Modification and comparative study of commercial nanodiamonds / A. P. Puzyr, A. E. Burov, V. S. Bondar // Fullerenes Nanotubes Carbon Nanostruct. - 2015. - Vol. 23, Is. 2. - P93-97, DOI 10.1080/1536383X.2013.794338 . - ISSN 1536-383X

Аннотация: Detonation nanodiamond powders produced by different manufacturers were surface modified to reduce the amount of surface impurities and impart to the particles a high colloidal stability in aqueous suspensions. Modified DNDs (MDNDs) were separated into fractions and evaluated by the zeta potential, particles size distribution and elemental composition. MDNDs retain colloidal stability after the hydrosols are dried and the resulting powders are resuspended. Sedimentation stability and fraction composition are proposed as parameters for standardization of commercial nanodiamonds. © 2015 Copyright © Taylor & Francis Group, LLC.

Аннотация: The addition of metallic Ir and Pt to a fullerene-forming, atmospheric-pressure plasma reactor was found to influence the generation of carbonaceous products. It was observed that the added metals were efficiently dispersed into the plasma and that their presence increased the yield of fullerenes. The addition of Ir led to a noticeable shift in the fullerene distribution towards C-60, whereas the addition of Pt increased the proportion Of C-60 oxides and decreased the proportion of higher fullerenes. Addition of Ir also caused a reduction of the soot particle size and the formation of a considerable quantity of carbon nanotubes.

Dissolution and mixing of flavin mononucleotide in microfluidic chips for bioassay / K. I. Belousov [et al.] // J. Phys. Conf. Ser. - 2016. - Vol. 741, Is. 1, DOI 10.1088/1742-6596/741/1/012058 . - ISSN 1742-6588

Аннотация: Dissolution and mixing of flavin mononucleotide (FMN), which activates a luminescent reaction, were considered in various designs of microfluidic chip for pollution analysis of liquid samples. The aim was to determine the velocity mode of fluid flow ensured the uniform distribution of the FMN in the reaction chamber. Simulation of concentration distribution of FMN in various designs of microfluidic chips was conducted. It was shown that the passive mixing techniques based on the constant flow rate didn't provide mixing of FMN in acceptable time (3 seconds). The most efficient mixing was achieved using variable flow rate with a gradually increasing frequency of oscillation. © Published under licence by IOP Publishing Ltd.
