Imagine how limiting it would be if steel, wood or plastic only existed in the form of thin sheets. Well, that’s been the case so far when it comes to graphene. While its incredible strength and high conductivity make it very useful in things like semiconductors, batteries and solar cells, there’s no doubt that it would be even more useful if it could be produced in three-dimensional blocks. Scientists at Australia’s Monash University have now managed to do just that – by copying the structure of cork.
