Assessment of the faecal contamination along the Sava River and identification of pollution sources
(Macedonian Ecological Society, 2016)
The contamination of water by faecal pollution leads to exposure to pathogens via drinking water
production, recreation or irrigation. However, monitoring of microbiological quality of surface waters
is quite neglected ...

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 ...
