Can you believe we have been burning this miracle substance for fuel???!!!

The most power and mysterious config we know of for carbon and it is everywhere!!

Though it is early days in the study of such devices, the practical upshot of this research may be in the eventual production of novel types of ultrafast and extremely effective photodetectors and energy-harvesting devices. And, given that the basic operating principles of hot-carrier graphene devices are substantially different from traditional silicon or germanium semiconductors, an entirely new stream of electronic components that take advantage of this phenomenon may evolve.

The findings of this work have recently been published in the journal Nature Nanotechnology.

Graphene has been around for a while. It often takes a while to implement new material technologies. That entire sector, material technologies is evolving rapidly. If I remember correctly, there were safety issues with regard to exposure being poisonous in some ways. I can't remember exactly why.

Perhaps you are thinking of Benzene, which has a similar structure to graphene (hexagonal lattice).

Yeah graphene is just a single layer of graphite aka carbon.

Back when I was in undergrad I read an article in a journal about it. The problem was the lack of a viable method of creating grapene. The author was basically having to use scotch tape on graphite to extract a single layer of carbon and then do the best they could to get it off the tape lol

This was around 2009

Boyd, a researcher in the Physics, Mathematics & Astronomy division at Caltech, says his method can burn at half the temperature and produce graphene with up to twice the quality of the second method. Oh, and do it all in five minutes. The research is outlined in Nature Communications.

His way uses only a small amount of methane gas, which splits into hydrogen and carbon when it reacts with the copper (a process Boyd smooths out by adding a nitrogen compound. At the same time, nitrogen added to the mix also reacts with the copper and smooths it surface, making it easier for high-quality graphene to form there. Heat is provided via plasma burning at about 420 degrees Celsius. At the end of the process there's a sheet of graphene left from the reaction with copper. In that way, Boyd's process is similar to the most advanced existing methods. But he says his product is 60,000 cm^2/(V s) and takes just a fraction of the time.
