Performing accurate simulations of large- and multi-scale electromagnetics problems has far-reaching implications The same physics governs applications as diverse as rare earth content reduction in DC motor design; wireless propagation in dense urban environments and novel antenna design, both key issues in the pending 5G communications boom; electromagnetic sounding for subsurface exo-terrestrial ...

The combination of X-ray absorption spectroscopy (XAS) with x-ray emission spectroscopy (XES) provides unique diagnostic analysis of both the structure and chemical composition of complex heterogeneous materials. The penetration of X-rays make this method ideal for studying and optimizing material properties under realistic, real time reaction conditions with simultaneous analysis of reaction pr ...

Commercial-scale geothermal reservoirs are thousands of feet below the Earth’s surface, so scientists rely on indirect measurements to reconstruct 3D subsurface reservoir maps from seismic vibrations, electromagnetic waves, or gravity measurements. Geothermal operators typically use electromagnetic or gravity surveys, but seismic surveys are preferable because they enable higher-resolution 3D su ...

A number of unique non-destructive testing techniques and fundamental research studies are enabled by the modern bright pulsed neutron sources. In addition to all the methods previously developed at continuous neutron sources the pulsed structure of neutron beam enables a number of novel methods with the measurement of neutron energy through the time of flight technique. Despite the fact ...

Wind power plays an increasingly important role in satisfying the power needs of the United States With increased market penetration, failures from unanticipated unsteady loads, installation related reductions in power generation and significant maintenance costs have underscored the need to predict the unsteady fluid structure interactions related to turbine layout and off-design wind conditions ...

Wind power has an important role in satisfying the power needs of the United States. Since wind power is a clean renewable source of energy, it also serves an important role in reducing dependence on fossil fuels, in particular foreign oil supplies, as well as reducing greenhouse gas and carbon emissions. Unfortunately, significant maintenance costs, recently highlighted by a series of blade failu ...

The development of radiation detection materials would benefit with greater access to computational models that relate physical traits seen in manufacture with complex energy transitions occurring in the material that control operating performance. However, the HPC requirements behind these models remain beyond the reach of most businesses involved in this small yet vital field impacting National ...

Intense short pulse lasers are playing increasingly important role in high-energy physics research. Laser based electron accelerators are innovative tools to obtain GeV to TeV electron energies for high-energy particle physics experiments. The development of such lasers puts stringent challenges on the very limits of the laser materials themselves. The goal of this project is to develop Ho:sesquio ...

Ceramic matrix SiC-SiC composites are currently the leading candidate for Generation IV nuclear reactor fuel cladding and other structural components, due to their excellent thermal and chemical stability under extreme conditions. However, robustly joining SiC structures when exposed to such harsh operating conditions still presents a major roadblock. A novel bonding joint compound leveraging grap ...

The Exascale Computing Project is tasked to develop the next generation of high performance computing systems capable of computing at 50 to 100 times faster than current HPC systems. Computing at this extreme-scale will significantly enhance the value of materials modeling and simulation to basic materials research and engineering In particular, computing at the extreme scale will enable a higher ...
