Abstract:There currently does not exist a high resolution, high dynamic range, quantum limited detector of radiated emissions in the ultraviolet, visible, or near-infrared spectral regions. A proposal for a detailed design of an Avalanche CCD Imager and its supporting camera system is presented. The design… more
Abstract:AN ANALYTICAL INSTRUMENT CAPABLE OF SELECTING COAL BLENDS THAT MEET FUEL AND SULFUR DIOXIDE REQUIREMENTS WITH MINIMUM POST COMBUSTION EMISSIONS WILL BE ASSEMBLED AND DEMONSTRATED IN PHASE I. THE ANALYZER WILL USE NUCLEAR MAGNETIC RESONANCE TO MEASURE THE CARBON, HYDROGEN, AND THE MOISTURE CONTENTS… more
Abstract:THE FEASIBILITY OF A SIMPLE ATMOSPHERIC CARBON DIOXIDE (CO2) SENSOR FOR OCEANOGRAPHIC DEPLOYMENT WILL BE EXPLORED IN THIS PHASE I PROJECT. THREE BASIC STEPS ARE REQUIRED FOR SENSOR OPERATION: MEMBRANE EQUILIBRATION OF GASEOUS AND AQUEOUS CO2, CHEMICAL AMPLIFICATION OF THE CONCENTRATION OF THE… more
Abstract:The proposed Fiber-Optic Chemiluminescent Biosensor concept forms the basis for the development of a new class of light weight, small, low power, inexpensive robust, accurate and extremely sensitive sensors which can be applied to various analytical requirements within the aerospace biomedical,… more
Abstract:This project is designed to explore the feasibility of the development of a small, compact(lunchbox size), stand-alone and rapid infant hearing screening instrument that utilizes a two levelscreening technique. The first level of screening used an automated otacoustic emissions test for a veryquick… more
Abstract:Groundwater remediation at military and civilian sites is a growing need throughout the U.S. For contaminant streams containing JP4 constituents and chlorinated organics, for example, in-situ bioremediation can sometimes require augmentation, such as that which would be provided by a catalytic… more
Abstract:Several objectives in this proposal include systematic study of innovative ways and means to improve survivability and safety of airborne platforms (C-130, C-17, Helicopter), flight crew, paratroops, cargo and equipment. High altitude deployment and glide operations, and airborne snatch and recovery… more
Abstract:THE PRINCIPAL OBJECTIVE OF THIS PROJECT IS TO DETERMINE THE TECHNICAL FEASIBILITY OF DEVELOPING A DRUG-RELEASING IMPLANTFOR TREATMENT OF ALCOHOLISM. SPECIFIC AIMS DURING PHASE I ARE TO DEVELOP PROTOTYPE IMPLANTS THAT RELEASE DISULFIRAM METABOLITES AND TO TEST THE EFFICACY OF THESE IMPLANTS IN RATS.… more
Abstract:CHEMICAL PROCESS INDUSTRY SEPARATIONS CONSUME AS MUCH AS 4.4 QUADS OF ENERGY ANNUALLY IN THE UNITED STATES. MANY OF THESE SEPARATIONS INVOLVE REMOVING ORGANIC COMPOUNDS FROM AQUEOUS PROCESS STREAMS. SEVERAL TYPES OF CONVENTIONAL UNIT OPERATIONS ARE USED TO REMOVE OR DESTROY ORGANICS IN AQUEOUS… more
Abstract:LARGE QUANTITIES OF VOLATILE ORGANIC CONTAMINANTS (VOCS) ARE DISCHARGED FROM INDUSTRIAL PROCESSES INTO THE ATMOSPHERE. THE RECOVERY OF VOCS OFFERS BOTH ENVIRONMENTAL AND ECONOMIC BENEFITS: EACH KILOGRAM OF ORGANIC CONTAMINANTS RECOVERED AND REUSED REPRESENTS ONE LESS KILOGRAM THAT MUST BE… more
Abstract:ABOUT 25 PERCENT OF U.S. NATURAL GAS RESERVES ARE RENDERED UNUSABLE BY HYDROGEN SULFIDE (H2S) CONTAMINATION; IF THIS SOUR GAS WERE TREATED, OR "SWEETENED", THE RESERVES COULD PROVIDE ENOUGH NATURAL GAS TO MEET THE ANNUAL NATIONAL DEMAND FOR 6 YEARS. CURRENT SOUR-GAS SWEETENING PROCESSES PRODUCE… more
Abstract:RECENT INVESTIGATIONS INDICATE THAT DIPEPTIDES MAY HAVE SEVERAL ADVANTAGES OVER FREE AMINO ACIDS AS THE NITROGEN SOURCE IN THERAPEUTIC ENTERAL AND PARENTERAL NUTRITION. IF THE USE OF SYNTHETIC DIPEPTIDES IS TO BE INVESTITAGED COMPLETELY AND ULTIMATELY INCORPORATED INTO MEDICAL PRACTICE, IT IS… more
Abstract:THE CONTROL OF VOLATILE ORGANIC CONTAMINANT (VOC) EMISSIONS FROM INDUSTRIAL PROCESSES AND FUEL SOURCES IS AN IMPORTANT ENVIRONMENTAL PROBLEM. STRINGENT REGULATIONS HAVE BEEN ENACTED THAT WILL LIMIT SUCH EMISSIONS, HEIGHTENING THE NEED FOR SMALL, SIMPLE UNITS THAT CAN RECOVER VOCS AND RETURN THEM AS… more
Abstract:This proposal is directed to the preparation of high-surface-area (HSA) activated-carbon fibers that are suitable for the Army's lightweight chemical-protective combat uniforms. The overall goal of the proposed program is to develop a domestic source of activated-carbon fibers having surface areas… more
Abstract:ADAPTATION OF STATE-OF-THE-ART GIGAHERTZ WAFER PROBE TECHNOLOGY (WPT) FOR USE IN DESIGN, TROUBLESHOOTING, AND PRODUCTION OF MULTICHIP MODULES (MCMS) IS PROPOSED. THESE PROBES ARE CURRENTLY CAPABLE OF TESTING SEMICONDUCTOR DEVICES ON WAFERS AT FREQUENCIES UPTO 75 GHZ. PHASE I WILL SHOW THE ELECTRICAL… more
Abstract:TO COMMERCIALIZE HIGH ENERGY DENSITY, RECHARGEABLE LITHIUM (LI) POLYMER ELECTROLYTE-BASED BATTERIES, TWO PROBLEMS MUST BE SOLVED: (1) THE OPTIMIZATION OF THE CHARGE AND MASS TRANSFER PROPERTIES AT THE LI/ELECTROLYTE INTERFACE (OR THE LITHIUM CARBON COMPOSITE/ELECTROLYTE INTERFACE IN THE CASE OF A… 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.
