A snap shot from molecular dynamics calculations showing how an iron particle (pink) ingests carbon atoms (blue) from a graphene surface below is shown. The process results in the creation of holes in the graphene sheet and the formation of “holey graphene”. As reported by Mauricio Terrones and co‐workers on page 76 , the calculations explain how iron particles can catalyze the formation of holes in graphene by a low energy electron beam using an aberration‐corrected high‐resolution transmission electron microscope.
