Various oily wastes are generated when performing vehicle maintenance operations, including used oil drained from the engine, the oil filter, and even oil absorbent used to clean up oil that has spilled on the floor. At one time these wastes were placed in landfills. Concerns with oil from these wastes migrating into surface and groundwater has prompted a number of state and federal ...

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 ...

Southwest Sciences proposes the development of an optical, near-ultraviolet chlorine dioxide (ClO2) sensor having a measurement range of about 0.01 to 2000 ppm with a response time of less than 10 seconds. The sensor will be compact—about the size of a 1-quart milk carton including electronic and optics, operate at low power, and be outfitted with a wireless communications interface to permit re ...

Using the unique spectral characteristics of its proprietary fractal-microcavity composite, LaSys, Inc., will perform the proof-of-concept research required to develop an ultra-sensitive optical detector of low concentration of arsenic in water based on the Raman effect. The Phase I technical objectives are designed to demonstrate that fractal microcavity composite-surface-enhanced ...

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 ...

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 ...

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 ...
