Graphene supercapacitor holds promise for portable electronics Posted: 15 Mar 2012 12:25 PM PDT Researchers have used a standard LightScribe DVD optical drive to produce electrodes composed of an expanded network of graphene that shows excellent mechanical and electrical properties as well as exceptionally high surface area. These LSG supercapacitors demonstrate high-performance graphene-based electrochemical capacitors that maintain excellent electrochemical attributes under high mechanical stress and may be ideal energy storage systems for next generation flexible, portable electronics.

Implanted Biofuel Cell Operating in Living Snail Posted: 15 Mar 2012 11:50 AM PDT Researchers have implanted a biofuel cell in a living snail. This is the first incidence of an implanted biofuel cell continuously operating in a snail and producing electrical power over a long period of time using the snail's physiologically produced glucose as a fuel.

Researchers create more efficient hydrogen fuel cells Posted: 15 Mar 2012 08:04 AM PDT Hydrogen fuel cells, like those found in some "green" vehicles, have a lot of promise as an alternative fuel source, but making them practical on a large scale requires them to be more efficient and cost effective. Scientists may have now found a way around both hurdles.
