Abstract:We propose the exploration of single crystal GaN waveguides for the fabrication of optoelectronic integrated circuits. The feasibility of using GaN for short wavelength (up to 365 nm) OEIC's will be established in Phase I via the demonstration of a channel waveguide based phase shifter. The Al(sub… more
Abstract:We propose to demonstrate the design, fabrication, and performance of an integrated optic based device which provides for both multiplexing and independent external modulation of three closely spaced wavelengths emitted by a multi-longitudinal mode laser. The innovative aspect of the proposed device… more
Abstract:We propose a six month Phase I program to demonstrate the feasibility of growing A1N single crystals to serve as substrates for subsequent A1xGa1-xN epitaxy. Our approach is to use a low pressure, high temperature (2000 C) furnace with a temperature gradient between the A1N charge and the deposition… more
Abstract:AN EXTERNAL GUIDED WAVE OPTICAL MODULATOR WHICH PROVIDES THE COMBINATION OF HIGH BANDWIDTH, LOW INSERTION LOSS, AND LINEARITY IS BEING DEVELOPED. RESEARCHERS ARE DESIGNING, FABRICATING, AND TESTING A NOVEL MULTIPLE QUANTUM WELL ELECTROABSORPTION MODULATOR. IT OPERATES AT AN OPTICAL WAVELENGTH OF… more
Abstract:THE GOAL OF THE RESEARCH IS TO DEMYSTIFY THE SUBJECT OF IONIZING RADIATION FOR STUDENTS RANGING FROM MIDDLE SCHOOL TO GRADUATE SCHOOL. THE PREMISE OF THIS EFFORT IS THAT "SEEING IS BELIEVING". RESEARCHERS ARE MAKING RADIATION VISIBLE BY PUTTING A BUBBLE CHAMBER IN EACH STUDENT'S POCKET. THE BUBBLE… more
Abstract:The overall goal of this R&D program is to develop improved methodologies and manufacturingprocesses for the isolation of marine natural products with anticancer or anti-HIV activity. Thetherapeutic potential of marine natural products has rapidly advanced in recent years. One suchpotential… more
Abstract:This investigation is aimed at devising ways and special instrumentation for using fluorescentlanthanide chelates, detected by time resolved fluorometry, as a means for detecting nucleic acids in avariety of settings such as Southern blots and cells or tissues (e.g., as in situ hybridization).… more
Abstract:AN ADVANCED WASTE-WATER TREATMENT PROCESS FOR CONTINUOUS SEPARATIONOF IONIC SPECIES, INCLUDING HEAVY METALS, FROM AQUEOUS SOLUTIONS HAS BEEN DEVELOPED. THIS PROCESS SHOWS A POTENTIAL FOR SEPARATION OF A VARIETY OF COMPONENTS FROM COMPLEX MIXTURES AT SUFFICIENTLY HIGH CAPACITY AND LOW COST TO BE… more
Abstract:APOGEE CORPORATION IS ADDRESSING THE PROBLEM OF DEVELOPING A PROCESS FOR THE PRODUCTION OF POTABLE WATER AT SUFFICIENTLY HIGH CAPACITY AND LOW COST TO BE SUITABLE IN FARM PRODUCTION. WE HAVE CONCEIVED OF AN INNOVATIVE DESALINATION PROCESS NAMES ECS ABD PROVIDED A PROOF OF CONCEPT AND DEMONSTRATED… more
Abstract:Our efforts recently yielded a report describing the successful immunization of mice against theHIV-1 coat protein (gp160) using the technique of genetic vaccination. Animals were directly inoculatedwith DNA containing the HIV-1 gp160 gene, resulting in humoral and cellular immunity to the HIVgp160.… more
Abstract:WE HAVE BEEN DEVELOPING AN INSTRUMENT THAT ELECTRICALLY DETECTS CELL MOTION IN TISSUE CULTURE AND INTEND TO MAKE A COMMERCIAL DEVICE SUITABLE FOR THE MEDICAL/BIOLOGICAL RESEARCH MARKET. THE IMMEDIATE CHALLENGE IS TO RELATE MOTION OF CELLS MEASURED BY THIS METHOD TO OTHER RECOGNIZED CELLULAR… more
Abstract:MAPPING OF GENOMIC DNA WILL REQUIRE THE SEPARATION OF VERY LARGE DNA MOLECULES (CA. 0.1 TO 3000 MEGABASE-PAIRS (MBP)). WHILE SMALLER DNA MOLECULES (0.1-20 KILOBASE-PAIRS (KBP)) ARE EFFICIENTLY AND RAPIDLY RESOLVED BY THE CONVENTIONAL CONSTANT FIELD GEL ELECTROPHORESIS (CFGE), THE RESOLUTION OF DNA… more
Abstract:EMERGING FIFTH-GENERATION EDUCATIONAL ENVIRONMENTS ARE INCREASING THE FLOW OF INFORMATION BETWEEN THE STUDENT AND THE INSTRUCTIONAL DELIVERY SYSTEM TO LEVELS NEVER BEFORE POSSIBLE. ONE GROUP OF FIFTH-GENERATION SYSTEMS, CONCEPTUALLY DESCENDED FROM GRAPHICS-BASED SIMULATORS, USES VIRTUAL REALITY… more
Abstract:Computer-based data networks are entering the military tactical command and control environment. Mainstream network protocols were not designed for this environment and require considerable network management effort to use in situations as dynamic as tactical deployments. The introduction of mobile… more
Abstract:Carbon-carbon is a unique composite material that achieves the highest in-plane thermal conductivity and also achieves very high young's modulus (40-50 MSI). This research project will demonstrate the feasibility of C-C as an effective heat sink material for electronic packaging. Three to five… more
Abstract:The objective of this project is to develop an ultralightweight high thermal conductivity printed wiring board (PWB) constraining core mad of very high thermal conductivity carbon materials to replace currently used material constraining cores, e.g. copper-invar-copper. The objective of Phase I is… more
Abstract:The innovation being proposed in this project is the development of an ultra lightweight, noncontaminating dimensionally stable optical bench structural material product for small-sat applications. Candidate materials for the proposed structural material product, a sandwich structure, include:… 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.
