Advanced new and upgraded synchrotron X-ray beamlines and sources are being constructed worldwide, and these facilities require fast new X-ray detectors to complement them and foster new scientific applications. In particular, new detector capabilities are desirable in the time domain, for the study of fast material and molecular kinetics, in the intensity domain for keeping up with brighter X-ray ...

Redox sensitive heavy metals - chromium, iron, manganese, and copper have attracted a great deal of attention around the world for their impact on human health and environment. It is beneficial to study the temporal dynamics of metal ion concentrations and coupled biogeochemical reactions. Traditional systems are expensive to use with costly and bulky instruments, and are not suitable for field mo ...

High Performance Computing technology has advanced significantly. Advanced parallel computers are being built, with DOE leadership. Yet, the American engineering/manufacturing industry has not leveraged parallel computing at a significant level, partly because of the challenging nature of modern simulation software. US competitiveness in manufacturing may suffer due to its ineffective utilization ...

One of the overarching goals of the Department of Energy’s Biological and Environmental Research (DOE- BER) program is the quantification of biogeochemical processes in complex subsurface environments at the Hanford Reach of the Columbia River in Washington and East River flood plain in Colorado. The models informed by this data are useful for predicting both short- and long-term changes to econ ...

Environmental sensor networks capable of taking data quickly enough to capture minute-scale fluctuations and durable enough to capture these data for entire seasons provide essential information for studying the seasonal and annual effects of environmental activity across complete ecosystems. The models informed by this data are useful for predicting both short- and long-term changes to economical ...

The Department of Energy’s Office of Nuclear Physics Isotope Development and Production for Research and Applications Program has identified a need for materials that will survive high radiation environments to support next generation rare isotope beam facilities. Specifically, long-lifetime, rotary vacuum and water seals are needed to survive 0.5 – 15 MGy/month. Current gaskets and seals do n ...

Reducing the size, weight, and increasing the efficiency of automotive traction power inverters requires the development of novel high-voltage, high current silicon carbide high-speed transistors and rectifiers, since the existing silicon technology is severely limited in terms of operating temperature, frequency and energy efficiency. However, the non-optimized device and manufacturing technology ...

Continued use of nuclear power is critical to meeting carbon emission goals and ensuring national security. Nuclear power production will rely on both current generation (LWR and PWR) as well as next generation designs including very-high-temperature, molten-salt, supercritical- water-cooled, gas-cooled, sodium-cooled, and/or lead-cooled reactors. The development and deployment of these high tempe ...

Significant amounts of time and resources are spent generating and maintaining meshes for modeling and simulation by engineers and scientists in industry, government, and academia. Beyond mesh generation, one major problem complex multiphysics software, such as those used in nuclear energy software, currently faces is the complex transfer of quantities between meshes during high-performance simula ...

The size of the latest generation of wind turbines is outstripping the capabilities of the materials and techniques used to manufacture them. As wind turbines are made larger to improve efficiency, composites with improved mechanical properties and long term performance are required to avoid premature field failures. Further as wind turbines are produced in ever greater numbers, faster manufacturi ...
