• Graphene supercapacitor holds promise for portable electronics
• Implanted Biofuel Cell Operating in Living Snail
• Researchers create more efficient hydrogen fuel cells

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.

• Barrier to faster graphene devices identified and suppressed
• Hydrogen power in real life: Clean and energy efficient
• Artificially structured metamaterials may boost wireless power transfer

Barrier to faster graphene devices identified and suppressed Posted: 13 Mar 2012 03:52 PM PDT Physicists report that they have nailed down the source of the interference inhibiting the rapid flow of electrons through graphene-based devices and found a way to suppress it.

Hydrogen power in real life: Clean and energy efficient Posted: 13 Mar 2012 09:15 AM PDT Since 2009, a hydrogen powered street cleaning vehicle has been undergoing testing on the streets of Basel. The project is intended to take hydrogen drives out of the laboratory and onto the streets in order to gain experience on using them under practical conditions. The result of the pilot trial: hydrogen as a fuel for municipal utility vehicles saves energy, is environmentally friendly and is technically feasible. In order to make it cost-effective, however, the prices of fuel cells, pressurized storage tanks and electric drives must all drop significantly.

Artificially structured metamaterials may boost wireless power transfer Posted: 12 Mar 2012 04:27 PM PDT More than one hundred years after the pioneering inventor Nikola Tesla first became fascinated with wireless energy transfer, the spread of mobile electronic devices has sparked renewed interest in the ability to power up without plugging in. Now researchers have proposed a way to enhance the efficiency of wireless power transfer systems by incorporating a lens made from a new class of artificial materials.
