Oscillatory Carbonylation of Poly(Ethylene Glycol)Methyl Ether Acetylene. Modelling of Reaction Mechanism and Stoichiometric Network Stability Analysis
(University of Kragujevac, 2019)
The reaction mechanism of palladium-catalysed oscillatory carbonylation of
poly(ethylene glycol)methyl ether acetylene (PEGA) was examined by stoichiometric
network analysis (SNA) of the stability of the dynamic states. ...
Furanocoumarin Content, Antioxidant Activity, and Inhibitory Potential of Heracleum verticillatum, Heracleum sibiricum, Heracleum angustisectum, and Heracleum ternatum Extracts against Enzymes Involved in Alzheimer’s Disease and Type II Diabetes
(Willey, 2019)
Hexane extracts of Heracleum verticillatum, H. sibiricum, H. angustisectum, and H. ternatum were studied for their furanocoumarin content antioxidant potential and acetylcholinesterase and α-amylase inhibitory activities. ...
Investigation of ZnFe2O4 spinel ferrite nanocrystalline screen‐printed thick films for application in humidity sensing
(John Wiley & Sons, Inc., 2019)
Zinc ferrite nanocrystalline powder was obtained by solid state synthesis of starting zinc oxide and hematite nanopowders. Field emission scanning electron microscopy (FESEM and transmission electron microscopy (TEM), X‐ray ...
Superior cellulolytic activity of Trichoderma guizhouense on raw wheat straw
(Springer Science and Business Media LLC, 2019)
Lignocellulosic plant biomass is the world’s most abundant carbon source and has consequently attracted attention as a renewable resource for production of biofuels and commodity chemicals that could replace fossil resources. ...
Experimental Examination and Thermodynamic Description of the Ternary Bi-Ge-In and -Sn Systems
(Springer Science and Business Media LLC, 2019)
In the present study, ternary Bi-Ge-In and Bi-Ge-Sn systems were experimentally investigated using differential thermal analysis (DTA), scanning electron microscopy with energy dispersive spectroscopy (SEM–EDS) and x-ray ...
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 ...
Half-sandwich ruthenium(II)-arene complexes: synthesis, spectroscopic studies, biological properties, and molecular modeling
(Taylor & Francis, 2019)
In search for antitumor metal-based drugs that would mitigate the severe side-effects of cisplatin, Ru(II) complexes are gaining increasing recent interest. In this work, we report on the synthesis, characterization (1H- ...
Periphyton development during summer stratification in the presence of a metalimnetic bloom of Planktothrix rubescens
(Elsevier, 2019)
Cyanobacterial blooms have become common all over the world, negatively affecting various ecosystem components. Planktothrix rubescens is a planktonic cyanobacterium that frequently causes blooms in temperate (mostly ...
Grape Seed Polyphenols and Fatty Acids of Autochthonous Prokupac Vine Variety from Serbia
(Wiley, 2019)
Grape pomace (grape skin, seeds, and stems) represents a valuable source of bioactive compounds, thus the interest in making use of these wine waste products is increasing. Prokupac is an autochthonous Serbian variety of ...
