The Thermal Stability of Nanodiamond Surface Groups and Onset of Nanodiamond Graphitization

Surface Modifications of Nanodiamonds and Current Issues for Their Biomedical Applications

“…Surface of NDs could be saturated with carboxyl functions using nitric (HNO 3 ), sulfuric (H 2 SO 4 ) or perchloric (HCl) acids. A mixture of these acids in equal amounts reveals powerful [ 45,89,123]. "Piranha" water (sulfuric acid and hydrogen peroxide) constitutes an efficient alternative [124].…”

Understanding structure and porosity of nanodiamond-derived carbon onions

“…Transmission electron microscopy (TEM) investigations have shown that smaller particles can be transformed to sp 2 -hybridized carbon more readily resulting in a possible coexistence of small carbon onions with larger, partially transformed nanodiamonds [15,37,38]. In addition, the presence of surface functional groups significantly influences the onset temperature of the nanodiamond-to-OLC conversion [38].…”

Vacuum or flowing argon: What is the best synthesis atmosphere for nanodiamond-derived carbon onions for supercapacitor electrodes?

“…Thus, functional groups decompose which initially had stabilized the ND surface. The thermal stability of ND surface functional groups has been investigated in several studies [7,[34][35][36][37].
