Microcrystallites and Granularity of Detonation Nanodiamonds

2020 21st International Conference of Young Specialists on Micro/Nanotechnologies and Electron Devices (EDM), 2020
At the present moment6 science and technology use detonation synthesis nanodiamonds, obtained both from the carbon of an explosive molecule and from a mixture of explosive with the addition of graphite or soot. In the latter case, the diamonds are larger.

Zwitterion-Functionalized Detonation Nanodiamond with Superior Protein Repulsion and Colloidal Stability in Physiological Media.

Small, 2019
Nanodiamond (ND) is a versatile and promising material for bioapplications. Despite many efforts, agglomeration of nanodiamond and the nonspecific adsorption of proteins on the ND surface when exposed to biofluids remains a major obstacle for biomedical ...

Surface characterization of detonation nanodiamond particles

Russian Journal of General Chemistry, 2012
Specific features of formation of stable suspensions of detonation nanodiamond (DND) in media of different polarities were considered. A relation between the dispersity of DND particles and their surface activity was found. The surface activity of diamond nanoparticles (10–100 nm) is significantly (by a factor of 4) lower than that of submicron-sized ...

Inroad to modification of detonation nanodiamond

Diamond and Related Materials, 2006
Abstract Our research is directed towards finding inroad(s) for conversion of detonation nanodiamond to more standard nanopowder with, first of all, enhancement of chemical and phase purity and, secondly, establish monofunctional surface termination.
