The proposed project is to demonstrate a novel technique for producing GaN single-crystal boules that yield GaN wafers and substrates suitable for fabrication of GaN high-power devices. The two key attributes of the proposed novel GaN growth technique (a bulk crystal growth technique) are: a high growth rate and an ability to achieve a superior crystal quality. The novel GaN crystal growth techn ...

In the proposed effort, we will leverage this extensive experience and capabilities to realize a frequency agile mmW radiometer that can cover the range of DC-110 GHz and can be scaled to DC-200 GHz under Phase II. Ours is a photonic system that multiplies and up-coverts a low-frequency reference signal onto an optical carrier (laser) using EO modulation, then uses the modulation sidebands to inj ...

To ensure safe and reliable power production by nuclear power plants, a wide variety of materials and components need to undergo inspections and maintenances at pre-determined intervals. Condition based maintenance is highly desirable because it can potentially avoid unnecessarily costly maintenance actions and associated error induced failures. Consequently, it can help achieve nearly all the mai ...

Dimethyl carbonate (DMC) is a high value organic chemical with many potentially important applications. DMC can be made from CO2 directly or indirectly. With the development of CO2 capture and sequestration technology, huge amounts of low cost CO2 will be available as a feed stock. The conversion of CO2 to DMC will be an attractive chemical production investment. A major problem associated the D ...

This SBIR Phase I proposal is aimed to develop advanced soft magnetic nanocomposite materials with low loss, high flux density, and capability to operate at high frequency ranges (100kHz-10MHz). With Spectrum Magnetics & apos; proprietary technique, we will develop magnetic flake materials with thickness in the nanometer scale, which effectively reduces the eddy current loss and eliminates undesir ...

Monomers and other chemical intermediates are typically obtained from non-renewable resources, specifically petroleum. Renewable resources, such as plant derived biomass, may become a significant source of these critical materials but new technology is required for their safe and efficient production. Compact Membrane Systems (CMS), in collaboration with the group of Professor Robin Rogers at th ...

Changing technologies in the high-performance computing (HPC) space lead to the creation of new tools and libraries to support each emerging paradigm. Many of these are designed only for specific configurations or for use in certain cases, which makes it difficult for a programmer to know which tool or library to use when and how to transition software built for one system to a new configuration. ...

The Advanced Scientific Computing Research (ASCR) program from the Department of Energy (DOE) has over the years sponsored the development of many important codes, such as Lattice QCD, Trilinos, PETSc, and Paraview, some of which are libraries. The use libraries in their code allows scientists to concentrate their efforts on their science rather than on the implementation of an often-implemented m ...

This SBIR project will be devoted to the development and demonstration of high-power X- band switches to operate with the two resonant delay lines of the SLED-II pulse compression system. Each switch is triggered with an intense electron beam drawn from a diamond-coated molybdenum cold cathode. Preliminary tests of prototype X-band switches using the Omega- P/NRL X-band magnicon have already sho ...

The development of an APC Nb3Sn superconductor with tin-pin artificial pinning centers by the proposed approach in the Phase I program, is anticipated to have a significant impact on cost and performance in applications for undulator magnets. The overall technical approach for the Phase I project will be to develop and demonstrate an Nb3Sn superconductor with tin-Al2O3 pins for HEP magnets. The ...
