Structural, morphological and optical study of nanostructured TiO2/Fe2O3 thick film
(Bor : Technical Faculty, 2013)
Thick films of nanostructured TiO2 (60 wt%) and alpha-Fe2O3 (40 wt%) were fabricated by screen printing technology on an alumina substrate. Samples were sintered in the temperature range 750-1350oC in air. Thick film paste ...
Effects of vanadate on antioxidant systems in mycelium of fungus Phycomyces blakesleeanus
(Wiley, Hoboken, 2021)
Fungi represent the main route of vanadium’s entrance in ecosystem and are known to tolerate high concentrations of this transition metal. Despite it, its effects on antioxidant systems of fungi are not well-known. The aim ...

The structure of a mature stand and the following sapling stage in the process of planned regeneration on a site of a monodominant sessile oak forest (Quercetum petraeae Čer. et Jov. 1953., subass. tilietosum) in the NP ,,Đerdap”
(Institute of Lowland Forestry and Environment (ILFE), University of Novi Sad, Serbia, 2018)
The paper shows the structure of a mature stand, as well as the structure of the sapling stage that followed after the
planned regeneration on the experimental plot in a monodominant sessile oak site (Quercetum petraeae ...
Nanocrystalline iron-manganite (FeMnO3) applied for humidity sensing
(Belgrade : Institute for Multidisciplinary Research, 2019)
Nanocrystalline iron manganite was synthesized using a sol-gel self-combustion method with glycine as fuel, followed by calcination at 900 °C for 8 hours. Structural characterization was performed using X-ray diffraction ...
