THE PROBLEM OF OXIDATION IN THE HOT SECTIONS OF A MODERN JET ENGINE IS SERIOUS. IT IS SAID THAT A JET ENGINE WITH UNPROTECTED TURBINE BLADES CANNOT MAKE A SINGLE TRANSATLANTIC FLIGHT BECAUSE OF OXIDATION. NICKEL-BASE SUPERALLOYS THAT ARE USED IN THE HOT SECTIONS ARE PROTECTED BY OXIDATION RESISTANT SURFACE COATINGS. THE COATING TECHNOLOGY FOLLOWS THE DEVELOPMENT IN NICKEL-BASE SUPERALLOYS. THERE I ...

DURING THE LAST 25 YEARS THE DENSITY OF COMPUTER ELECTRONIC CIRCUITRY HAS INCREASED BY FIVE ORDERS OF MAGNITUDE. THIS DRIVE TOWARD MORE DENSELY PACKAGED MICROELECTRONICS HAS RESULTED IN A DRAMATIC INCREASE IN THE AMOUNT OF WASTE HEAT WHICH MUST BE DISSIPATED. HEAT FLUX RATES IN CURRENT LSI CIRCUITRY ARE ALREADY AS HIGH AS 20 W/CM2 AND PROJECTED LEVELS FOR VLSI AND FUTURE ADVANCED CIRCUITRY CONFIGU ...

THE COLLAPSE OF A STEAM BUBBLE IN A POOL OF SUBCOOLED WATER IS KNOWN TO RESULT IN THE RADIATION OF PRESSURE WAVES OF ENORMOUS MAGNITUDE. THESE PRESSURE WAVES CAN BE USED TO FRACTURE MATERIALS AND/OR REMOVE MATERIAL IF THEY CAN BE DIRECTED. DEVELOPMENT OF A NOZZLE IS PROPOSED WHICH WILL DIRECT COLLAPSING STEAM BUBBLES TOWARDS A SURFACE AND SET UP STRESS WAVES IN THE SOLID WHICH WILL RESULT IN SURFA ...

THE OXYGEN MOLECULE HAS A NUMBER OF WEAK ABSORPTION LINES INTHE 7000 A SPECTRAL REGION. BY COOLING, THE R1 LINE OF RUBY(A12O3 : CR+3) CAN BE SHIFTED TO COINCIDE WITH 50% ABSORPTION AT LINE CENTER IN THE SOLAR SPECTRUM. RUBY FLUORESCES WITH HIGH QUANTUM EFFICIENCY, WITH A TIME CONSTANT OF APPROXIMATELY 4 MS AT THE TEMPERATURES OF INTEREST. BY DETECTING THE RERADIATED LIGHT, THE RUBY CRYSTAL IS USED ...

THE PROPOSED RESEARCH WILL INVESTIGATE THE DEPOSITION OF AMORPHOUS CARBON THIN FILMS USING A NOVEL LASER ASSISTED DEPOSITION TECHNIQUE. IN THE PHASE I RESEARCH, AERODGNE RESEARCH, INC. WILL DETERMINE THE ABILITY OF THE DEPOSITION TECHNIQUE TO CONTROL THE CARBON BONDING IN THE THIN FILM. IN THE PHASE II STUDIES THEY WILL INVESTIGATE THE RELATIONSHIP BETWEEN DEPOSITION PARAMETERS AND CARBON BONDING ...

A NOVEL CONCEPT IS PROPOSED FOR THE SYNTHESIS OF INTRINSICALLY CONDUCTIVE POLYMERS. THE CONDUCTIVE POLYMERS PPOLYDIACETYLENES WILL BE SYNTHESIZED BY THE SOLID-STATE POLYMERIZATION OF DIACETYLENES POLARIZABLE GROUPS, EITHER UPON THERMAL ANNEALING OR UPON EXPOSURE TO HIGH-ENERGY RADIATION. THE RESULTANT CONDUCTIVE POLYDIACETYLENES COULD BE CRYSTALLINE, INTRINSICALLY CONDUCTIVE, AND ENVIRONMENTALLY S ...
