Alumina powders as novel non-toxic insecticide against bean weevil (Acanthoscelides obtectus Say)
(6th International Scientific Agricultural Symposium „Agrosym 2015“, Jahorina, 2015)
Alumina powders were obtained by auto combustion method and calcined for 1 h at
temperatures ranging from 1000ºC to 1200ºC. X-ray powder diffraction analysis revealed an
overwhelming presence of γ–Al2O3 for the powder ...
Synthesis and X-ray structural analysis of complex formation with chalcogensemicarbazones of 8-quinolinecarboxaldehyde
(Serbian Chemical Society, 2015)
Three new complexes of cobalt with chalcogensemicarbazones of 8-quinolinecarboxaldehyde were synthesized and characterized by X-ray analysis, elemental analysis, NMR, IR spectroscopy and molar conductivity and magnetic ...
STRUCTURE AND CHARACTERIZATION OF BaTiO3-Ni(1-x)Zn(x)Fe2O4 COMPOSITES
(Institute for Multidisciplinary Research, University of Belgrade Kneza Višeslava 1, 11000 Belgrade, Serbia, 2015)
NiZnFe2O4 (NZF) powder was prepared by auto-combustion method starting from nickel, zinc and iron nitrates. Thermal treatment was performed at 1000 oC for 1 h after which the nickel ferrite powder was formed. Barium titanate ...

High PAR and UV-B radiation-induced differential responses in green and white leaf sectors of Pelargonium zonale in relation to sugar, antioxidative and phenolic metabolism
(Serbian Plant Physiology SocietyInstitute for Biological Research “Siniša Stanković” – National Institute of Republic of Serbia, University of Belgrade, 2015)
In this study we investigated the specific effects of high photosynthetically active radiation (PAR) and ecologically
relevant UV-B radiation (0.90 W m-2) on antioxidative, phenolic and sugar metabolism in variegated
Pelargonium ...
Restoration of longitudinal connectivity of the Danube River by the construction of free passages for migratory fish species at the Iron Gates dams
(University of Wisconsin - Madison,Oregon State University,University of Massachusetts Amherst, Holandija, 2015)
Synthesis of Alumina Powders and their Insecticidal Effect Against Acanthoscelides Obtectus Say
(Univerzitet u Novom Sadu, Tehnološki fakultet, 2015)
Alumina powders were synthesized by citrate/nitrate autocombustion method with
different citrate/nitrate molar ratios (0.5, 0.8 and 1.2). XRD analysis of the powders
calcined at 1200 °C for 1 h showed only the presence ...

(Faculty of Forestry, Belgrade, Serbia,, Beograd, Srbija, 2015)
Microbiological quality and the Sava River – the whole river survey
(Hellenic Microbiology Society, 2015)
Object of the research: Knowledge of the extent of faecal pollution of the Sava River is extremely important as many of the large settlements situated on the river bands discharge high quantities of untreated or improperly ...
The relationship of physicochemical properties and structure to the antioxidative activity of free amino acids in the aqueous Fenton system
(Serbian Plant Physiology SocietyInstitute for Biological Research “Siniša Stanković” – National Institute of Republic of Serbia, University of Belgrade, 2015)
Iron is essential for plant growth, metabolism of mitochondria and chloroplasts, and a wide assortment of enzymes. However, it is also involved in Fenton reaction that generates hydroxyl radical (HO•), the most reactive ...
