Far-infrared spectroscopy of PbTe doped with iron
(Belgrade : Serbian Chemical Society, 2002)
Far infrared reflection spectra, at room and liquid nitrogen temperature, of PbTe single crystals doped with iron are presented. Plasma minima were observed at about 160 cm–1 and 180 cm–1 for room and liquid nitrogen ...
On the kinetics of the hydrogen evolution reaction on zinc in sulfate solutions
(Belgrade : Serbian Chemical Society, 2001)
The kinetics and mechanism of the hydrogen evolution reaction (her) were studied on zinc in 1.0 mol dm-3 Na2SO4 at 298 K, in the pH range 4.4 - 10. It was found that a combination of classical potentiostatic steady-state ...
On the kinetics of the hydrogen evolution reaction on Ni-MoOx composite catalysts in alkaline solutions
(Belgrade : Serbian Chemical Society, 2012)
MoO3 particles were co-deposited with Ni onto smooth or rough Ni supports from modified Watt’s baths of different compositions. Morphology and composition of the electrodeposits were characterized by means of cyclic ...
Determination of the zinc and cadmium contents in low-alloyed tin
(Belgrade : Serbian Chemical Society, 1999)
The method of anodic linear sweep voltammetry (ALSV) has been used to determine the content of Zn and Cd (up to 4% w/w) in eutectic type binary alloys with Sn. The alloy samples were prepared by casting. The effect of the ...
Maltose-mediated, long-term stabilization of freeze- and spray-dried forms of bovine and porcine hemoglobin
(Belgrade : Serbian Chemical Society, 2019)
Slaughterhouse blood represents a valuable source of hemoglobin, which can be used in the production of heme-iron based supplements for the prevention/treatment of iron-deficiency anemia. In order to obtain a stable ...
Biodiesel synthesis and kinetic analysis based on MnCO3/Na silicate as heterogeneous catalyst
(Belgrade : Serbian Chemical Society, 2018)
Тhe MnCO3/Na silicate (Mn/Na/Si mole ratio of 4.65:1:1.65) catalyst in the form of solid particles with diameter of 0.99–1.99 mm was used as a catalyst for transesterification of soybean oil in batch autoclave at different ...
Ni-MoO2 composite cathodes for hydrogen evolution in alkaline solution: Effect of aging of the electrolyte for their electrodeposition
(Belgrade : Serbian Chemical Society, 2013)
In this work the effect of aging of the electrolyte for electrodeposition of Ni-MoO2 composite coatings on their morphology (scanning electron microscopy), chemical composition (energy-dispersive X-ray spectroscopy), ...
Mechanochemical synthesis and electrical conductivity of nanocrystalline δ-Bi2O3 stabilized by HfO2 and ZrO2
(Belgrade : Serbian Chemical Society, 2009)
A powder mixture of α-Bi2O3 and HfO2, in the molar ratio 2:3, was mechanochemically treated in a planetary ball mill under air, using zirconium oxide vials and balls as the milling medium. After 50 h of milling, the ...
Influence of various cosolvents on the calcium oxide-catalyzed ethanolysis of sunflower oil
(Belgrade : Serbian Chemical Society, 2019)
Ten organic solvents (triethanolamine, diethanolamine, ethylene glycol, methyl ethyl ketone, n-hexane, triethylamine, ethylene glycol dimethyl ether, glycerol, tetrahydrofuran and dioxane) were applied as cosolvents in the ...
Copper electrodeposition from a copper acid baths in the presence of PEG and NaCl
(Belgrade : Serbian Chemical Society, 2001)
Copper electrodeposition from copper acid solutions containing PEG and NaCl has been investigated onto Cu(111), Cu(100) and polycrystalline copper electrodes using polarization and EIS measurements. The adsorption of ...
