Abstract In the presented research work, the kinetics and mechanism of the deposition process of thin iron, selenium and Fe-Se films have been studied by recording a cyclic and linear polarization curves by potentiodynamic method using Pt and Ni electrodes. Individual and co-deposition potential areas of the components of the electrolyte on the Pt electrode […]
Abstract The interaction of 1 mol aminoethane acid with 1 mol of allyl chloride and 1 mol of (β-chlor)allyl chloride in an aqueous solution of sodium hydroxide (pH12) leads to the synthesis of the new monomer – N-allyl-N(β-chlor)allylethanic acid (AEA) with a yield of 50%. During polymerization of AEC (T=60-70) in aqueous solution in the […]
Abstract This study deals spectrophotometric analysis of the multi-ligand complex of zirconium (IV) with stilbazole and cetylpyridinium chloride. Dichloroethane was selected as the extragent and acetonitrile as the dispersant solution. Optimal conditions for the complex formation were identified. The results of the extraction process and complex formation were calculated statistically withPlackett Burman design and central […]
Abstract Network polymer hydrogels with high swelling effect were synthesized by using of ultraviolet crosslinking, with crosslinking agent N,N'-methylene-bis-acrylamide with chitosan an average molecular weight of 100-300 kDa t. The amount of crosslinking agent made up 10% of chitosan weight. The gel structure was studied using FTIR and the mechanism of the cross-linking process identified. […]
Abstract The influence of the graphite concentration on the main physical-mechanical properties of nanocomposites based on such polyolefin as high density polyethylene, low density polyethylene and polypropylene is considered. Properties such as tensile yield stress, ultimate tensile stress, and ultimate bending strength, elongation at break, heat resistance, flexural strength, MFI, and melting points are analysed. […]
