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 ...

70576 The Nb3Sn superconductor is an enabling technology that will determine the future of high-energy hadron colliders for high energy physics research. Unfortunately, the cost of the Nb3Sn superconductor is ten times that of other superconductors. The high cost comes not from materials, but from the necessity to fabricate the multi-filament wire in small batches. Batch size is limited by ...

65438 Large particles must be efficiently removed from powders used to fabricate superconducting wire. The presence of even a trace amount of large particles can ruin the superconducting properties of a large batch of wire, and limit the performance of all wire made with the powder-in-tube process. This project will apply an aerosol sorting technology to remove this limitation to supercon ...

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 ...

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 ...

70585 There is a need for the conditioning and monochromatizing of neutrons for medical, industrial and scientific purposes. Currently, the most favored techniques for monochromatizing neutron beams are mechanical, reflection, and diffraction methods. However, these methods have only limited efficiency and great cost. This project will design and fabricate a neutron monochromator that will ...

70307 Many DOE sites have the need to monitor radionuclide contamination in surface water, groundwater, soils, and the vadose zone. In many cases, a real-time and/or remote monitoring capability is desired. Existing site characterization procedures typically involve the collection and shipment of samples to an off-site laboratory, which leads to costly delays in site remediation as ...
