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 ...
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 ...
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 ...
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 ...
Surface reconstruction during the adsorption/desorption of OH species onto Cu(111) and Cu(100) in O. 1 M NaOH solution
(Belgrade : Serbian Chemical Society, 2002)
The process of adsorption/desorption of OH- species onto Cu(111) and Cu(100) in 0.1M NaOH solution has been investigated by cyclic voltammetry and the potentiostatic pulse technique. Investigation of the electrochemical ...
Underpotential deposition of cadmium onto Cu(111) and Cu(110) from chloride containing solutions
(Belgrade : Serbian Chemical Society, 2001)
Underpotential deposition (UPD) of Cd onto the (111) and (110) faces of copper in chloride containing electrolyte has been investigated by cyclic voltammetry and the potentiostatic pulse technique. It was shown that the ...
Magnetic properties of nanostructured SiOo2:Eu3+ powders
(Belgrade : Serbian Chemical Society, 2006)
Eu-doped silica nanoparticles with different concentrations of europium (3% 6%and 15at.%) were prepared by a hydrothermal procedure. Light scattering measurements of the silica colloids as well as TEM microscopy, revealed ...
