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 ...

THE PRIMARY OBJECTIVE OF THIS PROJECT IS TO DETERMINE THE FEASIBILITY OF INCREASING THE QUANTITY AND QUALITY OF SCIENCE EDUCATION IN ELEMENTARY SCHOOLS THROUGH UTILIZING SCIENCE EDUCATION AS THE CONTENT OF CHOICE FOR A RELATIVELY NEW ADDITION TO THE ELEMENTARY SCHOOL CURRICULUM, FOREIGN LANGUAGE. THE INCLUSION OF FOREIGN LANGUAGE IN THE ELEMENTARY SCHOOL, MORE COMMONLY CALLED FLES, IS A RAPIDLY GR ...

A COMMON DILEMMA IN ECOSYSTEM MODELING IS THE COMPLEXITY OF BIOLOGICAL SYSTEMS AND THE LACK OF SUFFICIENT DATA. TRADITIONAL MODELING APPROACHES REQUIRE QUANTITATIVE DATA AND DETAILED KNOWLEDGE OF THE ECOLOGICAL SYSTEM. ALTHOUGH SUCH DATA MAY BE AVAILABLE FOR SMALL CONTROLLED SYSTEMS SUCHAS THE LABORATORY MICROCOSM, IN MOST CASES SUFFICIENT INFORMATION IS NOT AVAILABLE FOR LARGE NATURAL SYSTEMS. QU ...

THE OBJECT OF THIS PROPOSED RESEARCH IS TO PRODUCE MORE RELIABLE ESTIMATES OF EXTREME WINDS IN THE UNITED STATES BY SEPARATELY ANALYZING WINDS DUE TO THUNDERSTORMS AND LARGE SCALE EXTRATROPICAL STORMS. THE PRESENT STATE OF THE ART METHODS FOR ESTIMATING DESIGN WIND SPEEDS IN NON-HURRICANE REGIONS OF THE UNITED STATES DO NOT DISTINGUISH BETWEEN WINDS ORIGINATING FROM THE LARGE SCALE EXTRATROPICAL P ...

WE PROPOSE TO DEVELOP A THIN-FILM INTEGRATED CAPACITOR STRUCTURE THAT INCORPORATES AN INSULATOR WITH A VERY HIGH DIELECTRIC CONSTANT. THIS CAN HAVE IMPORTANT APPLICATION TOHIGH-DENSITY COMPUTER MEMORY CHIPS WITH ELEMENTS ON THE MICRON AND SUBMICRON SCALE. IN ITS RUTILE CRYSTALLINE FORM,TIO2 EXHIBITS A DIELECTRIC CONSTANT GREATER THAN 100, WHICH CORRESPONDS TO A CAPACITANCE OF I UF/CM(2) FOR A 100 ...

ENGINEERING APPLICATIONS OF LAYERED COMPOSITES OR LAMINATES ARE VERY IMPORTANT AND DIVERSE. INTERLAYER CRACKSOR DELAMINATIONS IS ONE OF THE MAJOR REASONS OF COMPOSITE STRUCTURAL FAILURE. DELAMINATIONS MAY CAUSE CONSIDERABLE DEGRADATION OF STIFFNESS AND STRENGTH OF COMPOSITE STRUCTURES. THIS PHENOMENON HAS RECEIVED CONSIDERABLE ATTENTION IN RECENT YEARS. BUT, TO ACHIEVE A DEEPER INSIGHT INTO THE PR ...

DIMENSION TECHNOLOGIES INC. ("DTI") PROPOSES TO RESEARCH AND DEVELOP A TECHNOLOGY THAT WILL ALLOW THE MANUFACTURE OF VERY HIGH RESOLUTION AUTOSTEREOSCOPIC (3D) DISPLAYS FOR ADVANCED COMPUTER APPLICATIONS. THIS INNOVATIVE TECHNOLOGY WILL PROVIDE THE SCIENTIFIC COMMUNITY A TRUE 3D ALTERNATIVE TO CURRENT 3D AND 2D IMAGING SYSTEMS. DTI HAS DEVISED A METHOD THAT ALLOWS THE DISPLAY OF IMAGES WITH A RESO ...

CAUSTIC IS PRODUCED IN THE USA TO THE EXTENT OF 36,500T/DAY, MAINLY BY THE ELECTROLYSIS OF BRINE. THE ANODEPRODUCT, CHLORINE, IS UNDER CONSIDERABLE PRESSURE FOR ENVIRONMENTAL REASONS. FOR EXAMPLE, SALES ARE DECLINING TO THE PULP AND PAPER INDUSTRY BECAUSE OF TRACES OF DIOXIN FORMED IN PAPER PRODUCTS. ALSO, OZONE DESTROYING CARBON COMPOUNDS LIKE CHLOROFLUOROCARBONS AND METHYLCHLOROFORM ARE VERY LIK ...

HAZARDOUS, TOXIC ORGANICS ARE PRESENT IN THE WASTE STREAMS OF MANY INDUSTRIES SUCH AS TEXTILE, PETROLEUM REFINING, PULP AND PAPER AND ORGANIC CHEMICAL MANUFACTURING. THE ENVIRONMENTAL PROTECTION AGENCY (EPA) HAS ISSUED STRICTER REGULATIONS REGARDING WATER POLLUTION, REQUIRING INDUSTRY TOFIND NEW METHODS FOR ELIMINATION OF THE ORGANICS NOW PRESENT IN THEIR WASTE STREAMS. PRESENT METHODS WHICH ARE A ...
