A group of scientists from Russia, USA and China used computer generated simulations to predict the existence of a new 2D carbon material, a "patchwork" analogue of graphene called phagraphene. Unlike graphene, phagraphene consists of penta-, hexa- and heptagonal carbon rings and its name is made of a contraction of Penta-Hexa-heptA-graphene. 

Phagraphene is expected to share many of the same properties with graphene. The researchers say that in phagraphene, due to the different number of atoms in the rings, some properties are predicted to be different and that it would be interesting to see where it might be useful.
