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 ...
Electrodeposition and characterization of Fe-Mo alloys as cathodes for hydrogen evolution in the process of chlorate production
(Srpsko hemijsko društvo, Beograd, 2005)
Fe-Mo alloys were electrodeposited from a pyrophosphate bath using a single diode rectified AC current. Their composition and morphology were investigated by SEM, optical microscopy and EDS, in order to determine the ...
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 ...
On the kinetics of the hydrogen evolution reaction on Ni-MoOx composite catalysts in alkaline solutions
(Srpsko hemijsko društvo, Beograd, 2012)
MoO3 particles were co-deposited with Ni onto smooth or rough Ni supports from modified Watt baths of different compositions. Morphology and composition of the electrodeposits were characterized by means of cyclic voltammetry, ...
Ni-MoO2 composite cathodes for hydrogen evolution in alkaline solution. Effect of aging of the electrolyte for their electrodeposition
(Srpsko hemijsko društvo, Beograd, 2013)
In this work, the effect of aging of the electrolyte in the electrodeposition of Ni MoO2 composite coatings on their morphology (scanning electron microscopy), chemical composition (energy-dispersive X-ray spectroscopy), ...
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, structures and electronic properties of Co(III) complexes with 2-quinolinecarboxaldehyde thio- and selenosemicarbazone: A combined experimental and theoretical study
(Srpsko hemijsko društvo, Beograd, 2017)
Cobalt(III) complexes derived from thio-and selenosemicarbazone ligands have been studied to elucidate the nature and consequences of S to Se substitution on their possible biological activity. Solid state structures of ...
Hydro- and solvothermally-prepared ZnO and its catalytic effect on the photodegradation of Reactive Orange 16 dye
(Srpsko hemijsko društvo, Beograd, 2014)
In this work, zinc oxide powders were obtained by two different techniques: hydro- and solvothermal synthesis starting from Zn(NO3)(2) and Zn(CH3COO)(2), respectively. The influence of synthetic procedure on the structural, ...
Corrected accelerated service life test of electrodeposited NiSn alloys and Ni as cathodes for industrial alkaline water electrolysis
(Srpsko hemijsko društvo, Beograd, 2019)
The "corrected accelerated service life test for hydrogen evolution reaction" (CASLT-HER), designed for application of certain electrode materials as cathodes in the cell for alkaline water electrolysis in 30 % KOH at 80 ...
Expression, purification and characterization of cellobiose dehydrogenase mutants from Phanerochaete chrysosporium in Pichia pastoris KM71H strain
(Srpsko hemijsko društvo, Beograd, 2020)
Production of soluble cellobiose dehydrogenase (CDH) mutant proteins previously evolved on the surface of S. cerevisiae yeast cells was established for use in biosensors and biofuel cells. For this purpose, mutant cdh genes ...
