Oxides of nitrogen, or NOx, are common air pollutants in congested urban areas. NOx contributes to a variety of environmental problems, including ground-level ozone (smog), acid rain, and visibility impairment. NOx emissions are generated by motor vehicles, industrial facilities, and electric power plants. The Clean Air Act Amendments of 1990 required that stationary sources, such as power plan ...

In 2011, there were 60,000 dairy farms in the US. Of there, 56,600 had herds of fewer than 500 animals. Currently, manure digester installations are only considered economical for herds of at least 500 animals. There require turbine or diesel generator sets of 100 Kilowatt size and larger. The need exists for a smaller waste to energy conversion approach for implementation on small farms were ...

This project will address the feasibility of an ambient temperature chloroaluminate ionic liquid as a medium for efficient electroplating of high-quality aluminum. The chloroaluminate, composed of a mixture of aluminum chloride and an organic chloride salt, is liquid at room temperature. These media promise highly effective plating of crystalline, nondendritic, nonporous aluminum. This process ...

Arsenic contamination in drinking water is a severe health risk to populations throughout the world, including the United States. In recognition of this threat, the U.S. Environmental Protection Agency (EPA) recently lowered its water standard for arsenic from 50 ppb to 10 ppb. This change is expected to impact 10 percent of U.S. community drinking water systems. The operators of small water sy ...

One of the program areas of interest to the U.S. Environmental Protection Agency (EPA) is the development of rapid, non-invasive monitors to detect exposure to toxic air pollutants at trace (ppt) levels. Of the 356 chemicals listed on the Chemical Emergency Preparedness and Prevention Office¿s List of Extremely Hazardous Substances (Section 302 of the Emergency Planning and Community Right-To-Kn ...

The release of chemical and biological agents on a large scale urban environment would be devastating. The amount of waste generated during such an event would be comparable to a tornado ripping through a town. Building materials, furniture, office materials, building insulation, wood structures could become contaminated to a level that they could not be decontaminated without their destruction. ...

In this program, we will develop a breakthrough technology that will enable wafer-scale epitaxial lift-off (ELO) of GaN power device heterostructures from low-dislocation-density bulk GaN substrates. This technology will be used to provide a low-cost vertical junction field effect transistors (VJFETs) with high breakdown voltage (greater than 1,200 V) and high current capability (greater than 100 ...

The U.S. Environmental Protection Agency (EPA) has announced its intention to regulate mercury emissions from coal-fired power plants because of mercury¿s impact on the health and development of young children and fetuses. The estimated cost of controlling mercury emissions from power plants runs from $2 to $5 billion annually, with a significant fraction of the total dedicated to activated carb ...

A team of EP Purification and the University of Illinois engineer and chemists is pursuing the commercialization of low cost microchannel plasma modules capable of efficiently producing ozone for water treatment. The conservation of water resources for human consumption is a growing national priority. Contamination of ground municipal water by animal manure, fertilizer and pharmaceuticals, for e ...
