Graphene nanoribbons

Twisted within nanotubes

Single-walled carbon nanotubes have been used as test tubes for chemical reactions in an electron microscope. It is now shown that they can also act as reactors for the synthesis of narrow, helically twisted graphene nanoribbons through electron irradiation of functionalized fullerenes.
