Graphene could yield cheaper optical chips

Graphene—which consists of atom-thick sheets of carbon atoms arranged hexagonally—is the new wonder material: Flexible, lightweight and incredibly conductive electrically, it's also the strongest material known to man.

Unzipped nanotubes unlock potential for batteries

( —Researchers at Rice University have come up with a new way to boost the efficiency of the ubiquitous lithium ion (LI) battery by employing ribbons of graphene that start as carbon nanotubes.

Memory effect now also found in lithium-ion batteries

Lithium-ion batteries are high performance energy storage devices used in many commercial electronic appliances. Certainly, they can store a large amount of energy in a relatively small volume. They have also previously been ...
