(Source: Purdue University) November 9, 2015 New research shows wrapping silver nanowires, which are promising for applications such as flexible displays and solar cells, with an ultrathin layer of carbon called graphene protects the structures from damage and could represent a key to realizing their commercial potential. The lower images depict how graphene sheathing protects the nanowires even while being subjected to 2.5 megawatts of energy intensity per square centimeter from a high-energy laser, an intensity that vaporizes the unwrapped wires. The upper images depict how the unwrapped wires are damaged with an energy intensity as little as .8 megawatts per square centimeter. (Purdue...
