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 ...
Analysis of inhibitory properties of Ce-citrate as a green corrosion inhibitor of low alloy steel in neutral chloride solution
(Wiley, 2022)
The new environmentally friendly corrosion inhibitor Ce-citrate was analyzed in 0.05 M NaCl solution on the AISI 4130 steel. For comparison, corrosion inhibitor Ce-chloride is tested in the same concentration as Ce-citrate ...
Analysis of the Ce(III) chloride, Ce(III) nitrate, and Ce(III) propionate as corrosion inhibitor of the aluminum alloys in NaCl solution
(Wiley, 2022)
Green corrosion inhibitors, Ce(III) chloride, Ce(III) nitrate, and Ce(III) propionate, were tested in NaCl solution with the aim to evaluate their inhibitory effect on 7049 aluminum alloy and to propose a mechanism of their ...
Heat transfer to a sphere immersed in a fluidized bed of coarse particles with transition from bubbling to turbulent flow regime
(Taylor & Francis, 2023)
The present work concerns an experimental study on heat transfer in gas-solid fluidized bed of coarse (Geldart D) particles to a larger immersed sphere at high superficial velocities from 2 to 5.5 Umf. The heat transfer ...
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 ...
Experimental examination and thermodynamic description of the ternary Bi-Ge-Ga,Zn systems
(Elsevier, 2020)
Due to the wide application of systems based on germanium ternary Bi-Ga-Ge and Bi-Ge-Zn systems were experimentally tested in this study. Used experimental techniques were scanning electron microscope with energy dispersive ...
The time response of plasmonic sensors due to binary adsorption: analytical versus numerical modeling
(Springer Nature, 2020)
In order to allow for multiscale modeling of complex systems we focus on various approaches to modeling binary adsorption. We consider multiple methods of modeling the temporal response of general plasmonic sensors. We ...
Thermodynamic Properties of Caffeine in Ethylene Glycol at High Pressures and High Temperatures
(USA : American Chemical Society, 2022)
Ethylene glycol is recognized as a heat transfer fluid. To improve its performance, caffeine is added to pure ethylene glycol. The experimental measurements of densities at pressures of up to 60 MPa and in the range of ...
Structural changes of waste biomass induced by alkaline treatment: the effect on crystallinity and thermal properties
(Springer Science and Business Media LLC, 2020)
A low-cost waste biomass generated from a food industry, apricot shells, was subjected to alkali modification in order to compare morphology, crystalline structure and thermal stability of native and modified biomass, ...
Sensitivity and fading of irradiated RADFETs with different gate voltages
(Elsevier, 2022)
The radiation-sensitive field-effect transistors (RADFETs) with an oxide thickness of 400 nm are irradiated with gate voltages of 2, 4 and 6 V, and without gate voltage. A detailed analysis of the mechanisms responsible ...
