Superconductivity Explained via Hemp Cellulosic Graphene

Cellulosic GrapheneWhile researching and trying to figure out why hemp graphene is such a good conductor on a par with carbon nanotubes, I found this gem of an article which nicely explains superconductivity. I was looking for some research about cannabis hemp graphene and it’s “dis-ordered distribution of cooper pairs” or something… these are the pairs of electrons that need to move together if you want to maintain superconductivity! Regular superconductors loose it due to heat disturbing the movement of these pairs of electrons. It seems that hemp graphene mite be able to be processed to perform like graphene.

 

So what about hemp graphene? Does it super-conduct?

Yes. In this interesting article we get:

As hemp makes a comeback in the U.S. after a decades-long ban on its cultivation, scientists are reporting that fibers from the plant can pack as much energy and power as graphene, long-touted as the model material for supercapacitors. They’re presenting their research, which a Canadian start-up company is working on scaling up, at the 248th National Meeting & Exposition of the American Chemical Society (ACS), the world’s largest scientific society.

“Our device’s electrochemical performance is on par with or better than graphene-based devices,”

“Hemp bast is a nanocomposite made up of layers of lignin, hemicellulose, and crystalline cellulose. If you process it the right way, it separates into nanosheets similar to graphene.”

This would make a much cheaper source of high-carbon tubing than pure-carbon ones: From one source I picked totally at random –  this tubing is $258 per gram or these nice looking Silver Nanowires 30nm OD at $200-$500/gram.

 

This means that if two electrons forming a Cooper pair go from the superconductor to the normal metal, they have to stay in the same quantum state while they go through the normal metal in order to be able to form a superconducting pair in the second superconductor. Hence, the paired electrons have to be subjected to the same interactions while going through the “normal” metal, and their state must not change because of thermal agitation or an interaction with a magnetic atom that would affect the two electrons of the pair differently.
