ALUMINUM NITRIDE (A1N) IS AN IMPORTANT CANDIDATE MATERIAL FOR ADVANCED PACKAGING OF INTEGRATED CIRCUITS AS A HIGH THERMAL CONDUCTIVITY ALTERNATIVE TO BERYLLIUM OXIDE THAT COULD POTENTIALLY BE MADE AVAILABLE AT LOW COST. MUCH EXPERIMENTAL WORK HAS BEEN CONDUCTED ON A1N, BUT THE TECHNOLOGY STILL HAS NOT REACHED A LEVEL SUITABLE FOR APPLICATION. ADVANCES ARE NEEDED ESPECIALLY IN SINTERING TECHNOLOGY ...

OVER THE PAST FEW YEARS, A NEW FAMILY OF MATERIALS CALLED NZP (NAZR2 (PO4)3 AND ITS ANALOGS) HAS BECOME WELL KNOWN FORITS LOW THERMAL EXPANSION BEHAVIOR. RECENTLY, IT HAS BEEN SHOWN THAT ZR4 (PO4)6 AND SRZR4(PO4)6 HAVE OPPOSITE ANISOTROPY IN THERMAL EXPANSION AS WELL AS OPPOSITE BULK THERMAL EXPANSION AND THAT THEIR SOLID SOLUTION RESULTS IN LOWER ANISOTROPY AND NEAR ZERO THERMAL EXPANSION. THESE ...

CERAMIC-MATRIX COMPOSITES WITH OPTIMUM FIBER-MATRIX INTERFACIAL BONDING EXHIBIT HIGH STRENGTHS, FRACTURE TOUGHNESS, AND A DAMAGE-INSENSITIVE FAILURE MODE, AND THEY ARE VASTLY SUPERIOR IN RELIABILITY TO MONOLITHIC CERAMICS. THE DESIGN AND FABRICATION OF THESE COMPOSITES REQUIRE INNOVATIVE TECHNIQUES TO CONTROL, MODIFY, AND CHARACTERIZE THE FIBER-MATRIX BONDING. TWO NOVEL TECHNIQUES FOR MEASURING TH ...

THIS PROGRAM WILL INVESTIGATE ADVANCED ABRASIVE WATERJET (AWJ) TECHNIQUES TO FACILITATE THE DECONTAMINATION AND DECOMMISSIONING OF NUCLEAR FACILITIES. TWO SPECIFIC NEEDS ARE TO BE ADDRESSED: METAL SURFACE REMOVAL FOR COMPLETE DECONTAMINATION OF LARGE, HEAVILY CONTAMINATED METAL STRUCTURES AND UNDERWATER CUTTING OF THICK METALS AND CONCRETE. AN AWJ IS A SMALL DIAMETER ULTRA HIGH VELOCITY WATERJET I ...

N/A

A CATALYTIC COMBUSTION FLOW CALORIMETER FOR THE MEASUREMENT OF NATURAL GAS ENERGY CONTENT WILL BE DEVELOPED AND TESTED. THIS NEW CALORIMETER (GAS ENERGY METER) WILL BE DESIGNED TO BE A PROTOTYPE FOR DEVELOPMENT OF AN INSTRUMENT SUITABLE FOR REMOTE INSTALLATION, AS ACCURATE AS PRESENT LABORATORY CALORIMETERS, OPERABLE CONTINUOUSLY FOR PRECISE ACCOUNTING AT CUSTODY TRANSFER POINTS, AND LOW IN COST. ...

COAL LIQUEFACTION TECHNOLOGY HAS BEEN DEVELOPED TO THE STAGEWHERE SUCCESSFUL PILOT PLANTS ARE NOW IN OPERATION IN THE UNITED STATES. HOWEVER, ECONOMIC AND ENVIRONMENTAL CONCERNS HAVE CURTAILED PLANS FOR COMMERCIAL VENTURES. BY SOLUBILIZING OXIDIZED COAL WITH THE HELP OF LIGNIN-DEGRADINGMICROORGANISMS, RESEARCHERS HAVE BEEN ABLE TO CONVERT COAL TO WATERSOLUBLE DEGRADATION PRODUCTS. THIS FORM OF BIO ...

N/A

BLACK LIQUOR IS A WASTE LIQUID FROM KRAFT WOOD PULPING. IT CONTAINS USED INORGANIC CHEMICALS AND ORGANIC WOOD RESIDUE. BLACK LIQUOR IS BURNED IN RECOVERY BOILERS TO RECOVER THE PULPING CHEMICALS FOR REUSE AND TO GENERATE STEAM FOR POWER GENERATION AND MILL CONSUMPTION. BECAUSE OF THIS DUAL FUNCTION THE OPERATION OF A RECOVERY BOILER IS PARTICULARLY DEMANDING. SUCCESSFUL COMBUSTION OF BLACK LIQUOR ...
