(Beograd : Savez pedagoških društava Jugoslavije, 2013)
Правилником о школском простору из 1990. године предвиђено је да се настава хемије одвија у кабинет-лабораторији, тј. у посебно опремљеном простору којег чини радна и припремна просторија. Циљ истраживање, чији су резултати ...
Nanostructured Fe2O3/TiO2 thick films
(Programme and Book of Abstracts of The Second Conference of The Serbian Ceramic Society, 2013)
Thick films of nanostructured pure TiO2, -Fe2O3, Fe2O3/TiO2 (ratio 2:3 and 3:2) and a hetero-junction in the form of a TiO2 layer over a Fe2O3 layer have been fabricated by screen printing technology on a glass substrate. ...
Customizing nanotubular titania for photocatalytic activity
(Belgrade : Institute of Technical Sciences of SASA, 2018)
Semiconductor TiO2 photocatalysis is a heterogeneous catalysis, where the photons of the sun or artificial light source are activating the catalyst that enters in reactions. The targeted real-world applications are in ...
Photocatalytic degradation of textile dye with hydrothermally modified nanoanatase
(Institut za multidisciplinarna istraživanja, Belgrade, Serbia, 2015)
The environmental friendly materials based on titanium oxides are often chosen
for the industrial application due to their extraordinary characteristics (biological
and chemical stability, good photocatalitic activity, ...
Photocatalytic properties of hydro-and solvothermaly prepared nanosized ZnO
(Institute for Multidisciplinary Research, University of Belgrade, 2013)
Two salts of Zn were used as starting materials: Zn(CH3COO)2·2H2O for
solvothermal and Zn(NO3)2·6H2O for hydrothermal treatment. Initially,
Zn(CH3COO)2·2H2O was dissolved in ethylene-glycol in the presence of PVP ...
