In 2015, American consumers will finally be able to purchase fuel cell cars from Toyota and other manufacturers. Although touted as zero-emissions vehicles, most of the cars will run on hydrogen made from natural gas, a fossil fuel that contributes to global warming.

Now, scientists at Stanford Univ. have developed a low-cost, emissions-free device that uses an ordinary AAA battery to produce hydrogen by water electrolysis. The battery sends an electric current through two electrodes that split liquid water into hydrogen and oxygen gas. Unlike other water splitters that use precious-metal catalysts, the electrodes in the Stanford device are made of inexpensive and abundant nickel and iron.

A promising new application of graphene has been described by researchers at MIT, Columbia University and IBM's T. J. Watson Research Center in the latest issue of Nature Photonics. It has been revealed that graphene in photo detectors could convert optical signals to electrical signals in integrated optoelectronic computer chips.

Light will be used by them instead of electricity to move data both within and between computer chips. This could drastically reduce the power consumption and heat production. These are the problems to engulf with increase in computational capacity.
