Graphene oxide (GO) is an organic macromolecule that is only a couple of atoms thick but thousands of atoms wide (like a molecular-scale bed sheet). Koltonow and his colleagues are able to assemble these atomically-thin sheets into a solid, conductive foam with a high surface area. The foam can be used to create electrodes for batteries and supercapacitors, making such energy storage devices smaller and lighter. In this image, GO sheets (purple-orange) cast shadows from light that is scattered off the foam (green-yellow), creating an eerie effect.
