Lee Rannals for redOrbit.com - Your Universe Online Scientists have succeeded in creating a new material that is capable of generating hydrogen, producing clean water and creating energy. Nanyang Technological University (NTU) researchers created a single nanomaterial that can be used as a flexible water filtration membrane, to help recover energy from desalination waste brine, be made into flexible solar cells, and can double the lifespan of lithium ion batteries. The Multi-use...

Light-based Hydrogen Production Substantially Improved
2012-11-09 08:56:20

[ Watch The Video ] University of Rochester Hydrogen is an attractive fuel source because it can easily be converted into electric energy and gives off no greenhouse emissions. A group of chemists at the University of Rochester is adding to its appeal by increasing the output and lowering the cost of current light-driven hydrogen-production systems. The work, funded by the U.S. Department of Energy, was led by chemistry professors Richard Eisenberg, Todd Krauss, and Patrick Holland,...

Many organic contaminants in the air and in drinking water need to be detected at very low-level concentrations. Research published by the laboratory of Prashant V. Kamat, the John A. Zahm Professor of Science at the University of Notre Dame, could be beneficial in detecting those contaminants. The Kamat laboratory uses Surface-Enhanced Raman Spectroscopy to make use of silver nanoparticles to increase the sensitivity limit of chemical detection. Researchers in this study have prepared a...
