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 ...

Phosphorous and nitrogen are valuable nutrients found in wastewater. The flow of phosphorous from rocks to the natural waterway has increased in recent years, due in large part to agricultural production. In addition to being a nutrient, phosphorous is a contaminant in aquatic environments that leads to the formation of organic material and algae. Recovery of phosphorous from wastewater will ensur ...

Suspended ceiling tiles are widely used in commercial and residential construction because they offer flexibility and easy access to utilities. Most of the available tiles absorb water, resulting in sagging, staining, and mold/mildew growth. They also contain potentially hazardous chemicals and release airborne fibers when broken or cut. Existing tiles are not durable, requiring frequent replaceme ...

TIAX has developed a technology that meets the EPA' s need for decontamination of biological material in railway and subway cars. It provides simultaneous encapsulation and killing of biological contaminants with the added capability for decontamination of chemical and radiological hazards. Current technologies are manpower intensive involving separate steps for site preparation; decontamination; ...

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 ...

A uniquely qualified team consisting of ETSVP-JV, a small business joint venture, and subcontractor RTI International, brings together all of the skills and experience needed for the development and testing of innovative nanomaterial filters. For this Phase I SBIR project, we propose to develop a dual-stage nanoporous filter media for controlling PM2.5 and volatile organic compounds (VOCs). Materi ...

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 ...

Particulate matter (PM) and volatile organic compound (VOC) emissions from commercial cooking establishments are a subject of increasing concern around the globe. Although increased awareness of the health hazards of respirable particulates and VOCs has prompted the development of new technologies to reduce emissions from restaurants, current technologies do not remove all hazardous air pollutants ...
