Graphene Can Be Made With Table Sugar

Zothecula writes with this snippet from Gizmag: "There's no doubt that the discovery of graphene is one sweet breakthrough. The remarkable material offers everything from faster, cooler electronics and cheaper lithium-ion batteries to faster DNA sequencing and single-atom transistors. Researchers at Rice University have made graphene even sweeter by developing a way to make pristine sheets of the one-atom-thick form of carbon from plain table sugar and other carbon-based substances. In another plus, the one-step process takes place at temperatures low enough to make the wonder material easy to manufacture."

On a side note, scotch tape releases x-rays when you peel it: http://www.wired.com/science/discoveries/multimedia/2008/10/gallery_xray_tape?slide=1&slideView=7 [wired.com]

Sweet

Now all we need is to figure a way to get all the cabon-laden pollution to be recycled into graphene and we'll be all set. How plausible would that be once the technology is refined enough?

Re:How much does the USPTO cost?

[TheRaven64]

The US patent office does not get to keep patent fees. They go into the general budget and then some percentage is returned by the federal government. This percentage may be greater than 100%, in which case they'd be costing money, but given that they go up to tens of thousands of dollars for patents more than a decade old it seems unlikely.

I'm lucky enough to actually do research on graphene, this method is still used (albeit carefully and in a clean room so it's not as flippant as it sounds).

Single Atoms?

[Ramble]

Single atom transistors? Where are they getting this from? I do work with graphene and to introduce a bandgap (either in single or multilayer sheets) you need to introduce an energy difference between atoms - in the case of a single sheet you do that by using a substrate with a similar structure (e.g. Boron nitride) so the two basis atoms of graphene experience different energies or in the case of multiple sheets you can use an electric field ala FETs. In no way could you do this with a single atom as graphene has no band gap and is thus a metal normally.

Re:DIY?

[marcosdumay]

You can make it at home, but an 800C furnance may be more expensive than you think (but still within reach of an individual). You'll probably no be able to do anything usefull with it (on a 3D printer or anywhere else).
