Abstract After reviewing a number of researches that demonstrate the effectiveness of a number of compounds containing the acetylenic amine group as antimicrobials and antiproliferative activity, our goal is to prepare new acetylenic amine derivatives from the compound 2-(2-((2,6- dichlorophenyl)amino)phenyl)acetic acid using the Mannich reaction by the react salt of a carboxylic acid with propargyl […]

Abstract Complex copper-based chalcogenides are a significant environmental-friendly functional material that has great application potential due to their interesting thermoelectric, photoelectric, optical, and other properties, as well as their ionic conductivity. Analysis of numerous studies shows that improving the application characteristics of these compounds is associated with manipulating their structure and composition. An effective solution […]

Abstract The charge transfer processes in nonpolar media are considered in the work. The nonpolar medium is regarded as a field of random forces or impulses, and this field acts on the reacting particles. The interaction of reagents with the medium is described through the function of fluctuation of the impulse of a particle of […]

Abstract This work presents studies to study the nucleation and growth mechanism of electrochemical Ni- Mo films suitable for the decomposition reaction of water as an electrocatalyst, in which the value of the potential established from polarization measurements was maintained constant. Optimal conditions for the electrochemical synthesis of the Ni-Mo alloy on the surface of […]

Abstract In this work, seven new Schiff bases were obtained in two ways. In method (A), an equimolecular aqueous solution of glucose and an alcoholic solution of amine were refluxed for three hours, and in method (B), a deep eutectic solvent (Reline), prepared from one mole of choline chloride and two moles of urea,was used […]

Abstract The aim of this work was to create new ligand complexes and evaluate their effectiveness against certain strains of bacteria. A Brucker Tensor 27co FTIR spectrophotometer was used to record the infrared spectra. Elemental analysis (C, H, N) was carried out on an AA670 atomic absorption spectrophotometer to determine mineral content, and the conductivity […]

Abstract The number of -arylamino-2-oxy-5-methylpropiophenones has been synthesized by reacting of - dimethylamino-2-oxy-5-methylpropiophenone hydrochloric acid salt with aniline derivatives in order to use these compounds as stabilizers for polyethylene. It was shown that the thermal stability of the compounds, depending on the nature of the substituent in the aniline fragment of the molecule was observed […]

Abstract This study includes the preparation and characterization of new compound (4-bromo-5-(N-((4- chlorophenyl) (1,1-dioxide-3-oxobenzo isothiazol-2(3H)-yl)methyl)sulfamoyl)-2-((furan- 2-ylmethyl)amino)benzoic acid) from the reaction of furosemide, Saccharin and p-bromo benzaldehyde in a molar ratio 1:1:1 in ethanol. All the complexes are prepared from the reaction of Mannich bases with metal nitrate salts of transition metals such as Co, Ni, […]
