Synthesis, Characterization, Catalytic Activity, and DFT Calculations of Zn(II) Hydrazone Complexes
(MDPI, 2020)
Two new Zn(II) complexes with tridentate hydrazone-based ligands (condensation products of 2-acetylthiazole) were synthesized and characterized by infrared (IR) and nuclear magnetic resonance (NMR) spectroscopy and single ...
The Balkan Macrophyte Index (BMI) for Assessment of Eutrophication in Lakes
(Sofia, Bulgaria : Prof. Marin Drinov Academic Publishing House, 2020)
Aquatic plants have long been used as indicators for nutrient enrichment in lakes. In the Mediterranean, however, the process of developing and intercalibrating macrophyte assessment methods for lakes has lagged behind ...
Numerical simulation of fluid-structure interaction between fishing wobbler and water
(Niš, Serbia : University of Niš, 2020)
This paper deals with modeling, discretization, and numerical analysis of the two-way fluid-structure interaction between a fishing wobbler and a water stream. The structural domain is an assembly of several bodies that ...
Artificial intelligence-based optimization of a bimorph-segmented tapered piezoelectric mems energy harvester for multimode operation
(MDPI, 2021)
This paper presents a study on the design and multiobjective optimization of a bimorph-segmented linearly tapered piezoelectric harvester for low-frequency and multimode vibration energy harvesting. The procedure starts ...

(MDPI, 2020)
This study investigated the quality of Kupa River sediment using sequential extraction,
ecological risk, and contamination indexes (Risk assessment code, Index of geoaccumulation,
Enrichment factor, Ecological risk factor, ...
Extraction kinetic of some phenolic compounds during Cabernet Sauvignon alcoholic fermentation and antioxidant properties of derived wines / Екстракциона кинетика на некои фенолни соединенија во текот на алкохолната ферментација на грозје од сортата каберне совињон и антиоксидантни својства на добиените вина
(The Society of Chemists and Techonogists of Macedonia, 2020)
In this study, we estimated the usage of Cabernet Sauvignon in microvinifications, obtaining wines with increased phenolic compound content. Kinetic extraction of phenolic compounds during alcoholic fermentation was affected ...
Phytochemical study of the genus amphoricarpos / Фитохемијско истраживање биљног рода Amphoricarpos
(Serbian Chemical Society, 2021)
Phytochemistry deals with the study of secondary metabolites produced by plants that synthesize these compounds for many reasons, including their own protection against attack of herbivores and plant diseases. Secondary ...
Assessment of hot-melt coating methods for multiparticulate substrates: Mortar-coating vs. pan-coating / Procena metoda za oblaganje višečestičnih supstrata topljenjem: oblaganje u pateni vs. oblaganje u bubnju
(Serbia : Pharmaceutical Association of Serbia, 2021)
Hot-melt coating (HMC) is an alternative, solvent-free coating method generally used to modify substrate release rate and/or mask its unpleasant taste. The aim of this study was to assess two HMC methods (pan-coating and ...
