AIR TOXIC METALS AND THEIR COMPOUNDS ARE PRODUCED FROM THE COMBUSTION OF FOSSIL-FUELS. THE COMBUSTION OF COAL AND FUEL OIL REPRESENTS AN EXTREMELY LARGE CATEGORY OF SOURCE EMISSIONS. RESEARCH IS PROPOSED THAT WILL PROVIDE A MEANS FOR REMOVING THE VOLATILE METAL CONTENT OF FLUE GAS GENERATED FROM POWER AND STEAM GENERATING PLANTS USING ZEOLITIC OR CARBONACEOUS ADSORBENTS. A LABORATORY-SCALE FIXTURE ...

This proposal describes the development of an instrument based on laser-induced breakdown spectroscopy (LIBS) for the detection of lead in paint and soil that will have both military and commercial applications. The Phase I instrument will be similar to multi-species, portable LIBS instruments built by Dr. David Cremers at Los Alamos National Laboratory that utilize a spectrograph/charge coupled ...

This research project will develop a unique, high-power, 30 amp hour (Ah) rechargeable battery for a variety of commercial and military applications. The performance characteristics of this technology have produced the highest specific peak power of any known battery technology, producing power levels in excess of 5000 Watts/kilogram (W/kg) and 16,000 Watts/liter (W/1). In addition, this unique Th ...

ION EXCHANGE IS AN ATTRACTIVE TECHNOLOGY FOR REMOVAL OF HEAVY METALS FROM WATER AND WASTEWATERS, BUT IT IS COMMONLY FOUND TO BE UNECONOMICAL DUE TO THE HIGH COST OF CHEMICALS AND DISPOSAL OF THE BRINES OR SECONDARY WASTES GENERATED. SEVERAL IMPROVEMENTS TO THIS TECHNOLOGY ARE PROPOSED TO ALLOW ION EXCHANGE TO BE MORE WIDELY APPLIED TO THE REMOVAL OF TOXIC HEAVY METALS AT SUPERFUND SITES AND IN OTH ...

THE FLUOROCARBON INDUSTRY IN THE UNITED STATES CURRENTLY GENERATES OVER 1,200,000 POUNDS OF SPENT ANTIMONY FLUOROCARBON CATALYST ANNUALLY IN PRODUCING 1,190 MILLION POUNDS OF FLUOROCARBONS (CFCS, HCFCS, HFCS). THIS SPENT CATALYST IS A MIXTURE OF HALOGENATED ORGANIC COMPOUNDS (HOCS), ANTIMONY, AND ARSENIC HALIDES. IT IS EXTREMELY HAZARDOUS, TOXIC, AND CORROSIVE. IT CONTAINS AT LEAST EIGHT LISTED "C ...

Replacements for the halocarbons banned by the Montreal Protocol will be producedby technologies which generate spent catalysts as a waste byproduct. These spentcatalysts contain tin, a valuable metal resource, in a matrix that willundoubtedly be classified as hazardous with regard to its disposal.Chemical & Metal Industries, Inc., proposed in this Phase I effort to investigatetwo alternative tec ...

N/A

THIS EFFORT IS TO DETERMINE THE DESIGN OF A DIODE-PUMPED SOLID-STATE 2 UM COHERENT LASER RADAR FOR THE HIGH SPATIAL AND TEMPORAL RESOLUTION MEASUREMENT OF WIND VELOCITY AND WATER VAPOR CONCENTRATIONS IN THE ATMOSPHERIC BOUNDARY LAYER. A DETAILED COMPUTER SIMULATION OF THE COHERENT LASER RADAR WIND AND DIAL MEASUREMENT PROCESS WILL BE USED TO DETERMINE SYSTEM DESIGN PARAMETERS. A PERFORMANCE TRADE ...

Previous measurements using two micron solid-state lidar systems and computer simulation of lidar performance demonstrate that an eyesafe, low-pulse-energy (1 - 10 mJ/pulse), small aperture (~10cm) lidar will be capable of highly accurate high spatial resolution wind velocity measurements to ranges of 2-10 km in the atmospheric boundary layer. High-spatial resolution 3-D coverage for several km a ...
