With the 4 billion tons of uranium estimated to be dissolved in the earth & apos;s oceans, an essentially unlimited resource is available to those with easy and affordable access. With decades of research towards the extraction of uranium from seawater, focus has been directed towards the selectivity of the adsorbent material, the cost of the material, and the ability of the adsorbent to be recycl ...

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 ...

Computer simulations of multi-phase flows are important for many applications. In the proposed work, we plan to advance Eulerian-Lagrangian methods by using Adaptive Mesh Refinement for multi-scale resolutions, and CPU-GPU parallelization to drastically reduce computing time. Eulerian-Lagrangian methods treat the gas/liquid phase as a continuum (Eulerian) fluid, and solid particulates as discrete ...

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 ...

The TAU Performance System is a powerful and highly versatile profiling and tracing tool ecosystem for performance analysis of parallel programs. Developed over the last 15 years, TAU has evolved with each new generation of HPC systems and scales efficiently to hundreds of thousands of cores on the largest computers in the world. TAUs organic growth has resulted in a loosely coupled potpourri of ...

Tungsten and its alloys are candidates for plasma facing component heat sinks and armor due to their low sputtering rate, high melting point, high thermal conductivity, high strength at elevated temperatures and low tritium inventory. However during service, the plasma facing components will be exposed to a high flux of 14MeV neutrons from the plasma and low energy neutrons from the blanket, whic ...
