The ionic equilibrium in the CuSO4-H2SO4-H2O system and the formation of the honeycomb-like structure during copper electrodeposition
(Srpsko hemijsko društvo, Beograd, 2008)
The ionic equilibrium of the species in the CuSO4-H2SO4-H2O system was employed to systematize the conditions of copper electrodeposition leading to the formation of the honeycomb-like structure. The reason why CuSO4 ...
Temperature dependence of the kinetics of oxygen reduction on carbon-supported Pt nanoparticles
(Srpsko hemijsko društvo, Beograd, 2008)
The temperature dependence of oxygen reduction reaction (ORR) was studied on highly dispersed Pt nanoparticles supported on a carbon cryogel. The specific surface area of the support was 5 17 m(2) g(-1), the Pt particles ...
Flavonoids from the aerial parts of Onobrychis montana subsp scardica
(Srpsko hemijsko društvo, Beograd, 2008)
Rutin (1, main constituent) and two flavone C-glycosides, vitexin (2) and vitexin 2 ''-O-alpha-rhamnopyranoside (3) were isolated from the aerial parts of Onobrychis montana subsp. scardica. They were identified by H-1-NMR, ...
An EPR spin-probe and spin-trap study of the free radicals produced by plant plasma membranes
(Srpsko hemijsko društvo, Beograd, 2005)
Plant plasma membranes are known to produce superoxide radicals, while the production of hydroxyl radical is thought to occur only in the cell wall. In this work it was demonstrated using combined spin-trap and spin-probe ...
Oxygen reduction at platinum nanoparticles supported on carbon cryogel in alkaline solution
(Srpsko hemijsko društvo, Beograd, 2007)
The oxygen reduction reaction was investigated in 0.1 M NaOH solution, on a porous coated electrode formed of Pt particles supported on carbon cryogel. The Pt/C catalyst was characterized by the X-ray diffraction (XRD), ...
Electrochemical oxidation of methanol on Pt/(RuxSn1-x)O-2 nanocatalyst
(Srpsko hemijsko društvo, Beograd, 2013)
Ru-doped SnO2 powder, (RuxSn1-x)O-2, with a Sn:Ru atomic ratio of 9:1 was synthesized and used as a support for Pt nanoparticles (30 mass % loading). The (RuxSn1-x)O-2 support and the Pt/(RuxSn1-x)O-2 catalyst were ...
Electrodeposition and characterization of Ni-MoO2 composite coatings as cathodes for the hydrogen evolution reaction in alkaline solution
(Srpsko hemijsko društvo, Beograd, 2013)
Composite Ni-MoO2 coatings were prepared and characterized with respect to their possible application as electrocatalysts for the hydrogen evolution reaction (HER) in alkaline solution. The composites were electrodeposited ...
The influence of substituted aromatic aldehydes on the electrodeposition of Zn-Mn alloy
(Srpsko hemijsko društvo, Beograd, 2013)
Additives are necessary in the electrodeposition of Zn-Mn alloys at high current densities, in order to reduce the hydrogen evolution reaction and prevent dendrite formation. The influences of two aromatic aldehydes, ...
The sorption of inorganic arsenic on modified sepiolite: the effect of hydrated iron(III) oxide
(Srpsko hemijsko društvo, Beograd, 2014)
The sorption of inorganic arsenic species, As(III) and As(V), from water by sepiolite modified with hydrated iron(III) oxide was investigated at 25 degrees C through batch studies. The influence of the initial pH value, ...
Synthesis and characterization of mu-hydroxido- and mu-polycarboxylato-bridged iron(III) complexes with 2,2 '-bipyridine
(Srpsko hemijsko društvo, Beograd, 2014)
Four novel polymeric iron(III) complexes with 2,2'-bipyridine (bipy) and different aromatic polycarboxylato ligands as anions of phthalic (pht), isophthalic (ipht), terephthalic (tpht) and pyromellitic (pyr) acid were ...
