Researchers from the US Department of Energy's Oak Ridge National Laboratory that graphene grains shape and size are controlled by hydrogen and not only by carbon. The team developed a method to grow graphene grains that has perfect hexagonal shapes.
Up until now hyrogen was thought to play a passive role in the process of making graphene - but the new research shows that it has a crucial role.
