Abstract:ABSTRACT: Modern military space systems use high specific impulse (Isp) propulsion systems to provide efficient station keeping and large delta-V orbital maneuvers. A multi-mode propulsion system utilizes a single propellant such as AF-M315E to provide high thrust as well as a 1000-4000 s Isp. By… more
Abstract:Sample return missions, by nature, require high levels of spacecraft autonomy. Developments in hardware avionics have led to more capable real-time onboard computing platforms, which allow for the implementation of more sophisticated algorithms. A real-time convex optimizer named COARSE (Convex… more
Abstract:If the energy resolution of electron energy loss spectroscopy (EELS) carried out in a scanning transmission electron microscope (STEM), with an atom-sized electron probe, could be improved to 10 meV or better, a new way of studying materials at the atomic scale, by recording and analyzing their… more
Abstract:This Small Business Innovation Research (SBIR) Phase II project is focused on the reuse of waste glass to generate high-value replacements for traditional masonry products. Masonry manufacturers cannot meet the construction industry's needs with their status quo product and are therefore losing… more
Abstract:The current method for monitoring hexavalent chromium in groundwater at environmental legacy sites is labor intensive, costly and does not allow for continuous in situ monitoring. The research project is developing an affordable, sensitive, durable and low-maintenance in situ sensor capable of… more
Abstract:The Navy needs a metal cutting system for submarine and aircraft carrier hull disposal. We propose to develop a Hull Cutting Mill (HCM) to meet Navy needs.

Abstract:ABSTRACT: We propose to develop for the Air Force a high-efficiency Waste Heat Removal System (WHRS) that removes large amounts of waste heat from aircraft with negligible impacts on signature and aerodynamic performance. Our WHRS absorbs heat from aircraft thermal loads, including a Thermal… more
Abstract:This Small Business Innovation Research Phase I project seeks to greatly improve the light output of white-light light-emitting diodes (LEDs) using fluorescent nanoparticles or quantum dots (QDs) made from silicon. The most efficient and economical design for a contemporary white LED is based on a… more
Abstract:For soldiers in the field, there are limited opportunities for normal hygiene. Showers/bathing facilities are limited, as is the ability to launder uniforms, underwear and bedding. A lack of clean water can make even basic hygiene difficult-- in addition to the obvious problem of unsanitary drinking… 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.
