Abstract:AstroPower proposes to develop gallium phosphide (GaP) ultraviolet (UV) sensors for engine combustion control. The UV spectra from the free radial combustion components correlates with combustion effectivity in terms of predetonation, and provides a real time basis for central control of excess air… more
Abstract:Computer and engine studies demonstrated a 100% increase in diesel engine power with the use of 31% oxygen enriched air (OEA) versus standard 21% oxygen air. Additional benefits from OEA include: (1) improved fuel efficiency, (2) compatible with lower grade (volatility) fuels, (3) reduced CO and… more
Abstract:The investigators will develop a new class of perfluoropolymers with exceptionally high oxygen fluxmembranes for enhanced bioreactor performance. Propagation of animal cells for biopharmaceuticals iswidespread along with optimization of environmental constraints and procedures to increase… more
Abstract:Lanxide Corporation proposes to demonstrate the feasibility of utilizing the active brazing method to join a Nicalon TM fiber reinforced alumina matrix composite to structural alloys for applications i advanced turbine engines. The high temperature capability of the ceramic matrix composite allows… more
Abstract:ASTROPOWER PROPOSES TO DEVELOP A LIGHTWEIGHT, HIGH EFFICIENCY, MONOLITHICALLY INTERCONNECTED THIN SILICON SOLAR CELL ARRAY. THE ARRAY INCORPORATES AN INNOVATIVE TECHNIQUE TO ACHIEVE ELECTRICAL ISOLATION AND INTERCONNECTION OF THE ARRAY ELEMENTS. A MONOLITHICALLY INTERCONNECTED ARRAY TECHNOLOGY… more
Abstract:ASTROPOWER PROPOSES TO DEVELOP A NEW FRONT-ILLUMINATED, ALUMINUM GALLIUM PHOSPHIDE (AlGaP) BASED, CHARGE-COUPLED DEVICE (CCD), ULTRAVIOLET (UV) IMAGING ARRAY. THIS NOVEL ARRAY TECHNOLOGY HAS NEVER BEEN SUCCESSFULLY DEVELOPED. THREE NEW INNOVATIONS WILL BE NECESSARY TO ACOMPLISH THE AlGaP CCD. THESE… more
Abstract:A NOVEL SILICON DEPOSITION PROCESS CAPABLE OF DEPOSITING HIGH QUALITY THIN-FILM SILICON LAYERS ON LOW COST SUPPORTING SUBSTRATES WILL BE INVESTIGATED IN PHASE I. THE SUBSTRATE WILL INCLUDE A REFLECTOR FOR LIGHT TRAPPING. THE PLANNED DEPOSITION PROCESS WILL ALLOW THE FORMATION OF SILICON LAYERS 20… more
Abstract:INVESTIGATORS ARE DEVELOPING MONOLITHICALLY INTEGRATED BICOLOR EDGE EMITTER-DETECTOR PAIRS FOR WAVELENGTH-DIVISION MULTIPLEXING IN FIBER OPTIC COMMUNICATIONS. THIS DEVICE UTILIZES LATERALLY GRADED A1XGA1-XAS LAYERS FORMED BY LIQUID PHASE EPITAXIAL DEPOSITION ONTO A CONTINUOUSLY MOVING SUBSTRATE. … more
Abstract:THE SOLAR CELL APPLICATION OF CRYSTALLINE SILICON THIN-FILM, PHOTOCOLTAIC (PV) TECHNOLOGIES IS CURRENTLY LIMITED BY THE HIGH COST OF THE SILICON RAW MATERIAL. THIS IS A RESULT OF THE CARBOTHERMAL REDUCTION METALLURGICAL PROCESS USED TO CREATE THE SEMICONDUCTOR-GRADE SILICON FROM SILICA. THERE IS A… more
Abstract:AstroPower proposes to develop intense, mass-producible, low-cost 4 to 5 micron light-emitting diodes (LED's) using liquid-phase heteroepitaxy of lattice-matched InAsSb on GaSb substrates. The brightest visible LEDs (Ultrabrights) currently available are being produced commercially by the liquid… more
Abstract:REDUCTION OF AUTOMOBILE WEIGHT IS AN IMPORTANT APPROACH TO REDUCING FUEL CONSUMPTION. MAGNESIUM ALLOYS WOULD OFFER THE POTENTIAL FOR SIGNIFICANT WEIGHT REDUCTIONS IF THEY WERE MORE READILY FORMED AND THEIR STIFFNESS COULD BE INCREASED. HIGH STRAIN RATE SUPERPLASTIC FORMING OFFERS A COST EFFECTIVE… 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.
