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 ...
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), ...
Modification of the structural and optical properties of commercial ZnO powder by mechanical activation
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2006)
Mechanical activation was used as a method for modification of the structural and optical properties of commercial ZnO powder. For this purpose zinc oxide powder was mechanically treated by grinding in a high-energy ...
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 ...
Electrical properties of ZnO varistors prepared by direct mixing of constituent phases
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2006)
Varistor samples containing different amounts of constituent phases were prepared by direct mixing of constituent phases. Detailed electrical characterization was performed to explain the influence of minor phases (spinel ...
Reproducibility of age determination by scale and vertebra in pontic shad (alosa pontica eichwald, 1838), from the Danube
(Srpsko biološko društvo, Beograd, i dr., 2009)
Specimens of Pontic shad (Alosa pontica Eichwald, 1838) were collected during April and May of 2006 in the Danube River (rkm 863) just downstream of the Iron Gate (Djerdap) II dam. Twenty-eight scales and 30 vertebrae were ...

(Srpsko biološko društvo, Beograd, i dr., 2009)
A comparative study was carried out on the capabilities of the two species Paulownia elongata S. Y. Hu and Paulownia fortunei Hems. as biomonitors of atmospheric (and soil) heavy-metal pollution. Research on content of the ...
Mortality of red mullet (mullus barbatus linnaeus, 1758) on the Montenegrin shelf (south Adriatic) (vol 61, pg 493, 2009)
(Srpsko biološko društvo, Beograd, i dr., 2009)
Red mullet, Mullus barbatus Linnaeus, 1758, is an economically very important species in trawl fisheries in the Adriatic Sea. Material for analysis was collected from October 2002 until May 2004 with a bottom trawl net ...
