Nanotubes and Graphene Sheets (IMAGE) Rice University Caption Researchers at Rice University and Montreal Polytechnic analyzed the electromagnetic effects of junctions between nanotubes and graphene sheets. From top to bottom are a graphene/carbon nanotube hybrid with seven-membered junctions, a graphene/carbon nanotube hybrid with eight-membered junctions and a graphene/BNNT hybrid with eight-membered junctions.
