To view more programmes in this series visit http://vega.org.uk/video/subseries/27 In October 2010 the Nobel Prize for Physics was won by Andre Geim and Constantin Novoselov at Manchester University for their work on graphene "for groundbreaking experiments regarding the two-dimensional material graphene" but if you are left wondering just what graphene is then watch this video. Jonathan explains all.

@kunschner IT would be light and strong enough but it won't be possible at the
moment because can't make sheets large enough - people are working on
mixing it into composites but again it's a bit early days, worth a try
in a year or two?

@VegaScienceTrust Its obvious he quotes them - (notice the ' " ' )

True, True!

dont think that i is not that conductive. 1 cm on a piece of paper has lie...2300 kOhms!

you're a good teacher ! liked it

Your talking with high dynamic range is hard to listen to. One moment you're whispering, the next you're shouting.

@VegaScienceTrust Yeah, I've read that there are work-arounds, but, I was just posting that to prove i wasn't crazy and that i wasn't making stuff up in my head from before. =p

I only see 3 bonds to every carbon. Shouldn't there be 4 bonds to create an octet?
sk8ross 1 week ago
@sk8ross Yes that's right - the carbon atom uses three of its bonding electrons
to form 3 strong bonds, each with one of its neighbours, and its
fourth electron forms a distributed bond (a delocalised pi-bond for
the specialists!) that spreads out over the surface of the graphene
sheet and gives it its semi-metallic character.

@VegaScienceTrust I see now. So the carbons have the three strong bonds and partial double bond to give the octet. The double bond character creates conjugation so the electrons can spread throughout the molecule. This allows graphene to be such a great conductor? Did I get that right?

@sk8ross bingo! :-)
