Anaphoretical/oxidative approach to the in-situ synthesis of adherent hydroxyapatite/titanium oxide composite coatings on titanium
(Elsevier, 2019)
In-situ synthesis of HAp/TiO2 coating on titanium was performed via anaphoretic deposition of HAp and simultaneous anodization of Ti to produce highly adherent and strengthened composite coating. The prepared coatings were ...
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 ...
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 ...
N-benzyl derivatives of long-chained 4-Amino-7-chloro-quionolines as inhibitors of pyocyanin production in Pseudomonas aeruginosa
(American Chemical Society (ACS), 2019)
Pseudomonas aeruginosa is a leading cause of nosocomial infections that are becoming increasingly difficult to treat due to the occurrence of antibiotic resistant strains. Since P. aeruginosa virulence is controlled through ...
Structural and electrochemical properties of the Li2FeP2O7/C composite prepared using soluble methylcellulose
(Elsevier, 2019)
A new method involving the homogeneous dispersion of precursor compounds inside a methylcellulose matrix is used for the synthesis of a composite powder of Li 2 FeP 2 O 7 and carbon. The properties of carbon-containing and ...
Enantioselective Organocatalytic Enamine C−H Oxidation/Diels‐ Alder Reaction
(Wiley, 2019)
α,β‐unsaturated aldehydes have been traditionally used in LUMO lowering asymmetric aminocatalysis (iminium catalysis), while the use of saturated aldehydes as substrates in this type of catalysis has been elusive, until ...
Evaluation of heavy metals and radionuclides in fish and seafood products
(Elsevier, 2019)
Despite the existence of a legislation regarding food contaminants, food safety control in Serbia is a matter of great concern. This study investigates the radioactivity levels and heavy metal concentrations in fish and ...
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 ...
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 ...
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 ...
