Ceramic matrix composites (CMCs) are being targeted for many military and commercial applications due to their light weight and high temperature stability. Their deployment is hampered by limited environmental durability. The Navy, under the JSF program, is evaluating a high performance CMC for an exhaust nozzle component. The CMC suffers from environmental degradation, primarily due to hot cor ...

Critical gears and engine bearings in our newest vertical thrust aircraft must operate with absolute reliability under high loads, high heat, corrosive salt air and intervals without any lubricant whatever. Current materials and coatings that meet some of these conditions fail when subjected to the others. Now a breakthrough in surface engineering technology can precisely control deposition of c ...

This Small Business Innovative Research Phase I project is to develop a broad band detection system for air toxicity. Our overall objective is to show that honey bee orientation and locomotor behaviors can be used as reliable and measurable indicators of certain airborne toxicants. Locomotor sufficiency and directional orientation are behaviors that should unambiguously indicate toxicant exposu ...

This project's objective is to develop honey bee colonies as broad band, wide area detectors of airborne toxicants. Phase I focused on identifying behavioral endpoints that assess the locomotor and task solving performance of 'exposed' foragers returning to the hive. Preliminary results indicate that speed of maze navigation and recognition of 'exposed' foragers by entrance guard bees hold prom ...

Ventilation systems are extremely venerable to incidental and malicious attacks by terrorists and saboteurs. During attacks by chemical and biological weapons, personnel in temporary and permanent shelters are dependent on a constant supply of clean air. Consequently, the main objective of the proposed work is to develop a microwave low-temperature catalytic oxidation system that will effectively ...

This project leads the efforts of advance heat exchanger technology through the integration and convergence of the best emerging methods and materials for increased heat transfer and efficiency. Achieving high efficiency, beyond the present art, involves an in-depth analysis of present heat exchanger designs, by gaining an understanding of application specific demands within mobile equipment such ...

This project develops a conjugate vaccine against Shigella flexneri 2a utilizing cGMP-compatible manufacturing processes. The antigenic component of the vaccine is deacylated-polysaccharide from the bacterial LPS that has an average of one O-antigen repeat unit per polysaccharide molecule. The polysaccharide is deacylated by a biological process, and has a core structure with intact phophosphory ...

There is need for a commercial vaccine against shigellosis because all groups of pathogenic Shigella have acquired resistance to antibiotics. Shigella conjugate vaccines have proven safe and protective in previous clinical trials, but obstacles associated with large-scale manufacturing of these subunit vaccines have apparently hindered commercial development. The present project uses a new and s ...

We propose the development of high quality HgCdTe-based materials and high performance two-color detector arrays operating in the very-long wavelength infrared (VLWIR) spectral region. The fabrication of large format, high sensitivity focal plane arrays sensing in the VLWIR is highly desirable for various applications complementing Missile Defense, Army, Navy, and Air Force capabilities. They will ...

High-performance detectors sensing in the long wavelength and very long wavelength infrared spectral ranges are desirable for various applications supporting Air Force and Missile Defense capabilities. Limited types of detectors and arrays are currently available for the detection of infrared radiation with wavelengths longer than 15 microns, and most are based on low quantum efficiency extrinsic ...
