An annual photo competition held by faculty of engineering at the University of Cambridge aims to present the wide variety of engineering research at the university. This year, the winner of this competition was an incredible electron micrograph photo of free-standing graphene foam.

The graphene foam was made by growing a few layers of graphene on the surface of a porous metal foam skeleton (by CVD), then removing it by dissolving it in etching solution. The photo, by Adrianus Indrat Aria, was called Asteroidea Electrica.
