This aerogel-polyurea based composite coating system will possess a thermal conductivity of less than 25 mW/m-K at 205oC, have… more
Abstract:In this Phase I SBIR proposal Physical Sciences Inc (PSI) outlines the development a solid-state emitter package to replace the propellant based candle of the M278 Infrared flare. Propellant combustion in the current candle technology is unsteady, resulting in variations in the illumination… more
Abstract:Measurement of the ratio of the concentrations of the stable isotopologues of CO2 in the atmosphere can provide new understanding of the dynamics of CO2 exchange between the atmosphere and terrestrial ecosystems. On the local scale, such measurements enable the study of the net ecosystem exchange… more
Abstract:Precise measurements of CO2 are important to carbon cycle studies and global warming research, especially with respect to the characterization of sources and sinks. New, miniaturized and low cost instrumentation is required to make measurements of the vertical concentration profiles of CO2 from… more
Abstract:Nickel metal hydride (NiMH) batteries are used in hybrid electric vehicles (HEV). In order to increase automobile market share, NiMH costs need to decrease by providing a higher energy density and longer lifetimes. This project will develop a non-fracturing, low-cost, TiMn2 metal hydride negative… more
Abstract:In order to meet the objectives of the U.S. contribution toward diagnostics on the ITER fusion reactor, which is being built by an international team, the CO2 laser frequency doubler must achieve a significantly higher conversion efficiency, in order to enable very low noise operation of the sensing… more
Abstract:DESCRIPTION (provided by applicant): Fine needle aspiration biopsy (FNAB) is a rapid and cost-effective procedure that uses a syringe to sample fluid from a cyst or remove clusters of cells from a solid mass for diagnostic purposes. The effectiveness of FN
AB is operator-dependent and the diagnostic… more
Abstract:DESCRIPTION (provided by applicant): This proposal addresses a need for an improved technology for both diagnosis and treatment of patients with cystic neoplasms of the pancreas. Currently, endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) tech

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.
