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 ...

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 ...

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 ...

THE CONTROL OF NITROAROMATIC AIR POLLUTANTS BY BIOSCRUBBING WILL BE EVALUATED AS TO THEIR FEASIBILITY AND EFFICIENCY IN BENCH-SCALE EXPERIMENTS. A MICROBIAL CONSORTIUM ENRICHED ON SELECTED NITROAROMATIC AIR POLLUTANTS SUCH AS NITROBENZENE OR NITROTOLUENE WILL BE IMMOBILIZED ON A POROUS SOLID MATRIX PACKED INTO A SCRUBBING COLUMN. MEASURED VOLUMES OF AIR, CONTAINING KNOWN CONCENTRATIONS OF THE NITR ...

DURING THE MID-EIGHTIES, APPROXIMATELY THREE MILLION CHILDRED BETWEEN SIX MONTHS AND FIVE YEARS OLD HAD POISONOUS BLOOD LEAD CONCENTRATIONS DUE TO PAINT. THERE IS RISK FOR ADULTS IN THE PAINT, AUTOMOBILE MANUFACTURING, AND CERAMIC INDUSTRIES. THE NATION COULD SUBSTANTIALLY REDUCE THE INCIDENCE OF LEAD POISONING IF ONE WERE ABLE TO MEASURE LEAD USING A INEXPENSIVE, PORTABLE DEVICE. CURRENT LEAD MEA ...

A HIGH EFFICIENCY ACTIVATED CARBON GRANULE WILL BE DEVELOPED FOR DRINKING WATER TREATMENT. THE FOUNDATION FOR THIS HIGH EFFICIENCY GRANULE IS A SUPERACTIVATED CARBON WITH A BET SURFACE AREA IN EXCESS OF 3000 M(2)/GM USING THE STANDARD PROCEDURE BY BRUNAUER, EMMETT, AND TELLER, AND AN IODINE NUMBER GREATER THAN 3000 MG/G. TWO GRANULATIN TECHNOLOGIES WILL BE EXPLORED: SPHERICAL AGGLOMERATION AND EXT ...
