Graphene nanoribbons can be
transformed into carbon nanotubes

The basic idea is simple and easily explained: just twist the ends of a strap on your backpack and watch what happens. Being classical in origin, the mechanism is robust and valid on the macro-, micro- and nanoscale.
The mechanism also enables experimental control, which has earlier been impossible. The mechanism can be used to make various kinds of novel carbon nanotubes, to encapsulate molecules insides the tubes, or to make tubules from ribbons made out of other planar nanomaterials.
For the past twenty years, carbon nanotubes have been described as “rolled-up graphenes”, even though no-one ever really did the rolling. Today, nanotubes, along with many other nanomaterials, are made by atom-by-atom growth.
The research used the computer resources of the Finnish IT Centre for Science (CSC), based in Espoo and has received funding from the Academy of Finland.
