A June 23, 2016 news item on Nanowerk makes the announcement,
The National Nanotechnology Coordination Office (NNCO) is pleased to announce the winners of the latest round of EnvisioNano, a nanotechnology image contest for students. Ben Davis and Ryan Hines, members of the Maschmann Lab at the University of Missouri, won for their image Graphene Shows its Stripes. They work on innovative methods to machine nanomaterials like graphene in order to capitalize on the transformative properties of these materials. Congratulations to Ben and Ryan!
A June 23, 2016 US National Nanotechnology Initiative (NNI) news release, which originated the news item, provides more detail about the voting,
Images posted online for public voting received more than 2,000 votes. The top three images advanced to the semifinalist round. The final winner was chosen by representatives of the National Nanotechnology Initiative (NNI) member agencies. The winning image will be displayed on Nano.gov for a month. For more information on the EnvisioNano contest rules and judging, visit the EnvisioNano page.
The news release goes on to reveal more about the contest-winning image,
Graphene Shows its Stripes: “This image shows a grain of graphene which was synthesized using chemical vapor deposition on a copper foil substrate. The hexagonal shape of the graphene grain is indicative of the graphene hexagonal crystal lattice structure, while the striped pattern arises due to adhesion and wrinkling with the underlying substrate. Graphene is a 2-D material with mechanical, electrical, and thermal properties that exceed conventional engineering materials.”
