Graphene is an allotrope of carbon consisting of a single layer of atoms arranged in a hexagonal lattice nanostructure. The name is derived from "graphite" and the suffix -ene, reflecting the fact that the graphite allotrope of carbon contains numerous double bonds. Each atom in a graphene sheet is connected to its three nearest neighbors by a strong σ-bond, and contributes to a valence band one electron that extends over the whole sheet. This is the same typ… WebApr 11, 2024 · calligraphy, the art of beautiful handwriting. The term may derive from the Greek words for “beauty” ( kallos) and “to write” ( graphein ).
