Their Nobel for Graphene Today, Your Products Tomorrow

GRAPHENE!This picture is not chicken wire or a tesselation or a patchwork quilt or a cross-section of a honeycomb-amazing how many things are linked hexagons-but a material called graphene, which is just plain old pencil-lead graphite sliced thin, sliced as thin as you could imagine thin could be. It's thin enough that electricity flows through it effortlessly. It's thin enough to see through. It's one atom thin. Those atoms are carbon and their little arms hold tight and so in spite of being thin, it's also flexible and strong. Its possible applications are making the technoratiat fall all over itself with joy and lust. It just won its discoverers, Andre Geim and Konstantin Novoselov, the physics Nobel Prize.

Geim and Novoselov, at the University of Manchester in the UK, made the first sample of graphene-that wasn't made by everybody else writing with a pencil on paper-by peeling a layer of it off a chunk of graphite with Scotch tape. Graphite is a three-dimensional honeycomb; a one-millimeter chunk of graphite is actually a stack of three million layers of graphene. The layers peel off easily; all the strength is in the flat layer, in two dimensions. You can roll a layer into a nanotube; you can wad a layer into a buckyball. Graphene's strength, plus its transparency, flexibility and ability to conduct electricity, are ideal for making transistors, touch screens, sensors and roll-up computer monitors which, being thin as paper, could-I make a wild surmise-be bound into books.

Geim and Novoselov are young, 51 and 36 respectively, giving them plenty of time to develop the Nobel effect and become so famous they stop doing research and spend the rest of their lives giving talks and having opinions. Geim says he won't: "I'll just try to muddle on as before." Ten years ago, he won another prize, called the Ig Nobel, for magnetically levitating a frog.

This Nobel for physics, like most of them lately, is in a field called condensed matter, formerly called solid state, which is famous for having applications, attracting money and being completely incomprehensible. It bores me to pieces, I really can't abide it, but something about reducing reality to two dimensions makes my inner philosopher want to jump around all over the place.

Where can I get me on of them levitatin' frogs?

Hooray! Does this mean the space elevator is right around the corner?

SourCapote (#4,872)

so yea um hmmmm

Shit's DOpe!!

petejayhawk (#1,249)

Well said, Wes. Well said.

MollyculeTheory (#4,519)

I am going to start sticking scotch tape on random things, peeling it off, and sending it all to Sweden, JUST IN CASE.

lawyergay (#220)

Nice. I would recommend starting with that film on the bottom of your cat's wet-food bowl.

barnhouse (#1,326)

They got the prize for getting the stuff OFF the Scotch tape. (HOW?)

Joey Camire (#6,325)

Could we use Technotariat instead?

Also- Cool.

lawyergay (#220)

I know that this is supposed to be "strong" and everything, but couldn't a single-atom thin piece of ANYTHING be ripped into atomic shreds by a human being? Or even a cat?

I don't care if I can't see it. HULK SMASH.

deepomega (#1,720)

ESPECIALLY a cat. Jesus christ, fucking cats.

Nope! From the always-reliable Wikipedia:

In 2000, a multi-walled carbon nanotube was tested to have a tensile strength of 63 gigapascals (GPa).[17] (This, for illustration, translates into the ability to endure tension of a weight equivalent to 6422 kg on a cable with cross-section of 1 mm2.)

Wow! Okay…I feel better about this particular Nobel Prize.

Memo to Oslo: I'm good.

Annie K. (#3,563)

I think "strong" is relative. For instance, the Nobel people also explained that a one-meter graphene hammock, which would weigh as much as a cat's whisker, would hold a four-kilogram cat before it broke. http://bit.ly/acHrxk

Also I want to add that the frog video was Choire's idea. I have my standards.

But what of the space elevator??

lawyergay (#220)

Aha! Cats do break things! HULK SMASH.

I wouldn't be holding my breath for a space elevator any time soon. Realistically, there are a huge number of technical issues that would need to be worked out first – most immediately, the problem is that we don't know how to make carbon nanotubes of sufficient length to actually build a cable out of (the longest ever made was on the order of about a foot, and more practical processes produce tubes of around a millimeter in length). So far the research into actually making long tubes has not been promising. And even if that problem is solved, there are numerous others.

My own opinion is that a space elevator is not likely to be economically viable any time in the near future.

Abe Sauer (#148)

Buckminsterfullerenes!

BadUncle (#153)

If graphene is so strong, why do my pencils keep breaking?

also? I don't see how anything that small can be photographed. I suspect…tilt shifting!

SeanP (#4,058)

Quick answer: graphene!=graphite. Graphene is a single sheet of carbon atoms in that hexagon-shaped layout. Graphite is lots of bits of graphene stuck together in random orientations. These bits tend to fall apart pretty easily. Consider a solid quartz crystal and a chunk of sandstone – both are more or less pure silicon dioxide (admittedly the sandstone is less so), but the quartz crystal is very hard and strong, whereas sandstone can be pretty crumbly. It's the same situation w/ graphite vs. graphene.
