Abstract:Metal additives to explosive formulations are commonly used in high energy military and commercial explosives, solid fuel rocket propellants and military and commercial pyrotechnics. Aluminum metal is a stable low cost fuel that is typically used in the form of powder or flake. In high energy… more
Abstract:Photorefractive materials promise to enable dynamic holography and erasable high density data storage for future information technologies. This project will develop and demonstrate a holographic data storage technology using novel photorefractive polymers with electro-optic (EO) coefficients and… more
Abstract:Hydrazine is a highly toxic compound that is widely used as a rocket fuel in U.S. space programs. Since very low concentrations of hydrazine are considered hazardous, there is need for sensors that are robust, cheap, sensitive and selective. Sigma Labs proposes a low cost manufacturing method for… more
Abstract:A multichannel array detector for mass spectroscopy with a novel configuration is proposed. A triplconversion approach is used whereby incident ions are used to generate secondary electrons which strwhich produces optical photons. The photons are detected with an imaging charge coupled device… more
Abstract:The specific aim of this project is to design, develop and test a comprehensive data system regardisubstances in household consumer products. It will include a file on hazardous substances in consumethe toxicological effects of these substances; a file on alternatives to the products which… more
Abstract:We will isolate a temperature sensitive mutant of streptavidin that will bind biotin at 4C but notbe accomplished by chemical mutagenesis to saturate the streptavidin gene with mutations. A scheme ftemperature sensitive mutant will be employed. The library of mutants and the enriched library… more
Abstract:WYKO proposes to demonstrate the feasibility of an optical contouring system that will quickly measure the shape of both the resting and loaded foot to allow automated manufacture of therapeutic footwear directly from the data provided in an open architecture format. This bypassess the steps of… more
Abstract:Solid Free Forming of monolith and uniform discrete reinforced materials has been demonstrated by fused deposition of heavily loaded slurries. In this program we will extend the fused deposition process to functional gradient material. The composition of material deposited will be controlled by the… more
Abstract:We will develop and validate a new assay system to replace existing immunocytochemicalassays for detecting occult micrometastases in bone marrow of patients with primary breast cancer.This assay would offer simplicity, low cost, and a quantitative end point. The assay is based on aninnovative… more
Abstract:REGENERATORS THERMOFLUID CRYOREFRIGERATORS THE NEW TYPE OF REGENERATORS PROPOSED OFFERS FOR 10 K CRYOCOOLERS THE PROSPECT OF REDUCTIONS OF 100'S OF WATTS OF POWER AND KILOGRAMS OF WEIGHT PER WATT OF REFRIGERATION, AND EXTENSION OF OPERATING LIFE BY 10,000'S OF HOURS. PHASE 1 WILL DEFINE THE MODELING… more
Abstract:The goal of the proposed research effort is to develop a cost-effective system capable of measuring leakage into gas masks being worn by Navy personnel. The ability to measure gas mask leak rates will greatly enhance chemical warfare training effectiveness, thereby increasing the level of protection… more
Abstract:RESEARCHERS ARE USING THE PIONEERING OF THE PAST 25 YEARS AND COMBINING THE USE OF COMPUTERS AND A NEW PIEZOELECTRIC MATERIAL TO CONCEIVE AN ARRAY OF 14,000 NODES THAT CAN PRODUCE THE DIMPLE FOR TACTILE SENSATION. THIS ALSO ANSWERS THE NEED FOR DESCRIPTIVE VIDEO SERVICE (DVS) TO PERSONS WITH VISUAL… more
Abstract:KINETIC ENERGY PENETRATORS MADE OF DU ALLOYS PERFORM BETTER THAN THE TUNGSTEN HEAVY ALLOYS (WHA). THE IMPROVED PERFORMANCE IN DU ALLOY PENETRATORS IS ATTRIBUTABLE TO FAILURE BY ADIABATIC SHEAR BANDING WHICH HELPS THE PROJECTILE MAINTAIN A SELF-SHARPENED CHISELED NOSE THERBY PENETRATING FURTHER THAN… 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.
