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 ...

The objective of the proposed work is to determine whether Dioxide Materials' miniature C02 sensors have the potential to be adapted for autonomous measurement of ocean carbon. The existing sensors have many advantages for measurements of ocean carbon. They are much smaller and less costly than the existing sensors, work with much smaller gas samples, and use much less power. The sensors were d ...

This Phase I proposal determines the feasibility of growing multiple species of macroalgae in commercial marine aquafarm environments. Marine aquaculture is a logical outgrowth of successful wild harvest seaweed businesses over the last several years. Developing a marine aquaculture prototype will foster the science of sea farming. Extending growing seasons for multi-species would provide year ...

The goal of this project is to develop, implement, and experimentally validate a new Differential Global Navigation Satellite System (DGNSS) capable of providing sub-centimeter positioning accuracy for quasi-static scientific, mapping, and survey applications. The main feature of the proposed DGNSS solution is that it leverages GNSS reference data from existing NOAA's Continuously Operational Ref ...

his project involves the commercialization of the breast phantom designed by NIST and University of California, San Francisco (UCSF) for quantitative magnetic resonance imaging (MRI). The breast phantom consists of two independent phantoms, one focused on diffusion MRI measurements and the other focused on accurate measurements of fat and fibroglandular tissue properties. The proposed phantom is o ...

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 ...

Of the18,000 miles of pre-stressed concrete cylinder pipe (PCCP) within the drinking water transmission infrastructure laid between 1945 and 1996 in the United States, almost one-half, or 8,600 miles of pipe, is considered to be end-of-life infrastructure, awaiting funding for replacement. The American Society of Civil Engineers (ASCE) gave the United States a grade of D for its drinking water inf ...

Improving the quality and intensity of the x-ray beam is an important design goal for every synchrotron installation. Although small, the effects of vacuum windows on x-ray absorption and phase contrast cannot be neglected. Synchrotron x-rays have wavelengths on the order of one Angstrom (1 x 10-10m), the same order of magnitude as inter-atomic distances. These x-rays are used to study many differ ...

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 ...
