Carbon Nanotubes Help Energize Fuel Cells and Metal-Air Batteries
Posted in News, News, Batteries, Energy Storage, Alternative Fuels on Monday, 25 June 2012
Fuel cells, which use chemicals to create electricity, hold promise in a variety of areas but the high price of platinum catalysts used inside the cells has provided a roadblock. One promising low-cost alternative to platinum is the carbon nanotube – an excellent conductor of electricity. Multi-walled carbon nanotubes riddled with defects and impurities on the outside could eventually replace some of the platinum catalysts used in fuel cells and metal-air batteries, according to Stanford University scientists.

Coaxial Nanocable Could Aid in Energy Storage
Posted in News, News, Batteries, Electronic Components, Energy Efficiency, Energy Storage on Friday, 08 June 2012
Researchers at Rice University have created a coaxial cable that is about a thousand times smaller than a human hair and has higher capacitance than previously reported microcapacitors. The nanocable was produced with techniques pioneered in the burgeoning graphene research field and could be used to build next-generation energy-storage systems.

Boosting Nanowires for Better Batteries and Solar Cells
Posted in News, News, Batteries, Energy Storage, Renewable Energy, Solar Power, Alternative Fuels on Tuesday, 01 May 2012
Stanford University engineers have found a novel method for "decorating" nanowires with chains of tiny particles to increase their electrical and catalytic performance. The technique is simpler and faster than earlier methods and could lead to better lithium-ion batteries, more efficient thin-film solar cells, and improved catalysts that yield new synthetic fuels.

Using Electricity to Generate Alternative Fuel
Posted in News, News, Batteries, Energy Storage, Solar Power, Alternative Fuels, Greenhouse Gases on Friday, 30 March 2012
Electrical energy generated by various methods can be difficult to store efficiently. Chemical batteries, hydraulic pumping, and water splitting suffer from low energy-density storage or incompatibility with current transportation infrastructure. UCLA researchers have demonstrated a method for storing electrical energy as chemical energy in higher alcohols, which can be used as liquid transportation fuels.
