| Title: | Field Chemical Analysis Tool |
| Abstract: | Emission spectroscopy based microdischarge sensors will be adapted to a gas chromatography system for the rapid detection of chemical agents in the field. These systems will be tested to determine optimum column length for seperation and integration time. Microdischarge detectors are rapid, real-time sensors, capable of sub-parts per billion detection of a wide range of atomic and molecular species. They are ideal as gas chromatography detectors due to their small size and low flow requirements, a potetial shortcoming of other available technologies. Additionally, these detectors provide a wealth of spectroscopic data, providing for accurate determination of chemicals present in air, with little chance of false alarms. The entire detection system will be self contained, battery operated, and robust enough for field deployment in its final form. Portable chemical analysis in a hand-held, rugged package will provide a safe effective source of chemical agent detection for protection of the warfighter. A portable, hand held, hazardous chemical sensor will also be applicable for hazmat and fire department use, as well as for the screening of mail, luggage, and security monitoring of buildings. Additionally, the technology developed with this project will be applicable to any situation where size and portability requrements are placed on a chemical analysis tool, suchas in environmental survey applications. |

| Title: | Field Portable GC-MS |
| Abstract: | The instrument of choice for identifying low-level amounts of CW agents and other volatile, highly toxic substances is gas chromatography - mass spectrometry (GC-MS). This analytical tool has the sensitivity required for performing such low-level analyses, and the ability to provide irrefutable confirmation of the identity of a volatile or semi-volatile substance, including CW agents. However, commercially available GC-MS instruments that are rugged enough to withstand the extreme conditions of outdoor environments and are able to provide results in a timely manner cannot also provide analytical results of laboratory quality. However, emerging technological improvements in gas chromatography (i.e. "Fast" GC) have greatly reduced analysis time from tens of minutes to 1 or 2 minutes. These improvements include redesign of the oven heaters and the vacuum system. By utilizing both of these new technologies in combination with reliable, commercially available mass spectrometers, it is now possible to construct a portable GC-MS capable of being transported by one person, performing analyses in a matter of minutes, and providing reliable analytical results of laboratory quality. Constellation Technology Corporation (Constellation) proposes the incorporation of these technologies into an already existing portable GC-MS produced and sold exclusively by Constellation as a commercial instrument (CT-1128 Portable GC-MS). The existing Constellation field-portable CT-1128 GC-MS unit weighs 75 pounds and provides reliable data of laboratory quality in approximately 17 minutes. The unit is fully capable of detecting a wide variety of volatile and semi-volatile compounds including, but not limited to, CW agents and their surrogates, controlled substances (i.e. illicit drugs), explosives, and industry-related solvents and chemicals. In addition, the CT-1128 GC-MS is fully compatible with SPME syringes. This research will reduce the weight by 25% and the analysis time by 80%. This will make the field portable GC-MS truly useful for performing on-site analyses for various law enforcement agencies, National Guard, first responders, and the military. |

| Title: | Field Chemical Analysis Tool |
| Abstract: | CyTerra Corporation proposes the development of a new Field Chemical Analysis Tool (FCAT) to meet the increasing chemical analysis needs of a sophisticated and mobile US military force. The key Phase I task will be the development of a re-circulating air oven that will provide temperature programming for GC columns in an oven fabricated from commodity items for low cost. Any commercially available GC column up to a 30-meters in length will be accommodated by the proposed oven design. The overall system is expected to consume 750 watts, weigh 35 lbs and occupy 0.15-m3 volume. The anticipated analysis time is less than 90 seconds, and the overall analytical cycle time (i.e., analysis time + cool-down time) will be less than 10 minutes. This novel low thermal mass heating technology provides the basis for a modular approach to field chemical analysis. In Phase I, a Re-Circ heating oven breadboard will be interfaced to existing SPME and MS detection equipment to validate the FCAT design concept. It is anticipated that FCAT will capable of providing laboratory quality chemical analyses in the field. The overall goal of the proposed project is to develop a modular FCAT with configurable sample introduction and detection modules. Taking advantage of years of experience developing field instruments based on fast gas chromatography (GC), CyTerra Corporation proposes the development of a modular FCAT. The anticipated benefits include meeting the field industrial hygiene analysis needs of a mobile military with a sophisticated chemical analysis tool that has configurable interfaces for both sample introduction and detection. The immediate benefits are providing a compact, low power, high performance chemical analyzer in a package suitable to a mobile, fast-deployed military force. A modular instrument design will be the cornerstone of the FCAT such that field operation is simple, field maintenance is infrequent, and set-up time of 15 minutes. Since the low thermal mass oven design is universal for all commercial GC columns and the instrument design is modular, there is the potential to meet many environmental, industrial hygiene and national security chemical analysis needs such as water and air quality, explosives, drugs of abuse or chemical warfare agents. Additionally, since the oven will be fabricated from existing commodity products, the manufacturing cost will be low. The FCAT system controller will be based on existing powerful computer technology making it a versatile standalone tool. |

| Title: | Field Chemical Analysis Tool |
| Abstract: | The purpose of this Phase I effort is to demonstrate the feasibility of using an integrated field portable instrument for field chemical analysis. Currently, no fieldable chemical analysis technology is available that can provide real-time monitoring of hazardous compounds in complex samples such as ambient air. The proposed field-portable integrated SPME sampling, flash GC, miniature mass spectrometer (MMS) will meet this operational need. The performance and capabilities of the MMS instrument will be best in class by providing a level of selectivity that is unmatched by current fieldable mass spectrometers or ion mobility spectrometers. Development of this system will transform traditional sample-to-lab analysis to lab-to-sample analysis. This concept will provide high-end chemical analysis in the field with the potential to save lives and provide a competitive advantage to U.S. armed forces. The performance specifications of this instrument will be demonstrated in Phase I and a full prototype will be developed during Phase II. The instrument that will be developed as part of this Phase I effort will be able to detect chemical warfare agents in the field, but will also find use in Homeland Security, customs monitoring, airport screening, and environmental protection. |

| Abstract: | Implant Sciences Corporation (ISC) proposes to create a Field Portable Flash Collection Flash SPME-Flash GC-IMS unit for the detection of trace chemicals in samples or the environment. The unit will incorporate a cyclonic gas collection nozzle with an integrated high-intensity flash lamp, which will allow for the sampling of volatiles and semi-volatiles from as far as 5 inches away from the surface of interest without significant loss of analytes to the surrounding air. The gases collected by the cyclone nozzle will pass over a standard SPME fiber for a predetermined length of time, after which the fiber will be flash desorbed into a flash GC column. The chemical species exiting the flash GC will be detected by a modified, portable IMS unit developed at ISC which has high resolution, unusually high sensitivity, and has a demonstrated capability of detecting ambient explosive vapors at parts-per-trillion concentration levels. Detection of a wide variety of trace chemicals of interest in the areas of national defense; environmental assessment; water quality management; airline, postal, shipping and general security; and the prevention of, or quick response to, terrorist attacks involving the use of chemical and biological weapons or poisons. |

Syagen has pioneered photoionization mass spectrometry (PI MS) and will use its field-portable PI/QitTof MS as the baseline detector. This system will be modified to meet the requirements of this topic in the following ways: (1) redesigning inlet to accommodate SPME samples, (2) integrating and optimizing a flash GC subassembly, (3) constructing and implementing a dual PI/EI source, (4) developing SPME and direct sampling strategies. The end result of this research will be a feasibility demonstration and definition of a system that will significantly outperform competitive systems with regard to multiple compound detection, sensitivity, speed, and accuracy. Automated field portable detection systems with benchtop performance will have numerous applications, particularly if it combines chemical weapons, drugs, and other illicit chemical detection capabilities. Specific applications include: (1) rapid response alarm monitor for terrorist acts, (2) force protection, (3) preventive medicine, (4) treaty compliance monitoring, (5) general environmental monitoring. |

| Title: | Extending the Life of Biosensors with Dendrimers |
| Abstract: | Echo Technologies, Inc. (ETI) is developing optical biosensors for detection and discrimination of biological warfare agents. The sensors incorporate molecular recognition and fluorescent reporter molecules that are chosen to uniquely detect classes of biological material. Degradation of the fluorescent reporter molecules is one of the important parameters affecting sensor stability and lifetime. Dendrimers are highly branched polymers containing well-defined internal cavities that can therefore function as "host" molecules for one or more "guest" molecules. Preliminary studies suggest that dendrimers could be incorporated to improve sensor properties such as operational or storage lifetime. Echo Technologies proposes to utilize the unique dendrimer characteristics to greatly improve the stability, and operational and storage lifetime of bacterial biosensors. In Phase I the protocols will be developed to incorporate dendrimers of different size and bearing different functional groups into the sensor membrane. The sensors will be tested using aerosolized and waterborne bacterial challenges to demonstrate enhanced performance. In Phase I ETI will team with Michigan Molecular Institute (MMI), a recognized leader in the development and characterization of new dendrimer materials. In Phase II the dendrimer-enhanced biosensors will be more fully characterized and the approach will be extended to biosensors for other Biological Warfare Agents. The proposed use of new dendrimer materials to improve the performance of sensors to detect BWA's will greatly broaden the potential applications for these sensors. The resulting sensors systems will be easier to use, lower cost, and will minimize need for user intervention and logistics requirements. Equally significant is that the proposed approach could be a more generally applicable enabling technology for other optical sensors that contain fluorescent reagents or chromophores. This would include sensors based on antibody/antigen recognition or DNA probes on substrates as diverse as fiber optics to disposable colorimetric "tickets". |

| Title: | Dendrimer Coated Long-Period-Grating (LPG) Biosensor |
| Abstract: | The detection of Biological Warfare agents (BW) is typically conducted using antibody-based techniques. DNA aptomer-based Long Period Grating (LPG) sensors provide the specificity to accurately distinguish the target from potential interference that would produce false positive results. Stability is always a main concern for a sensor-based detection platform. Methods to improve sensor stability have focused on using detergents, salts, protein, and pH. Luna proposes to use dendrimer coating based biosensors to improve stability of BW detectors. This new class of highly branched dendritic macromolecules (dendrimers) has gained attention and is being used to increase the solubility of drugs, produce DNA biosensors, and deliver oligonucleotides to cells. Advantages of dendrimers include structural homogeneity, internal porosity, controllable composition, and multiple homogeneous chain ends. The goal of the proposed program is to enhance the aptomer sensor performance by utilizing dendrimers. Through corporate partnerships and government programs, Luna has successfully demonstrated the detection of protein-protein, DNA-DNA, and DNA-protein interactions with the LPG technology. Improvements in biosensor stability will result in systems that will meet requirements that currently are lacking in BW biosensors. |

| Title: | Enhancing Biosensor Life Using Dendrimers |
| Abstract: | Sensera, Inc. proposes to develop novel biological warfare agent optical sensors based on dendrimers and reporter fluorescent dyes. These generic sensors do not have a biological receptor component and are convenient and cheap to assemble. The long lifetime of the proposed sensors will make them ideal for stand alone detection. During Phase 1, Sensera will develop proof-of-concept bacterial and endospore sensors, which will lay the foundation for a small point detector in Phase 2. During Phase 2, we will also construct actual prototype sensor arrays based on the individual sensors developed in Phase 1. Point detectors consisting of these sensor arrays will monitor both air and water for the presence of bacteria and endospores. Sensera's generic optical sensors will have broad potential markets in homeland defense and environmental monitoring. Due to their low cost and long lifetimes, they will be well suited as continuous monitoring devices and for first responder applications in private and public establishments. |

| Title: | Single Component, Zero Volatile Organic Compound, Chemical Agent Resistant Coating |
| Abstract: | This Small Business Innovative Research Phase 1 Project provides a novel approach to the development of a single pack and zero-VOC Topcoat for the Marine Corps' land based equipment. The technical approach involves a comparison of two polymer concepts. One utilizes a water borne acrylic, the other a Moisture Cured Urethane (MCU). These coatings represent the latest in the state of the art materials to meet the durability, performance and application demands that are envisioned by the military for the foreseeable future. The resin synthesis will show the feasibility of combining cost effective polymer processing concepts with the use of an inorganic pore filing media. These features represent significant advances in the science of high performance chemical agent resistant coatings. The work will show the feasibility of supplementing the barrier properties with a mechanism to detoxify any CWA agent that comes into contact with the coating's filler material. Such a feature compliments the polymer's cross-linking, as a means to mitigate chemical agent transport through the film. These formulations will be tested using a screening protocol that will identify the polymer and processing approach. This innovative approach to the design of high performance industrial coatings will have a profound impact on a global market that exceeds 5 billion dollars in annual revenues. There is a keen interest in materials that will meet and/or exceed the EPA requirements. This scientific advance will serve the environmental needs of the planet without a compromise in performance properties. Isotron Corporation is in a unique position to advance this science into a viable coating system and is prepared to make these materials available to the world. |

| Abstract: | Current DOD chemical agent resistant coating (CARC) topcoats are required to provide protection to the substrate from the harsh natural/service-imposed operational environments. Current coating systems are solvent-borne two components that require accurate metering of the components. PolyComp Technologies proposes to develop novel one component, zero VOC, ambient curing CARC topcoats that can be applied by conventional methods. Based on polyurethane building blocks, the coating will develop novel morphology upon cure, creating a water impermeable surface that is stable towards CB decontamination fluids, as well as satisfying the requirements as drop-in replacement for current polyurethane coatings The novel coating system can be used as dorp-in replacements for current topcoats in USMC as well as assets in other Services. The coating can also be used in commercial chemical resistant applications such as chemical plants, and protection for Homeland Defense equipments |

| Abstract: | Spectrum Coating Laboratories, Inc. proposes to develop a single component, zero VOC topcoat using moisture cured resins and diluents and evaluate the feasibility of these materials for use in chemical agent resistant coatings. Spectrum will synthesize the resins and diluents, conduct a pigment compatibility study and characterize the resultant formulations. The proposed materials and formulations are based on Spectrum's chemical agent resistant topcoats currently in use by the USMC. This approach is expected to reduce the cost of development, and expedite the commercialization of this technology. The coating requires no specialized equipment and allows for rapid change of color in the field. This material can be transitioned into Spectrum's Commercial/Industrial coatings and Maintenance/Architectural coatings to produce single component, zero VOC materials. The result is a series of environmentally friendly coatings for use in a wide variety of applications. These coatings will allow both the federal Government and private industries to meet current and future regulations regarding VOC levels for coating facilities. |

| Title: | Single Component, Zero Volatile Organic Compound, Chemical Agent Resistant Coating |
| Abstract: | Topcoats on military vehicles must satisfy stringent requirements, including durability in harsh environments. Chemical agent resistant (CARC) coatings must also meet a requirement for low permeation of chemical agents into the coating. Topcoats for these applications were originally two-component (2K) solvent-based polyurethanes, and more recently single-component (1K) solvent-based and 2K waterborne polyurethanes. Single-component coatings have a distinct advantage in ease of use, and in avoiding mixing errors during application that can lead to unacceptable performance in the field. CARC coatings must also meet state and local limits on emission of volatile organic compounds (VOCs). The ideal CARC topcoat would be a single-component coating with zero VOCs. Unfortunately, no such coating is now available. TDA Research, Inc. (TDA) proposes to develop such a zero-VOC 1K CARC topcoat. In Phase I TDA will modify the resin system to achieve satisfactory viscosity for application by spray, brush or roller. We will test film formation and coating performance, and assess formulation stability through accelerated testing. We will evaluate coating resistance to solvents, DS2 decontamination solution, and in the CARC test against live agent. In Phase II we will complete development and testing of the coating, including field tests and long-term durability studies. Single-component polyurethane coatings offer simple application and reliable performance. As environmental standards for VOC emissions on coatings tighten with improvements in technology, zero-VOC systems become more desirable. The system we propose to develop will be used not only by the U.S. military, but will also find wide use in architectural, industrial maintenance and transportation coatings where high chemical and weathering resistance is required, and where application with standard equipment and ambient curing is desired. |

| Title: | Integrated System for AAAV Seals |
| Abstract: | Cornerstone Research Group Inc. (CRG) proposes to design and evaluate the components of an integrated seal design. Advanced Amphibious Assault Vehicles (AAAV) have multiple armor and hatch seals. The primary function of these seals is to ensure watertight integrity and EMI protection. The current sealing system design uses two independent seals to simultaneously achieve the necessary level of EMI protection and watertight integrity. Integration these the two seals into one seal would simplify the seal installation and removal procedure while improving critical physical and materials properties. In addition to the materials and geometric design of the integrated seal, other components of the sealing system should be evaluated. By designing and evaluating the system as a whole, rather than improving each component individually, a new system design can exceed the performance of system that was designed as individual components. The integrated seal system that will be designed and evaluated in this program offers improved EMI protection and watertight integrity in one integrated sealing system. The components of this system, which individually and collectively must meet these stringent properties, will exhibit increased electrical conductivity and increased resistance to environmental exposure. The development of materials with these improved properties, could lead to commercialization of the both the seal system as a whole, or to the commercialization of each component independently. |

| Title: | Lightweight, inexpensive, corrosion inhibiting integral and/or multi-component ElectroMagnetic Interference (EMI) and environmental seals for Advanced |
| Abstract: | The Navy seeks a sealing system that provides air and water tight sealing for egress/ingress sites and other hatches and access panels on the Advanced Amphibious Assault Vehicle. This sealing system must also provide corrosion resistance and the maintenance of EMI shielding between sealed interfaces. METSS proposes to develop an elastomer based sealing system that provides durable air and water tightness by virtue of the compressive properties and chemical resistance of the elastomer seal. EMI shielding will result from making the elastomer suitably conductive to electrically bridge the gap being sealed. Corrosion resistance will come from a combination of the chemical resistance and electrical conductivity of the elastomer. METSS will provide the Navy with design information related to constructing and applying the seal to pertinent interfaces, as well as critical information related to the degree of compressibility required to maintain an air- and water-tight seal. The key element in this proposal is the approach taken to induce electrical conductivity. The proposed approach minimizes the amount conductive additive required to support EMI performance such that the chemical and mechanical resilience properties of the seal material are maintained. A wide variety of commercial and industrial applications require corrosion resistant, air- and water-tight seals. Among these applications are boats and land vehicles. Moreover, EMI shielding seals are required in aircraft, computer housings, and vehicle control systems. Almost all machinery can benefit from improved seals. The combination need for EMI shielding in seals and gaskets is growing as the use of electronically controlled equipment accelerates. |

| Abstract: | Triton Systems proposes to develop an integrated multi-functional seal (TIMS) that is lightweight, corrosion resistant, electromagnetic interference (EMI) shielded, chem-bio protective, and environmentally stable for the Advanced Amphibious Assault Vehicle (AAAV). This will be accomplished by combining innovative additives in an elastomeric base (EPDM/Neoprene or like), using Triton's extensive experience in the field of EMI shielding, corrosion protection and nano-technology. For this effort, Triton will adapt its InstaShiel(tm) conductive polymer technology to elastomeric seals for EMI shielding. A metal oxide-conductive polymer (MO-CP) approach will be included for corrosion resistance. Triton's ORMLAS(tm)(Organically Modified Layered Alumino Silicate) nano-technology will be used for chem-bio and barrier protection of the proposed multi-functional seal. In traditional silver and nickel filled silicone gaskets, the metal fillers oxidize over time and demonstrate significant degradation in conducting and EM shielding capabilities. Triton's innovative approach will yield a gasket material that is stable chemically and physically both on the land and sea and offers sustained EM shielding performance. Along with AAAV applications, the proposed technology can be applied to tactical composite shelters. Other opportunities for these EMI shielding gasket materials exist in such applications as shelter systems for military command/control/communications electronics, ground based mobile missile control centers, new and future generation aircraft electronic enclosures, surface and air launched missiles and weapons systems, and ground, sea and air stealth systems. |

| Title: | Multi-component seals for AAAV vehicle |
| Abstract: | Because the AAAV operates within a particularly harsh environment, EMI seals must perform to an exceptional degree of efficiency. The access ports of the AAAV must contain the highest level of EMI protection while demonstrating outstanding sealing and anti-corrosive capabilities. Seal durability and chemical/steam resistance is an important consideration for any material selection in this program. The design concepts Unitech will explore and develop in Phase I and II of this program will continually address these important issues. Corrosion testing and EMI shielding, as well as, seal integrity will be central to all design formats. Although cost and attachment will also be important considerations in Phase I, primary emphases will center on designing the most efficient possible. Phase I efforts will also include a spray system of fabrication that has proved successful in ongoing aerospace program production. This allows layering of materials to tailor the seal's cross-section for optimal performance. Unitech will select several matrix candidates in three material categories noted for their sealing ability and strength. A silicon (RTV) currently approved and used in the F22 program will be specifically examined due to its unique properties demonstrated in 3 year R&D program. It is available commercially and can be post treated to achieve much higher levels of performance than initially advertised. UniShield fill materials (used in commercially available coatings) are already established as some of the highest performance EMI shielding materials ever tested. Listed in the National Security Agency (NSA) databases and currently used by Department of Defense (DOD) for several ongoing applications. We will also investigate several other fill materials that are highly regarded for shielding effectiveness and compatibility. We are confident an exceptional EMI seal system will result in combining these material formulations. It is expected the principle immediate usage for this type technology would be within the Department of Defense. Initial effects would concentrate on making it available for DOD's internal use, with sales to the private sector of secondary importance. Private sector use is anticipated eventually because of the continuing emphases being placed on protection of financial data and propriety industrial trade secrets. Current EMI gasket materials may not provide all the necessary environmental protection in efforts to contain data and protect equipment. |

| Title: | Polymer-Cased Ammunition for Small Arms and Cannon Ammunition |
| Abstract: | Mississippi Polymer Technologies Inc. (MPT) proposes to develop a new generation of polymeric lightweight ammunition for the use by the services. Previous efforts to develop polymer cased ammunition have failed primarily because of problems associated with choice of case materials. During Phase I, MPT will execute a thorough survey of the available polymers and processing techniques, followed by the development of a comprehensive and rational development plan for implementation during Phase II. During Phase I, in addition to its core material science expertise, MPT will utilize a first Finite Element Analysis (FEA) material model of the cartridge case, developed exclusively for MPT, as well as its exclusive access to its proprietary, revolutionary Parmaxr Self Reinforced Polymers. At the conclusion of Phase I effort, MPT will deliver, in addition to the comprehensive ammunition development plan, three (3) prototypes in specified materials for the Navy testing. MPT was incorporated in January, 2000, its first employees started in June, 2000, and MPT moved into its R&D/Pilot Plant facilities in March, 2002. Since that time MPT has executed projects for the Air Force (high performance structural foams), the Army (lightweight ammunition), the NSF (rapid prototyping), and the Navy (lightweight scuttles and hatches for shipboard use). MPT has received two (2) Phase I SBIR contracts, but no Phase II contracts. Accordingly, there has been little basis for commercializing the results of previous SBIR awards. Nonetheless, MPT is making good progress in commercializing its Parmaxr Self-Reinforced Polymer technology. As one result of its R&D, MPT already has entered into a licensing deal regarding the use of Parmaxr SRPs for coating applications, a deal that included substantial up-front payments to MPT. MPT has grown to twenty-five (25) employees, developed a full pilot plant for Parmaxr SRP resins, and is engaged in advanced process development in preparation for full-scale production of Parmaxr SRP resins for commercial sales. Success in the proposed effort will be instrumental in creating commercialization opportunities for Parmaxr SRP resins. With the anticipated availability of sufficient Parmaxr SRP resin production capacity, MPT will be well poised to provide the materials needed for a wide range of commercial, value-added, Parmaxr SRP applications, including as proposed herein. |

| Abstract: | Replacement of gun ammunition cartridge cases made of brass with cases made of an advanced polymer material would alleviate a portion of the weight burden for Marines and air vehicles caused by the need to carry additional gear and high-tech equipment. The replacement of brass with a high-performance plastic will be investigated for the 0.50 caliber system initially, and if successful, the technology may be transferred to 7.62-mm and 5.56-mm ammunition. 0.50 caliber guns are normally used as armament for helicopters, the Marine V-22 air vehicle, some land vehicles, and the standard Marine rifle platoon, which also has smaller caliber guns in their complement of weapons. The use of plastic cases in all of these weapons can provide a significant weight reduction benefit throughout the logistics train and especially to the end user, the Marines. The proposed program will develop and investigate the feasibility of a polymer case design(s) based on structural, mechanical, thermal and interior ballistic analyses and simulations, properties of candidate high-performance polymers, and manufacturing processes required to produce polymer cases. A search and evaluation study will be performed to identify candidate polymers; subsequently, at least one polymer and case design will be selected for Phase II experimental development, evaluation and demonstration. The successful development of plastic-cased ammunition should result in a weight reduction benefit throughout the logistics train and to the Marine and Army end users. Successful implementation into the U.S. military forces should create opportunities for foreign sales and, if the cost is suitable, for commercial sales in the civilian market. |

| Title: | Single Component, Zero Volatile Organic Compound, Chemical Agent Resistant Primer |
| Abstract: | This Small Business Innovative Research Phase 1 Project provides a novel approach to the development of a single pack and zero-VOC primer for the Marine Corps' land based equipment. The technical approach to this primer involves comparison of three polymer concepts (i.e. water borne acrylic, epoxy-ketamine, and moisture cured urethane (MCU). All will utilize VOC exempt solvents. The formulations may incorporate a nanotechnology based filler system. These coatings incorporate state of the art materials to meet the durability, performance and application demands envisioned by the military for the foreseeable future. Functionalized inorganic metal oxide nanoparticles provide a means to enhance the film's barrier properties and to detoxify any CWA agent that comes into contact with the nano-filler material. This feature reduces the demand for cross-linking as a means to mitigate chemical agent transport through the film. The development will consider the synthesis techniques that provide the best overall life cycle cost. These formulations will be tested using a simplified screening protocol that will quickly identify the candidate that has the best prospect for delivering the requisite performance. This innovative approach to the design of high performance industrial coatings will have a profound impact on a global market that exceeds 5 billion dollars in annual revenues. There is a keen interest in materials that will meet and/or exceed the EPA requirements. This scientific advance will serve the environmental needs of the planet without a compromise in performance properties. Isotron Corporation is in a unique position to advance this science into a viable coating system and is prepared to make these materials available to the world. |

| Abstract: | Spectrum Coating Laboratories, Inc. proposes to develop a single component, zero VOC primer using moisture cured resins and diluents and evaluate the feasibility of these materials for use as primers chemical agent resistant coatings systems. Spectrum will synthesize the resins and diluents, conduct a pigment compatibility study and characterize the resultant formulations. The proposed materials and formulations are based on Spectrum's chemical agent resistant primers currently in use by the USMC. This approach is expected to reduce the cost of development, and expedite the commercialization of this technology. The primer requires no specialized equipment and allows for rapid change of color in the field This material can be transitioned into Spectrum's Commercial/Industrial coatings and Maintenance/Architectural coatings to produce single component, zero VOC materials. The result is a series of environmentally friendly coatings for use in a wide variety of applications. These coatings will allow both the federal Government and private industries to meet current and future regulations regarding VOC levels for coating facilities. |

| Title: | Single Component, Zero Volatile Organic Compound, Chemical Agent Resistant Primer |
| Abstract: | Current chemical and corrosion resistant primers for land and amphibious military vehicles are two component solvent or waterborne epoxy coatings. Unfortunately, problems with component mixing and concentration errors with these multi-component paints often compromise coating performance in the field. Therefore, TDA Research, Inc. (TDA) proposes to develop a zero volatile organic compound, waterborne, single component, chemical agent resistant (1K Z-VOC) primer that will eliminate the need for mixing to ensure consistent coating performance and have no impact on air quality. In Phase I TDA will develop the resin system, which achieves satisfactory viscosity for application by spray, brush or roller. We will make clear coats to demonstrate the curing chemistry and we will test film formation and coating performance. In Phase II we complete development and testing of the coating, including field test and long-term durability studies. Single-component coatings offer simple application and reliable performance. They offer ease of use and eliminate the problem of mixing errors during application that can compromise performance in the field. Additionally, as environmental standards for VOC emissions on coating become increasing more stringent, zero-VOC systems become more desirable. The single-component zero-VOC epoxy system we propose to develop will be used not only by the U.S. military, but will also find wide use in architectural, industrial maintenance and transportation coatings where high chemical and weathering resistance is required, and where application with standard equipment and ambient curing is desired. |

| Abstract: | Our main objective will be to develop a single component chemical agent resistant primer which has performance suitable for U.S. Marine Corps (USMC) land based equipment as a drop-in replacement for the current exterior primers while having zero volatile organic compounds (VOCs). UDC will formulate environmentally friendly, chemical agent resistant latex with coupling agents. This material will be compatible with brush and conventional air-atomized spray application methods. Full cured performance of the final primer formulation will be obtainable at ambient room temperature conditions within 2 to 3 days. These primers will be applied on aluminum 2024T3 and steel 1010 substrates for lab testing. The primed substrates will be tested for chemical agent resistance, bond strength, corrosion protection and abrasion resistance. At the end of Phase I, we will provide a report with results and conclusions Phase II plan and cost estimate. This program will provide a single component environmentally friendly chemical agent resistant primer. This technology will be utilized by the architectural, industrial maintenance, and transportation industries for the painting of equipment requiring high chemical and weathering resistance, particularly where ambient curing and the use of standard application equipment is desired. |

| Title: | Improved Propeller De-Icing Systems |
| Abstract: | The de-icing systems for propellers on Navy aircraft can be improved by using electrical sliding fiber contacts and an integrated electrical contact ring assembly. The electrical sliding contacts proposed will be fiber brushes rather than solid monolithic contacts. These contacts have demonstrated the ability to carry large currents at high speed in contaminated environments of oil and dirt. The brush will be designed along with its holder to minimize losses, reduce wear, improve reliability and simplify maintenance. The fiber diameter and length will be determined to meet design goals as well as selecting the fiber material itself and its fabrication process. The slip ring electrical contact assembly will be designed using filament winding techniques to produce an integrated assembly capable of with standing expected temperature gradients, vibration and electrical heating without performance degradation of assembly failure. The best metal surface treatment of the slip rings will be determined to minimize wear and extend life. The feasibility of using an inductively coupled heater, which eliminates the sliding contracts, will be determined including its ability to meet Navy EMI requirements. The Phase I option program will fabricate a sample brush and holder designed in the base program to show feasibility. A sub scale slip ring assembly will also be constructed with one copper slip ring to demonstrate fabrication techniques. A test apparatus will be designed to simulate operating conditions for the complete de-icing systems in preparation for laboratory testing in Phase II. The proposed electrical sliding contacts and slip ring assembly will eliminate assembly failure by using advanced composite design and fabrication techniques. The use of fiber brushes will reduce wear and electrical losses while having the ability to function in adverse environments and oil contaminations. Maintenance will be a minimum with the expected time intervals of much more than 1000 hrs. |

| Title: | Passive Rocket Motor Identification |
| Abstract: | We are proposing to develop unique and innovative Passive Missile Warning signature processing algorithms to meet threat identification needs and optimize IRCM protection for today''s military and civilian aircraft from the early generation AND today''s advanced IR missile threats. Our missile identification algorithm concepts concentrate on real time situational awareness processing of rocket motor radiated emissions, flight profiles kinematic characteristics and aircraft flight computer data to downsize the potential threat list to smaller more manageable lists for optimized tactical IRCM initiation. As the IR threat technologies advance, they also become more difficult to defeat from an IRCM perspective. It would be invaluable to know the type of missile being launched in terms of being able to narrow down the list of countermeasure techniques needed to be implemented to achieve the required aircraft protection levels. Commercialization of the rocket motor identification technology will involve product development, marketing and distribution of the associated MWS upgrades for both military and commercial IRCM applications. Primary candidates for commercialization of our MWS upgrade technology is for commercial aircraft, executive jets and Head of State IRCM applications. |

| Title: | A Spectral-Temporal Sensor for Rocket Motor ID |
| Abstract: | We propose to design a unique sensor that will be capable of providing detection and real-time classification of rocket-propelled and explosive projectile threats from airborne platforms. The approach will take advantage of the simultaneous temporal and spectral signature data already acquired using an existing chromotomographic hyperspectral imaging sensor to identify and exploit relevant spectral-temporal discriminants for real-time rocket motor identification. The new sensor will be designed to unambiguously acquire the spectral-temporal signature of rocket motors for use as the input to current classification algorithms, and be configured for optimal spectral resolution around the phenomenologically important spectral regions identified during the analysis of existing data. The sensor will also be able to passively locate and track the projectile threat throughout its flight from launch inception. It will have no moving parts and a small physical form factor. The design and development of this sensor represents a unique opportunity in spectral-temporal sensing. This effort will benefit the development of compact sensors for exploiting time-evolving spectral signatures of point-like events. This spectral imager will be able to sample the data at rates in excess of 200 spectral signatures per second for un-cued events within a wide field of view. The proposed sensor will be capable of extracting the spectral-temporal signatures for a wide range of dynamic events due to the simple opto-mechanical design and optimization in phenomenologically rich spectral bands. In addition to tactical defense against explosive projectile threats to aircraft, this technology will lead to advancements in strategic missile threat warning, directed energy detection and warning, bomb damage assessment, and automatic location and identification of artillery and small-arms fire. The ability of the new sensor concept to rapidly acquire spectral signatures should provide an unprecedented opportunity to further investigate algorithms for dynamic event classification based on spectral-temporal signatures. In addition, the small physical size of the sensor will demonstrate the possibility of placing an advanced spectral-temporal sensing capability in unconventional vehicles and locations, thus providing tactical missile tail warning for both military and commercial aircraft. It is further anticipated that the new sensor will find utility in bomb damage assessment and situational awareness of battlespace dynamic events. |

| Title: | Ultrapure, Spherical, Monodisperse, Unagglomerated Nanopowders for Infrared Window Materials |
| Abstract: | The objective of this Small Business Innovation Research Phase I project is to develop a novel process for fabricating nanocrystalline ceramic powders for infrared windows. Nano-grained ceramic materials are expected to have sufficient mechanical properties to operate efficiently under the harsh operational environments experienced by infrared window materials on aircraft and missiles. In our proposed work, we will use an innovative method to fabricate nanocrystalline yttria powders for infrared window materials. High quality nano-yttria powder will be synthesized using a chemical precipitation route. The precipitate will undergo a series of agglomerate-reduction steps to yield a high purity, monodisperse, agglomerate-free powder. A very low temperature crystallization process is proposed instead of a conventional solid-state calcination step. This low temperature step is the key to obtaining agglomerate-free powder with final particle size of less than 25 nm. A narrow particle size distribution and high purity are some of the other benefits of the proposed process. Successful completion of Phases I and II of the proposed project will result in an alternate synthesis method for manufacturing nano-powders for infrared windows and other advanced ceramic applications. The market for nano-ceramic powders is projected to reach $156 million by 2003. When this exploding market opportunity is coupled with the defense (industry and government) and commercial market needs for more durable infrared materials, a significant commercial opportunity for these products is expected to develop in the near future. There are three distinct components to our commercialization strategy: (1) fabrication of nano-powders for Government agencies, (2) fabrication of nano-powders for captive use and for sale to other manufacturers, and (3) fabrication of near net shape end products using nano-powders. |

| Abstract: | The proposed program will demonstrate the feasibility of a novel process to synthesize ultrapure, spherical, monodispersed, unagglomerated yttrium oxide nanopowders. These nanopowders will facilitate the fabrication of fully dense infrared windows. Yttrium oxide nanopowders will be made by sonochemical method. The starting materials to be used are pure yttrium nitrate or yttrium chloride or yttrium acetate, suitable solvent and surfactant to keep the particles separated. The effect of various solvents and surfactants will be studied as well as different parameters for sonication such as sonication time and frequency that will be optimized to make monodispersed, unagglomerated nanopowders with diameters less than 25 nanometers. These nanopowders will be characterized for their phase purity, particle size distribution and chemical composition. This process is scalable for larger and more economical quantities of powder.

| Title: | An economical and environmentally acceptable process for high quality nanopowders of Magnesium Fluoride (and related fluorides) |
| Abstract: | Building upon our newly developed chemical synthesis process, which is now being used to produce oxide nanopowders with exceptional particle characteristics, we propose to develop an economical and environmentally acceptable process for producing high quality sinterable nanopowders of fluoride compounds (e.g. MgF2 and CaF2) that can be consolidated into fully dense and transparent infrared transparent windows and domes. The impetus for nanopowders as starting material is that the potential exists for consolidating them into ultrafine grained components with mechanical properties far superior to their coarse grained counterparts, and possibly sapphire, which is the benchmark material. In keeping with this objective, we will demonstrate the feasibility of producing nanopowders of MgF2. As synthesized powders will be characterized by an array of analytical techniques, and test quantities of nanopowders will be provided to the Navy by the end of the Phase I program for further testing. Additionally, the sinterability of the nanopowders will be demonstrated. The synthesis process will be optimized and scaled in Phase II, and nanopowders will be provided to manufacturers of IR windows and domes. We anticipate the nanopowders developed in this program to become one of our growing product lines beginning toward the end of Phase II and into Phase III. MgF2 and related compounds fall into a category of materials generally referred to as specialty materials, as opposed to commodity powders such as silica, alumina, and titania. The number of suppliers as well as users of specialty powders is restricted to a few companies. For a variety of reasons, for certain materials, there is either only one, or in some cases, no US manufacturer. This creates a commercial opportunity for a small US based company such as ours. The market size for specialty materials, even if relatively small, is still in the several hundreds of millions of dollars. |

| Title: | Ultrapure, Spherical, Monodisperse, Unagglomerated Nanopowders for Infrared Window Materials |
| Abstract: | Physical Sciences Inc. (PSI) proposes to fabricate high quality ceramic nanoparticles using an electrostatically controlled spray process. Although the commercial production of nanoparticles has steadily increased over the last several years, the use of nanoparticles for optical ceramic fabrication has been limited. Theoretical expectations have not been met with existing methods due to particle impurities, broad size distributions, and shape anomalies. In the proposed process, cost-effective ultra-high purity reagents and streamlined handling methods will be used to synthesize the materials. The integration of electrostatic control during the formation, transportation, and collection of the particles will be used to assure high quality and efficiency is maintained. At the point of particle formation the development of a multi-element array will increase product throughput to reach suggested manufacturing levels. Successful completion of the Phase 1 program will demonstrate the production of monodisperse, sub-25 nm, high-purity ceramic nanoparticles meeting the need for improved ceramic materials. The total world market for nanoparticulate materials reached $492.5 million in 2000 and is expected to grow at an average annual rate of 12.8% over the next 5 years. Consumers include both commercial and military companies. A partial list of applications for ceramic nanomaterials currently includes uses as abrasives, phosphors, fuel cells, cosmetics, and hard coatings. Success of the proposed technology will allow the nanopowders produced to gain immediate acceptance into existing markets. Additionally, new markets within the areas of structural ceramics and optics will be formed. |

| Title: | Non-Polymer Optical Fiber Coatings |
| Abstract: | The objective of the project is to evaluate and to apply a newly developed nano-particale material (NPM) as an attractive substitute for polymer coatings of optical glass fibers. The NPM is both hermetic and low modulus and possesses several additional marits: immunity to corrosion, good adhesion to the adjacent materials,hydrophobicity, practically infinite lifetime, "self-healing" ability, etc. The NPM application will enable one to reduce considerably the outer diameter of the coated fiber and to make the fiber highly mecanically reliable, environmentally duarable and extremely cost effective. The preliminary test data are very encouraging. The new coating design will be very attractive to both leading (large) optical fiber manufacturers, as well as to small companies. No significant changes in the existing drawing equipment are necessary. The application of the proposed design will result in higher quality and lower cost of the photonics products employing silica opticalc fibers. |

| Title: | Dual Hybrid Glass Non-Polymer Coatings for Optical Fibers |
| Abstract: | Hybrid Glass Technologies Inc.(HGT) proposes to develop novel, hybrid glass based protective coatings for optical fibers. These dual layer coatings not swellable by water or organic solvents will possess the hermetic properties that eliminate water corrosion of the fiber, provide mechanical protection, significantly reduce the diameter of the coated fiber and substantially improve the fiber lifetime and reliability performance. The hybrid glass formulation is either heat or UV-curable and will be fully compatible with current coating techniques and systems. Due to the hybrid material viscoelastic properties and its ability to form strong chemical bonds with the glass surface, the novel coatings will eliminate the problems with fiber terminations and splicing and reduce microbending losses of the fiber. The coating components will be synthesized by a well controlled, cost effective, environmentally benign modified sol-gel process. The formulations for the hybrid glass coatings will be low viscosity, solvent free clear liquids, stabilized to achieve a long shelf life. They will be able to cure rapidly and therefore be applied on-line during fiber drawing. The planned process will produce a class of inorganic-organic hybrid glass formulations yielding superadherent, hermetic coatings with tailored hardness and of excellent mechanical, chemical and environmental stability. While the most immediate applications of the non-polymer hybrid coatings being developed under this phase I SBIR project, are targeted to optical fibers in adverse military environment, all of today's commercial telecom fibers as well as photonic components can potentially be impacted by the proposed HGT effort. More than 99% of all current optical fibers employ UV-cured polymer coatings that make them vulnerable to significant strength reduction and eventual failure in the field. This is clearly a dual use materials technology that is being proposed. Major fiber manufacturers such as Corning Incorporated, OFS-Fitel and Alcatel are potential licensees of a next generation optical fiber coatings. In addition, low cost hermetic packaging technology for electronic and optoelectronic circuity might also benefit from this R&D effort. Emerging civilian markets for next generation optical fibers will include a diversity of applications including fiber to home(FTTH), intelligent infrastracture, environmental monitoring, biomedical imaging, automative sensing and smart packaging. |

| Abstract: | Fiber-optic technology is finding increasing importance in a wide range of applications within the navy, such as in structural health monitoring of warships, high-resolution image transmission, guided weapons, gyros and optical motherboards for computers. Optical fibers are typically enclosed in a hermetic layer over the cladding that protects the core and the cladding from mechanical, thermal and chemical damage. Various polymeric materials are applied on the surface of the glass fiber to protect it from the harsh environment. Polymers, however, absorb moisture; as a result, long-term mechanical reliability of polymer-coated fibers might be not as high as necessary. An alternative effective coating material that possesses the merits of organic polymers and carbon/metallic hermetic coating, without the drawbacks of these materials, is proposed in this phase I proposal. Apart from use in the navy for fabrication of high-security, high-performance communication networks, the optical fibers developed will also find use in a plethora of civilian applications that involve optical communication. |

| Title: | Air Antisubmarine Warfare Environmental Characterization Using Existing Tactical Sensors |
| Abstract: | Air ASW search rates are critically dependent upon source-receiver separations, which are in turn driven by acoustic propagation and noise characteristics. To optimize the search rate, an accurate environmental assessment must be performed. The current techniques of using monostatic reverberation to invert for scattering strength and geo-acoustic parameters is fundamentally limited by the fact that all reverberant energy must propagate from the source to the bottom and then back to the receiver. A technique is proposed to simultaneously invert monostatic reverberation and direct blast propagation recordings using existing sources and sonobuoys. A physically consistent sediment model is used to permit extrapolation of acoustic predictions in frequency or source/receiver depths. ORINCON proposes to couple this environmental characterization with the development of a search-update algorithm to permit the optimization of air ASW search rates via the incorporation of tactical acoustic data taken while conducting the search, rather than during a preflight environmental characterization. In Phase I of this research, the self-consistent inversion approach, using tactical data and the search-update rule set, will be developed. These will be incorporated into the Geo-Acoustic Inversion Toolbox (GAIT) program of SPAWAR PMW-155 during Phase II and demonstrated at-sea, in real time, using ex |
