The JLab Electron-Ion Collider (JLEIC) is proposed to collider spin-polarized beams of electrons and ions at high energy and high luminosity- Sustaining high luminosity requires the use of bunched-beam electron cooling to control emittance growth in the circulating ion beam- The electron cooling requires that a bunched electron beam be coalesced with the ion bunches so that they travel with the sa ...

Current computational predictive tools are not benefited from state-of-the-art algorithms and hardware to simulate complex physical-chemical processes which occur in various material and energy systems- These simulation software: 1) simplify complex geometries, 2) model either physical or chemical processes, 3) are incapable of capturing physical and chemical properties which span vast length scal ...

Shale oil and natural gas, recovered mainly via hydraulic fracturing, has a significant role in meeting the U-S- energy demand in near future- Characteristics and properties of injected fluids used in hydraulic fracturing directly affect the amount of recovery- Since current injection fluid technologies result in low recovery factors, oil and gas industry is seeking new injection fluids to increas ...

Mass spectrometric measurement of elemental isotopic ratios from solids has been mostly obtained by secondary ion mass spectrometry (SIMS) which has a sensitivity for almost all elements superior to Xray fluorescence and laser desorption ICPMS- In SIMS elemental and molecular ions are liberated from the near surface of a solid by energetic micron or submicron focused ion beams and extracted with a ...

Hydrocarbons will remain an important energy source for the foreseeable future- Unconventionals are plentiful but decline quickly- Successful application of AERO Technology can recover a significant portion of this enormous resource into the world's energy marketplace- AERO technology acts via interfacial tension alteration and bio-diversion of fluids to improve oil mobility and sweep efficiency â ...

Despite its potential to lower costs and increase throughput, roll-to-roll nanomanufacturing has yet to become widely used by the private sector due to a lack of industry standardization and the dearth of available data on roll-to-roll process limits- To address this knowledge gap and increase roll-to-roll adoption, a high-performance computing simulation tool will be developed- This tool will pro ...

Polymer-electrolyte membrane (PEM) fuel-cells are one of the most promising energy conversion technologies for renewable clean energy applications- A major challenge preventing the widespread use and commercialization of PEM fuel cells is achieving high performance with low-loadings of platinum group metal (PGM) catalysts- One of the factors driving performance limitations in the cell is the mass ...

Nanotechnology has yet to live up to its promise of exploiting properties which emerge at the nanoscale because of the lack of manufacturing precision to control the nanoscale dimensions, thus denying society many energy saving materials and applications. This project targets a key component of an Atomically Precise Manufacturing system: a high-speed sub-nm-precision manufacturing platform for ato ...

One of the major maintenance headaches causing increased operational cost in the production of mature oil wells is the elimination of wax and paraffin buildup in the production tubing. The accumulation over time of paraffin compounds in "cold spots" in the tubing creates high pressures and flow constrictions that contribute to accelerated pump wear, and constrict the flow of fluids to the surface. ...

Cost-effective and power-efficient radiation tolerant semiconductors are needed in various harsh environments, such as particle detectors, communication satellites, high-altitude avionics and medical imagining equipment. These include amplifiers, voltage regulators, analog-to-digital converters (ADCs) and digital logic circuitry. However, radiation-tolerant high-speed ADCs currently cost more than ...
