Pollution of the environment with substances obtained in the production of oil and other products in var-ious industries forces us to take measures to solve environmental problems that have become relevant in recent years. Arenes, belonging to the class of petroleum-derived aromatic hydrocarbons,...

The effect of additives of nanofillers (NF) containing nanoparticles of copper (I) oxides stabilized by a polymer matrix of high-pressure polyethylene (PE) obtained by the mechano-chemical method on the structure and properties of metal-containing nanocomposites based on a mixture of highand...

Porous silicon is actively used in the fabrication of sensors and detectors because of its large specific surface area, which is an important characteristic for gas adsorption. To improve the operating parame-ters of the sensors and increase the stability of operation, a film of tin oxide was...

A homologous series of new Schiff base’s esters, 4-bromobenzylidene-4’-alkanoyloxyanilines were syn-thesized. The structure of the synthesized compounds was elucidated using IR and NMR spectroscopic techniques along with mass spectrometric method. Nine homologous members were prepared whereby the...

The purpose of this work is to develop a highly selective method for the photometric determination of iron (III) in environmental objects, in particular, in oil and oil products using hydroxyhalogenthiophenol (H2R) 2-hydroxy-5-chlorothiophenol, 2-hydroxy -5-bromothiophenol and...

This study is devoted to the synthesis of various ensembles on the basis of graphene oxide nanolayers and dihydropyrimidines and the investigation of their antimicrobial activity. The “building blocks” of ensembles, viz dihydropyrimidines were synthesized by the Biginelli reaction in the presence...

Using complex of physicochemical methods of analysis (DTA, XRD, MSA, as well as measurements of density and microhardness), the phase equilibria in the Sb2S3-Cr2Se3 system was studied and a phase diagram was con-structed. It is established that the system is quasi-binary and has eutectic type T-x...

The scientific paper is devoted to the electrochemical reduction of bismuth ions from citrate electrolytes. The kinetics and mechanism of the process and the influence of various factors on the electroreduction process of bismuth ions were studied by recording cyclic and linear polarization curves...

This communication presents the results of studies of coherently synchronized reactions of 2-picoline oxidation with hydrogen peroxide and nitrous oxide (I) in the gas phase. Optimal conditions for obtain-ing target products in these reactions are revealed. The influence of the process parameters...

Compounds of the argyrodite family are valuable environmentally friendly functional materials with mixed ion-electronic conductivity, thermoelectric, photovoltaic, optical, and other properties. This paper presents the results of a thermodynamic study of the Cu8GeS6 and Cu8GeSe6 compounds...

Based on benzylthioctane-2-ol, heterocyclic amines (piperidine, morpholine, hexamethyleneimine), and formaldehyde, new Mannich bases were synthesized. The reaction was carried out at a temperature of 45–500C for 3–4 h. in an equimolar ratio of starting compounds. The yield of target products was...

The increasing demand for aluminum around the world is increasing interest in developing alternative technologies for the production of alumina from non-bauxite sources, especially from clay. In this work, the extraction of aluminum from kaolin in the process of leaching using an aqueous solution...

A method for obtaining bromine-containing bicyclic unsaturated polyesters by the interaction of 1,4,5,6,7,7-hexabromobicyclo-[2,2,1]-hept-5-ene-2,3-dicarboxylic acid anhydride, propanetriol and ma-leic anhydride was developed. It was found that unsaturated polyethers synthesized by a two-step...

Recently, protein tyrosine phosphatase 1B (PTP1B) inhibitors have become the frontier as possible target-ing for anti-cancer and antidiabetic drugs. The contemporary observe represents a pc assisted version to in-vestigate the importance of precise residues within the binding web site of PTP1B with ...

Considering necessity of application of Schiff base ligands, containing hydrazone moiety, there were synthesized 2-hydroxy-1-naphtaldehyde acetylhydrazone and its metal complexes. A tridentate ligand with hydrazone moiety was synthesized on the basis of acetylhydrazine and 2-hydroxy-1-naphthoic...

A new class of active organic crosslinking agents for the vulcanization of NBR based on halogen-methyl-containing compounds has been found, allowing improvement significantly in the rheological and structural parameters of NBR. Gel content and Mooney viscosity in binary systems after...

The results of thermal studies of some derivatives of dithiophosphoric, xanthogenic, dithiocarbamic ac-ids are presented. The thermal parameters of the compounds were determined both in pure form and in the presence of iron and copper powders. Their chemical activity with respect to iron and copper ...

Modification of the applied Pt-containing catalysts with rare-earth metals is one of effective ways to in-crease their activity and resistance to thermal deactivation, which is associated with both an increase in thermal stability of the texture and structure of the carrier material and an increase ...
