Abstract:Todays thermoelectric cooling materials exhibit a peak performance, termed ZT, of about 1.0. Recent development in the theory of quantum-well superlattices suggest that ZTs of up to 9 are possible. Work is ongoing to synthesize superlattices using techniques such as molecular beam epitaxy,… more
Abstract:Bismuth rich BiSb alloys exhibit the best n-type thermoelectric properties known. However, these properties are realized only in single crystals which are difficult to machine because they tend to cleave. Also, the anisotropic nature of BiSb requires that that the device current be passed across… more
Abstract:Improved methods for identification of new longitudinal patterns of alcohol-related symptoms,administrative strategies, as well as medical and psychiatric conditions which effectively predict patientoutcome status in existing databases would be invaluable to local, county, state, and national… more
Abstract:The objective of this Phase I investigation is to utilize proven vortex entrainment and circulation technology to demonstrate the feasibility of a high flowrate feed system capable of safely delivering energetic materials to molten salt destruction reactors. The use of vortex entrainment technology… more
Abstract:We will develop a new low cost, data driven manufacturing technique for direct printing of micro-optical elements onto optical substrates and devices. We will apply our ink-jet printing technology to form and place microscopic droplets of optical materials, such as UV-cured resins and sol-gel… more
Abstract:This proposal concerns the development of a new method for etching, contouring, and cavitating teeth. The method consists of microdispensing a photoabsorptive dye onto the surface of tooth then focusing a laser beam on the dye spot, which is 75-200mum in diameter. By the appropriate choice of… more
Abstract:Software will be developed to commercialize the newly invented sinusoidal voltammetry. This requiredesign, coding and validation of a software system that can drive a potentiostat at a fundamental frtime operate in the frequency domain to resolve the amplitudes and phase angles of the relevant… more
Abstract:COMPLETION OF THIS PROJECT WILL PROVIDE A MULTIMEDIA SOFTWARE TUTORIAL INTRODUCTION TO THE PHYSICS AND ENGINEERING CONCEPTS OF SUPERCONDUCTING MAGNETS FOR HIGH ENERGY PHYSICS ACCELERATORS. THE PRESENTATION OF THE MATERIAL WILL MAKE FULL USE OF THE LATEST COMPUTER TECHNOLOGY FOR HYPERTEXT,… more
Abstract:THE UNITED STATES COAST GUARD (USCG) HAS LONG BEEN INTERESTED IN THE MITIGATION OF HAZARDS TO LIFE SAFTEY FROM FIRE ONBOARD SHIPS. THE DEVELOPMENT OF SUPERIOR FIRE RESISTANT COATINGS FOR GLASS-REINFORCED POLYMERIC (GRP) COMPOSITES, WHICH MAY BE USED AS BULKHEADS, DECKS AND INTERIORWALLS, IS ONE WAY… more
Abstract:We propose to develop new techniques for specimen preparation for the assessment of chromosome breakage in human cells by fluorescent in situ hybridization. The methods are applicable to automated image analysis at high resolution so that very low levels of chromosome damage will be detectable. We… more
Abstract:Marine simulators have historically used image generators designed for flight simulation. These systems do not provide the special effects required for marine simulation. The current generation of high-performance, low-cost graphics workstations, combined with commercial rendering software, provide… more
There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
