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
Abstract:The Navy requires high energy density batteries to power underwater vehicles. The Li/LiX Co O2 cell has been identified as a promising redox couple for this particular application. A formidable stumbling block to the advancement of this technology resides in the inability of non-aqueous electrolytes… more
Abstract:We will synthesize and study fluorescent probes for hypoxic cells. The optical properties of the new compounds will be evaluated. Their ability to discriminate between hypoxic and oxic cells will be tested in cell cultures. These new probes will selectively bind to biomolecules in hypoxic cells.… more
Abstract:We propose to synthesize and test new fluorescent indicators for the lithium ion in aqueous solution. The indicators are designed to be water soluble and to respond selectively to Li+ by undergoing a shift in absorption and emission wavelengths. The proposed compounds will be of primary interest for… more
Abstract:There is a great deal of interest in implantable stimulation electrodes for use in neural prostheses. Such devices would be used to stimulate non-functional neural pathways to allow the recipient to regain control of muscles or improve optic and aural sensory input. Development of these devices has… 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.
