THE PROPOSED PROJECT WILL DEMONSTRATE THE FEASIBILITY OF EMPLOYING ELECTRON TRAPPING (ET) MATERIALS WITH FIBER OPTICS FILAMENTS FOR USE AS MICROPROBE RADIATION DOSIMETERS.THE ET MATERIALS TM CAN BE INTERROGATED BY NEAR-INFRARED TO PRODUCE VISIBLE OUTPUT SCALABLE TO RADIATION DOSES AT THE FIBER TIP. PHASE I WILL ASSESS THE PERFORMANCE OF SUCH MATERIALS AS MICROPORBE RADIATION DETECTORS INTEGRATED W ...

THE THREE-WAY CATALYTIC CONVERTER IS THE MOST IMPORTANT DEVICE MAKING TODAY'S AUTOMOBILES COMPLY WITH EXISTING EMISSION LAWS. THE FIRST TWO OR THREE MILES IN A TYPICAL 22-MINUTE, 12-MILE COMUTE IN TODAY'S VEHICLES RESULT IN THE EMISSION OF HALF OF THE TOTAL NON-METHANE HYDROCARBONS, WHICH RESULT IN THE PRODUCTION OF URBAN SMOG, AS WELL AS HALF OF THE TOXIC CO EMISSIONS. THIS OCCURS BECAUSE THE CAT ...

IONICS RESEARCH INC. (IRI) HAS DETERMINED THAT UNCOATED CAPILLARY COLUMNS CAN BE USED TO CONCENTRATE ORGANICS FROM WATER. THE METHOD IS EXCEEDINGLY SIMPLE AND RAPID (10 MINUTES PER 100 ML), YET EFFECTIVE. IRI PLANS TO INVESTIGATE THE POTENTIAL OF THIS TECHNIQUE FOR THE DEVELOPMENT OF AN INSTRUMENT SUITABLE FOR THA NALYSIS OF ORGANICS AT THE PART-PER-TRILLION LEVEL IN WATER AND WASTEWATER. SUCH AN ...

THIS PROPOSAL IS CONCERNED WITH THE ECONOMIC REMOVAL OF HYDROGEN SULFIDE, A TOXIC MATERIAL, FROM SOUR NATURAL GAS AND PETROLEUM PRODUCTS. THE CURRENT STATUS OF H2S PROCESSING IS REVIEWED. THE CHEMISTRY OF SULFUR AND SULFIDE IN AQUEOUS SOLUTIONS AND PRELIMINARY WORK ALREADY CARRIED OUT IN THE CONTINUOUS ELECTROLYSIS OF H2S TO YIELD HYDROGEN AND SULFUR ARE BRIEFLYDISCUSSED. THE ESTIMATED ECONOMIC GA ...

Chlorinated hydrocarbons represent the most prevalent contaminants of groundwater in the country. When released in the subsurface, they tend to persist below the water table, and it can take decades or centuries before slow-moving groundwater completely dissolves accumulations of chlorinated solvent product. Analytical methods currently available for monitoring these compounds require extensive ...

Heavy metal species mobilized and released into the environment by technological activities tend to persist indefinitely, circulating and eventually accumulating throughout the food chain, posing a serious threat to the environment, animals, and humans. Typical industrial metal-containing discharges can be considered as point-source emissions, which in turn offer the possibility of feasible remed ...

Zebra mussels cause an estimated $5 billion in economic damages annually. They clog water intake pipes, damage water supplies, threaten native fish and aquatic species, and promote the mobilization of toxic materials into the food chain. Chlorination is presently the most common treatment for zebra mussels. However, chlorine causes many serious environmental risks, thus necessitating the develo ...

This Phase I project will develop a multianalyte biosensor field screening instrument (MBFI). The MBFI has the potential to reduce the annual cost of environmental analyses in the United States by more than $20 million and to reduce the analysis turnaround time from approximately 19 days to less than 15 minutes. The major barrier to the development of a biosensor instrument for environmental mea ...

AT MULTI-UNIT NUCLEAR GENRATING STATIONS, CONTROL ROOM OPERATORS ARE GENERALLY LICENSED TO OPERATE ALL SIMILAR UNITS. SIMULATOR TRAINING CONDUCTED AT THE LICENSEE TRAINING FACILITY OCCURS ON ONE SIMULATOR WHICH MAY NOT EXACTLY MIMIC ANY UNIT. INADEQUATE TRAINING ON UNIT-TO-UNIT AND UNIT-TO-SIMULATOR DIFFERENCES, IN CONJUNCTION WITH LIMITED PER-PERSON SIMULATOR TRAINING HOURS, CAN RESULT IN INCREAS ...
