AN INNOVATIVE ALTERNATIVE FOR PREPARING SILICON CARBIDE (SIC)/SIC COMPOSITES INVOLVES THE DIMOX(TM) DIRECTED METAL OXIDATION APPROACH TO FORM A SIC MATRIX. IN THE DIRECTED METAL OXIDATION PROCESS A MOLTEN METAL IS OXIDIZED TO GROW AN OXIDATION REACTION PRODUCT INTO AN ADJACENT PREFORM OF REINFORCEMENT MATERIAL. ALTHOUGH THIS PROCESS IS CURRENTLY HIGHLY DEVELOPED FOR ALUMINIUM OXIDE MATRIX MATERIAL ...

RECENTLY THERE HAS BEEN A RAPIDLY GROWING INTEREST IN DENSITY FUNCTIONAL THEORY (DFT) AS A GENERAL PROCEDURE FOR PREDICTING PHYSICAL PROPERTIES OF MOLECULES. THIS IS RELATIVELY INEXPENSIVE COMPARED TO TRADITIONAL CORRELATED METHODS. FOR THE LARGEST MOLECULAR SYSTEMS WHOSE STUDY IS FEASIBLE BY THE CURRENT DFT PROGRAM (SEVERAL HUNDRED ATOMS), THE TREATMENT OF THE COULOMB INTERACTIONS, WITH ITS QUADR ...

GUARDRAIL TERMINALS ARE SOME OF THE MORE TROUBLESOME AND POTENTIALLY HAZARDOUS ROADSIDE APPURTENANCES. RECENTLY DEVELOPED TERMINAL CONCEPTS WHICH HAVE PASSED CURRENT CRASH TEST CRITERIA TEND TO BE EXPENSIVE AND MAY REQUIRE EXCESSIVE LENGTH OF NEED, FLARE-OUT SPACE AND ADDITIONAL FILL AND GRADING. THIS PHASE I SBIR PROPOSAL ADDRESSES THE DEVELOPMENT OF A MORE EFFICIENT ENERGY ABSORBING TERMINAL CON ...

IT IS CLEARLY RECOGNIZED BY THOSE ASSOCIATED WITH ENVIRONMENTAL RESTORATION THAT COAL-FIRED BOILER FLYASH IS A SIGNIFICANT CONTRIBUTOR TO THE INCREASING SHORTAGE OF LANDFILL AVAILABILITY. IN GENERAL, THE LANDFILL REQUIREMENTS FOR SOLID WASTE PRODUCTS ARE BECOMING A MAJOR ENVIRONMENTAL AND ECONOMIC ISSUE. THIS PROJECT ADDRESSES A MEANS OF MITIGTING A PART OF THE PROBLEM ASSOCIATED WITH THE DISPOSAL ...

60104 Asbestos abatement costs, associated with the DOE¿s national weapons¿ complex clean-up efforts, may amount to $300-500 million, while nationally, asbestos abatement may cost more than $100 billion over the next 25 years. Abatement methods have changed little in the past 20 years, and there is a need for a cheaper, faster, and safer abatement method. This project will design, buil ...

60311 There are economic and environmental justifications for replacing conventional distillation processes with simpler membrane separations in certain applications. However, at present, there are no commercial membranes able to withstand the aggressive conditions associated with important industrial chemicals, including hydrogen fluoride, hydrogen chloride, and ozone. Prototype, chemic ...

60395 Emissions of volatile organic compounds (VOC) from gasoline refueling facilities continue to be an energy, safety, and environmental issue. In such applications, it is desired to vent the air in the system and keep the VOC behind. This project will develop a reverse separation membrane (RSM) system that allows for rapid venting of air while retaining the gasoline in underground storag ...

60585 Fischer Tropsch (F-T) synthesis is a promising process for producing high quality, environmentally clean, diesel fuels. However, the separation of catalyst fines from the Fischer-Tropsch (F-T) reactor product stream has been a major impediment to applying the technology for the conversion of hydrocarbon resources such as coal and petroleum coke to clean burning fuels. This project w ...

60924 The development of affinity membranes has the potential to offer a quantum leap in membrane-based separation technology. Current polymeric membrane researchers modify surface functionality to offer a specific affinity; however, in the area of inorganic membranes, few similar activities exist. This project will develop an affinity inorganic membrane that can demonstrate separations ba ...
