Graphene Nanoribbon-Based Film (IMAGE) Rice University Caption Test samples show a graphene nanoribbon-based film developed at Rice University with both passive and active de-icing properties. When the film at left is heated without an application of lubricants, ice melts but water droplets remain on the surface. With lubricants, at right, ice begins to melt and slides off. The material may be suitable for de-icing and anti-icing applications in extreme environments. Credit Tour Group/Rice University Usage Restrictions For news reporting purposes only.
