Ivanovo State University of Chemistry and Technology or ISUCT is a research facility and a university located in Ivanovo, the administrative center of Ivanovo Oblast, Russia.It was founded in 1918 as Chemical Faculty of Ivanovo-Vosnesensk Polytechnic Institute. In 1930, Ivanovo-Vosnessensk Polytechnic Institute was split into four independent schools: Ivanovo Textile Institute, Ivanovo Power Institute, Civil Engineering Institute, and Ivanovo Institute of Chemistry and Technology . The latter gained a new status in 1992 and was renamed to Ivanovo State Academy of Chemistry and Technology, and in 1998 it was renamed again, becoming Ivanovo State University of Chemistry and Technology. ISUCT trained more than 35,000 engineers, about 1,000 Candidates of Science, and over 90 Doctors of Science during years of its existence.Currently the Ivanovo State University of Chemistry and Technology takes the 11th place in the rating of National Universities and Institutes.

The formation of complexes of nickel(II) with L-homoserine at 298.15 K and ionic strengths I = 0.5, 1.0, and 1.5 (KNO3) are investigated by potentiometry and calorimetry. Standard characteristics of studied equilibria (log K°, ΔrG°, ΔrH°, and ΔrS°) are determined. © 2016, Pleiades Publishing, Ltd.

The problem about the role of the coordinated exobidentate ligand in the formation of dimeric structures of sulfonated cobalt phthalocyanine derivatives is considered. The size of the peripheral substituent of the macrocycle and remoteness of the ionogenic group from the macrocycle play the key role in the formation of dimers of a specified type. As the extension of the peripheral substituent of the macrocycle increases, the stability of dimeric associates of the Н-type decreases and that of the associates formed due to the donor—acceptor interaction (J- and Т-aggregates) increases. The latter can be stabilized by hydrogen bonds at the periphery of the macromolecule. A series of catalytic activity of the macrocycles under study is inverted compared to the series of stability of the H-dimers. © 2016, Springer Science+Business Media New York.

The protolytic equilibria in solutions of complexones, derivatives of ethylenediamine-N,N,N',N'-tetraacetic acid, were studied. The standard thermodynamic characteristics of step dissociation of these diamine complexones were calculated and interrelated with the structural features of these compounds. © 2017, Pleiades Publishing, Ltd.

It is shown that the boundary curves of liquid equilibria in binary systems characterize the temperature–concentration boundary of the existence of homogeneous mixtures whose formation is not accompanied by changes in the Gibbs energy of the system and are a combination of two branches that do not convert into each other but intersect at the temperature of homogenization of a mixture of critical composition. The phase diagrams of a number of water–organic solvent systems are analyzed to determine the thermodynamic particularities of the latter. © 2017, Pleiades Publishing, Ltd.

The effect of the mixture was analyzed on the electrophysical parameters and emission spectra of CF2Cl2/Ar and CF2Cl2/He plasma. Data on the gas temperature and reduced electric field intensity are obtained. Based on the analysis of the plasma emission spectra, it is suggested that the dilution of CF2Cl2 with argon or helium, even in a 1-to-1 ratio, does not cause significant changes in the concentration of Cl atoms. © 2017, Pleiades Publishing, Ltd.

The effect of argon and helium additives on the kinetics of GaAs etching in high-frequency (HF) CF2Cl2 plasma has been analyzed. It is shown that dilution of the CF2Cl2 with argon or helium at a 1: 1 ratio insignificantly decreases the etching rate. An application of the bias power onto a substrate holder leads to. © 2017, Pleiades Publishing, Ltd.

The structural and thermodynamic characteristics of amide solvents are calculated with different types of molecular self-assembly through hydrogen bonding. Under a model-based approach, the specific and nonspecific components of the total energy of intermolecular interactions are identified for primary, secondary, and tertiary amides of carboxylic acids. It is found that similarly to water, primary amides have a network of hydrogen bonds and belong to the class of liquids characterized by an increase in nonspecific interactions with temperature. In secondary amides with the chain self-assembly, the contribution of these interactions is practically independent of temperature, and in tertiary amides it decreases with an increase in temperature. The molar values of the specific and nonspecific components are used to analyze the intermolecular interactions and the structural properties of amides with different degrees of N-substitution. © 2012 Pleiades Publishing, Ltd.

Methods of measuring the characteristics of molding masses for extrusion are classified. It is suggested that the measurable properties be divided into two groups, one including structural mechanical properties and the other including rheological properties. For estimating the suitability of a molding mass for extrusion of catalysts of preset shape, it is necessary to carry out an integrated analysis of the properties of the mass. The optimum parameters of molding masses have been determined. © Pleiades Publishing, Ltd., 2012.

Water in pure silica zeolites (zeosils) may behave as a "bumper" by absorbing mechanical energy of the intruded water, as a "spring" by restoring after extrusion of the energy spent in intrusion, or as "shock absorber" by dissipating the energy. The understanding of how the structure and topology of the zeosils are responsible of such behavior has not yet been fully clarified. Molecular dynamics and molecular mechanics simulations of IFR- and TON-type zeosils have been performed in an attempt to elucidate the energetics of these materials after water intrusion-extrusion. We aim our simulations to capture the experimentally observed "bumper" and "spring" water-zeosil behavior of IFR and TON, respectively. The excess energy with respect to dry zeosil was calculated, and this relates to the energetic response of the zeosil after water intrusion. We found that the excess energy of water-TON is larger than the energy of bulk water at any loading. The small opening of the TON channel prevents the formation of energetically stable bulky water clusters. The water content was shown to be stabilized on a certain loading range in water-IFR. It was shown that any silanol defects in IFR framework channels stabilize systems. Defect positions (silanol groups), which make the water-IFR system energetically stable, are found. Silanol groups increase the hydrophilicity of IFR-type zeosil, initially hydrophobic. There are two factors explaining the bumper behavior (under high pressure, water penetrates into the zeosil channels and remains there even after the pressure is released) of water-IFR systems: channel size and hydrolisis leading to framework breaking under large hydrostatic pressure. Silanol groups in channels are centers of water clusterization. The chemical stability of TON framework and its small channel size explain its spring behavior. © 2011 American Chemical Society.

The gas-phase molecular structure of μ-oxo dimer of aluminium(III) porphyrin, (AlP)2O, has been studied for the first time by density functional theory calculations using the B3LYP and M06 functionals and triple-ζ valence basis sets. The molecule has two conformers with equilibrium structures of D 4d and D 4h symmetries with parallel macrocycles and aluminium-oxygen distances of 1.680-1.684 Å (M06/cc-pVTZ). The aluminium atom lies out of the plane of the four central nitrogen atoms and forms a square-based pyramid with them, with the following parameters (M06/cc-pVTZ): r(Al-N) = 2.030-2.031 Å, r(N·· ·N) = 2.803-2.804 Å (the side of the pyramid base), z(Al)-z(N) = 0.434-0.446 Å (the height of the pyramid). © 2013 Springer Science+Business Media New York.
