Multiple forms of superoxide dismutase in the apoplast and whole-needle extract of Serbian spruce [Picea omorika (Panč.) Purkyně]
(Serbian Biological Society, 2006)
Activity and isoenzyme composition of superoxide dismutase in the apoplast and whole-needle extract of Picea omorika (Panč.) Purkyně, was studied. Total SOD activity of the soluble fraction of the needle extract exceeded ...
The nature of structural changes in nanocrystalline ZnO powders under linear heating conditions
(Elsevier Sci Ltd, Oxford, 2004)
The nature of exothermal and irreversible structural changes observed during linear heating of nanocrystalline ZnO powders was investigated using differential scanning calorimetry, X ray, SEM and TEM analysis. Nanocrystalline ...

Morphology of Ni-Mo-O alloy powders electrodeposited from ammonium sulfate solutions / Morfologija prahova Ni-Mo-O legura istaloženih elektrohemijskim postupkom iz rastvora amonijum sulfata
(Belgrade, Serbia : Engineering Society for Corrosion, 2008)
The electro deposition of the Ni-Mo-O alloy powders from ammonium sulfate containing electrolytes of different Ni/Mo ions concentration ratios was investigated by the polarization measurements. In all electrolytes similar ...
Evolution of the microstructure of disperse ZnO powders obtained by the freeze-drying method
(Elsevier Science Sa, Lausanne, 2004)
Freeze-drying, as a cryochemical powder processing method is applied in the synthesis of ZnO submicrometer to narrosized powders. The process involves rapid freezing of the sprayed precursor solution, drying under vacuum ...
