Doctoral candidate Shouen Zhu is making millimetres of high-quality graphene for a fraction of the current price. Meet the man who would like to bring graphene out of the lab and onto the street. Until now, the most common method of producing the single-layered carbon has involved an endless process of peeling off pencil marks. Before any of the grandiose promises associated with this material can be realised, it will need to be quite a bit less expensive. ‘A small piece currently costs €1000. In a few years, I think the price can be around €1’.
