“…As shown above, several authors [8][9][10][11] reported on coexistence of cubic and hexagonal diamond phases in diamond samples prepared by HPHT and shock wave compression methods, while Nemeth et al reported on defective cubic phase in a meteoritic diamond [13]. Taking into account this diversity of the results and interpretations, we analyze our XRD data within the frameworks of both above-mentioned models, in order to realize which of them better suits our experimental data.…”

“…This phenomenon is often observed in the diamonds prepared by HPHT and shock wave compression methods [8][9][10][11]. Herewith, some authors [8,9,11] reported that the diamond products fabricated by the shock wave synthesis involve both cubic (3C) diamond (space group Fd3m, the lattice constant a ¼ 3.567 Å, Z ¼ 8, C-C bond length 1.544 Å) and hexagonal diamond phases, particularly Lonsdaleite 2H (space group P6 3 /mmc, a ¼ 2.52 A, c ¼ 4.12 A, Z ¼ 4) and 6H polytypes.…”

Phone: þ 7 812 904 5298, Fax: þ 7 812 297 1017We report on XRD, NMR, and EPR study of commercial micro-and nano-diamonds of the SSX series fabricated by a shock wave compression method. XRD data analysis shows that SSX samples consist of nanometer cubic diamond domains intermixing with stacking faults and twins. We show that as-received samples reveal a graphitic component, which may be removed by additional purification. Crushing the initial microdiamond powder into submicron and nanometer sizes does not result in noticeable variations of the XRD, NMR, and EPR parameters. This finding is explained by the fact that SSX diamonds are polycrystalline aggregates consisting of numerous nanocrystallites of $20-25 nm in size. Therefore, soft crushing of these aggregates diminishes their size, but leaves constituting nanocrystallites and their intrinsically facet surfaces mainly untreated. With that some modification of the outer nanocrystallite surface on crushing is observed.

“…Recent work shows this technique permits to confirm the tetrahedral insertion of boron atoms in diamond leading to p-doping [61,62]. EELS combined with scanning TEM (STEM) can even provide mapping or profiles of impurities with an atomic resolution [63][64][65]. Near-edge X-ray absorption fine structure (NEXAFS) technique could probe the local bonding environment [66].…”

“…Formation of an organized molecular film of organo-modified nanodiamond was also confirmed by Laser Raman spectroscopy. A diamond-specific 1330 cm -1 Raman shift band 10 was confirmed in the Raman spectrum of the organized film, in addition to the C-C band at 1098 cm -1 . In a nutshell, it was not possible to obtain a quite homogeneous single particle film at this stage.…”

The Role of Modifying Molecular Chains in the Formation of Organized Molecular Films of Organo-modified Inorganic Particles

2017

The role of organo-modifying molecular chains in the formation of molecular films of organo-modified nanodiamond is discussed herein based on interfacial chemical particleintegration of organo-modified nanodiamond having a particle size of 5 nm. The surface of nanodiamond is known to be covered with a nano-layer of adsorbed water. This water nano-layer was exploited for organo-modification of nanodiamond with long-chain fatty acids via adsorption, leading to nano-dispersion of nanodiamond in general organic solvents as a mimic of solvency. The organo-modified nanodiamond dispersed "solution" was used as a spreading solution for depositing a mono-"particle" layer on the water surface, and a Langmuir particle layer was integrated at the air/water interface. Multi-"particle" layers were then formed via the Langmuir-Blodgett technique, and were subjected to fine structural analysis. The effect of organo-modification enabled integration and multilayer formation of inorganic nano-particles due to enhancement of the van der Waals interactions between the chains. That is to say, the "encounter" between the organo-modifying chain and the inorganic particles led to solubilization of the inorganic particles and enhanced interactions between the particles, which can be regarded as imparting new function to the organic molecules.
