Wrapping sponges in graphene nanoribbons allows for Joule heating to help clean up oil spills

(Phys.org)—A team of researchers with the University of Science and Technology of China has found a way to make sponges used to clean up oil spills in the ocean work better when soaking up heavy crude oil. In their paper published in the journal Nature Nanotechnology, the team describes how they wrapped polymeric sponges in graphene nanoribbons and then applied an electric current to cause the sponge to absorb the normally thick oil. Despina Fragouli and Athanassia Athanassiou with Istituto Italiano di Tecnologia in Italy offer a News and Views piece on the work done by the team in the same journal issue.
