However, past attempts to make hexagon-lattice synthetic diamonds have resulted in diamonds that were too small and of low purity. In this new effort, the research team tried a different approach.

Graphene consists of a single layer of carbon atoms arranged in a hexagonal lattice, all sp 2 hybridized, giving it remarkable strength, flexibility, and electrical conductivity. More generally, and ...

(Image: Empa) Graphene nanoribbons are narrow strips of graphene, a single layer of carbon atoms arranged in a hexagonal lattice. GNRs can have different edge structures, such as armchair or zigzag, ...
