Rutgers University: Researchers in the Materials Science and Engineering Department at Rutgers University report a method for creating uniform films of reduced graphene oxide over large areas. 

As stated in their April 6 publication in Nature Nanotechnology: "We describe a simple and reproducible method to uniformly deposit between one and five layers of graphene from reduced GO in the form of thin films to create transistors and proof-of-concept electrodes for organic photovoltaics."
