Investigation of the Adsorption Properties of a Nanodiamond Surface after Liquid-Phase Oxidation
In this work, the hydrophilicity of a nanodiamond (ND) with an additionally oxidized surface was studied by reversed gas chromatography. Specific retention volumes V and differential-molar isosteric heats of adsorption of water and heptane q st were measured. It is established that values V of water...
