Properties of individual fractions of detonation nanodiamond

Nanodiamond aqueous dispersions as potential nanofluids: the determination of properties by thermal lensing and other techniques

“…To use the equation, densities of the base fluid and particles are needed. The latter is determined by a hydrostatic weighing in distilled water [13] or by pycnometry (helium) [14,15]. As for ND powders, manufacturers do not often provide this parameter.…”

Production of Nanodiamond Particles

“…Although, initially, DND modifications were performed on a small scale, currently these steps are being implemented on a large scale on site at DND production centers (Larionova et al, 2006). Postsynthesis processing includes purification of detonation soot from metallic impurities and nondiamond carbon and is typically performed in conjunction with detonation soot synthesis by the same vendor.…”

“…As a means to improve the quality of the DND product, methods of fractionation and deaggregation are discussed below. In fact, suspensions of 5 wt% of 25 nm size DND fraction in water have been produced using the fractionation method (Larionova et al, 2006;Xu et al, 2005a,b,c). The typical commercial polydispersed ND suspensions that are subjected to powerful ultrasound treatments routinely exhibit 200-400 nm average aggregate sizes, which are unbreakable by the ultrasonic treatment.…”

Diamondoid Molecules

“…While diamondoids are structurally well-characterized chemical compounds, NDs are frequently a mixture of several carbonaceous compounds. Their characteristics are governed by many factors, such as starting materials, methods of fabrication and processing (Aleksenskii et al, 1999;Shenderova et al, 2002;Chiganov, 2004;Dolmatov et al, 2004;Larionova et al, 2006;Krueger, 2008a;Nekhaev et al, 2011).
