“…The ζ -potential of an ultra-fine particle is often used to evaluate the variety and intensity of charge, and it is a very important index that reflects the repulsive force intensity among particles and the dispersion stability. There exist such functional groups as -COOH, -OH, -NH 2 , and the like on the surface of nanodiamond [6]. The kinds and intensity of functional groups affect its sorption behavior and ionization properties.…”

The effect of Chemical Mechanical Modification (CMM) on the ζ -potential and size distribution of nanodiamonds was studied. Results show significant change in the functional groups on its surface after the CMM treatment by the anionic surface modifier DN-10. The amount of hydroxyl groups decreases and two peaks connected with the stretching vibration of carboxylate appear instead of those of carbonyl. The ζ -potential goes up significantly and the size drops to some extent. If treated further with CMM1, a new absorption peak 1382.19 cm −1 connected with the vibration of some distinctive functional groups which cause the increase in the ζ -potential and the decrease in size appears.

“…It is unlikely that the non-diamond (sp 2 ) carbon is exclusively responsible for these features of the Raman spectra. Additional molecular groups and fragments can also be formed in DCM particles under rapid quenching followed by condensation, as shown in previously published IR spectra of DCM [8][9][10][11]. According to [5], the broad asymmetric Raman band between 1500 and 1700 cm −1 originates from O-H bending vibrations and C=O stretching vibrations.…”

“…Ester groups, which constitute structural units of heterogeneous DCM particles, also complicate the spectra. Their concentration depends on the type of the DCM sample [8][9][10][11].…”

Abstract. Diamond-containing material (DCM) synthesized by detonation was separated into fractions. Raman and infrared spectra and X-ray diffraction patterns of the individual fractions were measured. The particles of this material were characterized by the variable ratio of the diamond (sp 3 ) and non-diamond components. The distribution of sp 3 -grains in the particles was of complicated character. The fine DCM particles contained an insignificant amount of diamond. The influence of density fluctuations on the DCM formation is discussed.

“…2) were characterized by the presence of the main absorption bands near 3600-3000 and 1620 cm -1 (OH groups), 3000-2800 cm -1 (CH x ), 1800-1700 cm -1 (CO), and 1400-700 cm -1 (N, CN, CO, CH groups, etc.). These bands are typical of the surface functional groups of UDD of other types [4,[19][20][21]. The main differences between the spectra of CH-7 and K-2 were the difference in the intensity of the 3000-2800 cm -1 band, the shape of the complex band at 1400-700 cm -1 , and the position and intensity of the 1800-1700 cm -1 band characterizing the configuration of surface C-O bonds (ketone groups, carboxyl anhydrides, and lactones [23]).…”

“…The main reason for this is the substantial influence of the "hard" chemical procedure used to extract MND from meteorites on the chemistry of the surface of particles [14][15][16][17]. A similar dependence of the composition of the functional coating on the surface of nanodiamonds on the procedure for their technological purification is also characteristic of synthetic UDD [18][19][20][21]. With meteorite diamonds, the situation is aggravated by the use of different extraction procedures in different research centers.…”

-The influence of standard chemical treatment used to extract interstellar nanodiamonds from meteorites on the chemical composition of the surface of synthetic nanodiamonds with substantially different properties was studied by thermal desorption mass spectrometry and IR spectroscopy. The chemistry of the surface of nanodiamonds after treatment was substantially different from that of initial particles. The suggestion was made that the chemical structure of the surface of diamond particles in the interstellar space could be reconstructed from the data on meteorite diamonds. Mass spectrometric studies also gave information about possible mechanisms of the release of noble gases from meteorite diamonds at various temperatures.
