[Nanomaterials] – Research reveals exotic quantum states in double-layer graphene 26 juin 2019

Researchers from Brown and Columbia Universities have demonstrated previously unknown states of matter that arise in double-layer stacks of graphene, a two-dimensional nanomaterial. These new states, known as the fractional quantum Hall effect, arise from the complex interactions of electrons both within and across graphene layers.

[Graphene] – Graphene and the Most Popular Advanced Alloys 3 novembre 2020

Graphene is an extraordinary material, the only basic member of a family of 2D carbon materials. With its unique mechanical and physical properties, it is a superb filler at the nanoscale, in metal matrix composite materials. It can easily disperse into the matrix and is cheaper than its closest competitor, carbon nanotubes, which enhance strength and function. The increased surface-to-volume ratio of graphene also means that its properties are better reflected in the composite.
