After 16 years of hype, graphene finally delivers on its promise – with a cosmetic face mask

It is a polycyclic aromatic hydrocarbon, after all ...

No, it is not. Graphene is a single layer of carbon atoms, organized in a hexagonal lattice that forms a two-dimensional sheet. It is 100% carbon, so cannot be described as an aromatic hydrocarbon.

- ex-chemist, who wrote his MSc thesis on graphite intercalation compounds.

Intercalation compounds are graphite structures with a layer of an inorganic compound, e.g. Ferric chloride, FeCl3, in between adjacent sheets of carbon. We'd now call those sheets graphene, but that word wasn't used until Andre Geim and Konstantin Novoselov peeled those carbon layers apart and decsribed them in 2004.
