Off-grid sterilization with nanotechnology 'solar steam' system (w/video)

Rice University nanotechnology researchers have unveiled a solar-powered sterilization system that could be a boon for more than 2.5 billion people who lack adequate sanitation. The 'solar steam' sterilization system uses nanomaterials to convert as much as 80 percent of the energy in sunlight into germ-killing heat.

In nanomaterials, the structure of the individual crystals changes with grain size

The properties of nanomaterials could be easier to predict in future. Scientists have ground metal into continuously finer powders in steps and prepared a detailed catalogue of how the structure of the metal grains changes depending on grain size. They discovered that the crystal lattices initially shrink, but expand again below a certain threshold grain size.

Hydrogen cars quickened by Copenhagen chemists

Climate friendly fuel cells for hydrogen cars have come one step closer. Researchers at the Department of Chemistry, University of Copenhagen, have shown how to build fuel cells that produce as much electricity as current models, but require markedly less of the rare and valuable precious metal platinum.

Paper-thin e-skin holds promise for robotics (w/video)

A research team led by Ali Javey, UC Berkeley associate professor of electrical engineering and computer sciences, has created the first user-interactive sensor network on flexible plastic. The new electronic skin, or e-skin, responds to touch by instantly lighting up. The more intense the pressure, the brighter the light it emits.
