ABSTRACT
Detonation nanodiamonds (DNDs) are attracting presently consid-
erable interest as an affordable starting material for production
of carbon onion, nanographite, and graphene nanoparticles. As
mentioned in Chapter 1, transformation of DND particles into
carbon onions and nanographite can be readily achieved by high-
temperature annealing. The first thorough investigation of this
phase transition, DND-carbon onion-nanographite, can be traced to
Refs. [1, 2]. A comprehensive study of the mechanism and intrinsic
details of the nanodiamond-nanographite structural transformation
[3-5] established the possibility of investigating the optical [6, 7]
and magnetic [8, 9] effects in the onion-like and nanographite
forms of carbon, which derive from the well-developed π electronic
system.
