Sintering and Phase Transition of the ZnTiO3 Nano Powder Dilatometric Data Deconvolution
(Belgrade : ETRAN SocietyBelgrade : Academic Mind, 2022)
Sintering and phase transition are often superimposed at dimensional change diagram recorded during heating. Phase transition kinetic is thus hard to deconvolute due to the superposition of the sintering and phase transition ...

Tokom 80-ih godina 20. veka saradnici Centra za multidisciplinarne studije Univerziteta u Beogradu i Srpske akademije nauka i umetnosti realizovali su prvu fazu projekta u okviru kojeg su ispitivane opeke monumentalnih ...
Populus x euramericana tension wood as a model for selection of microscopic methods for rapid screening of cell wall structure in the analysis of plant stem properties
(Department of Biology and Ecology, Faculty of Sciences and Mathematics, University of Niš Institute for Nature Conservation of Serbia, 2022)
The plant cell wall (CW) is a cell compartment lying outside the plasma
membrane forming a continuum throughout the plant body. The composition of
CWs varies between plant species and cell types, while changes in CW ...
The effect of pH on visible-light photocatalytic properties of pseudobrookite nanoparticles
(Belgrade : Materials Research Society of Serbia, 2019)
In this study, pseudobrookite (Fe2TiO5) nanoparticles were fabricated by a modified sol-gel method using Fe(NO3)39H2O and Ti(OC3H7)4 as starting reagents and ethanol as solvent. Oxalic acid was used as a chelating agent ...
Structural, optical and photocatalytic properties of BiFeO3 nanoparticles
(Institute for Multidisciplinary Research, University of Belgrade Kneza Višeslava 1, 11000 Belgrade, Serbia, 2019)
BiFeO3 (BFO) precursor powder was synthesized by ultrasound asissted sol–gel route at relatively low temperature, starting from Bi-nitrate, Fe-nitrate, and ethylene glycol. Structural, optical, and photocatalytic properties ...
