Nanodiamonds (NDs) represent an elegant carbon allotrope that bears some of the glint of the precious gemstone at the nanoscale level (<10 nm) [1, 2, 3]. Besides esthetics, NDs additionally display a set of unique structural, physical, and chemical properties that have drawn the attention of materials' scientists and engineers [4, 5, 6, 7, 8, 9, 10, 11]. Though covered in a veil of secrecy for decades, the large-scale commercialization of synthetic nanopowders at reasonable prices has now made this material widely available for research and development, triggering a rapid expansion of the field. High-grade ND powders available in the market today are prepared using the detonation method, i.e., detonation NDs . The prime nanoparticles in these powders are spherical, crystalline, and monodisperse with an average size of ca. 4–5 nm. Moreover, they appear sintered to each other forming coarse, yet tight agglutinates [13, 14]. The agglutinates are few nanoparticles thick and several...
