Geochemical Fractionation and Assessment of Probabilistic Ecological Risk of Potential Toxic Elements in Sediments Using Monte Carlo Simulations
(MDPI, 2019)
The need for further research into potentially toxic elements in Serbian rivers led to an
investigation of distributions, sources, and ecological risks in a sample base of sediments from
15 rivers. The analyses were ...
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 ...
Peroxidase-Sensitive Tyramine Carboxymethyl Xylan Hydrogels for Enzyme Encapsulation
(Springer, 2019)
Derivatives of xylans were synthesized from corncob xylan by carboxymethylation, oxidization with different molar ratios of periodate (5, 10 15 and 20 mol%) and by reductive amination with tyramine. Modifications of tyramine ...
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 ...
Synthesis and preliminary screening for the biological activity of some steroidal Δ4-unsaturated semicarbazone derivatives
(Elsevier, 2019)
Eleven new steroidal mono- and bis(semicarbazones) 2a–e, 4d and 3a–e have been prepared starting from various 3-oxo-α,β-unsaturated steroids. Mono-semicarbazones 2a–e were further subjected to ethyl chloroacetate in boiling ...
Pollution and health risk assessments of potentially toxic elements in soil and sediment samples in a petrochemical industry and surrounding area
(MDPI, 2019)
The pollution state and health risk assessment of potentially toxic elements (PTE) in soil and sediment samples of the petrochemical industry and its surrounding area are evaluated in this study. The pseudo-total contents ...
A comprehensive study of conditions of the biodegradation of a plastic additive 2,6-di-tertbutylphenol and proteomic changes in the degrader Pseudomonas aeruginosa san ai
(Royal Society of Chemistry, 2019)
The Pseudomonas aeruginosa san ai strain was investigated for its capability to degrade the 2,6-di-tertbutylphenol (2,6-DTBP) plastic additive, a hazardous and toxic substance for aquatic life. This
investigation was ...
Complexes of Zn(II)–Triazoles with CO2 and H2O: Structures, Energetics, and Applications
(American Chemical Society (ACS), 2019)
Using a first-principle methodology, we investigate the stable structures of the nonreactive and reactive clusters formed between Zn2+–triazoles ([Zn2+-Tz]) clusters and CO2 and/or H2O. In sum, we characterized two modes ...
