MCNC PROPOSES A FEASIBILITY STUDY AND EVALUATION OF THREE PROMISING APPROACHES TO THE FABRICATION OF SURFACE TEST STRUCTURES ON SILICON. SURFACE FEATURES ON THE FIRST STRUCTURE WILL BE PRODUCED BY CONTROLLABLY ETCHING THERMALLYGROWN OXIDES. FEATURES ON THE SECOND WILL BE MADE BY ETCHING PIEZOELECTRIC THIN FILMS. USING THE PIEZOELECTRIC FILM AS PART OF A CAPACITOR, STEP-HEIGHT CAN BE VARIED AND PRO ...

DNA AND BIOSEQUENCES ARE BEING DETERMINED FASTER THAN THEY CAN BE COMPARED AND ANALYZED. PRESENT TECHNIQUES FOR RIGOROUSLY SEARCHING A LARGE DATABASE ARE COSTLY AND TIME CONSUMING. UNDER ALL PLAUSIBLE GROWTH PROJECTIONS, THE PROBLEM WILL SOON BECOME OVERWHELMING. A CUSTOM, VERY LARGE SCALE INTEGRATED CIRCUIT THAT COULD BE USED FOR HIGH SPEED COMPARISON, ANALYSIS, AND INTERPRETATION OF DNA AND PROT ...

BORON NEUTRON CAPTURE THERAPY (BNCT) HAS A CLEAR THEORETICALADVANTAGE OVER OTHER TECHNIQUES AS A METHOD OF DELIVERING CELL-KILLING RADIATION TO CANCEROUS TUMORS. COMPOUNDS CONTAINING THE ELEMENT BORON, SUCH AS BORONOPHENYLALANINE (BPA), CAN ALSO SELECTIVELY LOCALIZE IN SKIN CANCERS SUCH ASMALIGNANT MELANOMA. UPON IRRADIATION BY A THERMAL OR EPITHERMAL NEUTRON BEAM, THE COMPOUND PRODUCES LOCALIZED ...

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 ...

THIS PROJECT EMPLOYS A TWO-PART DESIGN STUDY FOR HIGH CURRENT, HEAVY ION, RECIRCULATING INDUCTION ACCELERATORS FORINERTIAL FUSION INVOLVING: (1) MODULATOR CIRCUIT DESIGN FOR RECIRCULATING ACCELERATORS, BASED PARTICULARLY ON RECENT ADVANCES IN HIGH POWER SWITCH TECHNOLOGY, AND (2) OPTIMUM RECIRCULATOR DESIGN TO MAKE THE BEST USE OF ADVANCES IN THE SWITCHES AND CIRCUITS. RECENT DOE STUDIES HAVE SHOW ...

THIS RESEARCH AIMS TO DEVELOP AN IMPROVED SOURCE OF MULTIPLY-CHARGED IONS FOR HEAVY-ION INERTIAL FUSION AND OTHER APPLICATIONS THAT REQUIRE VERY HIGH BRIGHTNESS. A CONVENTIONAL GAS-DISCHARGE SOURCE IS PLANNED THAT DEPENDS ON THE COMBINATION OF TWO ADDITIONAL NOVEL FEATURES. FIRST, THE INITIAL DENSE HOT PLASMA GAS GENERATED FROM A HIGH PRESSURE MICROCAPILLARY DISCHARGE IS FURTHER HEATED BY A LASER ...
