Amazing stuff!
"... Using some of the best transmission electron microscopes available, researchers ... found that so-called “mediator atoms” – carbon atoms that do not fit properly into the graphene lattice – act as catalysts to help bonds break and form. ... "
Mediator atoms help graphene self-heal – Physics World An international team of researchers in Korea, the UK, Japan, the US and France has now cleared up the mystery by showing that fast-moving carbon atoms catalyse many of the restructuring processes.
