Weyl fermions

An article published in the July 2015 edition of Science, show the discovery of Weyl fermions by an international team lead by Princeton University scientists. Weyl fermions are massless particles, predicted back in 1929 by Hermann Weyl. These fermions can be crucial for the continuous development of electronic circuits, performing a lot faster than the electronics today. What is even more interesting, is that while graphene is a 2D material, Weyl fermions should exists in a 3D environment, which opens for more practical applications “in real life”.

Could graphene be used to extract lithium from seawater?

More and more electric vehicles hitting the road could strain the world’s lithium supply, and today only natural processes are used commercially to extract lithium from high-concentration salt water an article from MIT Technology Review states – Quest to Mine Seawater for Lithium Advances.

The solution could be graphen a company called G2O Water thinks, using graphene oxide to create their membrane and thus reduce the fouling of the membrane over time.
