In the 2002 Small Business Innovation Research Solicitation, the U.S. Environmental Protection Agency explicitly expressed interest in instruments that can accurately and reliably measure particulate emissions from vehicles. The availability of suitable instruments for measuring particulate emissions from engines and vehicles will benefit two broad categories of users: (1) it will directly help ...

Contaminated groundwater containing trichloroethylene and similar halogenated hydrocarbons poses a large-scale environmental challenge. Existing treatment methods are imperfect in that they are slow, expensive, fail to treat the full spectrum of groundwater contaminants, and sometimes produce even more toxic partially chlorinated chemical intermediaries. In the past decade, techniques have emerg ...

A simulation tool is proposed to model and simulate the wind fields, turbulence fields, and the unsteady dispersion of NCBR substances in urban areas on the building to city blocks scale. This Computational Fluid Dynamics (CFD)-based approach has beenshown to accurately simulate the urban wind and turbulence fields with minimal approximations, and has been demonstrated by modeling the flow fields ...

The proposed research will demonstrate a diesel particulate matter (PM) exhaust aftertreatment technology that exceeds the performance of the catalyzed diesel particle filter (CDPF) technologies currently being tested by the U.S. Environmental Protection Agency (EPA). Using a unique microwave-sensitive silicon carbide fiber filter cartridge, Industrial Ceramic Solutions¿ microwave-regenerated pa ...

An important approach to limiting the pollution of our Nation¿s natural waters and drinking water supply is the development of field-deployable monitors to detect the presence of pollutants in ground and surface waters. Monitors can alert regulators to the presence of dangerous contaminants before they spread more widely through the ecosystem, thus protecting human health and the environment. I ...

Treatment of water contaminated with volatile organic compounds (VOCs) is a major problem for the U.S. chemical industry. Currently, VOCs are removed from moderately contaminated wastewater streams by processes such as steam stripping, and wastewaters containing low levels of VOCs are treated by air stripping combined with a carbon adsorption off-gas treatment system. Membrane Technology and Res ...

Electronic waste (e-waste) is one of the most rapidly growing waste problems worldwide and has reached crisis proportions. The crisis relates not only to quantity, but also to the toxic nature of e-waste. Vast amounts of toxic materials such as lead, beryllium, mercury, cadmium, and brominated flame retardants are contained within the growing mountains of e-waste around the world. The United St ...
