The influence of solution pH on H+-Cu2+ exchange equilibrium was studied for the disperse copper- KU-23 (15/100 S) macroporous strongly acid sulfocation exchanger
nanocomposite. In dilute solutions of copper(II) sulfate in weakly acid media (pH 3–6), ion exchange limitation is related
to the consumption of hydrogen counterions and the formation of copper counterions in a side reaction between copper particles
and impurity oxygen. The concentration of hydrogen counterions in the nanocomposite is replenished as pH decreases because
of their sorption from solution together with copper ions.

We demonstrated the possibility of preparing continuous silver shells on particles of polystyrene latex by enlarging adsorbed
seeding metal nanoparticles in solution containing ascorbic acid and silver nitrate. It is shown that a strong batochromic
shift of the maximum of surface plasmon resonance is observed for such composite structures.

Transformations of the specific surface area and porous structure of carbon materials based on graphite were studied by low-temperature
adsorption of nitrogen. Exfoliated graphite and graphite foil were found to have a developed (compared with the initial graphite)
surface (up to 90 m2/g) and a porous structure formed by slit-like mesopores with a characteristic radius of ∼20 ?. The determining influence
of the method of synthesis on the adsorption properties of materials was demonstrated for the first time.

The dependence of electrical conductivity on the concentration of CdS (c) and temperature (T) over the temperature range 10–300 K was studied for poly-p-xylylene-CdS (PPX + CdS) nanocomposites prepared by solid-state cryochemical synthesis. The results were discussed in terms
of the heterogeneous conductivity model including various charge transfer mechanisms in various nanocomposite regions. Under
the illumination of a film with c > 11 vol % by a daylight lamp, the conductivity increased, and the σ(T) dependence was metallic in character at low temperatures. The photoconductivity of films at larger concentrations c was caused by the appearance of photoexcited electrons in CdS nanoparticles, the separation of charges at the nanoparticle-matrix
boundary, and percolation effects in films. The PPX matrix was shown to actively participate in electrical conductivity; electrons
in this matrix jumped between phenyl rings. The experimental dependence of dark conductivity σ(T) at temperatures from 150 to 300 K was analyzed using the Mott hopping conductivity model with variable jump lengths. The
main points of the Mott theory of hopping conductivity were discussed.

The impregnation of thermoplastic polymers (polyethylene, polypropylene, polymethyl methacrylate, and polycarbonate) with
photochromic compounds from the class of indoline spirooxazines in supercritical carbon dioxide (SC-CO2) was studied. The concentration of the photochrome and the kinetics of decolorization of its colored form depended strongly
on the type of the polymer matrix and the structure of spirooxazine. The introduction of 1,3′,3′-trimethylspiro(indoline-2′,3-3H-anthraceno[2,1-b][1,4]oxazine)
(SAO) into polycarbonate caused anomalous stabilization (the prolonged conservation of the excited colored form of SAO in
the polymer matrix). In contrast to other photochrome-polymer pairs, after supercritical impregnation into polycarbonate,
at least 10% of all SAO molecules were in the colored form, which was highly stable and did not decolorize after 150 days;
the rest of the impregnated SAO molecules were localized in the matrix as individual molecules, partially colorized after
matrix relaxation, or nanocrystals of characteristic sizes ∼10–20 nm. The mechanisms of the anomalous stabilization of the
colored SAO form in the polycarbonate matrix are discussed.

Micro-mesoporous materials with various ratios between micro- and mesopores were prepared by the recrystallization of zeolite
BEA in an alkaline medium in the presence of cetyltrimethylammonium bromide. The materials were characterized by X-ray diffraction,
low-temperature nitrogen adsorption, and IR spectroscopy. Recrystallization under mild conditions did not cause substantial
changes in the number of acid centers but increased the accessibility of acid centers to large-sized molecules because of
the creation of mesopores. An increase in the degree of recrystallization caused first partial and then complete zeolite transformation
into MSM-41 mesoporous aluminosilicate, which was accompanied by a decrease in the number of acid centers. The IR spectra
were used to determine the diffusion coefficients of cumene in the initial and recrystallized samples. Recrystallization increased
the diffusion coefficient by 3–4 times.

Abstarct The reaction of nickel with benzyl bromide in DMF has been studied. The reaction intermediates were investigated by different
methods and the kinetic and thermodynamic parameters were determined. The reaction of benzyl bromide with nickel was shown
to occur on the metal surface by the Langmuir-Hinshelwood scheme, with the formation of benzyl radicals which are recombined
and isomerized in solution to form 1,2-diphenylethane and trace amounts of 4.4′-dimethylbiphenyl.

The influence of EDTA and OEDP on the magnetite dissolution rate in various experimental conditions was studied. From a comparative
analysis of rate data in commensurate conditions, EDTA is a more efficient complexone than OEDP. The effect of both the nitrogen-bearing
and the phosphorus-bearing complexones was to change the potential at the oxide/solution interface. The potential-controlling
reaction was recognized as FeIIIY− + H+ + e = FeIIHY−.

The behavior of an immobile granular sorbent bed in one-component sorption in a column reactor is described in terms of the
kinetic model of redox sorption taking into consideration the dispersity of metal particles, their radial distribution, peculiarities
of chemical oxidation, and the relation of the overall rate of the process to the properties of the ion exchange matrix. The
mathematical problem is formulated and solved numerically; the solution is analyzed theoretically in relation to the basic
parameters of the sorption system. A satisfactory agreement is obtained between the experimental and calculated data on the
reductive sorption of molecular oxygen from water on a copper-containing electron-ion exchanger.

The optical absorption spectra of molybdenum disulfide prepared by monolayer dispersion of a crystalline precursor in a liquid
medium were studied. On the whole, the three-dimensional structure of the crystalline analogue was reconstructed in disperse
MoS2 dried to a powder state. A substantial fraction of the material transformed into a nanosized state during dispersion and
was stabilized in the form of nanoparticles in various solvents. The stabilizing action of the solvents studied decreased
in the series acetonitrile, ethanol > chloroform > water. The data on the optical absorption of MoS2 suspensions in various solvents were evidence of a broad particle-size distribution. Along with nanoscale particles, the
samples contained larger particles responsible for long-wave absorption (>600 nm). The size of nanoparticles was estimated
using an empirical correlation between the position of maximum A (the long-wave maximum of the first allowed absorption band) in the absorption spectrum and the size of particles (2R). This correlation was obtained using the literature data on monodisperse particles and mixtures of particles. The number
of particles showed a tendency to increase as the concentration of disperse MoS2 in acetonitrile decreased.

The state of the components in the aromatic polyamide-water system was studied by NMR and sorption. A comparative analysis
of spin-lattice and spin-spin relaxation in aromatic para-polyamide (para-aramid) technical fibers Rusar, Kevlar, and Technora was performed depending on the sorption value. The NMR results correlated
with the supramolecular structure of polymers and quasi-chemical equation parameters for water vapor sorption.

2-(1-Trifluoromethanesulfonylamido-2,2,2-trichloroethyl)pyrrole and 2,5-bis(1-trifluoromethanesulfonylamido-2,2,2-trichloroethyl)pyrrole
according to quantum chemical calculations (B3LYP/6-311G**) exist in the isomeric forms whose structure determines the formation
of intramolecular hydrogen bonds NH⋯Cl, NH⋯O=S and CH⋯O=S of different strength. Potentiometric and spectroscopic acidity
of these compounds is determined. From the data of IR spectroscopy their proton donating ability upon interaction with Lewis
bases is shown depending on the presence of intramolecular hydrogen bonds, mutual effects of intermolecular hydrogen bonds
formed by the sulfonamide and pyrrole NH groups with the base, and electronic effects of the substituents.

The Glukauf chromatography method was used to study the adsorption of benzene on a microporous carbon material prepared by
the pyrolysis of hypercrosslinked polystyrene. The thermodynamic characteristics of adsorption were determined as functions
of the degree of pore filling. Over the range of relative pressures studied (<0.005), adsorption was shown to occur in ultramicropores
by the mechanism of primary filling without condensed phase formation.

A series of zinc and aluminum phthalocyanines containing 3–8 pyridiniomethyl or cholinyl substituents on average were synthesized.
As the number of cation substituents increased, in aqueous solutions, the aggregation ability of phthalocyanines decreased,
while the quantum yields of fluorescence and singlet oxygen generation increased. The photodynamic inactivation of coliform
bacteria sensitized by zinc and aluminum phthalocyanine polycations with an increase in the substitution degree became more
effective.

The influence of carrier gas pressure on the retention factor k′ of light hydrocarbons C1–C4 in a monolithic capillary column based on divinylbenzene was studied. It was shown that, for monolithic columns and nonideal
carrier gases, the pressure dependence of lnk′ was nonlinear over a wide pressure range and could be described by the classic Everett equation. It was concluded that the
competitive adsorption model failed to describe the experimental data correctly, especially for strongly retained sorbates
and/or heavy carrier gases.
