Graphene: What is it, anyway?

Clever people have managed to extract single-atom-thick layers of graphite. (Graphite is made from “sheets” of carbon atoms arranged in a hexagonal pattern). They are calling this as-near-to-2D-as-you-can-get material “graphene”. So what? you ask. Well, it’s 100 times stronger than steel (a sheet the thickness of Gladwrap could support an elephant!), conducts electricity better than copper, and might one day displace silicon from computer chips. Graphene can also be used to protect sensitive sensors and devices from laser damage, and for optical circuits. So, a bit useful.

You can watch a little video about it over at Scientific American.
