Abstract:Each year, over 115,000 patients in the US need to have their diseased heart valves replaced with artificial devices. Although bioprosthetic valves are considered ideal, they wear out in about 15 years and are thus used primarily in the elderly who are notexpected to outlive the valve. Younger… more

Abstract:The now rapidly developing field of plastic materials based on renewable resources (bioplastics) provides tremendous opportunities to sustain and enhance the domestic plastics industries, the fourth largest manufacturing sector of the American economy. In addition, bioplastic materials are derived… more
Abstract:Monopropellants are readily ignited or decomposed over a bed of solid catalyst. A serious limitation of existing catalysts in the ignition of advanced monopropellants is limited thermal stability. The recent emphasis on improved performance of monopropellant technology (e.g., with AF M315E and… more
Abstract:Cold spray has many benefits compared to conventional thermal spray including lower deposition temperatures, higher bond strengths, less substrate preparation and better control of coating composition, phase structure, and oxide contamination. In cold spray, particles are accelerated by an expanding… more
Abstract:LIDAR (LIght Detection And Ranging) systems have proven their value in the remote measurement of spatially resolved atmospheric wind velocities in a number of applications, including the detection of clear-air turbulence, wind shear, aircraft wake vortices, and microbursts. The capacity of coherent… more

Abstract:This Small Business Innovation Research Phase II project is targeted at the development of a novel, low-cost continuous method for the production of ionic liquids. Ionic liquids are a class of industrial chemicals with broad applications in energy, pharmaceutical, biomass and solar fields. Ionic… more
Abstract:ABSTRACT: This SBIR Phase I project is targeted at the development of a novel ultracapacitor using ionic liquid electrolytes. Commercially available ultracapacitors exhibit high power density, in excess of 6000 Wh/kg, but relatively low energy density of under 10 Wh/kg. Boulder Ionics proposes to… more
Abstract:Thermal batteries serve as ultra-reliable electrical power sources in guided munitions, missile systems, and some emergency escape systems. These batteries have very long storage lifetimes, in excess of 20 years, due to an electrolyte that is solid and non-conductive to ions at ambient temperatures.… more
Abstract:This Small Business Innovation Research (SBIR) Phase II project focuses on coupling sound to the human ear for communications devices (MP3, Bluetooth, hearing aids, headsets, earbuds) with unprecedented comfort, safety and audio quality. A chip-like device, the diaphonic valve, for harvesting energy… more
Abstract:DESCRIPTION (provided by applicant): This study focuses on the production and testing of prototypes of a new inflatable technology for coupling sound into the human ear, for hearing aids. The technology has the potential to dramatically reduce the cost, and increase the safety and convenience of… more
Abstract:Cooling water systems in thermal power plants are notoriously difficult to maintain because they provide the ideal, warm environments for the growth of algae and bacteria. This biofouling can lead to corrosion and cracking of cooling pipes in heat exchangers. Conventionally, disinfection chemicals… more
Abstract:Five years ago, Congress set a goal of 500 million gallons of cellulosic ethanol produced in 2012. Although progress has been made, EPA has drastically reduced its 2012 U.S. production projection to only 8.65 million gallons. This huge shortfall is due to many factors, including high capital costs… more
Abstract:DESCRIPTION (provided by applicant): The overall goal of this project is to develop and commercialize a simple cell counter for routine enumeration of CD4 cells for management of HIV-infected individuals. HIV-1 mediated CD4 cell destruction is the centralimmunologic feature of HIV-1 infection. Thus… more
Abstract:DESCRIPTION (provided by applicant): Completion of the HGP (human genome program) has opened the 'Genomic Era' in biomedical research and enables functional genomics analysis of various gene elements. The long-term goal of the ENCODE Project is to identifyand functionally characterize all… more
Abstract:To optimally address this HSL for Army expeditionary shelters, we propose two novel innovations: (1) a flat-panel"Passively-Tracking"Solar Concentrator, leveraging our existing Holographic Solar Concentrator technology, to achieve high (>400x) concentration ratios with an ultra-wide… 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.
