Redox flow batteries are a promising technology for electrical energy storage for renewable energy sources; however traditional redox flow batteries are limited in their use due to non-uniform pressure drops and mass transfer limitations, as well as high manufacturing costs related to the felt material costs for the electrode and component alignment challenges during manufacturing.General Statemen ...

The US Department of Energy has a stated goal to increase the energy efficiency of turbines, and one well recognized method of achieving this is through the use of ceramic thermal barrier coatings (TBCs). However, state of the art zirconia-based TBCs have a temperature limit of about 1200oC, and new TBC materials that can operate at elevated temperatures of 1300oC and above are needed to continue ...

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, ...

Due to huge levels of computing parallelism and higher performance per watt, comuting accelerators are crucial for increasing HPC efficiency. This is economically significant for small and medium size manufacturing companies (SMMs) and essential for transition to Exascale computing. However, due to high procurement costs, in-house maintenance of an accelerated HPC cluster is prohibitive for many ...

Development of a solid with high conductivity of Mg2+ cations will allow application of that substance as membrane in magnesium-air batteries. These batteries will be much cheaper, safer, and at the same time store much more energy than lead-, lithium- or sodium batteries with the same weight. Such batteries would be ideal for electric vehicles and for the off-peak storage of renewable elect ...

Solar water heaters are a well-established renewable energy technology that has been widely adopted outside of the United States. Here we propose to significantly improve the evacuated solar tube collectors (ETC) by utilizing the dry-drawable carbon nanotube (CNT) sheets for solar energy absorption and CNT multifunctional nanocomposites with functional layers of heat accumulators and heat transpo ...

The ultimate goal of the project is to demonstrate that the rotating liner engine (RLE) can increase fuel efficiency in heavy duty vehicles by about 3.5-4% at full load, about 25% at idle, and about 10% for an average duty cycle, can reduce CO2, NOx and PM and reduce engine wear. Design already completed. The face seal is the only technical challenge of the concept, and the main design features pe ...
