Graphene is the modern go-to material for scientists and engineers looking to create all manner of new electronic devices. From ultra-frugal light bulbs (both big and small), to super-efficient solar cells, flexible displays and much more, graphene is a multi-tasking marvel. However, in all of these instances, graphene in its original form of atom-thin, flat sheets has had to be used with peripheral supports and structures because it lacks a solid shape and form of its own. Now researchers from the University of Illinois at Urbana-Champaign have come up with a way of creating 3D objects out of graphene that opens up the possibility of fashioning a whole new range of innovative electronic devices.
