Graphene 'Invisible' to Water (1 of 2) (IMAGE) Rensselaer Polytechnic Institute Caption Graphene is the thinnest material known to science. The nanomaterial is so thin, in fact, water often doesn’t even know it's there. A new study from Rensselaer Polytechnic Institute shows how the extreme thinness of graphene enables near-perfect wetting transparency. The findings could help inform a new generation of graphene-based flexible electronic devices. Additionally, the research suggests a new type of heat pipe that uses graphene-coated copper to cool computer chips.
