Perchlorate is a widely used component of solid fuel, missile and rocket propellants, explosives, and pyrotechnics. It has been shown to reduce iodide uptake into the thyroid gland. The U.S. Environmental Protection Agency (EPA) has found perchlorate contamination in 18 states and believes contamination may exist in as many as 39 states. In early January 2005, the National Academy of Science ...

Lead in household paint and dust is a serious health hazard, as low-level lead exposure can result in a number of adverse health effects, especially in children. Onsite and real-time detection and quantification of lead in paint/dust are very important to homeowners and certified lead-based paint removal professionals. Toward this end, both field-portable equipment (such as X-ray fluorescenc ...

SLUDGE WASTE CONTAINING CR(VI) FROM CHROMIUM PLATING OPERATIONS IS CLASSIFIED AS HAZARDOUS AND ITS DISPOSAL IS A MAJOR CONCERN. IT CAN BE RECOVERED FOR FUTURE METAL USE IN REMELTING OPERATIONS, CAN BE STORED, OR CAN BE DISPOSED AFTER MODIFICATION TO A LEGALLY ACCEPTABLE FORM. IN PHASE I, THE CONVERSION OF SLUDGE WASTE FROM CHROMIUM PLATING OPERATIONS INTO FERROCHROMIUM ALLOYS IS PROPOSED. BY MEANS ...

Strategic defense missions place a premium on the performance capabilities of onboard propulsion systems. An innovative technique for producing very high impulse at excellent thrust-to-weight ratios is known as laser-powered heat-exchanger propulsion. A remotely stationed high power laser is used to heat a propellent gas within a rocket engine, and the heated gas is exhausted to generate thrust at ...

The primary objective of CU Aerospace's Phase I work will be to investigate innovative iodine injection concepts for the chemical oxygen-iodine laser (COIL) that improve mixing at higher total pressures. The designs will be made to significantly improve the pressure recovery of COIL systems while retaining efficiency. The results of the Phase I research will lay the foundation for developing a h ...

Phase I will characterize the performance improvement of an electronic camera fitted with a Transparent Spatial Filter. Such a filter, by band-limiting an input image to match the sampling characteristics of the camera, will remove the output errors associated with undersampling. The resultant higher fidelity image will therefore yield higher performance in subsequent image processing application ...

On-site and real-time detection and quantification of lead in the paint/dust is very important to homeowners and certified lead-based paint removal professionals. Toward this end, both field-portable equipment (such as x-ray fluorescence ...

Many advanced HgCdTe (MCT) infrared detector structures are grown by the molecular beam epitaxy (MBE) technique, which is especially sensitive to small imperfections, impurities, precipitates, and polishing damage on the substrate surface. In order to achieve very high crystalline quality MCT structures, the substrate surface must be of superior quality (MBE-quality). EPIR demonstrated the ability ...

The MDA's request to detect, track and discriminate long range targets requires infrared focal plane arrays (IRFPAs) that have higher sensitivities, longer cutoff wavelengths (>14 µm), larger formats (> 256 x 256), and higher operating temperatures than the current infrared technology. PbSnTe is an ideal material for the MDA's requirements. Its carrier mobilities and quantum efficiencies are comp ...
