FULLERENES ARE A NEWLY DISCOVERED FORM OF CARBON (GRAPHITE AND DIAMOND ARE THE OTHER TWO FORMS) WITH DISTINCTIVE PROPERTIES AND AN UNUSUAL MOLECULAR STRUCTURE. PRELIMINARY INVESTIGATIONS INDICATED THAT FULLERENE ELECTRODE MATERIALS EXHIBIT UNIQUE ELECTROCHEMICAL PROPERTIES. IN THIS PHASE I EFFORT, FULLERNE NANOTUBE STRUCTURES WILL BE INVESTIGATED AS NOVEL ELECTRODE MATERIALS FOR LITHIUM ION STOR ...

COMMINUTION OF MINERALS BY BALL MILLING IS ENERGY INTENSIVE. ENERGY EFFICIENCY OF BALL MILLING RANGES FROM LESS THAN 1 PERCENT TO 10 PERCENT. BREAKAGE BY CRUSHING IS HIGHER IN EFFICIENCY BUT IS IMPRACTICAL FOR PRODUCTION OF A FINE MESHED PRODUCT. IT HAS BEEN ESTABLISHED IN LABORATORY TESTS THAT HIGH VELOCITY IMPACT BREAKAGE OF PARTICLES RESULTS IN COMPLETE BREAKAGE WHEREAS LOW VELOCITY IMPACTS ...

181 Epitaxial Growth of SiC on Silicon for Radiation Hard Particle Detectors--Lawrence Semiconductor Research Laboratory, Inc., 2300 West Huntington Drive, Tempe, AZ 85282-3130; (602) 438-2300 Dr. Richard Westoff, Principal Investigator Lamonte H. Lawrence, Business Official DOE Grant No. DE-FG03-97ER82416 Amount: $74,873 An immediate and critical need exists for radiation hard detectors tha ...

THIS RESEARCH PROJECT ADDRESSES THE DEMONSTRATION OF EPITAXIAL GROWTH, BY LASER ABLATION IN AN ULTRAHIGH VACUUM SYSTEM, OF HIGH QUALITY, WIDE-BANDGAP SEMICONDUCTOR FILMS ONTO HEATED SINGLE-CRYSTAL SILICON SUBSTRATES, FOLLOWED BY CHEMICAL VAPOR DEPOSITION (CVD) EPITAXIAL GROWTH OF SILICON ONTO THE WIDE-BANDGAP SEMICONDUCTOR. ON THE BASIS OF RECENT REPORTS OF SUCCESSFUL EPITAXIAL GROWTH OF CUBIC BOR ...

THIS WORK IS TO DEVELOP A METHOD TO IMPROVE THE ABILITY OF THE USNRC TO EVALUATE THE OPERATIONAL SAFETY SIGNIFICANCE OF OCCURANCES AT NUCLEAR POWER PLANTS. PERHAPS THE AREA OF GREATEST SAFETY SIGNIFICANCE IS HUMAN PERFORMANCE, BUT THE TECHNIQUES USED BY NRC DO NOT EVALUATE HUMAN PERFORMANCE IN ANY SYSTEMIC WAY. THE WORK IS PROPOSED TO BE PERFORMED IN THREE STAGES, AND BUILDS ON METHODS THAT HAVE B ...

THE DEEP CLEANING PROCESSES NOW UNDER INVESTIGATION FOR COAL MOST OFTEN INVOLVE PULVERIZING AND THE USE OF A LIQUID PROCESS MEDIUM. IF THE VERY FINE DEEP CLEANED COAL IS TO BE USED IN A DRY FORM, A SATISFACTORY DRYING TECHNOLOGY IS VITAL. PREVIOUS STUDIES HAVE INDICATED A SUBSTANTIAL PROBABILITY OF SUCCESS IF THE ULTRAHIGH LEVELS OF CENTRIFUGE GRAVITY ARE COMBINED WITH THE CENTRIFUGAL DECANTING/FI ...

16 Fiber Optic for the Detection of Co-Contaminant Compounds--F&S, Inc., P.O. Box 11704, Blacksburg, VA 24062-1704; (540) 953-4274 Mr. Mark E. Jones, Principal Investigator Ms. Garnett S. Linkous, Business Official DOE Grant No. DE-FG02-97ER82371 Amount: $74,994 Innovative technologies to advance the measurement of biological and physicochemical properties of natural systems are necessary in ...

FIELD-PORTABLE INSTRUMENTATION SUITABLE FOR ONSITE METAL ANALYSIS IS NEEDED. SUCH INSTRUMENTATION SHOULD PERMIT (1) ANALYSIS IN REAL TIME, (2) SIMULTANEOUS DETECTION OF VARIOUS METALS, AND (3) DETECTION LEVELS DOWN TO PARTS PER BILLION. IN PHASE I, THE SUITABILITY OF AN ELECTROCHEMICAL MEASUREMENT CONCEPT TO ACHIEVE THESE PERFORMANCE CHARACTERISTICS WILL BE ESTABLISHED. PHASE I CONSISTS OF THE FOL ...
