78072S III-V nitride-based, high brightness, UV and visible light emitting diodes (LEDs) are of a great interest for general illumination, but the low light output efficiencies of current high brightness LEDs are still inadequate. A key material issue preventing the achievement of higher light output efficiency in LEDs is the poor crystalline quality of the nitride epitaxial layers that result fr ...

Several of the present methods of decontamination of biothreat agents, especially the spore-forming Bacillus anthracis (anthrax) rely on steam or disinfection with highly corrosive agents. While these methods are effective, such procedures are impractical when the contaminated materials and/or equipment are mail, paper documents, delicate instruments, or complex machinery such as mail sorting equ ...

Liquid fuel injection into heated and vitiated cross flows, at elevated pressures, will be investigated experimentally and through numerical simulations. Experimental efforts will include advanced optical measurements of liquid spray parameters at positions close to the injection site, as well as downstream. Liquid spray modeling will include first-principles, physics-bsaed modeling of liquid brea ...

DESCRIPTION (provided by applicant): Neuropsychiatric and neurodegenerative disorders such as schizophrenia, Alzheimer's disease, and depression are genetically complex diseases with multiple contributing genes. There is an urgent need for innovative technologies to study the multi-gene etiology of these disorders for early diagnosis, prevention, and treatment. Advances in the Genomas PhysioGenomi ...

DESCRIPTION (PROVIDED BY APPLICANT): This Phase I SBIR Program will develop genetic diagnostic products to improve the safety of atypical antipsychotics (e.g. olanzapine) for treating psychiatric disorders, including schizophrenia. Atypical antipsychotics are prescribed as long-term treatments for an increasing number of indications even to adolescent's patients. In up to 50% of patients, these hi ...

This phase II SBIR proposal is aimed at development of low-power field emission display devices. Flat panel display market is one of the fastest growing technology sectors. Despite its fundamental strengths, the role of field emission (FE) technology in the market place is marginal at best. This is in part due to the inability to operate efficiently at low power. Low-power operation requires a hig ...

This phase I SBIR proposal addresses development of a generalized benign, high throughput, low-cost silicon die thinning etch tool. Thinning of Si dies is required in many advanced 3-D packaging, rad-hard and flexible-circuit electronics. For example, using hyper-thin (~ 10-25 m) Si memory dies, a stack of 500 MCMs/inch can be formed to provide ~ 200 gigabits/cu. in. density using 64 mbits Si m ...

Conventional watering uses hose or boom irrigation systems to apply excess water to ensure complete coverage of the entire crop to the point of full saturation of the root medium. This method is costly in terms of water and nutrients. Water falls outside the area of the pots and is lost to the environment. Excess water may leach up to 75% of the fertilizer from potted plants. It may be necessary t ...

The objective of this proposal is to demonstrate a well characterized, production-friendly, bonding technique with predictable and measurable bond quality for joining zirconium to tantalum for use in lethal air-to-air warheads. Lethal warheads or kinetic energy penetrators for land-based and air-based use have been successfully implemented in military applications for almost two decades and are ...

High energy optical components, such as beam splitters, are specified and designed to meet increasingly tight system level alignment budgets while subjected to severe environmental loads. These loads include shock and vibration loads generated by a number of sources, such as those environments present for the Airborne Laser. Kinematic mounts supporting these components are a desirable design fea ...
