About the cover

May 2017 Volume 12 No 5

Crude oil spills represent a major source of marine and coastal pollution. A promising way to clean up spills is the use of sponges that can selectively absorb oil and not water. This can be achieved for example by coating the surface of polymer foams with nanostructures that render the foams more hydrophobic and more oleophilic simultaneously. Shu-Hong Yu and co-workers have now shown the right choice of coating nanomaterial can provide additional advantages. They have coated polymer foams with graphene nanostructures and shown that applying an electric voltage to the graphene produced enough local heating to reduce the oil viscosity and increase the absorption speed substantially. The conceptual image on the cover illustrates the idea of using graphene to aid oil spill remediation.
