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 ...

THIS RESEARCH AIMS TO DEMONSTRATE THE UTILITY OF EMPLOYING NOVEL FIBER-OPTIC SENSORS FOR USE IN HIGH PRESSURE AND HIGH TEMPERATURE ENVIRONMENTS. THE PLANNED SENSOR DESIGN EMPLOYS A NOVEL "SURFACE COMPOSITE" CONTAINING SOL-GEL COATINGS AND IMMOBILIZED FLUORESCENT ORGANIC COMPOUNDS. THE FIRST GOAL IS TO CHARACTERIZE AND DISCOVER WHAT FACTORS GOVERN THE ANALYTICAL FIGURES OF MERIT. TWO SPECIFIC SENSO ...

THE FUNDAMENTAL GOAL FOR THIS RESEARCH EFFORT IS TO DEVELOP A GREATER UNDERSTANDING OF THE DYNAMICAL PROCESSES ASSOCIATED WITH EAST COAST COLD SEASON SEVERE CONVECTIVE EVENTS AND TO NUMERICALLY SIMULATE THESE EVENTS IN ORDER TO PROVIDE HIGHER QUALITY OBJECTIVE GUIDANCE TO THE FORECASTER. THE PHASE I OBJECTIVE IS TO SHOW THE FEASIBILITY OF USING A MESO-B SCALE DYNAMICAL MODEL TO ASSIST IN THE REAL- ...

THE OBJECTIVE OF THIS RESEARCH PROJECT IS TO DEVELOP IMPROVED AMPEROMETRIC BIOSENSORS BASED ON NEW POLYMERIC ELECTRON RELAY SYSTEMS THAT CAN ELECTROCATALYTICALLY REOXIDIZE THE NICOTINAMIDE ADENINE DINUCLEOTIDE (NAD) COFACTOR. THE NAD-DEPENDENT DEHYDROGENASES CONSTITUTE THE LARGEST GROUP OF REDOX ENZYMES KNOWN TODAY. BY USING THIS METHOD OF FACILITATING ELECTRON TRANSFER FROM THE ENZYME TO THE ELEC ...

SURPLUS OFFSHORE OIL PLATFORMS AND SIMILAR STRUCTURES HAVE POTENTIAL AS BASES FOR THE SUPPORT OF OFFSHORE AQUACULTURE OPERATIONS. ONE CONCEPT DEVELOPED AT NET SYSTEMS ENVISIONS A PLATFORM SURROUNDED BY, AND HELPING TO SUPPORT, A RINGSHAPED ARRANGEMENT OF FLOATING FISH PENS. HOWEVER, BEFORE SUCH STRUCTURES CAN BE INCORPORATED INTO AQUACULTURE SYSTEMS, WE NEED TO BE ABLE TO PREDICT THEIR RESPONSE TO ...

A DATA ACQUISITION INTERFACE IS BEING DEVELOPED FOR ELEMENTARY PARTICLE PHYSICS DATA TRANSPORTED ON OPTICAL FIBER AT BANDWIDTHS UP TO ONE GIGABIT PER SECOND. THE INTERFACE IS INTENDED AS A DEVELOPMENT TOOL DURING THE ENGINEERING OF PROTOTYPE DATA ACQUISITION ELECTRONICS FOR USE IN FUTURE LARGE HIGH BANDWIDTH EXPERIMENTS SUCH AS THOSE AT THE SUPERCONDUCTING SUPER COLLIDER (SSC). NO PARTICULAR FORMA ...
