Metal-Organic Chemical Vapor Deposition (MOCVD) epitaxial processes are used to deposit the GaN, InGaN, AlGaN and other wide band-gap semiconductor thin films making up the buffer, quantum well, and cap layers of the next generation high- brightness LEDs (HB-LEDs) for Solid State Lighting (SSL). Non-uniformity of the central wavelength over the wafers, batch-to-bat ...

LightSpin Technologies, Inc. proposes to develop radiation-hard GaInP Photomultiplier Chips. GaInP is extraordinarily radiation hard, capable of withstanding at least 100,000-fold higher radiation flux than silicon. LightSpins GaInP Photomultiplier Chip technology enables the production of GaInP photon detectors with high gain, low noise, fast rise/fall times, and wide dynamic range across photo ...

Better fuel economy and stringent environmental requirements continue to drive the search for engine oil lubricants with better performance and less pollution concerns. Inorganic additives have demonstrated good friction reduction results and eliminated the hazardous components from traditional organic friction modifiers. However, their dispersibility in lubricant formulations has been non-satisfa ...

Thermochemical processes are noted for their inherent difficulty in producing clean gas/vapor streams for fuel or chemical production, especially where catalytic upgrading of the gas stream is desired. The gas cleanup system can also account for a substantial portion of the overall capital cost. The carryover of char for example not only produces undesirable particulate contaminants, but also has ...

Many parallel performance, profiling, and debugging tools require a graphical way of displaying the very large datasets typically gathered from high performance computing (HPC) applications. Most tool projects create their graphical user interfaces (GUI) from scratch, many times spending project resources on simply redeveloping commonly used infrastructure. We propose to create a multi-platform GU ...

There is a current need for technology that can convert waste heat to electric power in an effort to achieve significant improvements in fuel efficiency and lessen our dependence on environmentally hazardous, foreign produced fuels. Thermoelectric Power Generation (TEPG) is the most efficient and commercially deployable technology for this need. However, commercial integration of TEPG with automo ...

The U.S. DOE Office of Environmental Management (EM) was created in 1989 to manage the cleanup of large areas of environmentally contaminated sites. Since the closure of many of these sites, U.S. taxpayers have spent about $220 billion at 74 cleanup sites. However, these sites were the smallest and most manageable sites to clean. There are still over 40 sites that are deemed as eno ...

The carbon dioxide produced from coal-fired power plants can be captured and used to grow algae. The algae convert CO2 into natural oils that are suitable for conversion into biodiesel. However, harvesting the algae and extracting the oil are currently difficult and expensive operations. Cheaper, more-energy-efficient processes are required before mass production of algae can be used to produce ...

Structural health monitoring is vitally important to prevent the catastrophic failure of critical components in advanced power plants, to optimize inspection and maintenance schedules, and to avoid unplanned outages. Acoustic Emission (AE) techniques have proven to be an effective non-destructive evaluation (NDE) method capable of continuously monitoring micro-structural changes that result from ...

As numerous documents and data sets accumulate in the science and technology area, the analysis of this information for the purpose of facilitating federated research becomes a challenging task. This project will develop efficient and scalable data mining solutions to conduct data integration, anomaly detection, and correlation. The key innovation of the proposed tool, the DSTMiner (Distributed ...
