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 ...

Solid State Drives (SSDs) are emerging as attractive alternatives to traditional HDDs due to there reduced power consumption and potential for increased performance. SSDs have the potential to improve the performance of both Checkpoint Restart (CPR) and the Metadata Server (MDS) for high performance File Systems, e.g., Lustre. However, the write performance of SSDs is relatively poor (compared to ...

Energy consumption is quickly becoming one of the primary bottlenecks of compute clusters and supercomputers. The DOE is a primary developer and consumer of these power hungry supercomputers, however smaller cluster machines are also widely used through other government agencies and industries. Yet, there are few power profiling tools that allow application developers transparent insight into the ...

Currently the commercially available technologies for H2 separation such as pressure swing adsorption and cryogenic distillation are very energy intensive. Membrane technologies can be very energy efficient; but for high selective membranes low flux and high cost are the major challenges that frustrate commercialization. Recently, cermet has shown promise because of less precious metal usage and m ...

Higher operating temperature for the gas turbine engine is needed for enhanced efficiency, lower emission and increased performance goal. The current state-of-the-art thermal barrier coatings (TBCs) are not adequate to provide the needed protection for the metallic components of the turbine engine operating at higher TBC surface temperature (>1300

Hydrogen produced today from coal, natural gas, or biomass must be separated and purified outside the reactors using pressure swing absorption (PSA), a process that requires significant additional space and energy. Placing hydrogen-permeable membranes inside the reactors themselves would allow hydrogen to diffuse out, thereby reducing the cost of hydrogen production. In this Phase I effort, Mainst ...
