The proposing company's reformable, reusable tooling can substantially reduce the time, cost and effort associated with conventional or alternative tooling while providing the flexibility for prototyping iterations, short-run or low rate manufacture through lengthy product cycles. This Phase II project addresses the use of reformable tooling materials and tooling systems for the production of prot ...

75867 Mercury (Hg) emissions are an important environmental problem because Hg is a volatile heavy metal that is toxic and bioaccumulates to a high degree in animals and humans. The major sources of Hg emissions include fossil fuel combustion, waste incineration, and chloralkali production. With the increased development of coal gasification technologies, the monitoring of Hg in gasifier synthe ...

76214-Next generation experiments in High Energy Physics require the use of thinned detectors with high density interconnects; however, present manufacturing techniques for wafer thinning produce very low yields. Standard processing techniques have proven to be unacceptable for the production of high pixel count detector assemblies. Therefore, this project will develop technology for plasma-etch ...

75630-The most efficient solid-state white lights developed so far typically use a bright blue light emitting diode. The diode is used not only as a blue source, but also for the simultaneous optical excitement of an inorganic downconverter, which converts a fraction of the blue light to yellow. When the yellow light is mixed with the remaining blue, it is perceived by the human eye as white. H ...

75487-Restricted natural gas supplies, reduced peak electrical capacity, and steadily increasing demand for domestic water heating are placing a strain on limited conventional energy resources. Water heating is one of the most practical uses of solar energy; efficiencies for solar water heaters often exceed 75% compared to 15% for typical photovoltaic systems. However, despite rising conventiona ...

Teh objective of the proposed work is to develop a process for the fabrication large-area aluminum nitride (AlN) wafers of up to 2" in diameter for III-nitride substrate applications. The growth process is based on a sublimation technique that utilizes adequately prepared SiC wafers as large-area seeds. A multi-step process developed in Phase I will be upscaled to larger area deposition, and will ...

The goal of this collaborative effort between InsituTec Inc. (NC), TRS Technologies Inc. (Pa) and Center for Precision Metrology at University of North Carolina at Charlotte, NC is to demonstrate the closed loop control of a high-speed, long-range rotational stage. This proposal addresses design, manufacture and testing of a high-bandwidth steering-mirror employing a monolithic mirror-flexure stru ...

Kyma Technologies, Inc. will demonstrate high-performance gallium nitride (GaN) microelectronic devices for X-band radar applications using single crystal semi-insulating GaN substrates. FETs for power amplifiers will benefit from lower defects resulting from growth on a native GaN substrate. The thermal conductivity of the GaN substrates will be characterized and device structures will be modeled ...

Gallium nitride substrates are now being produced by several manufacturers, however significant market penetration is being limited by high prices and low quantities. This Phase II program is aimed at addressing both of these issues by developing a growth process for the production of 1cm thick boules at a growth rate of 1mm per hour. The Phase I program met and exceeded the goals of demonstrati ...
