Graphene Nanoscrolls

Caption: After decoration with maghemite nanoparticles the graphene spontaneously form nanoscrolls. The dark cylinders in the upper part of the image shows graphene nanoscrolls that are covered with a smooth layer of small particles. The nanoscrolls form "bundles" with 5-10 cylinders due to the interaction between the nanoscrolls. The lower part of the image show a simulated image of a graphene sheet in the scrolling process. The region zoomed show a maghemite nanoparticle attached to the graphene sheet.
