Bisaurones-enzymatic production and biological evaluation
(Royal Society of Chemistry, 2020)
The Trametes versicolor laccase catalyzed oxidation of chalcone butein afforded four dimers of aurone sulfuretin (i.e. two regioisomeric pairs of diasteromers, 1-4) as the major products. The formation of the dimers was ...
Varietal differences of Prokupac, Evita and Čokot Zemun based on their anthocyanins content in grape skin extract
(Chemistry & Biodiversity, 2021)
In this study we have analyzed the anthocyanin composition of skin extracts of three red grape varieties Prokupac, Evita and Čokot Zemun in order to distinguish these cultivars based on their anthocyanin profile. Also, ...
Element Content in Volcano Ash, Soil and River Sediments of the Watershed in the Volcanic Area of South Iceland and Assessment of Their Mobility Potential
(MDPI, 2021)
In this work, we present the results of element content in river sediments and soil of the Rangárvellir river in southern Iceland as well as in the volcano ash from the Eyjafjallajökull eruption in 2010. Severe natural ...
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 ...
Soil erodibility in European mountain beech forests
(Canadian Science Publishing, 2021)
Forests in Europe are currently not endangered by soil erosion. However, this can change with climate change orwith intensified forest management practices. Using a newly established network of plots in beech forests across ...
Biotransformation of Perrottetin F by Aspergillus niger: New Bioactive Secondary Metabolites
(Türkiye : ACG Publications, 2021)
Biotransformation of bis-bibenzyl perrottetin F (1), isolated from the liverwort Lunularia cruciata by Aspergillus niger, has been investigated. New metabolites (2-4) have been isolated using reversed phase semipreparative ...
Corrosion behaviour of AA2024 aluminium alloy in different tempers in NaCl solution and with the CeCl3 corrosion inhibitor
(Wiley - VCH Verlag GmbH & Co, 2020)
The paper analyses the corrosion behaviour of naturally and artificially aged
AA2024 alloy in NaCl solution and in the presence of an environment ‐ friendly
corrosion inhibitor, CeCl 3 . On the basis of the values of ...
Antioxidant Capacity and Quality of Human Milk and Infant Formula Determined by Direct Current Polarography
(Springer, 2021)
Antioxidants present in infant food contribute to its nutritive value and provide protection from oxidative damage. Here, a direct current polarographic method, based on a decrease of anodic current from the hydroxoperhy ...
Anodizing/Anaphoretic Electrodeposition of Nano-Calcium Phosphate/Chitosan Lactate Multifunctional Coatings on Titanium with Advanced Corrosion Resistance, Bioactivity, and Antibacterial Properties
(American Chemical Society (ACS), 2021)
The aim of this work was to investigate corrosion resistivity, bioactivity, and antibacterial activity of novel nano-amorphous calcium phosphate (ACP) potentially multifunctional composite coatings with and without chitosan ...
Ruthenium containing perovskites as electrode materials for 4-nitrophenol detection
(Elsevier, 2021)
In this paper, the relationship of structure, type of oxygen defects, valence states of Cr and Ru, and electro-
chemical properties of La0.7Sr0.3Cr1-XRuXO3 (0 < x < 0.1) perovskite-type oxides were studied. The samples ...
