Polymer-based nanocomposites NBR in the presence of nanoscale zinc oxide powder were obtained the crosslinking agent disulfochlorid benzene (DSCB) and carbon black. The role of ZnO nanopowders and DSCB in NBR systems NBR+ZnO+DSCB and NBR+ZnO+DSCB+F324 with radiation, chemical exposure. With the help of physico-chemical and spectral methods shown ch...
Investigated the role of polymer peroxide (1,4-bis-tret butyl peroxy isopropyl benzene) and triazine
compounds (6-bis-trichloromethyl sym-triazine, 2-phenyl-4) under heating in hydrogenated butadiene nitrile
rubber (HNBR) systems. The changes in HNBR's molecular structure when polymer peroxides and triazine
compounds are present, as demonstrated by...
Graphene oxide (GO) nanosheets were functionalized with Schiff base and reduced Schiff base. Covalent and non-covalent functionalized GO nanostructures have been tested for the removal of pesticides with different chemical structures and properties (e.g., Epoxiconazole, Dimethomorph, Cyprodinil, Chlorothalonil, Acetochlor, Trifluralin) from aqueous...
Using the slow evaporation process, we successfully synthesized a novel hybrid material, (C6H7ClN)[HgCl3], which was subsequently characterized through various physicochemical methods. The crystal structure was determined within the triclinic system, specifically in space group P-1. The packing arrangement exhibited alternating di-trichloromercurat...
We herein reported the synthesis of dihydropyrimidines 1 and 2 on the basis of nitro and brominated salicylaldehyde derivatives by Biginelli reaction in microwave conditions in the presence of cheap low toxic copper triflate. The structures of both compounds were investigated by the X-ray single-crystal diffraction method. The presence of non-coval...
Using the conditions obtained from various simple and complex models, the energy of the surface area was calculated with the help of electronic structural transitions and thermo-sublimation approximations occurring in yttrium oxide nanoparticles irradiated with different energy deuterium ions. The depth of penetration of deuterium ions of different...
The kinetic and temperature dependencies of the conversion of hexane to gas and liquid oxide products on the surface of the nano-Al2O3 catalyst in the homo and hetero phase were investigated and compared. The rate of hexane conversion in air in different phases at temperature ∆T = 180–2000 C was determined ((a) 10–15% from the homo phase in the het...
Herein, we have developed simple, one-stage and cheap precipitation methods for synthesizing Ca(OH)2 and CaCO3 nanoparticles with average sizes of (75 ± 8)0.95 and (70 ± 10)0.95 nm, respectively. Both methods are based on CaCl2 precursor and cheap polyethylene glycol (PEG) surfactant. The influence of the precipitation conditions on the size and mo...
The radiation-thermocatalytic and thermocatalytic processes of water decomposition on the surface of n-ZrO 2-n-SiO 2 systems have been investigated. The kinetics of the accumulation of molecular hydrogen during radiolytic processes of water decomposition in the systems under study has been studied. The values of the rates and radiation-chemical yie...
We report herein the synthesis of new derivatives of dihydropyrimidine on the basis of 2,4,6-trimetoxybenzaldehyde, which was further regioselectively oxidized in the presence of cerium ammonium nitrate (CAN) with the formation of 5-acetyl-6-methyl-4-(2,4,6-trimethoxyphenyl)pyrimidin-2(1H)-one. The structures of both novel compounds were investigat...
Correction for ‘Synthesis, crystal structure and antibacterial studies of dihydropyrimidines and their regioselectively oxidized products’ by Alakbar E. Huseynzada et al. , RSC Adv. , 2021, 11 , 6312–6329, DOI: 10.1039/D0RA10255E.
The syntheses and investigations of new biologically active derivatives of dihydropyrimidines by Biginelli reaction in the presence of copper triflate are reported. Due to the fact that salicylaldehyde and its derivatives under Biginelli reaction conditions can lead to the formation of 2 types of dihydropyrimidines, the influence of copper triflate...
The interaction of plasma and its encompassing materials with one another is one of the principle designing issues of fusion reactors. Tungsten is considered one of the primary candidate materials in fusion applications due to its superior properties. In this work, we doped vanadium carbide powders to the tungsten matrix to enhance the properties o...
The effect of γ-irradiation on the crosslinking process of nitrile butadiene rubber (NBR) with the participation of 4-dichloro 6-diethylamino-simmtriazine (DChDEAST) and 2,4-dimethylphenyl maleimide (DMPhM) was investigated. The molecular structure of the binary systems NBR + DChDEAST and NBR + DMPhM was determined by Fourier spectroscopy. Fourier...
In the present work, the structure and thermal properties of nanocomposites based on nanometal oxides (ZnO, Al2O3, ZrO2) and aromatic disulphochloride benzene compounds in a butadiene nitrile rubber (NBR) matrix that are obtained by gamma-rays processing have been investigated. Structural changes of nanocomposites depend on the type of used nanopar...
Research project, carbon blacks were produced by furnace (S324) and channel(K354) methods were added to elastomer mixture and vulcanization process carried out with gamma rays and physical-chemical properties are learned. Two types of fillers with different amounts were included to composite material which formed by based on butadiene nitrile rubbe...
The crosslinking activation ability of nanoscale metal oxides depends not only on the type of crosslinking agent, but also on the type of rubber used. Therefore, it was of interest to clarify the role of nano-sized metal oxides, which differ in activity when nitrile-butadiene rubber (NBR) is crosslinked with with benzene-1,3-disulfonyl chloride (DS...
The increase of irradiation temperature by gamma-rays of emulsion isoprene nitrile elastomer in the range of 298-423 K is accompanied by the significant increase of crosslinking rate and strength deterioration of unfilled cures at the same time.By the method of sol-gel analysis the output dependences of the mesh chains (1/Mc) are de-terminedof cros...
