The Magic Angle of Twisted Graphene
Université Catholique de Louvain / Phys.org / February 23, 2021

Graphene, a two-dimensional material composed exclusively of carbon, has revealed extraordinary properties, including thermal and electrical conductivity, transparency, and flexibility. When combined, these properties become particularly interesting in the age of touch screens and flexible electronics. “Unlike 3-D materials, graphene has a height reduced to the ultimate dimension of the atom. It’s therefore a carbon atom plane,” explains Prof. Jean-Christophe Charlier, a specialist in nanoscopic physics at the Institute of Condensed Matter and Nanosciences of UCLouvain.

“When two layers of graphene are superimposed with this magic angle, they give rise to superconductivity. They therefore conduct electricity without any resistance,” Prof. Charlier says.

This property is more than useful for transporting electricity without loss of energy.

Of course, all this will be moot once Greta gets rid of carbon.

Graphene Water Filter Turns Whisky Clear
University of Manchester / November 14, 2017

Prof. Nair said, “Just for a fun, we even filtered whisky and cognac through the graphene-oxide membrane. The membrane allowed the alcohol to pass through but removed the larger molecules, which gives the amber colour. The clear whisky smells similar to the original whisky but we are not allowed to drink it in the lab, however it was a funny Friday night experiment!”
