Stream section types of the Danube River in Serbia according to the distribution of macroinvertebrates
(Springer, New York, 2013)
The aim of this study was to use the data on the distribution of aquatic macroinvertebrates obtained from 14 sites within a 413 km long stretch of the Danube River in Serbia to show the relevance of the bordering zone ...
Lipase production by Yarrowia lipolytica using olive oil processing wastes as substrates
(Srpsko hemijsko društvo, Beograd, 2013)
In this study, the solid and liquid wastes from the olive oil processing industry were evaluated as substrates for Yarrowia lipolytica growth with the aim of lipase production. Olive mill wastewater and olive oil cake ...
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 ...

An attempt to produce NiFe2O4 powder from electrodeposited Fe-Ni alloy powders by subsequent recrystallization in air
(Springer, Dordrecht, 2010)
The electrodeposition of the Fe-Ni powders from citrate-ammonium chloride containing electrolytes for different Ni/Fe ions concentration ratios at pH 4.0 was investigated by the polarization measurements. The morphology, ...
Combined FTIR and SEM-EDS study of Bi2O3 doped ZnO-SnO2 ceramics
(Wiley, Hoboken, 2008)
The effects of Bi2O3 addition on the phase composition, microstructure and optical properties of ZnO-SnO2 ceramics were investigated. Starting powders of ZnO and SnO2 were mixed in the molar ratio 2:1. After adding Bi2O3 ...
