ON THE COVER:
Asteroidea Electrica,
first place winner of the 2014 Department of Engineering photo competition
at The University of Cambridge, UK, sponsored by ZEISS. The image is a false colored, low magnification electron
micrograph of freestanding graphene foam. Electrically conductive, highly porous, and lightweight, the foam could
be used in applications such as energy storage and ultra-lightweight structures. Courtesy of Indrat Aria.
