A simulation of free radicals induced oxidation of dopamine in aqueous solution
(Elsevier, 2019)
Understanding the basic chemistry between highly reactive free radicals and dopamine is an important step in characterizing the antioxidative activity of catecholamine neurotransmitters. In this work, we simulated the ...
Characterization and electrochemical properties of organomodified and corresponding derived carbonized clay
(Oxford : Pergamon-Elsevier Science Ltd, 2019)
Series of alkylammonium modified smectites with different alkylammoinum/clay ratios was synthesized (H series). The obtained organoclays were used as precursors for carbon-clay composite materials (C series). Both set of ...
The influence of low-frequency magnetic field regions on the Saccharomyces cerevisiae respiration and growth
(Elsevier, 2019)
The influence of four low-frequency magnetic field (MF) ranges 10–300 Hz, 10–100 Hz, 10–50 Hz and 50–100 Hz in scanning regime (all frequencies from selected range were scanned during 100 s repetitively during 24 h) on ...
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 ...
Mechanism of formation of the honeycomb-like structures by the regime of the reversing current (RC) in the second range
(Elsevier, 2019)
Electrodeposition of copper in the hydrogen co-deposition range by the regime of reversing current (RC) in the second range has been investigated by determination of the average current efficiency for hydrogen evolution ...
Integrating surface plasmon resonance and slow photon effects in nanoporous anodic alumina photonic crystals for photocatalysis
(Royal Society of Chemistry (RSC), 2019)
This study explores the potential of gold-coated titania-functionalized nanoporous anodic alumina distributed Bragg reflectors (Au-TiO2-NAA-DBRs) as platforms to enhance photocatalytic reactions by integrating “slow photons” ...
Comparative morphological and crystallographic analysis of copper powders obtained under different electrolysis conditions
(Elsevier, 2019)
Production of copper powders by the potentiostatic electrolysis under different hydrogen evolution conditions was investigated. Copper powders were characterized by the scanning electron microscope (SEM), X-ray diffraction ...
Production of levan by Bacillus licheniformis NS032 in sugar beet molasses-based medium
(Elsevier, 2019)
The production of levan by Bacillus licheniformis NS032 in a medium based on sugar beet molasses was studied. High polysaccharide yields were produced by using diluted molasses (100-140 g/L of total sugars) with the addition ...
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 ...
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 fortheir furanocoumarin content antioxidant potential and acetylcholinesterase and α-amylase inhibitory activities. ...
