If you haven't heard of it before, you have now. And it may prove to be the next big thing in materials science. SciShow explains what it is, why it's so awesome, and what challenges we face...
========== Graphene: everybody's talking about it. When
hearing some of its basic properties, youmight have wondered if people were confusing
it with some kind of substance only foundin comic books. It's one atom thick, conducts
electricity better than silver, conducts heatbetter than diamond, and it's stronger than
steel. It would take the focused force ofan elephant balancing on a pencil point to
pierce through a piece of graphene as thickas plastic wrap.And yet, graphITE is made of the same stuff.
And yeah, that crumbly stuff used to makeyour pencil is a lot less impressive. So what's
up? Graphene is made of carbon, and carbonhas only two naturally occurring crystalline
structures; graphite, which is just stacksand stacks of graphene piled on to...
