✦ Synopsis

Evidence for the formation of an archetypal hemi-toroidal link structure between adjacent concentric walls in pyrolytic carbon nanotubes is presented. The observed and simulated TEM images for such structures are in excellent agreement.

This study suggests that double-walled carbon nanotubes, in which the inner and outer tubes are linked by such hemi-toroidal seals, may be one viable way of overcoming the reactivity at the graphene edges of open-ended tubes to engineer stable and useful graphene nanostructures.
