Graphene: Calling all chemists
Abstract
Graphene has potentially useful electronic properties but it is difficult to produce and process on large scales. Working with chemically modified forms of graphene |[mdash]| such as graphene oxide |[mdash]| may provide an alternative. There has been an explosion of interest in the physics of graphene — individual layers of graphite in which each carbon atom is bonded to three other carbon atoms — since it was first deposited by mechanical exfoliation in 2004. In this approach, which has spawned a cottage industry of 'peeling and rubbing' in labs around the world, the large majority of platelets are actually too thick to be of use in fundamental physics experiments, so well-trained eyes are needed to find the relatively few monolayer flakes that are produced.
