Abstract:In High Energy Lasers (HEL) a large percentage of the laser energy is wasted typically by switching onto beam dumps. Some of this wasted energy could be utilized to synthesize exotic materials which have useful commercial applications. In order to utilize this wasted energy to synthesize new and… more
Abstract:THE COMBUSTION OF COAL INTRODUCES HAZARDOUS EMISSION PRODUCTS, INCLUDING RESPIRABLE PARTICLES THAT ARE 10UM IN DIAMETER. THE REMOVAL OF THESE PARTICLES FROM THE COMBUSTION GAS STREAM IS DIFFICULT DUE TO THE HIGH TEMPERATURES AND CORROSIVE ENVIRONMENT. A CERAMIC FILTER HAS THE GRATST POTENTILA TO… more
Abstract:A novel and newly discovered C60 carbon material was found to exhibit unique electrochemical and physical properties. C60 and catalyzed C60 electrodes for hydrogen storage and supplies will be fabricated by vapor deposition and dry pressing. These electrodes will be fully characterized as hydrogen… more
Abstract:SILICON CARBIDE-SILICON CARBIDE (SIC/SIC) COMPOSITES HOLD SIGNIFICANT PROMISE FOR USE IN FUSION ENERGY SYSTEMS. EVEN GREATER OPPORTUNITY EXITS IF THE THERMAL CONDUCTIVITY OF THE CHEMICALLY VAPOR INFILTRATED (CVI) MARIX COULD BE IMPROVED. IT HAS BEEN SHOWN THAT THE THERMAL CONDUCTIVITY OF HOT PRESSED… more
Abstract:Fullerenes have become the most investigated/publicized scientific subject ever. In spite of this intense and the enormous commercial potential, the mechanism to the synthesis of the various fullerene structures of buckyballs, buckytubes and encapsulation within the cage structures has not been… more
Abstract:Boron carbide is the preferred ceramic material for armo applications; however, the production costs are very high which can be partially attributed to the high cost consodlidation techniques currently used. A novel fabrication technique is proposed that has very los associated costs and has the… more
Abstract:Fullerenes - the recently discovered pure carbon molecules - have a unique closed caged structure. This closed cage molecular structure bestows fullerene based solids with two important characteristics: first, an unprecedented lattice structure; and second, a molecular environment around fullerenes… more
Abstract:Fullerenes - the recently discovered closed cage forms of carbo - have unique and unprecedented pure carbon based thermal properties. Advanced materials based on fullerenes and fullerenes all by themselves are lightweight, long lived, environmentally benign and are materials that have very low… more
Abstract:While ceramic fiber reinforced titanium aluminide matrices composites are attractive due to their high specific strengths at high temperatures, one primary limitation is the lack of CTE match and chemical compatibility between the fiber and the matrix. The thermal mismatch and reaction zone is… more
Abstract:THE DEMONSTRATION THAT FULLERENES (BUCKYBALLS) CAN BE PRODUCED FROM A CARBON ARC HAS SPECTACULARLY OPENED A COMPLETELY NEW FIELD OF CARBON SCIENCE WHICH HAS POTENTIAL APPLICATIONS IN ALL SCIENTIFIC FIELDS OF CHEMISTRY, ELECTRONICS, PHYSICS, AND MEDICINE. HOWEVER, THE CONTINUED RESEARCH IN… more
Abstract:There is an acute need for novel broadband filters for unity vision equipment. This need can be satisfied with the recent discovery of a new pure form of carbon - fullerenes. Fullerenes have excellent nonlinear optical properties, show the best boradband limiting performance of all known material… more
Abstract:THERMAL MANAGEMENT IS ONE OF THE CRITICAL ASPECTS IN THE DESIGN OF THE 2- AND 3-DIMENSIONAL MULTICHIP MODULES (MCMS) TO ENSURE RELIABILITY AT INCREASED FUNCTIONAL DENSITIES IN ELECTRONIC DEVICES. DIAMOND HAS THE HIGHEST KNOWN THERMAL CONDUCTIVITY AND YET IS AN ELECTRICAL INSULATOR. HIGH QUALITY… more
Abstract:THERE IS A GROWING MARKET IN THE POWDER METALLURGY INDUSTRY FOR INTERMETALLIC POWDER WITH FINE PARTICLE SIZE AND GOOD COMPOSITIONAL CONTROL. A PROCESS TERMED PLASMA INITIATED SELF PROPAGATING HIGH TEMPERATURE SYNTHESIS (PSHS) IS PRESENTLY BEING DEVELOPED TO MEET THE GROWING DEMAND FOR SUCH POWDERS.… more
Abstract: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,… more

There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
