First switchable graphene nanoribbon that twists on demand

Researchers at Nagoya University have built a graphene nanoribbon that can switch the direction of its twist using a natural solvent. Graphene nanoribbons are thin, ribbon-shaped structures made of fused carbon rings. Twisted or helical versions of these ribbons show promise for advanced light and electronic devices. However, until now, no graphene nanoribbon could switch its twist on demand.
