graphene – a single layer of carbon, one atom thick

(pronounced gra-feen)

To remember the meaning of graphene, use the following mnemonic:

I grabbed the fiends (graphene) who had each taken a single layer of the carbonated (carbon) beverages. 

Graphene is a form of carbon consisting of a single layer of carbon atoms arranged in a lattice structure, similar to a honeycomb pattern. Each carbon atom in graphene is bonded to three other carbon atoms through strong covalent bonds. This gives it remarkable properties, including exceptional strength (it's about 200 times stronger than steel), excellent electrical and thermal conductivity, and being extremely thin yet flexible. These properties make graphene useful for potential applications in electronics, materials science, and nanotechnology.
