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 ...

Improving particulate matter (PM) analysis technology for on-vehicle measurements remains a significant challenge. The requirement for accurate and highly precise real-time measurement, capable of on-vehicle applications, is rapidly increasing. Expanding demand for compliance measurements, and assessing and evaluating engine performance development and emergent exhaust aftertreatment technologie ...

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 ...

Finishes Unlimited, Inc., produces baking enamels for general purpose original equipment manufacturers who make sundry metal products such as lockers, tool boxes, compressors, folding chairs, storage racks, etc. Although it is a small company, Finishes Unlimited, Inc., has been among the leaders in one type of environmentally friendly coatings (i.e., waterborne bake enamels). In 1993, it became ...

Under the Clean Air Act, the U.S. Environmental Protection Agency has identified 21 Mobile Air Source Toxics. Because no truly portable, real-time method exists for the determination of these compounds in engine exhaust, there is an opportunity for the application of portable miniature mass spectrometry coupled with proton transfer reaction ionization (PTR-MMS) to such an analysis. The MMS utili ...

Ambient particulate matter (PM) mass exposure is determined by collecting the PM on a sample filter over a period of 24 hours. Because the composition of ambient PM is constantly changing, the PM mass measured using the reference method may not be representative of the PM levels in the atmosphere, primarily due to the loss of collected semi-volatile material that is present in the atmosphere duri ...

VEETech, in conjunction with Lehigh University, will synthesize and test novel hybrid sorbents (HIXs) for the removal of arsenic from drinking water. The HIXs are polymeric/inorganic hybrid sorbents in which cation exchange resin beads are irreversibly and uniformly coated with hydrated ferric oxide (HFO) materials. The HIXs are expected to demonstrate superior selectivity and capacity over othe ...
