Graphene gives boost to Edison's Nickel-Iron battery

Graphene has been used to revive a rechargeable battery technology invented by Thomas Edison (yes, that Thomas Edison) more than 100 years ago in a collision of technologies that could prove very fruitful.Edison’s idea was that the batteries would power electric vehicles, but the largely technology fell out of use in the 1970s, because although it is very durable, the charge and discharge times are very slow.

Looking at single atoms of hydrogen

As you probably know, graphene is a one-atom-thick sheet of carbon atoms packed in a dense two-dimensional honeycomb lattice. And it recently became very popular recently as a basis for ultra-fast transistors. Now, according to Science News, U.S. researchers are using graphene to image individual hydrogen atoms via a standard transmission electron microscope (TEM) technology. Until now, heavy atoms, such as carbon, could be detected by electron microscopy. But the physicists from Berkeley, California, have shown it's possible to track the smallest atoms, hydrogen ones. But read more...
