The Formation and Elasticity of a Hydroxypropyl Cellulose Film at a Water–Air Interface
Colloid Journal - Tập 81 - Trang 696-702 - 2020
A. A. Maklakova, V. G. Kulichikhin, A. Ya. Malkin
The kinetics of spreading of aqueous hydroxypropyl cellulose (HPC) solutions with different concentrations over a water surface and the rheological properties of films formed at the water–air interface have been studied. The performed experiments are distinguished by the fact that the solvent in the polymer solutions is identical to the liquid subphase, while, beginning from a certain concentratio...... hiện toàn bộ
Model Nanoporous Supramolecular Structures Based on Carbon Nanotubes and Hydrocarbons for Methane and Hydrogen Adsorption
Colloid Journal - Tập 80 - Trang 739-750 - 2019
A. V. Shkolin, A. A. Fomkin, V. Yu. Yakovlev, I. E. Men’shchikov
A procedure has been proposed for the self-assembly of carbon nanotubes into arrays with the use of coordinating molecules and the development of secondary porosity in the resulting supramolecular structures. Molecular dynamics has been employed to study the formation of such structures and determine the effective radius of pores formed in them. The average micropore sizes in the obtained supramol...... hiện toàn bộ
Interaction between Globular Proteins and Silica Surfaces
Colloid Journal - - 2002
Yu. I. Tarasevich, L. I. Monakhova
The adsorption of bovine serum albumin on silica of three different types, i.e., aerosil, macroporous silica gel, and ground natural quartz, was studied. The IR spectra of this protein adsorbed on aerosil were measured and analyzed. It was shown that the carbonyl groups of albumin macromolecules interact with vicinal hydroxyl groups while imido groups, with individual hydroxyl groups of silica sur...... hiện toàn bộ

Electrokinetic Characteristics of Porous Glasses in Solutions of Sodium and Iron(III) Chlorides
Colloid Journal - Tập 80 - Trang 255-265 - 2018
L. E. Ermakova, A. V. Volkova, A. S. Kuznetsova, E. A. Grinkevich, T. V. Antropova
The structural (structural resistance coefficient, bulk porosity, average pore radius, and specific surface area) and electrokinetic (surface conductivity and electrokinetic potential) characteristics of high-silica micro- and macroporous glasses produced from two-phase sodium borosilicate glass have been compared in solutions of an indifferent electrolyte (sodium chloride) and iron(III) chloride ...... hiện toàn bộ
Structure and electrophysical properties of self-organized composite layers based on peptide and silver nanoparticles
Colloid Journal - Tập 75 - Trang 301-310 - 2013
A. I. Loskutov, O. Ya. Uryupina, S. N. Grigor’ev, V. B. Oshurko, V. I. Roldughin
Atomic force microscopy, scanning tunnel microscopy, and IR spectroscopy are employed to study composite films formed from dispersions of silver nanoparticles in an aqueous solution of Asp-Glu-Val-Asp-Trp-Phe-Asp peptide on different substrates at room temperature. It is established that pure peptide crystallizes on substrates to yield different structures, the character of which essentially depen...... hiện toàn bộ
Penetration of nanoparticles through screen-type diffusion batteries
Colloid Journal - Tập 72 Số 4 - Trang 491-498 - 2010
V. A. Kirsh, A. A. Kirsh
Functionalization of (CdSe)ZnS nanoparticles in reverse micelles of Aerosol OT
Colloid Journal - Tập 74 Số 4 - Trang 445-455 - 2012
А. Н. Еремин, Г. К. Жавнерко, V. E. Agabekov
Influence of Embedded Protons on the Structure of Ice Microcrystals. Computer Simulation
Colloid Journal - Tập 65 - Trang 248-256 - 2003
S. V. Shevkunov
Ice microcrystals of 40 molecules with embedded proton and placed in the external electric field were simulated by the Monte Carlo method in connection with the problem of the destruction of the ozone layer in the stratosphere. The proton field does not disturb the cluster crystalline state, whereas the electric field of crystal defects on the ice surface can affect essentially the microcrystal me...... hiện toàn bộ
Structure of silver clusters with magic numbers of atoms by data of molecular dynamics
Colloid Journal - Tập 70 - Trang 284-296 - 2008
V. I. Kuzmin, D. L. Tytik, D. K. Belashchenko, A. N. Sirenko
The behavior of silver clusters (cubic octahedron habit) with magic numbers of atoms N = 13, 55, 146, 309, 561, 923, 1415, and 2057 in the 0–1300 K temperature range is studied for the embeded atom model by the molecular dynamics method. The structural method for the analysis of the dynamics of local configurations of atoms based on the construction of angular characteristics of simplexes of the D...... hiện toàn bộ
