The milling method provides a homogeneous population of ultrasmall quasi-spherical diamond nanoparticles TEM/HRTEM images from fP (a) and fND (b)–(d) as defined in figure 1. (e) HRTEM image of typical nanodiamond (f) FFT analysis of the nanodiamond crystalline structure where the c-diamond d 111 spacing is given by the inverse of the ring radius. The distance between the {111} planes is equal to a sin θ ≈ 2.06 Å, where a = 3.5625 Å is the unit cell dimension and θ = 0.6154 rad is the angle between the {111} and the {110} planes.
