THE EMISSION OF HALOGEN CONTAINING POLLUTANTS FROM A VARIETY OF POWER GENERATING, WASTE PROCESSING, CHEMICAL PRODUCTION, AND SOLVENT USING INDUSTRIES IS AN ENVIRONMENTAL CONCERN OF MAJOR SIGNIFICANCE. INORGANIC HALOGEN SPECIES, INCLUDING HYDROGEN CHLORIDE AND HYDROGEN FLUORIDE, REPRESENT MAJOR POTENTIAL HEALTH THREATS TO BOTH HUMAN, ANIMAL, AND PLANT COMMUNITIES. ORGANIC HALOGENATED COMPOUNDS (HOC ...

DOE IS DEVELOPING A NUMBER OF ADVANCED COAL CONVERSION PROCESSES THAT OPERATE AT HIGH TEMPERATURES AND PRESSURES. THE COAL THAT IS CONVERTED IN THESE PROCESSES PRODUCES A VARIETY OF CONTAMINANTS. THESE CONTAMINANTS NEED TO BE REMOVED FROM THE HOTGAS STREAM IN ORDER FOR THEPROCESS TO OPERATE AT MAXIMUM EFFICIENCY. VOLATILE METALS CONSTITUTE A FAMILY OF COMPOUNDS FOUND IN THESE GAS STREAMS THAT WILL ...

THE CLEAN AIR ACT (CAA) AMENDMENTS OF 1990 DEFINED 189 INDIVIDUAL HAZARDOUS AIR POLLUTANTS WHICH MUST BE MONITORED AND CONTROLLED. THIS LIST OF AIR TOXICS CONTAINS 11 INORGANIC (METAL) CONSTITUENTS AND INCLUDES ARSENIC, BERYLIUM, MERCURY, ANTIMONY, CADMIUM, CHROMIUM, COBALT, LEAD, MANGANESE, NICKEL, AND SELENIUM. CURRENT TECHNOLOGY FOR MEASURING THESE COMPONENTS IN EMISSION STREAMS DEPENDS UPON EX ...

MOUTHSTICKS OR ORTHODONTIC ORTHOSES ARE WIDELY USED BY PEOPLE WITH SPINAL CHORD INJURIES OR SIMILAR DISABILITIES TO INCREASE CONTROL OVER THEIR ENVIRONMENT. PEOPLE WITH THE ADDITIONAL LIMITATION OF LITTLE OR NO ANTERIOR/POSTERIOR HEAD MOTION MAY BENEFIT FROM AN EXTENDIBLE MOUTHSTICK. HOWEVER, COMMERCIAL EXTENDIBLE MOUTHSTICKS SUFFER IN THAT THEIR ACTION IS OFTEN SLOW, EXTENDIBILITY IS LIMITED, OR ...

REMOVAL OF TOXIC METALS FROM WASTEWATER STREAMS HAS BECOME A PROBLEM OF INCREASING NATIONAL IMPORTANCE, AS A RESULT OF INCREASING CONCERN FOR OUR ENVIRONMENT, AND INCREASINGLY STRINGENT WASTE DISPOSAL REGULATIONS. CHROMATOCHEM, INC., HAS DEVELOPED AN ECONOMICAL AND EFFECTIVE NEW TECHNOLOGY FOR THE REMOVAL OF LOW LEVELS OF TOXIC METAL IONS FROM WASTEWATER STREAMS, USING SOLID PHASE EXTRACTION (SPE) ...

OVER THE YEARS, THERE HAVE BEEN A NUMBER OF ADVANCED COAL COMBUSTIONTECHNOLOGIES WHICH HAVE ATTEMPTED TO UTILIZE COAL-WATER SLURRY (CWS) AS FUEL. TYPICALLY, THE GOALS FOR DEVELOPMENT OF CWS FUEL TECHNOLOGIES HAVE BEEN AIMED AT UTILIZATION OF RECOVERED FINE COAL, REPLACEMENT OF NATURAL GAS OR PETROLEUM, OR ELIMINATION OF THE HANDLING AND DEWATERING PROBLEMS ASSOCIATED WITH HIGHLY BENEFICATED FINE C ...

FRICTIONAL LOSSES ACCOUNT FOR A LARGE PERCENTAGE OF THE TOTAL MECHANICAL POWER LOSS IN ENGINES. THEREFORE, SLIDING SURFACES WITH LOW FRICTION, HIGH WEAR RESISTANCE, AND LONG LIFETIMES REPRESENT AN ENABLING TECHNOLOGY FOR FUTURE TRANSPORTATION SYSTEMS. THIS PROJECT WILL INVESTIGATE AN ENTIRELY NEW CLASS OF CERAMIC-MATRIX-COMPOSITE (CMC) RINGS AND CYLINDERS, WITH A GRADED DISTRIBUTION OF CERAMIC COM ...
