Today's Web portals for science only provide sparse coverage of the communities they seek to serve, typically less than 5%, because comprehensive coverage is too hard to do. This project will develop a suite if tools (which we call the X-Portal technology, where X is the community to be served), to make comprehensive coverage workable. A number of clustering methods will be collected, tested and l ...

Luna has developed new class of acceptor materials based on exclusive Trimetasphere carbon nanomaterial (TMS) technology. Trimetasphere carbon nanomaterials, have a trimetallic nitride cluster enclosed within a C80 fullerene (see Figure 1). The metals captured within the cage can be changed allowing TMS-based acceptors to be tuned to more favorably align the molecular orbitals between acceptor and ...

The need for high stability measurement of temperature and material degradation exists for monitoring in-core reactor use in planned Gen-IV reactor designs, especially the next generation nuclear plants (NGNP) such as the VHTR (very high temperature reactor) and PBMR (Pebble Bed Modular Reactor) designs. These reactors are planned to operate at temperatures above 1200

The structural degradation of fusion reactor components within high temperature magnetically confined plasma environments is a well-known problem. The high heat flux associated with the plasma, in addition to sputtering and thermal cycling, leads to detrimental erosion and cracking of the plasma facing components (PFCs) which tile the reactor walls. At present, no evaluation method exists that wi ...

Currently, power consumption and usage in high performance computing (HPC) systems is not well understood, nor is it optimized for system efficiency. Without a comprehensive understanding of the way in which system energy is being utilized along with a global view of the system conditions, HPC centers cannot function at their peak performance level, reducing productivity and increasing overhead c ...

Nuclear energy is widely held as being the only viable source of abundant, CO2 emissions-free electrical energy meeting projected needs in the near term. The primary challenges associated with emerging Very High Temperature Reactors (VHTR) stem from their extremely high operating temperatures, especially during accident conditions. This environment has necessitated new material systems to be devel ...

Concern over CO2 emissions and global greenhouse effects has prompted new uses for reclaimed CO2 effluent from coal fired power plants. Similarly, volatile organic solvent emissions have prompted an initiative to identify cleaner solvents for high performance polymer processing, particularly when such processing requires large volumes of environmentally unfriendly, toxic organic solvents. Furthe ...

This DOE SBIR/STTR program will result in the commercialization of a low-cost anostructured composite thermoelectric device. Such devices represent the next generation solution for an increasingly strained energy market by converting existing waste heat into electrical power. More waste heat is generated by the combination of industry and automobiles than the total contribution of all renewable en ...

Geothermal energy technologies have the potential to provide a significant source of clean electrical energy for U.S. citizens yet face considerable technical and economic challenges to market acceptance and integration. Of particular interest, enhanced geothermal systems (EGS) have the potential to significantly increase the quantity of extractable geothermal energy from previously unusable hot ...
