Experimental Study of Transport Coefficients of Aqueous Suspensions of Nanodiamonds
Colloid Journal - Tập 82 - Trang 705-712 - 2020
M. I. Pryazhnikov, A. V. Minakov, A. I. Lyamkin, V. E. Red’kin, S. M. Zharkov, G. M. Zeer
This article presents experimental data on the coefficients of viscosity and thermal and electrical conductivities, as well as the absorption spectra, of suspensions of ultradispersed diamonds. Suspensions of UDA-S and UDP-A detonation nanodiamond particles, as well as UDP-AG diamond–graphite powder, are used in the experiments. The concentration of nanodiamonds in distilled water is varied within...... hiện toàn bộ
The adsorption properties of aluminophosphates prepared by the template method from deanionized alumina sol
Colloid Journal - Tập 68 - Trang 194-200 - 2006
T. F. Kuznetsova, A. I. Rat’ko, O. A. Kudina
Isotherms of adsorption-desorption of tetrachloromethane vapors by mesoporous aluminophosphate precipitated with the cetylpyridinium template from an alumina sol deanionized by ion-exchange are measured. As the concentration of the cetylpyridinium template varies from 0.045 to 1.8 wt %, the aluminophosphate samples are shown to have a bi-or unimodal distribution of the volume of mesopores with res...... hiện toàn bộ
Elastic properties of a nematic in a tetrapalladium organyl-pentadecane system
Colloid Journal - Tập 70 - Trang 268-273 - 2008
A. V. Golovanov, G. V. Ryabchuk
The temperature dependences of birefringence Δn, anisotropy of permittivity ɛa, and elastic constants K 11 and K 33 in the nematic phase of a tetrapalladium organyl-pentadecane system with a pentadecane content of 55 wt % have been investigated experimentally. It has been shown that, as temperature is elevated, ɛa, K 11, and K...... hiện toàn bộ
Effect of alkylpyridinium chlorides on aggregation stability of aqueous dispersions of detonation nanodiamonds
Colloid Journal - Tập 79 - Trang 126-132 - 2017
O. A. Soboleva, G. A. Khamenov, V. Yu. Dolmatov, V. G. Sergeyev
Adsorption of decyl-, dodecyl-, and hexadecylpyridinium chlorides (DePC, DoPC, and CPC, respectively) from aqueous solutions on the surface of detonation nanodiamonds (NDs) and its effect on the aggregation stability of ND hydrosols are studied. Hydrophobic interactions, which are enhanced with the length of hydrocarbon chains in surfactant molecules, are found to play the main role in surfactant ...... hiện toàn bộ
Synthesis and Electrosurface Properties of One- and Two-Component Nanostructures
Colloid Journal - Tập 67 Số 4 - Trang 422-426 - 2005
N. F. Bogdanova, Л. Э. Ермакова, P. S. Chikhachev, М. П. Сидорова, Dmitry Aleksandrov, I. A. Savina
Kinetics of lecithin oxidation in liposomal aqueous solutions
Colloid Journal - Tập 73 - Trang 815-821 - 2011
E. A. Mengele, I. G. Plashchina, O. T. Kasaikina
The peculiarities of egg phosphatidylcholine (lecithin) oxidation with molecular oxygen in aqueous media are investigated. Under the action of ultrasound, lecithin forms multilamellar liposomes or vesicles in aqueous solutions. Lecithin is oxidized through a chain free-radical mechanism. The nonlinear dependence of the rate of oxygen absorption on the substrate concentration and the imitation of t...... hiện toàn bộ
Formation of submicrometer-scale gold nanoparticle aggregates and their self-organization into “supracrystals”
Colloid Journal - Tập 69 - Trang 391-393 - 2007
Yonglan Luo
Nearly spherical, submicrometer-scale gold nanoparticle aggregates about 250 nm in diameter are formed directly from an HAuCl4-p-phenylenediamine aqueous solution at room temperature. The as-formed aggregates were characterized by various techniques, including scanning electron microscopy, transmission electron microscopy, and X-ray diffraction, and their formation mechanism is discussed. It is ve...... hiện toàn bộ
Electrosurface Properties of Hydr(oxides) and Oxide Nanostructures in 1 : 1 Electrolyte Solutions: 2. Electrokinetic Characteristics of Boehmite, Goethite, and Silicon Dioxide
Colloid Journal - Tập 63 - Trang 568-572 - 2001
A. V. Klebanov, N. F. Bogdanova, L. E. Ermakova, M. P. Sidorova
The electrophoretic mobility of particles of silicon dioxide, aluminum hydroxide, and iron hydroxide was measured as a function of pH in NaCl and KCl background solutions. Isoelectric points for the investigated objects were determined. Electrokinetic potentials were calculated with allowances for the particle shape and the polarization of the electrical double layer within the framework of the Ov...... hiện toàn bộ
Evolution of extinction spectra of monolayer plasmon-resonant colloidal crystals in the process of their synthesis by the moving meniscus method
Colloid Journal - Tập 73 - Trang 801-806 - 2011
S. V. Karpov, A. E. Ershov, A. P. Gavrilyuk
Regularities of the evolution of the extinction spectra of periodic colloidal structure composed of silver nanoparticles formed from bulk hydrosol on the surface of dielectric substrate are studied using the moving meniscus method. Spectra were calculated by the coupled dipole method. The effect of individual parameters of disperse system on the pattern of extinction contour in the band of plasmon...... hiện toàn bộ
Asymptotics of distribution functions in wedge-shaped film
Colloid Journal - Tập 72 - Trang 301-306 - 2010
E. N. Brodskaya, F. M. Kunib, A. I. Rusanov
Asymptotic formulas are derived for one- and two-particle distribution functions in a liquid wedge-shaped film. These formulas are valid at fairly large distances from the solid walls that confine the film. Along with the dependence on distances to solid walls, these formulas also determine the dependence on the opening angle of the wedge-shaped pore. In the limit of a straight angle, formulas are...... hiện toàn bộ
