Unzipping Nanotubes Makes Superfast Electronics
Al writes "Two research groups have found a way to unzip carbon nanotubes to create nanoribbons of graphene — a material that has shown great promise for use as nanoscale transistors, but which has proven difficult to manufacture previously. A team led by James Tour, a professor of chemistry and computer science at Rice University, and another led by Hongjie Dai, a professor of chemistry at Stanford University, both figured out ways to slice carbon nanotubes open to create the nanoribbons. The Stanford team was funded by Intel, and the Rice group is in talks with several companies about commercializing their approach."
Hey, that's what an ex-girlfriend of mine called it: her nano-tube. Bitch. Oh, carbon nano-tubes.....gotta hit Cancel.
Strangely aroused by the title.
Almost made me RTFA.
Almost....
Oops, sorry, meant to post it to a different article!
Isn't it obvious if a molecule is a cylinder cage, and you take out a line... it makes a flat surface?
Unzipping...
She did say you were pretty quick.

So now we have a method to bulk-produce graphene; but do we have a way to implement it in devices?
In any case, this is good. Nanowire diameter shouldn't be that hard to manipulate. The more you can manipulate something in synthesis for functional properties, the better it is for application. Look at doping silicon for example.
In any case, I wonder what the lifetime of a graphene-based device would be. Molecular compounds aren't always the most stable. That's one of the main reasons that they are being held back from adoption.
I have left slashdot and am now on Soylent News. FUCK YOU DICE.
I rtfa and I saw mention of nanoribbons, but nothing about nanoribbens. Obviously Al doesn't know what he's talking about since he's just making up new words on the fly.

Your girlfriend also said i was quick!
oh wait this is /.....

Won't a stray cosmic ray cause my cpu to fall over?
Like all pain, suffering is a signal that something isn't right
Sounds like just what I need to tie up my nanopresent after wrapping it in nanopaper, covered with nanowhimisicaldecorations!
Two words:
Nanoitching powder.
It practically sells itself!

Both these groups have succeeded where many others have tried and failed (even with very similar ideas). It's great work. As the summary suggested though, they've taken one hard to work with material and using a complicated process, made an even harder to work with material. This is great for doing science, as graphene ribbons are a huge pain to make, and this should open up more labs to investigating their properties.
If we're going to have graphene consumer electronics though, it's going to be based on the wafer-scale CVD manufacturing process developed in Korea and MIT.
It's really funny, but it seemed like the nanotubes themselves were pretty hard to make not too long ago. Then, as of last year, I find they are down to $150/kg and are working their way into all sorts of consumer applications.
This is my sig.
Cool. They've found something small enough to map the minds of celebrities onto. One more order of magnitude, they'll have something appropriately sized for a politician's mind.
But if they unzip them, the emails fall out! OH THE HUMANITY!

I work in the graphene area, and I think this is bullshit. First, graphene nanoribbons created using this method do not address the fundamental issues that accompany using carbon nanotubes such as targeted orientation or chirality concerns. This is a clear case of missing the forest for the trees. Second, Dai is known for some rather unbelievable studies.
Well about 99% of the time that would be a GOOD thing....
"And again, the internet is not something you just dump something on. It's not a truck. It's a series of [nano]tubes" Wow this time it would actually make sense.
All hail the inanimate carbon rod!
Hmm, as I recall my High School terror^H^H^H^H^H^Hchemistry classes, that produces Manganese Heptoxide.
