70042 The quantification of sources and sinks of atmospheric carbon dioxide would be greatly facilitated by the development of a new detector for this important greenhouse gas. In particular a lightweight CO2 sonde, similar to the widely used ozonesonde, could be used to estimate landscape-scale fluxes of CO2 characteristic of ¿ 100 km2 from vertical profiles through the convective bound ...

65657 Coal-fired power plants represent the single largest source of mercury emissions to the atmosphere, and the EPA has announced its intent to regulate the emission of mercury from these plants in 2007. Estimates by EPA and others predict that the annual cost of controlling 90% of current mercury emissions will be $2-5 billion. This estimate is based on the injection of activated carbon, ...

70474 Phytoextraction is frequently the most cost-effective method available for removing toxic metal and radionuclide contamination from the soils, sediments, and groundwater at many DOE facilities. In order to ensure that the site remediation proceeds as quickly and at the lowest cost possible, it is necessary to confirm that the plants are healthy, actively growing, and taking up the con ...

"A suite of modular, rugged, easily deployable, field maintainable sensor pods capable of acquiring weather, chemical warfare agent, pollution, geographic and seismic data that can be tailored for multiple missions would provide essential battlefieldintelligence. These sensor pods would auto-network together to relay spatially and temporally stamped data back to a central hub with little user set ...

"Chemical warfare agents (CWAs) offer a particularly insidious threat to both military and civilian populations. The U.S. DOD uses a series of tools at the troop level including individual detection, point detection, and standoff detection to warn of CWAattack. These technologies are prone to various problems, including scuffs, lack of selectivity, and lack of sensitivity to gas-phase CWAs. Of p ...

70367 Coal gasifiers have the potential to provide electric power more efficiently, and with less pollution, than conventional coal-combustion power plants. However, gasifier processes emit mercury, a toxic metal regulated by the EPA, and current technologies to remove mercury from coal-combustion gases are ineffective in gasifiers. This project will develop and demonstrate a technology for re ...

"MEMS (micro electro-mechanical systems) market was supposed to make the breakthrough in miniaturization. In practice, they are limited in power and so are reduced to very simple optical uses. With this engine, a new world of applications will be availablein the defense, space, communication and medical industries.We propose an engine 1,000X faster; smaller; and more powerful than electrically pow ...

"The SBIR Phase I work uncovered that the most expensive and challenging aspects of multi-satellite projects are the ability to build and test the satellites in a simulated environment that provides a high fidelity validation in a distributedtest-like-you-fly environment at a reasonable cost. Expanding on three of the four elements investigated during Phase I, ASI will construct components that c ...

"The acoustic signature generated by test articles in high speed wind tunnel tests is difficult to measure due to the high level of background noise created by the wind tunnel flow. A unique research program using microphone arrays is proposed to addressthis issue. The program combines experimental tests and analytical algorithm development to devise a system able to reject the undesirable wind tu ...
