The Properties of 3 nm-Sized Detonation Diamond from the Point of View of Colloid Science

The colloidal properties of the hydrosol of a detonation nanodiamond have been considered and discussed. The 3nm-sized positively charged colloidal species produced by the NanoCarbon Research Institute, Japan, undergo a further aggregation on the dilution. They exhibit the emission at 625 nm with the excitation maximum at 491 nm, adsorb anionic dyes, and readily coagulate at the adding of electrolytes. The coagulation occurs in line with the...
