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 ...

A team at EP Purification has performed research for the development and commercialization of low-cost microchannel plasma reactor modules capable of efficiently producing ozone for water treatment and other environmental applications in a slim form factor and size. The conservation of water resources for human consumption is a growing national priority. Ozone is a unique purification agent as it ...

Plastics and petroleum-based foams are a conventional solution for the material needs of many industries. Today these non-biodegradable, fossil fuel derived products compose 13 percent of all municipal solid waste streams, as opposed to 1 percent in 1960. This waste stream is associated with a number of environmental concerns, including greenhouse gas generation from incineration, as well as land ...

This project focuses on dissolution and destruction of adhered or trapped target compounds, such as pesticides on wetted porous surfaces (e.g., pipe walls). Our innovative treatment approach is based on simultaneous: (1) desorption from the pipe wall, and (2) oxidation via radical formation. OxyZone-C®, a proprietary reactive agent developed by our team, combines highly effective cyclodextrin­fa ...

Presently, there are no U.S. manufacturers for producing dimethyl carbonate (DMC), an environmentally benign and nonflammable solvent used in numerous applications. This strategically important solvent is used in numerous products, ranging from batteries to plastics, with most production occurring in China. DMC is a favored solvent for lithium ion batters due to its low volatility and nonflammable ...

A variety of inorganic and organic contaminants originating from municipal, agricultural and industrial wastewater sources are being found with increasing frequency in the Nation’s natural and drinking water supplies. These “emerging contaminants” include pharmaceuticals, antibiotics, steroids, hormones, flame retardants, perfluorinated compounds, personal care products, and herbicides and p ...

NEI Corporation proposes to develop a new and sustainable aqueous electrolyte-based lithium-ion (Li-ion) battery system that is capable of delivering high energy density, comparable to state-of-the-art Li-ion batteries. Almost all commercial Li-ion batteries use an organic electrolyte, which is flammable and has been a concern particularly in large format Li-ion batteries. In addition, there are t ...

As the number of mobile source emissions in the United States increases, it is necessary to further reduce the emission of CO, NOx, and hydrocarbons from such sources to provide safe air quality, especially in urban environments. Significant reductions in pollution emissions can be achieved using advanced engine controls based on real-time measurements of CO, NOx, and hydrocarbon concentrations i ...

A number of very high-volume liquid chemicals form azeotropes with water and can be dehydrated to required purity levels only through the use of entrainers or drying agents. The handling and disposal of these additional chemicals present significant environmental risks. Recently, membrane pervaporation using both polymeric and inorganic membrane modules has been commercialized as a method to deh ...

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 ...
