SURFACE METAL OXIDE AND OXYHYDROXIDE LAYERS HAVE BEEN IMPLICATED AS TRITIUM TRAPS IN STAINLESS STEELS. A NEW TECHNIQUE IS BEING DEVELOPED FOR MEASURING HYDROGEN ISOTOPE DIFFUSION WITHIN THIS LAYER AND WITHIN PERMEATION BARRIERS MEANT TO LIMIT TRITIUM INVENTORY IN THESE MATERIALS.

BLENDS OF BIOBASED FIBER SOURCES ARE MANUFACTURED AND CHARACTERIZED BY ASPECT RATIO FOR OPTIMUM PERFORMANCE IN A BIOBASED GRAFT POLYMER AS MEASURED BY MECHANICAL PROPERTIES AND SURFACE MORPHOLOGY IN COMPRESSION MOLDED TEST SPECIMENS. FROM 18 FORMULATIONS OF BIOBASED GRAFT POLYMER, THREE ARE SELECTED ON THE BASIS OF BEST OVERALL PERFORMANCE AND USED IN A BIOBASED GRAFT POLYMER COMPOSITE STUDY IN CO ...

THE U.S. HAS AN ESTIMATED 327 BILLION BARRELS OF OIL IN EXISTING PRODUCTION FIELDS WHICH REMAINS IN PLACE EVEN AFTERPRIMARY AND SECONDARY RECOVERY TECHNIQUES HAVE BEEN EMPLOYED. HIGH RESOLUTION BOREHOLE-TO-BOREHOLE SEISMIC TOMOGRAPHY CAN PROVIDE THE INFORMATION NEEDED TO LOCATE THESE UNPRODUCED REGIONS THROUGH THE IDENTIFICATION OF SUBTLE GEOLOGIC ANOMALIES AND CAN BE USED TO ASSESS THE PROGRESS O ...

THERE IS A RENEWED INTEREST IN FUEL CELLS AS PRIMARY POWER SOURCES FOR ELECTRIC VEHICLES. THE ACIDIC PROTON EXCHANGE MEMBRANE FUEL CELL OPERATES AT A MAXIMUM TEMPERATURE OF 95 DEGREES CENTIGRADE AND, AT PRESENT, RELIES ON THE USE OF PLATINUM-BASED ELECTROCATALYSTS. FOR ACID FUEL CELLS OPERATING AT TEMPERATURES BELOW 130 DEGREES CENTIGRADE, HYDROGEN IS THE MOST ACTIVE COMMON FUEL THAT CAN BE USED ...

THE TARGET OF THE PROPOSED PROCESS IS TO CONVERT NATURAL GASFROM SMALLER OR LARGER NATURAL GAS SOURCES (INCLUDING SMALL OUTLYING GAS WELLS OR CO-PRODUCED GAS OUT OF A CRUDE OIL PRODUCING WELL) INTO CRUDE METHANOL AND HYDROCARBONS, AND CENTRALLY CONVERT THESE CRUDE LIQUIDS FURTHER INTO COMPONENTS FOR GASOLINE USE. A LOW-COST PROCESS FOR THESE CONVERSIONS HAS BEEN INVENTED BY DR. VAN DIJK AND MR. FR ...

106 Crosswell Seismic in Three Dimensions--TomoSeis, Inc., 1650 West Sam Houston Parkway North, , Houston, TX 77043-3115; (713) 461-7360 Dr. Spyros Lazaratos, Principal Investigator Mr. Bruce P. Marion, Business Official DOE Grant No. DE-FG03-97ER82502 Amount: $74,997 Improved recovery of oil and gas from mature domestic fields depends on the detailed characterization of reservoir st ...

A PROGRAM IS PROPOSED TO SHOW THE FEASIBILITY OF DEPRESSED COLLECTORS FOR VERY HIGH AVERAGE POWER (APPROX. 1MW) GYROTRON OSCILLATORS FOR FUSION APPLICATIONS. INITIAL CALCULATIONS INDICATE THAT COLLECTION EFFICIENCIES EXCEEDING 75% CAN BE REALIZED. USE OF SUCH A COLECTOR ON A GYROTRON WITH A BASE EFFICIENCY OF 30% WOULD INCREASE THE EFFICIENCY TO OVER 60%. SUCH A DRAMATIC INCREASE IN EFFICIENCY WOU ...

THIS PROJECT IS AIMED AT THE DEVELOPMENT OF A NEW GENERATION OF ROTARY BLOWOUT PREVENTERS CAPABLE OF SAFE, RELIABLE, AND COST EFFECTIVE HANDLING OF THE HIGH PRESSURES EXPECTED IN UNDERBALANCED HORIZONTAL AND DIRECTIONAL DRILLING APPLICATIONS. PRESSURES OF UP TO 5,000 PSI (OR EVEN HIGHER) CAN BE EXPECTED WHEN DRILLING WITH AIR, FOAM, OR NITRIFIED MUD IN THE LOW PERMEABILITY FORMATIONS IN THE U.S. ...
