THE PHASE I EFFORT HAS SUCCESSFULLY DEMONSTRATED THAT COMBINING SOL-GEL CHEMISTRY WITH MICROWAVE HEATING CAN RESULT IN THE FABRICATION OF A CERAMIC HIGH TC SUPERCONDUCTOR (HTS) IN ABOUT AN HOUR. SOL-GEL PROCESSING RESULTED IN UNIFORM MICRON-SIZED PRECURSOR POWDERS WITH THE DESIRED STOCHIOMETRY. THIS POWDER WAS SUBSEQUENTLY HEATED FOR 70 MINUTES UNDER SPECIFIC CONDITIONS IN A MODIFIED MICROWAVE OVE ...

THERE IS A REQUIREMENT FOR A RELIABLE, SECURE METHOD FOR RETRIEVAL OF DATA FROM MOORED INSTRUMENTATION ARRAYS. THESEARRAYS, WHICH CONTAIN CURRENT METERS, TIDE GAUGES, TEMPERATURE SENSORS, AND OTHER OCEANOGRAPHIC INSTRUMENTS, ACQUIRE AND STORE DATA OVER A PERIOD OF WEEKS OR MONTHS AND THEN ARE RETRIEVED, THE RESTORED DATA RECOVERED, AND THE INSTRUMENTS REDEPLOYED. RETRIEVAL AND DEPLOYMENT IS AN EXP ...

THIS PROJECT WILL RESULT IN HIGH SPEED, LOW COST SPATIAL LIGHT MODULATORS WITH APPLICATIONS INCLUDING OPTICAL PROCESSING, HOLOGRAPHIC MEMORIES, HDTV, AND FLAT-PANEL DISPLAYS. THESE SLMS ARE MICRO-MECHANICAL AND WILL BE FABRICATED ON GLASS OR PLASTIC SUBSTRATES USING EFFICIENT DIELECTRIC MATERIALS AND MATURE, LOW-COST/HIGH VOLUME VACUUM COATING TECHNOLOGIES. CHARACTERISTICS INCLUDE SUB-MICROSECOND ...

FOSTER-MILLER PROPOSES AN INNOVATIVE TECHNIQUE TO FABRICATE ALL POLYMER, ULTRAHIGH ENERGY DENSITY DOUBLE LAYER CAPACITORS TO MEET SPACE POWER CONDITIONING NEEDS OF THE SDI. THE FOSTER-MILLER APPROACH IS BASED ON INFILTRATING AN IONICALLY CONDUCTING POLYELECTROLYTE WITH THE MONOMER OF AN ELECTRICALLY CONDUCTING POLYMER. THE MONOMER WILL BE POLYMERIZED "IN-SITU" ACHIEVING A HIGH DEGREE OF MOLECULAR ...

A SOLID STATE SWITCH FOR OPERATION AT CRYOGENIC TEMPERATURE IS BEING DEVELOPED THAT WILL PROVIDE MULTI-MEGAWATT POWER CONDITIONING IN THE RAPIDLY EXPANDING FIELD OF LOW TEMPERATURE ELECTRONICS. SINCE EXISTING CONTROLLED SWITCHES ARE NOT DIRECTLY SUITABLE FOR CRYOGENIC OPERATION, ONLY A FUNDAMENTAL APPROACH CAN DEVELOP STRUCTURES CAPABLE OF LOW LOSS AND RELIABLE OPERATION IN THE TEMPERATURE RANGE B ...

THE ADVANTAGES OF SILICON CARBIDE AS A HIGH TEMPERATURE, RADIATION TOLERANT SEMICONDUCTOR MATERIAL ARE WELL KNOWN. UNLIKE COMPARABLE MATERIALS, SUCH AS DIAMOND, PREPARATION OF FUNCTIONAL DEVICES HAS BEEN RELATIVELY STRAIGHT FORWARD WITH THE MAJOR LIMITATION CONTINUING TO BE THE DEFECT DENSITY OF THE SUBSTRATE MATERIAL. A METHOD IS PROPOSED USING ION BEAM SYNTHESIS TO PRODUCE SINGLE CRYSTAL, LOW DE ...
