Asymmetric ultracapacitors achieve greater energy density versus today

The cost of dewatering particles is inversely proportional to particle size. Costs dramatically increase as particle size approaches 10

Coal is an abundant source of energy in the USA, but is not currently utilized effectively. Recently, the DOE has begun a carbon sequestration program is to develop advanced CO2 capture and compression technology for existing coal-fired plants with increased efficiency with no more than a 35% increase in the cost of electricity. This will require new approaches and technologies to be successful. N ...

Solid state lighting is being promoted as the ultimate lamps of future. Though the internal quantum efficiency of OLED devices is almost 100%, external efficiency is a mere 36% mainly because of poor light out-coupling (~40%) from the device. Improvement in light out-coupling to >70% and further reducing the manufacturing cost will rapidly accelerate the commercialization of the OLED technology. T ...

The fabrication of high-quality ultra thin (~20 micron) diamond crystals targets for 9 GeV highly polarized photon beams is an outstanding challenge. Current state of the art polishing/thinning techniques are not successful in thinning single crystal diamond to such dimension because of its extreme hardness and chemical inertness. These techniques create significant stresses surface and sub-surfac ...

Critical to determining the success of an EGS well is the measurement of the flow distribution along the open-hole length of that well. Knowledge of not only the depth but the spacing of intersected fractures is required in order to determine the sweep efficiency of fluids flowing through the reservoir. Currently, the only device available for measuring fluid flow within a geothermal wellbore is t ...

While there is no lack of performance counter tools for coarse-grained measurement of cache activity, there is a critical lack of tools for relating data layout to cache behavior to application performance. Generally, any nontrivial optimizations are either not done at all, or are done by hand requiring significant time and expertise. To the best of our knowledge no tool available to users measure ...

Selection of the Plasma-Facing Component (PFC) material composition is a primary consideration in future fusion reactor design. The PFC materials must not only withstand the harsh operating conditions of the reactor, but the amount of tritium uptake experienced by the PFC during operation is a significant factor. Proper operation, safety and environmental impact mandate that t ...

A significant portion of the waste heat from engine exhaust can be recovered using thermoelectric generators to achieve up to 10% gain in automotive mileage. There have been several efforts underway on this front but most have focused on demonstrating thermoelectric generators using bulk materials that consume significant amount of raw materials and are prone to failures due to thermal expansion, ...

Successful adoption of open frameworks such as perfSONAR in Science DMZs within DOE labs, universities, and small-businesses, and the emerging trends of software-defined cloud platforms that inherently require multi-domain performance transparency are major drivers for a new market. However, perfSONAR framework and other proprietary solutions developed by industry cannot be effectively integrated ...
