Carbon is a non-metal element that can form three different giant covalent structures: diamond, graphite and graphene. A carbon atom can form up to four covalent bonds. Diamond, ...

Here Lu et al.develop an automated surface structure-searching method, and when applied on studying surface reconstruction of a diamond surface, self-assembled carbon nanotubes are found.

Millimetre-sized single crystals of covalent organic frameworks have been constructed by taking advantage of a reversible dimerization reaction of nitroso groups.
