WORKERS AT BRIGHAM YOUNG UNIVERSITY, BIPOLAR TECHNOLOGIES, HAVE DEVELOPED A MATERIAL FOR USE AS A BIPOLAR ELECTRODE SUPPORT WHICH WILL RESULT IN MORE LIGHTWEIGHT, LONGER LIFE BATTERIES. THE ELECTRODE SUPPORT IS A COMPOSITE MATERIAL COMPOSED OF LOW SURFACE AREA CARBON/POLYMER COMPOSITE MATERIAL WHICH HAS LOW ELECTRICAL RESISTANCE, CHEMICALLY STABLE, AND HAS LOW ACTIVITY FOR OXYGEN EVOLUTION, AN UND ...

A compact x-ray laser driver with a high repetition rate is the subject of this phase I project. Most existing x-ray laser drivers are huge (1000s of square feet of floor space), expensive ($10,000,000+), have a low repetition rate (1/hr), are complex and require several PhDs to keep them working. Thus applications of present x-ray lasers are limited. In contrast, the proposed laser will occupy on ...

Sarcos is currently developing a technology that can lead to low-cost millimeter-scale gyroscopes, multi axis inertial sensors, and very compact laser scanning devices. This technology, called Micro Disk Systems (MDS), is based on levitating a small disk above a VLSI substrate using electrostatic fields. AC stabilization of the fields ensures that the disk position remains suitable, and field-base ...

AN ADVANCED REACTOR WITH A 50-75% EFFICIENT ELECTRICAL ENERGY CONVERSION PROCESS INCORPORATED WITHIN A CORE COMPRISED OF FUEL AND MODERATOR PROVIDES OPTIONS HERETOFORE UNREALIZED. IN PRINCIPLE, THE REQUIREMENTS FOR THE FEASIBILITY OF SUCH A COMPACT REACTOR COULD BE MET WITH THE DEVELOPMENT OF ENERGY CONVERSION MATERIALS THAT COULD OPERATE EFFICIENTLY IN THE HOSTILE RADIATION ENVIRONMENT OF SUBSTAI ...

CAPACITOR TECHNOLOGY IS A MAJOR DRIVER FOR THE SIZE AND COST OF MANY SPACE POWER CONDITIONING SYSTEMS. CURRENT TECHNOLOGY FOR HIGH VOLTAGE (>100V), HIGH FREQUENCY (HIGH REP RATE) CAPACITORS IS LIMITED TO AN ENERGY DENSITY LESS THAN 7500 J/M3. WE ARE PROPOSIING A REVOLUTIONARY CAPACITOR TECHNOLOGY WHICH PROMISES TO INCREASE CAPACITOR ENERGY DENSITIES BY AFACTOR OF MORE THAN 100. IN MANY APPLICATION ...

THE PROPOSED PROGRAM USES POLARIZATION REVERSAL ON FERROELECTRIC MATERIALS THAT YIELD CURRENT DENSITIES IN THE kA/cm2 RANGE. THE FAST CHANGE IN THE POLARIZATION VECTOR WITHIN THE MATERIAL RESULTS IN A TRANSITION THAT LIBERATES THE POLARIZATION INDUCED CHARGES (4 P) RESULTING IN A CURRENT PULSE LIMITED ONLY BY THE TRANSITION TIME AND SPACE CHARGE EFFECTS. THE PROPOSED PROGRAM WILL DEVELOP THE TECHN ...

THE SUCCESS OF FUTURE SPACE MISSIONS IS DEPENDENT ON THE DEVELOPMENT OF ADVACNED RADIATORS. THIS PROPOSAL DESCRIBES A NOVEL, LIGHTWEIGHT, INTERIOR CAPILLARY PUMPED LOOP (CPL) DESIGN THAT CAN BE USED FOR AMBIENT TEMPERATURE HEAT REJECTION. THE HEAT PIPE RADIATING SYSTEM IS EXTREMELY LIGHTWEIGHT DUE TO ITS INTERIOR CPL DESIGN WHICH REQUIRES WICK STRUCTURE ONLY IN THE EVAPORATOR, AND ITS INNOVATIVE M ...

THIS PROPOSAL CONCERNS THE DEVELOPMENT OF A NOVEL ENERGY SOURCE FOR SDI APPLICATIONS. HYDROGEN IS USED AS A FUEL; POWER PRODUCING ELECTROLYTIC CELL TECHNOLOGY IS USED FOR THE CATALYTIC PROCESS; ELECTROLYSIS IS NOT REQUIRED. THE RESULT IS A PASSIVE, SELF SUSTAINING NON-ELECTROLYTIC METHOD FOR EXTRACTING ENERGY FROM HYDROGEN. HYDROGEN IS SUPPLIED TO A CATALYST AND ENERGY ID PREDICTED USING THIS PROC ...

THERMACORE HAS RECENTLY DEMONSTRATED HEAT FLUXES IN EXCESS OF 6000 W/cm2 AND HEAT TRANSFER COEFFICIENTS OF NEARLY 100 W/cm2 - DEGREE C USING AN APPROACH CALLED POROUS METAL HEAT TRANSFER,USING COPPER AS THE HEAT EXCHANGER MATERIAL, AND WATER AS THE COOLANT. THE PROPOSED PROGRAM WILL MEET ALL SEMICONDUCTOR LASER ARRAY COOLER (SLAC) REQUIREMENTS BY ADAPTING POROUS METAL HEAT TRANSFER USING APPROPRIA ...

An extremely sensitive, low power, high durability solid state atomic oxygen sensor system with the potential for cost effective fabrication is proposed. It should lead to 1) improved understanding of the levels of atomic oxygen encountered during space missions; 2)quantification of the effects of atomic oxygen on a variety of materials in the space environment; 3) a warning mechanism for potentia ...
