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 ...

70814 Measurements of atmospheric concentrations of CO2 and CO from aircraft and remote sites play a central role in strategies for quantifying the sources and sinks of carbon and for controlling global warming from greenhouse gas emissions. A highly sensitive, automated, and robust sensor for CO2 and CO is needed for this purpose. This project will develop an instrument to measure CO2 ...

"The terahertz (THz) wave region is an underutilized electromagnetic spectrum in which generation is difficult. The existing THz sources are generated either by large and expensive free electron laser or by pulsed optical radiations. There is an increasedneed for continuous THz wave source of high temporal and spatial coherence. The practical use of THz spectrum requires new laser technology th ...

"ZnO is an excellent candidate for the growing field of nanophotonics due to its index of refraction, availability of native substrates, and the possibility of light emission. These properties make ZnO an ideal candidate on this growing field. Phase Iwork will concentrate in designing and characterizing waveguides, which will be the interconnects of future ZnO based devices built homoepitaxiall ...

"Cermet, in collaboration with researchers at Georgia Institute of Technology, propose to implement a lattice matched AlInN using existing substrate technology. The implementation of a lattice matched substrate promises to produce near dislocation freeAlInN heterojunction for the first time while the use of an existing substrate technology dramatically lowers development cost and reduces the devel ...

"Emitech, Inc. proposes an innovative approach aimed at the development of carbon nanotube (CNT)-based thin film actuators/sensors possessing gravimetric work density up to 24000 J/kg per cycle, operating at frequencies up to 1 MHz, and at temperatures upto 700 C. This new concept is based on the quantum chemical effect of nanotube dimension change under charge doping/injection.The ability to move ...

"A drastic reduction in structural weight is an indispensable prerequisite to realize future Theater High Altitude Area Defense (THAAD) systems. Boost Defense segments of the program such as the Airborne Laser (ABL) and Space-Based Laser (SBL) require thestorage and transport of large amounts of cryogens. All elements contributing to the cryogenic system mass must be as light as possible. Advanc ...

"The program will demonstrate the scientific, technical and commercial merit of our innovative infrared window material and cost-effective production process. The materials will have IR transmission characteristics close to that of current monolithicsapphire and ALON window materials. Additionally, our self-reinforced single crystal oxide material will provide a substantial improvement in therma ...

"The continued proliferation of imaging infrared (IR) missile systems has created the need for fully representative IR scene generators. In order to test these imaging IR systems correctly, a very large dynamic range is required of the scene generator. Thiscan not easily be produced by the standard approach of an array of suspended resistor heater elements. IR optical modulators based on thermal s ...

"Diamond represents a multimillion market due to its unique combination of superior thermal, electronic, optical, dielectric, chemical, and mechanical properties. However its applications are far from fully developed. One of the hurdles is the lack of asuitable technique to make high quality diamond with low cost comparable to that of other materials in various application areas. MicroCoating Tech ...
