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 ...
Imaging FTIR microscopy – technique for rapid screening of plant cell walls
(University of Belgrade, Institute for Biological Research “Siniša Stanković”, National Institute of Republic of SerbiaSerbian Society for Microscopy, Serbia, 2019)
It has been shown that xylan is oriented in parallel to the cellulose and more or less parallel to the
axis of a cell wall, in isolated CW fragments from maize leaves. There was also a clear indication of
lignin orientation ...

The examination of ecotoxic effect of folic acid based carbon dots on maize
(University of BelgradeTechnical Faculty in Bor, 2019)
Carbon dots (CDs) are popular and emerging nanomaterial which found application in many fields such as drug delivery, optoelectronic, and imaging due to their high solubility, low cost and easiness of their functionalization. ...
A Stochastic Theory of Wavelets
(Mathematical Institute of the Serbian Academy of Sciences and ArtsInstitute of Physics Belgrade, 2019)
The term wavelet implies a function generating base for decomposition of the finite energy signals both in spatial and in frequency domain concurrently. Construction of wavelets that have compact support and arbitrary high ...
Coating of cerium oxide nanoparticles with different carbohydrates and their application on plants
(Faculty of Technology, University of Novi Sad, 2019)
Cerium oxide nanoparticles (nCeO2) are nanomaterial with various applications in biomedicine, electronics and cosmetics. The aim of this research was to improve their low suspension stability by coating with carbohydrates ...
Structural characterisation and orientation of cell wall polymers in Arabidopsis thaliana stem
(Insitute for Nature Conservation of SerbiaFaculty of Science and Mathematics, Niš, 2019)
Plant cell walls are composed of a framework of cellulose microfibrils that are
interconnected with heteropolysaccharides (lignin, hemicelluloses) in a specific
manner. Plant cell walls form a large part of the plant ...
