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 ...

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 ...

The Department of Energy’s Office of Basic Energy Sciences has identified a need for new proton conducting membranes for solar fuel generator applications. Specifically, development of block copolymers with good proton conductivity at ambient temperatures and low gas diffusion and ionic transports are needed. There are currently no commercially available proton conducting membranes which possess ...

Direct fired supercritical CO2 (sCO2) cycles are gaining interest because of their potential as a zero emission power source that operates at high efficiency. The oxy-combustors in these systems operate at high supercritical pressures and current simulation tools to support design evaluation are deficient in this regime. Our proposed work here addresses this deficiency. The proposed program seeks ...

In a pandemic or exposure to weaponized Marburg virus the morbidity, mortality and social unrest that will ensue before vaccines orMilitary operating on foreign soil as well as to the population of the US Homeland. Practically all threat agents of biological origin (except forcertain non-proteinaceous toxins, typically produced by marine organisms and fungi) have their structure and vital function ...

Marburg virus (MARV) is a filamentous enveloped non-segmented negative sense RNA virus. This viruse is considered to be extremelydangerous with case fatality rates as high as 88-90%. Extensive efforts have gone towards effective vaccines for MARV prevention, however,none have been successfully established as licensed vaccines. Glycoprotein (GP) is the only surface protein of MARV. There are substa ...

In resource limited settings, rapid and accurate diagnosis of infections is critical for managing potential exposures to highly virulent pathogens,whether occurring from an act of bioterrorism or a natural event. This is especially important for hard to detect intracellular bacterial andalphavirus infections, that overlap symptomatically and often treated empirically due to a lack of reliable and ...

High performance supercritical carbon dioxide (sCO2) turbo-expanders/power turbines will provide significant increases in efficiency and compactness, while reducing greenhouse gases and water usage. However, the needed operation in a 900°C environment is a challenge for this type of turbomachinery. While magnetic bearings have many advantages over foil bearings, including no wear during startups, ...

The majority of hybrid electric vehicles and electric vehicles (HEV/EV) products use interior permanent magnet (IPM) synchronous machines for traction purpose due to the efficiency and power density consideration. IPM machines use high energy density rare earth based magnet materials such as neodymium and dysprosium. Variable flux (VF) machines using abundant and cheaper soft magnets such as AlNiC ...

The structure of the electric utility business has long been a centralized model where an electric utility is the only authority selling electricity to, and buying excess rooftop PV generation, from customers. This is changing as utilities explore new business models including Distributed System Operator (DSO) models. On the other side of the meter, with the increasing penetration of rooftop solar ...
