Solid state lighting is being promoted as the ultimate lamps of future. Though the internal quantum efficiency of OLED devices is almost 100%, external efficiency is a mere 36% mainly because of poor light out-coupling (~40%) from the device. Improvement in light out-coupling to >70% and further reducing the manufacturing cost will rapidly accelerate the commercialization of the OLED technology. T ...

The fabrication of high-quality ultra thin (~20 micron) diamond crystals targets for 9 GeV highly polarized photon beams is an outstanding challenge. Current state of the art polishing/thinning techniques are not successful in thinning single crystal diamond to such dimension because of its extreme hardness and chemical inertness. These techniques create significant stresses surface and sub-surfac ...

Providing a reliable, clean and economical energy source is a priority of the US government. The challenge is to use coal, a secured and economical energy source, to produce clean hydrogen fuel to support domestic and global green economy with near-zero emission. Conventional separation technology and even developmental technology do not satisfy all of the requirements for hydrogen production from ...

Conversion of sunlight to chemical fuels by artificial photosynthesis has been a long-sought goal. The major goal of the proposed effort is to develop a novel fuel-generating (e.g., hydrogen) photolytic device, which consists of a semiconductor nanowire decorated with metal nanoparticles. The project targets a low-cost technology by fabricating and utilizing the nanowire-nanoparticle conjugate de ...

We propose to develop a commercial weakly ionized plasma modeling capability based off of Tech-X’s high energy density plasma fluid code TxFluids. The new additions will be able to be used to model hypersonic vehicle physics including shock waves, plasma chemistry and innovative techniques for blackout mitigation and hypersonic vehicle control through the application of electric and/or magnetic ...

A computational and experimental research program is proposed to develop and validate a high-fidelity 3D non-equilibrium magnetohydrodynamic (MHD) plasma compressible flow code for advanced aerospace applications. The code will incorporate a physics-based kinetic model of air plasma with non-equilibrium conductivity sustained by an externally applied electric field. The model will include electron ...

We propose to design, analyze, implement, and evaluate a system that enables user-verifiable execution of code on untrusted computer systems in the presence of malware. Our system is based on a secure hypervisor that provides and enforces strong security

Aluminum as a structural material for naval applications has a number of advantages over steel, owing mainly to significant weight reductions which translate to higher speed and range attainable by aluminum vessels. A comprehensive study of research needs for aluminum structures conducted under the ONR program identified the key research areas, which included material behavior and fracture evaluat ...

Conventional photovoltaic technologies have been able to achieve limited market penetration due to high first costs and reductions in efficiency caused by the high operating temperatures at which the panels are typically employed. Traditional solar panels are also configured as mounted equipment, separate from the building envelop elements. The use of unaugmented PV power generating technology l ...

Highly scalable parallel random number generators (RNGs) will be developed, evaluated and implemented for use in high performance computing on thousands of multi-core processors and general purpose graphics processing units. The main contributions are: (a) design and implementation of new parallel test methods that capture the inter-stream correlations exhibited in practice and complement the curr ...
