Determining the environmental benefit of artificial spider silk products

Lauterbach A.Y., Scheibel T., University of Bayreuth, DE

Spider silk is a highly interesting material with outstanding properties. Because the usage of natural spider silk for technical applications is not possible, the production of recombinant spider silk was established. This production process has [...]

Recent Results from Gas Loaded Nanoparticle-Type Cluster Power Units

Miley G.H., Kim K-J, Patel T.C., Lenuco LLC, US

This research is done in support of the development of modular 5 kW co-generation power LENR cells by LENUCO LLC. These modular units are stacked to provide powers up to 50 kW. A prototype unit [...]

Design and Testing of a High-Efficiency Hydrokinetic Turbine

Richard White E., Ferguson F.D., Asterita A.J., ViGYAN, Inc., US

There are numerous situations in which electrical power is required for remote locations not served by utilities or where existing electrical service is compromised. This paper addresses the feasibility of power extraction from local supplies [...]

A new strategy of using unstable offshore wind power by combination with pumped storage generation with reversible pump turbine

Zhai Y., Ma J., Mitobe M., Uehara S., Gon S., Sugawara A., Niigata University, JP

The cost of wind energy resources are low and it is abundant, with a characteristic of the energy saving and eco effect. But if large-scale wind power be merged into the power network directly, the [...]

Enhancement of GaAs solar cell efficiency by type-II GaSb quantum dots located outside of the depletion region

Kechiantz A., Afanasev A., Lazzari J.-L., The George Washington University, US

Experiments have shown that extrinsic intermediate band (IB) states, for instance, formed by artificial quantum dots (QDs), located in the depletion region participate in electron-hole recombination. This facilitates dramatically the dark current and reduces the [...]

A Focused Super-Continuum Solar Simulator for Illuminated Solar Cell Microscopy

Dennis T., National Institute of Standards and Technology, US

The design and application of a novel, focused solar simulator based on a high-power, super-continuum laser is described. We used the simulator to create micrometer-scale spatial maps of full-spectrum optical beam induced current (FS-OBIC) in [...]

Water Splitting for H2 Production using Visible-light-responsive Photocatalysts

Huang J., Zhang G., Zhang W., Zhang G., Zhang W., Wang P., Minakata D., Chen Y., Crittenden J., New Jersey Institute of Technology, US

Hydrogen (H2) production using visible-light photocatalysis for water splitting has attracted considerable attention owing to the growing demand for environmentally friendly and sustainable energy sources. This presentation will demonstrate our previous study on H2 production [...]
