A NEW TECHNIQUE IS PROPOSED FOR THE PREPARATION OF METAL-SUPPORTED METAL (MSM) CATALYSTS. THE KEY FEATURE OF THIS TECHNIQUE INVOLVES THE PREPARATION OF A THIN LAYER OF POROUS METAL ON TOP OF A METAL SUBSTRATE SUCH THAT THE POROUS METAL SURFACE IS AN INTEGRAL PART OF THE METAL SUPPORT. SUBSEQUENT INTEGRATION OF PT AND RH ON THE POROUS METAL SURFACE WILL PRODUCE THE MSM CATALYST. THIS CATALYST IS US ...

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 ...

Ammonia has an important role in the chemistry of the atmospheric environment and air quality. Ammonia emissions are a major environmental concern, yet they remain poorly quantified. There is a need for a sensitive ammonia instrument to monitor emissions and evaluate their effects on the local and regional environments. An instrument capable of continuous monitoring is required to understand diurn ...

Infrared (IR) imaging is the best method for detecting leaks of pollutant gases, but current technology based on cooled IR imagers is far too expensive ($75,000 to $150,000) for everyday field use by those who need it to meet regulatory limits¿electric and petrochemical utilities, manufacturing plants, and businesses such as supermarkets. Agiltron will demonstrate a new class of IR imager instrum ...

The use of nanoparticles has increased in manufacturing, industry, and commercial products over the past two decades. As a result, governmental agencies, industry, and academia worldwide have formed advisory groups to evaluate exposure and toxicity issues surrounding the potential adverse effects of nanomaterials on human health. However, assessing the potential effects of nanoparticles on human h ...

This proposed project is for the experimental operation and performance review of a pilot-scale anaerobic digester and effluent treatment system for small dairy farms. This would be one of the first digesters built on a dairy farm with a herd size of 50-100 heads. Although digesters are considered to be a valuable addition to a farms manure management strategy, several sources have stated that far ...

THE CONTROL OF VOLATILE ORGANIC CONTAMINANT (VOC) EMISSIONS FROM INDUSTRIAL PROCESSES AND FUEL SOURCES IS AN IMPORTANT ENVIRONMENTAL PROBLEM. STRINGENT REGULATIONS HAVE BEEN ENACTED THAT WILL LIMIT SUCH EMISSIONS, HEIGHTENING THE NEED FOR SMALL, SIMPLE UNITS THAT CAN RECOVER VOCS AND RETURN THEM AS REUSABLE COMPOUNDS. CURRENT VOC-REMOVAL TECHNOLOGIES, SUCH AS INCINERATION, CARBON ADSORPTION, AND C ...

This proposed project directly addresses an U.S. Environmental Protection Agency (EPA) calling for improved detection and measurement techniques including screening kits for algal neurotoxins (especially cyanobacterial anatoxin) and cytotoxins in drinking water systems. Bloom-forming cyanobacteria have been observed in water bodies, including drinking water reservoirs all over the world. Several ...

NUMEROUS INDUSTRIAL PLANTS ARE SOURCES OF LOW CONCENTRATIONS OF VOLATILE ORGANIC COMPOUNDS (VOC) WHICH ARE EMITTED INTO THE AIR, SOMETIMES IN HIGH FLOWS OF OFFGAS. SOME OF THE OFFGAS STREAMS MAY ALSO CONTAIN FINE PARTICULATE MATTER FROM 10 MICRONS TO THE SUBMICRON SIZE RANGE. THE VOC MAY CONDENSE ON THE FINE PARTICULATE MATTER WHICH, DUE TO ITS SIZE, CAN LODGE DEEP WITHIN THE LUNGS. MOST INDUSTRIA ...

DIESEL ENGINES PLAY AN IMPORTANT ROLE IN THE UNITED STATES ECONOMY FOR POWER GENERATION AND TRANSPORTATION. HOWEVER, NOX AND SOOT EMISSIONS FROM BOTH STATIONARY AND MOBILE DIESEL ENGINES ARE A MAJOR CONTRIBUTOR TO AIR POLLUTION. MANY ENGINE MODIFICATIONS AND EXHAUST-AFTER-TREATMENT DEVICES HAVE BEEN PROPOSED AND TESTED TO REDUCE THE NOX AND SOOT EMISSIONS FORM DIESEL EXHAUSTS. SIMPLE TECHNIQUES FO ...
