Abstract The paper presents the application of facile one-step “Dip and Drying –DDM” method for deposition of different transition metals (Fe, Co and Ni) on nickel foam (NF) substrates. The obtained modified electrodes are tested as bi-functional electrocatalysts for overall water splitting reaction. The influence of the used metal salts (chloride, sulphate or nitrite) on […]
Abstract A new organic reagent based on benzoylacetone, 3-(4'-fluorophenylimine) -1 –phenylbutanone – 1 was synthesized and its crystal structure determined by X-ray structural analysis. Reagent crystals are monoclinic: a=6.4520(6) Ǻ, b=28.685(2) Ǻ, c=7.2003(6) Ǻ, α=90°, β=91.163(2)°, γ=90°, V=1332.3(2)Å 3, space group P21/n, Z=4. Results of X-ray diffraction analysis showed that the reagent molecule in the […]
Abstract The dynamics of the accelerated formation of corrosion products of equipment in the process of obtaining diesel and oil fractions from sour oil with a high concentration of resinous asphaltic substances and derivatives of petroleum acids are investigated in this work. The following experimental data is obtained: the genesis of the phase composition during […]
Abstract The thermodynamic properties of the Bi-Te system were studied in the 55–65 at% Te compositions interval and temperatures 300–450 K by using the electromotive forces method. Relative partial molar functions of bismuth in the alloys were calculated. Based on the potential-forming reactions for Bi2Te3 and Bi4Te5 compounds, a mutually consistent set of standard thermodynamic […]
Abstract By the method of electrosynthesis with the simultaneous extraction in xylene obtained CdTe and ZnSe nanoparticles in the size of 2-3 nm by using of electrolytes based on (NH4OH, CdSO4 and Na2TeO3) and (H2SO4, H2SeO3, ZnSO4). The mechanism formation of nanoparticles consists of the electrochemical stage formation of telluride or selenide ions and of […]
Abstract Various coupling schemes are applied to smaller to heavy atoms to describe atomic structure and investigate atomic spectra. jj-coupling is important for heavy atoms in which spin-orbit interactions are dominant over the electrostatic interactions. Here jj-terms and J levels are determined for the nonequivalent fnfn’ (n & n’ = 1-2) electrons from the analysis […]
