Graphene's strength lies in its defects

Materials engineers at Brown University have found that the juncture at which graphene sheets meet does not compromise the material's strength. These so-called grain boundaries are so strong, in fact, that the sheets are nearly as strong as pure graphene. The trick lies in the angles at which the individual sheets are stitched together.

Researchers clarify reaction pathway to fabricate graphene-like materials

Graphene is a promising material for tomorrow's nanoelectronics devices. Precise and upscaleable methods to fabricate graphene and derived materials with desired electronic properties are however still searched after. To overcome the current limitations, Empa researchers have fabricated graphene-like materials using a surface chemical route and clarified in detail the corresponding reaction pathway.
