The latter is the core technology behind an envisioned Phase III handheld chemical standoff sensor for detection of chemical warfare (CW)… more
Abstract:The Army is interested in developing conductive polymer materials that have a very high conductivity, but are also processable into a range of particle shapes and sizes. These anisotropic particles will be tuned to provide obscuration properties in broad portions of the electromagnetic spectrum. … more
Abstract:There is a need to find more efficient methods for producing high-density, liquid, tactical fuels for use in missile propulsion or as components to improve key performance characteristics of currently available jet and diesel fuels. Generation of such fuels from renewable sources including waste… more

The proposed work follows from… more
Abstract:PM & AM Research and Texas A & M University will develop an innovative non-invasive technique to meet the current DoD need for simultaneous acquisition of the velocity and acceleration fields of both a fluid and solid undergoing a fully-coupled fluid-structure interaction. Modern composite… more
Abstract:With the notable exception of glucose, most metabolic biomarkers cannot be accurately, and practically measured over long periods, in vivo and in real-time. A primary reason is stable, selective enzymes suitable for biosensors are not available. Biosensors could revolutionize acute and long-term… more
Abstract:PocketSonics Inc. proposes to develop an ultra-portable, highly integrated ultrasound device optimized for use by minimally trained users assessing and guiding resuscitation of combat casualties at the initial point-of-care. Current portable systems have limited battery life, cumbersome cables, and… more

Abstract:Reductions and reallocations of telemetry wireless bandwidth have prompted the need for DoD agencies to adapt to operation in more restricted and less desirable frequency spectrum. Telemetering systems must evolve to address these frequency allocation changes, while retaining operational… more
Abstract:A notable failure mechanism in thermal barrier coatings (TBCs) is the attack by calcium-magnesium-alumino silicate (CMAS) deposits resulting from the ingestion of siliceous minerals with the intake of air. Existing TBC systems such as yittria partially stabilized zirconia (YSZ) are highly… 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.
