Movement and velocity of a particle in an inverse fluidized bed
(Informa UK Limited, 2022)
The movement of particles in the fluidized bed primarily determines the mixing in the bed and determines the transfer intensities that occur between the particles and the fluid. Experimental monitoring of the velocity of ...
(Electro)chemical and antimicrobial characterization of novel Ru(II) bipyridine complexes with acetylpyridine analogs
(Informa UK Limited, 2022)
Three ruthenium-bipyridine complexes (1–3) carrying acetylpyridine ligand unit were synthesized in methanol via the reaction of [RuCl2(bpy)2] with corresponding acetylpyridine (2-, 3-, and 4-acpy). Obtained complexes were ...
Determination of lipophilicity and ionization of fentanyl and its 3‑substituted analogs by reversed-phase thin-layer chromatography
(Elsevier, 2022)
Lipophilicity and ionization constant of sixteen fentanyl analogues were investigated by reversed-phase thin-layer chromatography (RP-TLC). Fourteen compounds have nitrogen containing groups at C-3 position of the piperidine ...
TiO2/Bi2O3 coatings formed by plasma electrolytic oxidation of titanium for photocatalytic applications
(Springer, 2022)
TiO2 coatings modified by Bi2O3 particles were successfully formed by plasma electrolytic oxidation (PEO) process of titanium in supporting electrolyte (10 g/L Na3PO4·10H2O) with the addition of Bi2O3 particles. The ...
Thermal analysis and phase changes of mechanochemically activated sodium carbonate
(Elsevier, 2022)
Sodium carbonate is a well-known material for being used as a good sorbent of carbon dioxide from the atmosphere, and as such has gained increasing importance in environmental protection. In order to enhance its sorption ...
Interfacial charge transfer complex between TiO2 and non-aromatic ligand squaric acid
(Elsevier, 2022)
The attachment of squaric acid, a non-aromatic molecule, to the surface of TiO2 powder induced the optical absorption of the obtained hybrid material in the visible spectral range due to the interfacial charge transfer ...
Spatial–temporal assessment of hydrocarbon biodegradation mechanisms at a contaminated groundwater site in Serbia
(England: Taylor and Francis, 2022)
The characterization and cleanup of groundwater contamination in hazardous-waste sites are of significant engineering and scientific importance. This study analyzes biodegradation fingerprints in groundwater, 25 years after ...
Size-strain line-broadening analysis of anatase/brookite (TiO2)-based nanocomposites with carbon (C): XRPD and Raman spectroscopic analysis
(UK : International Union of Crystallography, 2022)
A size-strain line-broadening analysis of the XRPD patterns and Raman spectra for two anatase/brookite (TiO2)-based nanocomposites with carbon (C) was carried out and the results compared with those of a similar sample ...
Multiblock copolymers containing poly(butylene succinate) and poly(ε-caprolactone) blocks: Effect of block ratio and length on physical properties and biodegradability
(Springer, 2022)
In order to obtain polymers with preserved thermal properties and tunable biodegradability multiblock copolymers comprising blocks of biodegradable polyesters poly(ε-caprolactone) (PCL) and poly(butylene succinate) (PBS) ...
Aromaticity study of singlet- and triplet-state corannulene dianion and dication
(John Wiley and Sons Ltd, 2022)
Aromaticity rules in the ground singlet state and the first excited triplet state are exactly opposite, as shown by Baird. Thus, (4n + 2)π electron annulenes are antiaromatic and 4nπ annulenes are aromatic in their triplet ...
