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 THEORETICAL PROGRAM IS PROPOSED TO INVESTIGATE A COMPACT, LOW-VOLTAGE INFRARED GRATING LASER WITH MULTI-KILOWATT OUPUT CAPABILITY. THE RADIATION IS GENERATED BY THE PASSAGE OF AN ANNULAR BEAM OF ELECTRONS THROUGH A COAXIAL PAIR OF CONDUCTORS, THE INNER CONDUCTOR BEING A CORRUGATED CYLINDER WHICH FORMS THE GRATING. THE ELECTRON BEAM IS GUIDED BY AN AXIAL MAGNETIC FIELD. THE DIMENSIONS OF THE OPTI ...

MANY CURRENT AND PLANNED DEFENSE AEROSPACE PROGRAMS DEPEND CRITICALLY UPON RAPID DEVELOPMENT OF LIGHTWEIGHT COMPOSITE MATERIALS HAVING UNPRECEDENTED HIGH-TEMPERATURE PROPERTIES. CONTINUOUS FIBER REINFORCED INTERMETALLIC MATRIX COMPOSITES (IMC'S) HAVE THE POTENTIAL TO MEET THESE PERFORMANCE REQUIREMENTS, AND CONSIDERABLE RESEARCH EFFORT IS NOW DEVOTED TO DEVELOPING THEM. WE RECENTLY DEMONSTRATED A ...

OPTICS USED IN SENSORS OR MISSILE SYSTEMS ARE MADE FROM SAPPHIRE, OR SILICON CARBIDE BECAUSE OF THEIR EXCELLENT OPTICAL OR INSULATING PROPERTIES, THEIR INERT, AND THEIR ABILITY TO RESIST HARSH ENVIRONMENTS. POLISHING SAPPHIRE BY MECHANICAL OR MECHANOCHEMICAL METHODS INDUCES RESIDUAL DAMAGE AND LIMITS THE OVERALL SURFACE ROUGHNESS (USUALLY AROUND 1 MICROINCH). THIS ROUGHNESS PRODUCES SCATTERING CEN ...

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 ...

Certain ferro-magnetic (F/M) materials expand and/or contract in the presence of an electrical current or field. This program proposes basic and applied research to use this material property as the working medium to achieve quantum improvements in the performance of miniature actuators. Using this exciting new solid state technology, it appears possible to create ultra-fast response, high force, ...

ENGINE ELECTRIC HIGH-SPEED MAGNETOSTRICTIVE MATERIAL LONG-LIFE PROPULSION RESEARCH INC WILL DEVELOP AN ULTRA-EFFICIENT, HIGH POWER LOW WEIGHT COMPACT ELECTRIC ENGINE USING A REVOLUTIONARY PHYSICAL CONCEPT. IT WILL ALLOW THE CREATION OF ELECTRIC POWERED ENGINES FOR USES IN EVERYTHING FROM "WEED-WACKERS" TO SUBMARINE ENGINES. THESE ENGINES HAVE THE POTENTIAL FOR HIGH STARTING AND RUNNING TORGUE, HIG ...
