Electronic power conversion systems introduce major cost and reliability issues in most distributed energy resources and energy storage systems. This project will develop a power conversion system based on an emerging wide-bandgap, SiC-based semiconductor technology. This system will be capable of operating at high power densities, high temperatures, and high frequencies, and will provide advant ...

Organic matter is a major constituent of airborne particles, comprising 20-50% of their mass. Identification of its components is critical for tracing sources, elucidating transformation and formation processes, assessing affects on human health, and assessing affects on global climate. Therefore, in situ, high-time-resolution comprehensive measurements of organic aerosol speciation are required. ...

The objectives of this research are to enhance and accelerate the in situ bioconversion of sequestered carbon dioxide, a greenhouse gas, into methane in the presence of hydrogen-rich coal macerals and paraffin. Methanogens require a source of hydrogen and an electron acceptor such as carbon dioxide in order to generate methane. The abundance of hydrogen coupled with sequestered carbon dioxide in ...

The overall goal of this research work is to design, build and evaluate high performance above-knee prosthetic systems suitable for military specific maneuvers. Existing above-knee prostheses are limited by the lack of compact energy sources, actuators, power regeneration methods, and control methods for active knee actuation. This proposal seeks to improve the dynamic performance of above-the-k ...

The direct versus heterodyne detection tradeoffs made in the Phase I program clearly showed that direct detection is strongly favored over heterodyne detection based on sensor performance analysis; assessment of laser and electronics hardware; and conside

Highly fluorinated, nanoscaled polymers were developed in a Phase I program (Contract No. W81XWH-04-C-0132) as an oxygen-carrying treatment for hemorrhagic shock in battlefield environments. These were highly soluble in water and buffered electrolyte solution (up to roughly 50% weight/volume) and were thermally stable up to 167 °C. Mixing the polymers with dilute canine blood significantly enhanc ...

A unique, wireless, body-worn system to establish on-body collection and intra-squad communication of physiologic and geo-position information is essential to the reduction of soldier heat-injuries, enables advanced physiologic research and provides a mea

At thousands of sites across the U.S., groundwater and soils are contaminated with hazardous chemicals, metals, and radioactive contaminants. At both private and government sites, including DOE, there is strong interest in reducing the costs of cleanup and long-term monitoring. Many advances have recently occurred in the field of hydrogeophysics, where geophysical data are used to estimate hydrog ...

Physical performance biomarkers are substances produced by the body when required to perform work for extended periods. We have shown, during Phase I, that fatigue is linked to alteration in the abundance of these substances in human saliva. Our goal is

The efficient and profitable operation of coal-fired power plants requires higher steam temperatures and pressures, necessitating the use of advanced alloys. A major concern in using these advanced materials is their poor corrosion and oxidation resistance in fossil energy environments. Therefore, protective coatings on the ferritic and austenitic steels used in these coal-fired environments are ...
