrosion occurs. While microcapsules to incorporate water-insoluble pigments, organic monomers and organic corrosion inhibitors have been demonstrated, there has been little work with ionic, water-soluble corrosion inhibitors. Nomadics will apply our extensive experience in advanced materials to use silica-based microcapsules that contain water-soluble materials to supplement polymeric-capsules containing organic materials. These additives will help to achieve self-healing coatings that will have numerous applications in military and private sector applications. |

| Title: | Concrete Admixtures that Defend against Salt Scaling and Freeze-Thaw |
| Abstract: | In cold climates, concretes are susceptible to deterioration from the combination of the use of deicing salts and cyclic freezing and thawing cycles. The presence of salts is reported to exacerbate the susceptibility of concrete to freeze-thaw deterioration. IPANEX is an admixture that has been in use for nearly 30 years and has a long track record of compatibility with plasticizers and air entraining admixtures. The mechanism by which IPANEX functions, however, has only recently been established. With the development of the understanding of how it works has come greater insight into applications beyond the initial scope of its usage. IPANEX is composed of 5 to 20 nanometer-sized particles of C-S-H [hydrous calcium silicate] that in application, seed the growth of C-S-H from the hydration of tri-calcium silicate. Seeding with nanometer-sized seeds means that a small dose rate will result in a large number of seeds distributed throughout the mass concrete. These seeds have the effect of removing the supersaturation that occurs with tri-calcium silicate and providing a more homogeneous microstructure. As part of this refined microstructure, there are no large growths of calcium hydroxide crystals; not even at the aggregate low density zones. The controlled growth does not necessarily result in less pores but rather in a pore structure that is generally finer. IPANEX will impact any process that relies upon the movement of fluids [water or gases] through the pore system of a concrete. As water freezes, it draws additional fluids from the gel pores, if the critical concentration of water in capillary pores is less than 91.7%, or if water can not be drawn from the gel pores, freeze-thaw deterioration will not be a problem. Furthermore, because of the pore sizes, water will not freeze in capillary pores. One school of thought on freeze-thaw deterioration suggests that osmotic pressures which develop between the freezing water in large pores and the capillary porosity result in different alkali concentrations and hence different pressure is a more or less significant contribution to this mode of deterioration. It is however considered as a major factor in salt scaling. The objective of this SBIR will be to demonstrate that IPANEX is compatible with air-entraining admixtures and will improve the durability of the concrete to salt scaling through the improvement in the microstructural development of the concrete. |

| Title: | Low Cost Corrosion/Corrosivity Sensor Systems For Ground Vehicles |
| Abstract: | This proposal develops an extremely low cost fiber grating corrosion sensor system that could be deployed on a vehicle. Costs are estimated to be approximately $0.25 per sensor in volume allowing hundreds to be deployed if necessary on difficult to access areas of a ground vehicle. In order to keep costs to an absolute minimum it is anitipated that the read out unit would be maintenance rather then vehicle based. The system has the ability to be deployed and operated over a very wide range of temperatures and offers inherent temperature compensation. Because it is passive and dielectrically based it has very long potential life, limited mainly by corrosion of the material it is measuring. |

| Title: | Low-Cost EIS Corrosion Sensor for Ground Vehicles |
| Abstract: | Corrosion of Army ground vehicles is a significant problem in cost, reliability, readiness, and safety. In many cases, the design of the vehicle relies solely or extensively on the protectiveness of the paint system for corrosion protection. DACCO SCI and Advanced Fluidics propose to develop a low-cost corrosion sensor system (sensor + electronics) that can directly monitor the coating health at the motor-pool level. In particular, this sensor system will provide early warning that the coating performance is degrading in contrast to corrosivity sensors that merely measure the corrosivity of the environment. The sensor is based on electrochemical impedance spectroscopy (EIS), which has proven successful in the laboratory for predicting coating performance. The sensors allow EIS to be performed in the field as a health monitoring method. The electronics module will mount on the vehicle and will transmit its signal to a hand-held device and alert the motor-pool soldier of coating damage or deterioration so that preventative maintenance can be scheduled to forestall serious structural damage due to the corrosion. The result will be decreased maintenance and replacement costs with increased readiness and reliability. |

| Title: | Ultra low cost wireless corrosion sensor for ground vehicles |
| Abstract: | The Army spends an estimated $2 billion to $2.5 billion per year addressing corrosion-related issues with Army ground vehicles. Corrosion also has a significant impact on force readiness. Army ground vehicles that require corrosion-related repairs are typically out of service for many months. Corrosion has also been shown to dramatically shorten vehicle life. Low cost and easy-to-use corrosion/corrosivity sensors offer the potential to dramatically reduce vehicle life cycle costs and improve readiness. Knowledge of corrosion state and environment enables more effective corrosion mitigation and prediction. To address this critical defense need, Luna Innovations proposes to develop a corrosion/corrosivity sensor system specifically designed for the rigorous operational environment of Army ground vehicles. The proposed system will be ultra low cost, passive and wireless. It will be based on commercially available technology, will not require wired or battery power, and will enable remote interrogation and placement where needed around the vehicle. Luna has assembled the highly qualified, multidisciplinary team required for a successful program and has a history of bringing novel research from the laboratory to commercial markets. |

| Abstract: | The P2SI team objective in this proposed research effort is to develop an inherently corrosion resistant composite/metallic joint design. As coatings and sealants deteriorate in service the joint will be inherently corrosion resistant. This will be achieved through a thorough understanding of how the fundamentals of galvanic corrosion relate to corrosion susceptibility of the F-35's composite-metal joints. In this effort, we will experimentally validate our approach using parameters from the F-35 baseline design. The P2SI approach will identify composite-metallic joint configuration dependent and independent variables that directly affect the potential for galvanic corrosion. We will investigate the corrosion rate and effect of corrosion on joint integrity and strength. This will enable us to establish allowable tolerances for design and manufacturing that will protect joints from catastrophic galvanic corrosion failure, even in the event of coating and sealant deterioration in service. In Phase I, multi-variable regression analysis will be performed on the data to model observed effects. We will perform environmental exposure, detailed corrosion and corrosion rate analysis, and residual mechanical property measurements on F-35 joint-based specimens. This approach will ensure maximum relevance of the data and modeling performed under this effort towards state-of-the-art airframe structural design and analysis. |

| Title: | New Corrosion Inhibiting Cleaning System for Aluminum Alloys |
| Abstract: | Precoat surface cleaning of aluminum alloys is critical for removing common surface contaminants such as loose metal oxides, oils, and dirt that can impede wetting and adhesion of subsequently applied coatings. Many caustic cleaning processes cause matrix dealloying/redeposition of copper, which often results in copper on the aluminum alloy surface and localized corrosion initiation. A new cleaning process is proposed that effectively removes the surface contaminants and poorly adhered oxides while minimizing the corrosion-inducing redeposition of copper smut. The objective of the Phase I program is to identify candidate metal pretreatment systems which meet the goals of low toxicity, simple application, effective surface cleaning, passivation and copper-redeposition prevention for enhancing corrosion inhibition. A novel combination of surface-active compounds, inhibitors, and anti metal redeposition agents will be used to formulate the new aqueous-based cleaning systems. These pretreatment systems and suitable controls will be tested on common aircraft aluminum alloys for cleaning efficiency, inherent corrosion inhibition by potentiodynamic electrochemical analysis, compatibility with conversion coating application and paint adhesion. The costs, hazards, and environmental fate of effluents produced by the new cleaning processes will be estimated and used in the system design. |

State-of-the-art electrochemical techniques will be used to quantify metrics of corrosion susceptibility that will facilitate objective evaluation of the various cleaning method. Evaluation will be done in comparison to a control cleaning method based on existing specified treatments. |

| Title: | Improved Aluminum Cleaning Method to Prevent Copper Enrichment |
| Abstract: | Since pure aluminum is soft and has only moderate strength, aluminum alloys are used for aerospace and other structural applications. However, the copper in these alloys significantly reduces the corrosion resistance of the aluminum. The standard pretreatment used to clean aluminum alloys before painting or coating enriches the surface of the aluminum with copper, creating sites for corrosion. An ideal aluminum cleaning procedure would degrease and deoxide the surface without dealloying the copper and allowing it to redeposit on the surface. In this Phase I proposal TDA will develop an additive for surface pretreatment cleaners that prevents copper enrichment during pretreatment of high strength aluminum alloys. |

| Abstract: | Deployable space structures are becoming increasingly important assets for use in the battlefield. Communications, global positioning, unmanned air vehicles and tracking and surveillance of enemy troops are creating an enormous demand for space borne assets. Structures that can package efficiently meet many of the needs of creating larger apertures for the high bandwidth military missions. We propose to demonstrate a novel high temperature dyed Colorless Organic/Inorganic Nanocomposite polyimide (CORIN) material. The material will be synthesized for coating PBO fibers and sheets to prevent VUV, UV, and AO degradation. The base polyimide has been successfully flight qualified, and transitioned for products on NASA, DoD and commercial satellite communications structures. Phase I results will be to demonstrate a scaleable process for applying coating materials to Polybenzoxazole fibers. Mechanical quantification of the material coating will be performed to demonstrate the adhesion of the polymer to the fiber during repeated cyclic stress and thermal loading. A key aspect of the proposed effort is transition of the coating process from a laboratory scale to production oriented processes. Our process will be demonstrated in Phase I for coating fiber and yarn materials to be scaled to production level processes in Phase II. |

| Abstract: | There exists a need to identify and develop various coatings that can be used in the protection of polybenzoxazole (PBO) materials. PBO has exceptionally good strength-to-weight ratio and temperature stability. PBO fibers have been identified for a variety of space applications. These applications consist of, but are not limited to, power generation, orbital maneuvering, and planetary exploration. For example, momentum exchange (MXER) tethers utilize the physics of momentum transfer to catapult a payload out of the Earth's gravity well. This tether system requires space durable, high strength-to-weight ratio fibers. Tether materials-related advances are primary for improving the operation and lifetime of the propulsion system. Critical materials properties in need of improvement include increases in tensile strength, electrical conductivity, shock resistance, continued flexibility during exposure to an environment rich in radiation and energetic atomic oxygen. PBO films and solids have been proposed for use as lightweight structural materials for satellite housing and other spacecraft systems. In this program, Triton Systems will develop multiple space durable protective coatings for PBO. |

| Abstract: | Polybenzoxazole polymers, including polyphenylenebenzobisoxazole (PBO) in particular, are under development for use in a wide variety of aerospace applications due to their remarkable tensile strength, modulus, and flame resistance. These materials are of particular interest due to their high strength-to-weight ratio, which allows for a dramatic weight savings when replacing conventional structures. This is particularly significant for in-space applications such as satellites. Satellite components are exposed to potentially damaging impingements, such as ultraviolet (UV) light, atomic oxygen, and fast-moving particles. There is a need for PBO coatings that can increase the functional lifetime of the polymer in the harsh space environment. In ongoing, complementary work, Ultramet introduced a unique and innovative chemical vapor deposition (CVD) technology that relies upon UV activation of the CVD process rather than conventional thermal activation. This low temperature deposition route is ideally suited for coating substrates with relatively low thermal stability, such as PBO. The objective of the proposed project is to assess the viability of this innovative process for scaleable production of coatings that could be effectively used for government and commercial satellite components. |

| Abstract: | As a result of continuing advances in magnetic materials, compression of circuit physical architecture, increase in magnetic component packaging density and faster switching speed, the heat dissipation rate of next generation military power converter systems will require operation at significantly higher heat flux levels than current power converters. The goal of this SBIR Phase I program is the development of novel magnetic materials with optimal characteristics to meet the required high temperature and electrical operating requirements for military power converters. A further goal of this program is the development of a thermal management approach that utilizes a phase change process coupled with the use of a unique high thermal conductivity 3-D carbon structure to meet the power converter heat dissipation requirements. The design of the 3-D carbon structure would be engineered to provide a high surface area to volume ratio heat exchanger element that would enable a compact, light-weight highly effective heat exchanger device. Further, the design of the 3-D carbon structure will ensure that the local heat flux within the active heat exchange device is sufficient to maintain the power converter operation for continuous and pulse power operation. The proposed thermal management concept will be capable of maintaining the magnetic components at or below their required maximum operating temperature, thus, ensuring system reliability and life. |

| Abstract: | The widespread use of battery is severely hampered by low energy density and poor performance of cathode materials of Li-ion battery due to the micron size particles, small surface area, unstable structure during cycle, inadequate mechanical strength, costly precursors, temperature unstable low ionic conductivity etc. The goal of this project is to develop nano-structured cathode material by a novel method that will result in a high energy density of batteries for electric vehicle and other applications. In this phase I effort, to mitigate the deficiencies of the currently available cathode materials, a nanosize Li[NixCo1-2xMnX]O2 cathode materials will be developed. This cathode material has an excellent storage capability. Li[NixCo1-2xMnX]O2 material will be rigorously tested for their electrochemical, thermal, physical and structural properties to insure that it possess the requisite performance characteristics and high energy density at least an improvement of 2X. In Phase II, further testing and development of these cathode materials will be conducted. A prototype of battery with be design with high energy density. In Phase II, a prototype will also be manufactured for field-testing under actual conditions. |

| Title: | High Energy Density Li-ion Batteries With Good Low Temperature Performance |
| Abstract: | High energy density Li-ion batteries that can operate over a wide temperature range are needed in a variety of military, space and commercial applications. The specific energy of Li-ion batteries can be enhanced by utilizing new cathode materials that have significantly higher energy density than that of state-of-the-art LiCoO2. Low temperature performance of Li-ion batteries can be improved by reducing the electrolyte resistance and enhancing the mass transfer across the electrode/electrolyte interface. This can be accomplished by raising the ionic conductivity of the electrolyte and reducing the size of electrode particles, respectively. The proposed program focuses on developing novel nanostructured cathode materials with an energy density of ~ 800 Wh/kg, which is almost 50% higher than that of the practical energy density of LiCoO2. Working in collaboration with a leading developer of Li-ion batteries, in Phase I, we will demonstrate that it is possible to produce a stable high energy density nanostructured cathode by controlling the structure and composition of nanoparticles. As part of the Phase I work, a low temperature electrolyte will be used in Li-test cells to evaluate the electrochemical performance of nanostructured cathodes at sub-zero temperatures. In Phase II, prototype batteries will be fabricated and tested for performance, along with optimization and scaling of the synthesis process for producing electrode nanoparticles. |

| Title: | Nanostructure-Enhanced Bulk Thermoelectric Materials |
| Abstract: | The use of thermoelectric devices as alternative energy sources has been investigated with limited success. Manufacturing costs and limited power generation efficiency have prevented the economical, large-scale production and use of the thermoelectric devices as a viable alternative energy source. Agiltron has proposed an innovative nanostructure-enhanced thermoelectric material that will integrate the synthesis of PbSe nanowires and the fabrication of nanocomposite-enhanced bulk thermoelectric materials. The proposed technologies will include single-phase, highly-crystalline, surface-clean and diameter-controlled PbSe nanowires fabrication; orientation, and densification with ball-milled submicrometer-sized powder of bulk thermoelectric material into nanocomposite-enhanced thermoelectric material through a hotpress technique. The thermoelectric figure of merit of this new nano-composite is predicted to reach ZT = 3 at 300K. This innovative thermoelectric material will have immense application potentials in power generation, energy harvesting, and solid-state cooling and refrigeration. |

| Abstract: | Evident Technologies, Inc. intends on using its core competency in quantum dot synthesis, quantum dot surface modification and quantum dot composites to create cost effective, high ZT thermoelectric thin films that can be deposited onto inexpensive flexible substrates. In the Phase I demonstration project Lead Selenide nanocrystals with a 1-2nm thick shell of PbS will be synthesized using proprietary solution phase synthesis techniques. These quantum dots, initially suspended in solution, will then be self assembled into a colloid crystal on substrate using surface modification and controlled solvent evaporation. Finally the PbS shells surrounding the PbSe quantum dot cores will be thermally fused resulting in a thin film structure having colosely spaced PbSe quantum dots suspending in a PbS matrix. |

| Title: | Nanostructure-Enhanced Bulk Thermoelectric Materials |
| Abstract: | Significant improvement in the ZT (figure of merit) has been recently been reported in thin film thermoelectric materials. These improvements were achieved by taking the advantage of low dimensionality in PbTe-based quantum well and quantum dot systems prepared by MBE and in BiTe-SbTe quantum well systems prepared by MOCVD. However, to become commercially viable new low-cost processing routes are needed for preparing bulk materials that contains nanostructured, thermoelectric active components. The proposed program focuses on development of a nanocomposite thermoelectric material composed of nanostructured "core-shell" particulates. In Phase I, "core-shell" nanostructure PbTe-PbSe will be developed by using a solution based technique, consolidated using colloidal processing techniques and then densified using high energy compaction. The nanocomposite bulk samples for evaluated by Hi-Z, a thermoelectric manufacturer. |

| Title: | Nanostructure-Enhanced Bulk Thermoelectric Materials |
| Abstract: | Compact, solid-state thermoelectric devices are now widely used for both cooling and power generation. These highly reliable devices have no moving parts, operate around room temperature, and are easily integrated into thermal systems. Despite these advantages, engineering applications have been limited by the relatively low intrinsic power conversion efficiency of the semiconductor material comprising the devices. Engineered, nanometer-scale semiconductor materials are now being developed to increase the thermoelectric efficiency. Much larger enhancements in thermoelectric efficiency are predicted in true quantum confined systems since this confinement produces peaks in the density of states. Accordingly, nanometer-sized spheres or rods should offer the highest increase in Seebeck coefficient. It should be possible to fabricate a composite material based on semiconducting nanoparticles that exhibits enhanced thermoelectric efficiency using high electrical/thermal conductivity ratio materials (e.g. conducting polymers) to provide a means for intergrain connectivity between the nanoparticles. To this end, Nanohmics and Drs. Kevin Stokes and Jiye Fang of the Advanced Materials Research Institute (AMRI) at the University of New Orleans propose to develop bulk thermoelectric composites consisting of organized assemblies of thermoelectric nanomaterials and conducting polythiophenes using an automated assembly process. |

| Title: | Nanostructure-Enhanced Bulk Thermoelectric Materials |
| Abstract: | The objective of this proposal is to develop and implement methodologies for new bulk thermoelectric materials that incorporate nanostructural elements to significantly increase the thermoelectric figure of merit, ZT, by way of phonon boundary scattering providing enhanced fuel economy via waste-heat to electrical energy conversion as well as provide stand-alone power from either intentional fuel sources or naturally occurring heat harvesting circumstances. Three primary methods will be used to develop nanostructures within a target thermoelectric alloy (AgPbmSbTe2+m) with the goal of developing a commercially realizable bulk material methodology resulting in high ZT thermoelectric devices. The unique cubic AgPbmSbTe2+m (LAST) structural identity can be exploited to produce nanostructural components that will act as phonon scattering sites within the bulk material. Tellurex's continuing work on the LAST system indicates that structural grain size reduction may be brought to nanoscale through rapid quenching and advanced mechanical powder processing techniques. A scaled sintering regimen will also be developed and employed to induce nanoscale boundary growth providing phonon boundary scattering. These processes will be used singularly and in combined strategies to determine the method resulting in the highest ZT and provide the focus for Phase II and Phase III development. |

| Title: | Lightweight Power Transformer for Shipboard Electrical Power Distribution Systems |
| Abstract: | As with most forms of transportation, ships have weight and volume constraints relative to operational equipment. Conventional transformers, in use to convert high voltage electric power to lower voltages and vice versa, are both heavy and big. With recent advances in semiconductor devices and digital control, "Electronic Transformers" can replace conventional transformers while providing a factor of three weight and size reductions. Electronic Transformers can potentially also provide side benefits such as voltage regulation, power factor correction, VAR compensation, and low harmonics. The proposed Phase I effort will investigate the feasibility of developing such Electronic Transformers. Conventional transformers have the advantage of relatively low cost and high full-load efficiency. Thus, the value of the weight and size reductions, and power system benefits that the Electronic Transformers provide, will have to offset lower efficiencies and potentially higher costs. Systems analyses and trade studies may show that Electronic Transformers compete very well. AeroVironment will overcome the many technical challenges leveraging experience from recent transformer/inductor development projects and digital control development projects. By demonstrating feasibility, we will help enable the Navy to improve shipboard electrical systems operations, while reducing electrical equipment weight and volume claims. |

| Title: | Lightweight Power Transformer for Shipboard Electrical Power Distribution Systems |
| Abstract: | A topology for a medium voltage to low voltage 3-phase power converter is proposed. It consists of a clean power rectifier followed by multiple isolated DC to DC converters using commercially available high frequency transformers with very low core losses when driven by a quasi-resonant inverter operating in the 20 to 50 kHz range. The DC to DC input DC busses are placed in series, while the outputs are in parallel to effect the reduction in voltage from medium to low. Finally a DC to AC inverter re-constructs a 3-phase voltage, which after filtering, provides high quality power for low voltage loads. This proposal defines development efforts to identify the appropriate rectifier topology if clean input currents are required, to build and test a breadboard high frequency transformer, and to refine the design of the output DC to AC inverter and filters. |

| Title: | Lightweight Power Transformer for Shipboard Electrical Power Distribution Systems |
| Abstract: | The objective is to develop lightweight voltage step-down equipment to be used in vehicle power distribution systems, with particular emphasis on the DD(X) and CVN(X) programs. Conventional 60Hz power distribution transformers are large and heavy. The Navy seeks a smaller and lighter replacement technology. The voltage level and operating frequency drive the physical size of a power transformer. High voltage and low frequency yield high magnetic flux and necessitate a large transformer core. Engineering Matters proposes to design, simulate, fabricate and build a transformer-isolated high-frequency switch-mode power supply to replace existing low-frequency transformers. Engineering Matters has already developed a high voltage, high frequency solid-state switch. This switch will enable the power supply to operate directly from primary shipboard distribution voltage (13.8kV) at frequencies above 5kHz. At high frequency, the size of the transformer will be greatly reduced. The core design will be optimized for volume savings, with material to be selected from ferrite, amorphous metal, and advanced iron-based magnetic alloys. The switching power supply will also feature voltage regulation and a high power factor. |

| Abstract: | In Phase I, we propose to design a 300kW DC-DC converter for hybrid vehicles that operates at 92% efficiency, with 100øC coolant inlet temperature, and fits within 50L (6kW/L). Transitioning to the use of Silicon Carbide switching technology when it becomes available should allow increases in power density to 8kW/L. Our unique innovation is using the AC-link power conversion technology, which provides extremely low switching losses and minimal component count. AC-link is a softswitching technology, which minimizes switching losses resulting in reduced active switch and thermal management requirements. AC-link is currently being used in a similar project to build a 250kW power-dense DC-DC converter for the Air Force's Active Denial Technology; these efforts will be leveraged for this project. We will also construct a 10kW bench-scale unit in Phase I to prove the feasibility of the system. In Phase II, we will develop and deliver a 300kW converter meeting the design criteria specified. Dr. Rudy Limpaecher at SAIC and Dr. Tony Mavretic at Siat of Boston Inc. will consult on the project.

| Abstract: | In recent years, there have been significant advances in YBCO coated conductor development. AMSC reported achieving electrical performance levels of 330 Amps, 10 percent above the commercial threshold performance level of 300 Amps set by the U.S. Department of Energy (DOE) for 2G HTS wires. Also, high performance reults were reported on greater than 30-m lengths - triple the length of its previously reported results. In addition, some preliminary work has been performed by MIT and DOE/ORNL on the quench stability in these tapes, primarily for cable applications, primarily for cable applications. However, thre has been little work performed on YBCO coils. Therefore, the purpose of this SBIR effort is to focus on issues related to the design, fabrication and testing of YBCO coils. By studying and understanding such issues as YBCO coil thermal and mechanical properties and selecting preferred methods of insulation, advances in YBCO coil design can be achieved. Furthermore, as progress is made in designing and fabricating low-loss, ac conductors from this material, it is expected that under Phase II, coils can be designed and tested for either a prototype transformer or stator winding. |

| Title: | Superconducting Developments for Compact Power and Energy Systems |
| Abstract: | Superconducting coils are capable of storing considerable amounts of energy. Should a coil quench, due to overheating or exceeding the critical field or current carrying ability of the wire, the stored energy in the coil must be dissipated safely - without endangering personnel or damaging the coil or control systems. In any superconducting coil design, it is essential to design and build the system such that the limits of the materials involved are not exceeded. High temperature superconductors (HTS) are relatively new to applications in magnets and coils, but are rapidly growing in use thanks to advances in conductor performance and availability. However, not much is known currently concerning the quench protection design limits of the materials. Thus far, quench protection in high temperature superconducting coils has been largely overlooked. This has mainly been due to the fact that HTS materials have higher heat capacities at their operating points, and are often difficult to quench. Unfortunately this high heat capacity also creates slow propagation velocities which can cause catastrophic damage to the HTS. New methods for quench protection in HTS coils will be analyzed via computer simulation. |

Light weight magnesium diboride superconductor wire offers the potential of the required magnetic field but will operate at higher temperature of 10-25 K, and be a much lighter weight superconductor. Thus there is the potential to reduce the size and weight of the gyrotron magnet and cryocooler for airborne applications. This SBIR Phase I will demonstrate a sub-size solenoid gyrotron magnet with magnesium diboride superconducting wire, and determine what weight and size reductions could be made for a full size magnesium diboride gryotron magnet and cryocooler. |

| Abstract: | YBCO film through MOD approach is one of the most cost effective methods for long length CC fabrications. Although, this process has shown success on films below 1 micron, thicker films with performance goal of 500 A/cm have not been demonstrated even on small samples. Increasing Ic through further improving Jc is not viable because the present Jcs are comparable to that of the intragrain Jc, which is believed to be theoretical limit of YBCO superconductors. Thicker films of 1-3 microns through MOD approach with pinning center enhancement are yet to be fully developed to attain a higher Ic. High-density nano scale pinning centers is the only way to keep Jc from dramatic degradation for thick films. Thus, in Phase I, we propose to increase thickness while keeping Jc from degradation for higher Ic. Technical approach including thicker film fabrication and introducing high density nano size pinning centers for the MOD YBCO films on both IBAD and ISD templates are designed. By reaction and growth control, thicker films with high density, uniformly distributed small non-superconducting second phase as pinning centers are expected. |

| Abstract: | The manufacture of high energy density capacitors via the formation of high performance dielectric films is of vital importance for high pulse power applications. MSTA,LLC has demonstrated that by means of a modified PECVD technique, high quality polymer thin films have been fabricated, which are pine-hole free, dense, and homogeneous, with a highly crosslinked 3-dimensional amorphous bulk structure, and a smooth surface. This versatile process also performs plasma co-polymerization from monomers with different functionalities, which can manipulate material refractive index and by extension, the dielectric constant and other dielectric properties of the films. Furthermore, the films are also mechanically tough and robust, possessing excellent thermal stability and chemical/environment resistance, as well as good adhesion on different substrate materials and deposition capability on various shapes of the substrates. MSTA, LLC will do research in the application of this methodology to fabricate dielectric polymer films with high breakdown strength (> 800V/mm), moderate dielectric constants (2.5 - 4), and low dielectric loss (0.1% or less at 1 kHz frequency). Throughout the course of this investigation, the structure/morphology of the films will be examined and elucidated by XPS, IR, solid-state NMR, AFM, SEM, TEM, and spectroscopic ellipsometry to provide a scientifically sound basis for the study of advanced dielectric materials. |

| Title: | Low-Cost Quasi-Amorphous Carbon Dielectrics for Pulsed Power Capacitors |
| Abstract: | As our military continues to evolve and become more reliant on highly sophisticated equipment, the need for advanced electronics to support their operation is becoming increasingly more important. Clearly, one of the most important transformations is in the area of weapons systems. In fact, the U.S. Military is developing high energy density, pulse power capacitors to enable all-electric weapons with a goal of one day developing only such systems. The capacitors are required building blocks for pulse forming networks (PFNs), which convert prime electrical energy into short pulses needed to energize loads. Some of the current key research objectives for such capacitors include thin, flexible dielectrics with a high voltage breakdown strength (> 20KV/mil), a dielectric constant greater than 2, and low losses (0.1%). Enhanced processing capabilities with potential for radical improvements in materials properties are urgently needed for the development of advanced capacitors. The proposed SBIR program would make ultrahigh performance dielectrics available through an elegant, patent-protected approach to produce synergetic diamond-graphene quasi-amorphous (QUASAMT) materials. These materials have a high dielectric constant, high thermal conductivity, are extremely strong, can be deposited as thin as 5 nanometers, and can be produced at low cost using standard vacuum deposition equipment. |
