ABSTRACT
Diamonds possess a unique combination of high chemical resistance, highest hardness and wear resistance, low thermal expansion coefficient, highest heat conductivity, and wide energy gap. The key distinctive feature of detonation nanodiamonds (DNDs) from other diamonds originates from the ability to have on their surface a large amount of oxygen-containing functional groups predetermining the hydrophilcity of DNDs on graphene layers lying on a diamond core. Only the manufacture of DNDs in large-tonnage amounts can be mastered in a short time, which sets them apart from other highly active forms of carbon.
