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 ...

Solvents are valuable processing tools in the chemical and related industries used to enhance mass transfer, heat transfer and processing aids not used in the final product. Solvents are very valuable but cause significant problems with volatility and associated emissions. Manufacturing processes that utilize green technology or solvents for process improvement and reduced emissions are very desir ...

Environmental Fuel Research, LLC, proposes to commercialize a grease trap waste to biofuel process based on process research from Drexel University. Grease trap waste is dirty and low-value material produced by the food service industry that is high in lipids that can be converted to biodiesel. The quantity of grease trap waste in the United States could produce one-half billion gallons of biodies ...

It is well known that many chemicals may disturb the endocrine system. These endocrine-disrupting chemicals (EDCs) can cause adverse effects on human health and wildlife. In 1996, Congress directed the U.S. Environmental Protection Agency (EPA) to develop the Endocrine Disruptor Screening Program (EDSP) to determine if chemicals used in commerce may have hormonal effects in humans. There are mo ...

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 ...

Conventional volatile organic compound (VOC) recovery membranes (silicone rubber) preferentially transport organics over air. Although this silicone rubber has shown some success, it is not appropriate upstream of catalytic oxidation. Catalytic oxidation requires modest increases in VOC concentration at pressure to maintain performance. This is best achieved by using a reverse separation membra ...

Diesel generator sets (gen-sets) are used routinely to supply electrical power. Hospitals, businesses, and small communities use gen-sets to help reduce costs by load leveling and provide emergency power during blackouts (either scheduled or unscheduled). Recent power outages in California have led to large increases in the purchase of gen-sets, primarily for providing emergency power. In addit ...

This research project aims to modify an environmentally and occupationally favorable novel method to remove lead-based paint from steel for use on nonconductive substrates such as wood, cement, brick, and cinder block. If successful, a convenient, dust-free method will be available for safe indoor and outdoor site remediation involving lead hazards and waste. Minimal occupational hazards and rec ...
