Bob,
I'm sure you're familiar with this, but this blog is the first I've heard of it.
More info is on the CAFE Blog at http://blog.cafefoundation.org/?p=2439.

Thin, Light, Strong, and Energy Dense
by Dean Sigler on 01/07/2011
2010’s Nobel Prize in Physics went to Andre Geim and Konstantin Novoselov, who extracted graphene from a piece of graphite when they stuck a piece of adhesive tape to it and peeled away a single atom-thick layer of the thinnest, strongest material in the world.
The Nobel Prize web site explains other remarkable properties of this new material. “As a conductor of electricity it performs as well as copper. As a conductor of heat it outperforms all other known materials. It is almost completely transparent, yet so dense that not even helium, the smallest gas atom, can pass through it. Carbon, the basis of all known life on earth, has surprised us once again.”
When mixed into plastics, graphene can turn them into conductors of electricity while making them more heat resistant and mechanically robust.
Over 28,000 square feet per gram for a single layer of the material – or about the size of a football field

I think there is a typo there... I believe they mean to say, “Even helium the smallest gas atom, cannot pass through it”.
Also isn’t hydrogen smaller than helium? One electron is smaller than two on the atomic level. However on a molecular level it’s true. Helium being inert is He. Hydrogen being so active is H2 a lot larger.

OK, that's the second time I've heard about this stuff in 24 hours... so, if you want an entertaining survey of modern materials (including a demonstration of graphene production) check this out:
http://www.pbs.org/wgbh/nova/tech/making-stuff.html
I expected less from this NOVA series but was entertained and informed throughout the first 2 shows.
