One effective way to lower the weight, thus decreasing the carbon fiber usage and lowering the cost, of a CFRP tank is to improve the mechanical properties of the CFRP composite resin matrix using nano-reinforcement. Using the resin matrix itself as a source of composite strength, along with the carbon fiber reinforcement, results in a tank that requires less carbon fiber material. This solution d ...

III-V semiconductors based solar cells display the highest sunlight conversion efficiency. Nevertheless, the material cost of current III-Vs and their fabrication process is very high which impedes their use for flat panel, large market applications. This project aims to explore, evaluate and implement defect tolerant high efficiency tandem solar cells based on more earth abundant III-V materials ...

Increased use of hydrogen as a fuel can provide benefits to our nations energy security, the environment and economic growth. Toward hydrogen economy, an innovation in hydrogen separation technology is needed in the production of hydrogen. Current separation technologies for industrial hydrogen production mainly include pressure swing adsorption process and the cryogenic separation process, which ...

SelfPowered wireless sensors are needed on hightemperature rotating turbine engine components for real time sensing of component health. Conventional temperature, pressure and strain sensors use wired connections and slip rings which are not desired. Conventional wireless technology uses transmitters containing active semiconductors which degrade upon high temperature exposure. Although numerous w ...

Measurement of the longitudinal charge distribution of short electron bunches moving with relativistic velocities is among the major challenges in the domain of accelerator diagnostics. The strict control of the longitudinal distribution is critical for the operation of X-ray Free Electron Lasers (FELs) and Energy Recovery Linacs (ERLs). Several techniques are presently employed; however, none of ...

Redox flow batteries (RFBs) have the potential for economical storage of electrical energy than other battery chemistries. They use high-cost ion exchange membranes as separators between anolyte and catholyte, which prevent broad market penetration. Proton exchange membranes (e.g., Nafion) are poorly selective, allowing undesired cross-diffusion of active species in solution electrolytes across t ...

The aim of this proposal is to facilitate the access that non-researchers have to data generated from high-resolution, long-term, climate change projections performed as part of the U.S. Global Change Research Program. Effective analysis in climate science depends on having the appropriate cyber infrastructure to enable people to discover, access, manipulate, and visualize the large and complex da ...

Researchers at SLAC ACD have developed a new generation of high-order finite element procedures for electromagnetic analysis that cans effectively simulation new accelerator designs. These same analysis procedures are well suited for electromagnetic applications ranging from threat detection, to antenna design, to wireless device design, to the treatment of cancer. Cost effective massively paralle ...

Current nuclear material measurement techniques are limited in the ability to assess the ratio of actinides such as curium (Cm) and plutonium (Pu) present in the sample from the beginning to the end of processing. As a result, it is difficult to discern whether nuclear material is safeguarded correctly, i.e. is it being diverted? The opportunity addressed is a substantial improvement in measuremen ...

Separations chemistry is an important tool that is employed for a wide variety of applications associated with DOE missions. The ligand 4-chloro-2-[(6-chloro-7-methyl-2H-1,3-benzoxazin-3(4H)-yl)methyl]-5-methylphenol is currently employed as an additive to solvent extraction methods, which are neither rapid nor environmentally sound due to large quantities of toxic waste generated. The development ...
