Geochemical distribution of selected elements in flotation tailings and soils/sediments from the dam spill at the abandoned antimony mine Stolice, Serbia
(Springer Science and Business Media LLC, 2020)
Materials held within mine tailings pose a serious risk to the environment in cases of tailings dam failure. Collapse of the tailing dam at the Stolice antimony mine in West Serbia caused a spilling of tailing slurry into ...
Lead isotope ratios as tool for elucidation of chemical environment in a system of Macrolepiota procera (Scop.) Singer - soil
(Springer, 2020)
The analysis of isotope ratios of lead in the mushrooms and soil, where they were grown, assisted with a principal component analysis, offered a new perspective for understanding possible chemical environment in a real ...
Antioxidant Capacity of Dark Red Corn – Biochemical Properties Coupled with Electrochemical Evaluation
(Revista de Chimie, 2020)
Biochemistry coupled with electrochemical approach is employed in a fast, relatively simple, yet highly precise detection of a plant extract antioxidant properties. Antioxidant capacity of dark red corn grains was investigated ...
Influence of secondary phases in A356 MMCs on their mechanical properties at macro- and nanoscale
(Springer, 2020)
Metal matrix composites are very inhomogeneous materials, and their properties depend on various parameters (production process, constituents, their interfaces, etc.). The influence of SiC microparticles (40 mu m) reinforcement ...
Synthesis and pharmacological evaluation of novel cis and trans 3‑substituted anilidopiperidines
(Springer Nature, 2020)
Background 4-Anilidopiperidine class of synthetic opioid analgesics, with it’s representative fentanyl, are by far the most potent and clinically significant for the treatment of the severe chronic and surgical pain. ...
Evaluation of silver-incorporating zeolites as bifunctional electrocatalysts for direct borohydride fuel cells
(Royal Society of Chemistry, 2019)
Three zeolites (A, X and Y) with Ag incorporated in their cages are tested as bifunctional electrocatalysts
for direct borohydride fuel cells (DBFCs). Ag zeolites are characterised by XRD, FTIR, nitrogen sorption
and ...
Tailoring the electrochemical charge storage properties of carbonaceous support by redox properties of heteropoly acids: where does the synergy come from?
(Springer Science and Business Media LLC, 2019)
The synergistic effects between two Keggin-type heteropoly acids (HPAs) and carbon surface were examined and elucidated. An improved high rate capability (and potential high capacitor electrode for supercapacitors) of the ...
Electromagnetic simulation of MXene-based plasmonic metamaterials with enhanced optical absorption
(Springer, 2020)
In this contribution we propose, design and numerically analyze a plasmonic metamaterial for enhanced optical absorption, based on 100 nm thick titanium carbide (Ti3C2Tx) MXene sheets. The analyzed metamaterial is built ...

Semi‑rational design of cellobiose dehydrogenase for increased stability in the presence of peroxide
(Springer International Publishing, 2020)
Cellobiose dehydrogenase (CDH, EC 1.1.99.18) from white rot fungi Phanerochaete chrysosporium can be used for constructing biosensors and biofuel cells, for bleaching cotton in textile industry, and recently, the enzyme ...
