New efficiency benchmark for dye-sensitized solar cells
In a paper published online June 29 in the journal Nature Materials, EPFL professor Michael Graetzel, Shaik Zakeeruddin and colleagues from the Changchun Institute of Applied Chemistry at the Chinese Academy of Sciences have achieved a record light conversion efficiency of 8.2% in solvent-free dye-sensitized solar cells.

Desalination can boost US water supplies, but environmental research needed
Recent advances in technology have made removing salt from seawater and groundwater a realistic option for increasing water supplies in some parts of the U.S., and desalination will likely have a niche in meeting the nation's future water needs, says a new report from the National Research Council.

Carbon nanotubes made into conductive, flexible 'stained glass'
Carbon nanotubes are promising materials for many high-technology applications due to their exceptional mechanical, thermal, chemical, optical and electrical properties. (2008-04-09)

New aluminum-rich alloy produces hydrogen on-demand for large-scale uses
Purdue University engineers have developed a new aluminum-rich alloy that produces hydrogen by splitting water and is economically competitive with conventional fuels for transportation and power generation. (2008-02-20)

Transporters may help delay diabetes-related retinal damage
Two transporters that deliver alternative energy sources to the eye may help delay retinal damage that can occur in diabetes, researchers say. (2007-11-29)

Clemson physicist addresses international forum on thermoelectric energy
Energy lost from hot engines could save billions of dollars if it could be captured and converted into electricity via thermoelectric devices, Clemson University physicist Terry Tritt told scientists gathered in Dallas for the world-renowned NanoTX '07 conference. (2007-10-04)

Engineered eggshells to help make hydrogen fuel
Engineers at Ohio State University have found a way to turn discarded chicken eggshells into an alternative energy resource. The patented process uses eggshells to soak up carbon dioxide from a reaction that produces hydrogen fuel. It also includes a unique method for peeling the collagen-containing membrane from the inside of the shells, so that the collagen can be used commercially. (2007-09-27)

Palladium and platinum an easier find with Pitt researcher's detection method
Finding uses for palladium and platinum--rare precious metals coveted by the automobile, chemical, and pharmaceutical industries as catalysts in chemical reactions-proves easier than finding the scarce materials themselves. (2007-09-24)

Trade-offs reveal no clear favorites in alternative energy market
The nuclear power industry is riding the green wave back into public favor with its promise of a low-carbon solution to our growing energy needs. But even as the industry struggles to dictate what role nuclear can realistically play, it is bound by a global energy landscape-from solar to carbon sequestration-that is still predominantly shaped by the marketplace.

Adding up renewable energy
Do the overall efficiencies of renewable energy sources, such as wind, solar, and geothermal add up in terms of their complete life cycle from materials sourcing, manufacture, running, and decommissioning" Researchers in Greece have carried out a life cycle assessment to find the answer.
