  1. An Innovative Technique of Preparing Solar Grade Silicon Wafers from Metallurgical Grade Silicon by In-Situ Purification

    SBC: GT Equipment Technologies, Inc.            Topic: 39a

    75655S The photovoltaics (PV) industry is having difficulty finding enough raw materials to match its rapid growth. In addition, traditional sources of secondary grade polysilicon are no longer readily available at inexpensive prices. Reducing the cost of solar silicon wafers is the key to lowering the price of crystalline silicon solar cells. This project will develop a single-step wafer fabr ...

  2. A CLEAN HELIUM COMPRESSOR/EXPANDER FOR LONG LIFE CRYOGENIC SERVICE

    SBC: CREARE LLC            Topic: N/A

    CRYOGENIC HELIUM REFRIGERATORS AND LIQUIFIERS CONVENTIONALLYEMPLOY OIL LUBRICATED POSITIVE DISPLACEMENT COMPRESSORS AT THE WARM END AND FREQUENTLY USE PISTON TYPE EXPANSION ENGINES AT THE COLD END. THESE SYSTEMS REQUIRE EXTENSIVE AND VIGILANT MAINTENANCE TO CONTROL CONTAMINATION FROM LUBRICATING OIL AND ITS VOLATILE COMPONENTS MIGRATING TO THE COLD END. HENCE THE NEED FOR LOW MAINTENANCE COMPRESSO ...

  3. ALL-METAL, DEMOUNTABLE CRYOGENIC SEAL

    SBC: CREARE LLC            Topic: N/A

    IN MOST CRYOGENIC SYSTEMS, THE PIPING JOINTS IN COLD REGIONSOF THE SYSTEM ARE MADE BY WELDING OR SOLDERING. THIS IS ESSENTIAL BECAUSE EXISTING DESIGNS OF CRYOGENIC PIPE SEALS CANNOT BE RELIED ON NOT TO LEAK. ANY SUCH LEAKS INTO THE COLD BOX REDUCE THE EFFECTIVENESS OF THE INSULATION, THEREBY REDUCING THE EFFICIENCY OF THE REFRIGERATOR. WELDEDJOINTS MAKE REPLACEMENT OF COMPONENTS DIFFICULT AND HAVE ...

  4. Model-Based Design of Test Systems for Chemical Protective Clothing

    SBC: CREARE LLC            Topic: CBD02202

    The current methodology for testing the penetration resistance of textile materials to various chemical agents has a number of drawbacks, including significant uncertainties in the resulting data, inefficiency and expense, risk to test personnel, and limited range of test conditions. The objective of the proposed work is to apply unique computer models for textiles with accompanying experimental ...
