New optimality criteria for convex continuous-time problems of vector optimization
(Optimization, 2022)
In this paper, vector continuous-time programming problems with inequality type of constraints are considered. All the results are obtained under convexity assumptions. The main tool employed in the derivation of the zero ...
Introducing the azocinnamic acid scaffold into bent-core liquid crystal design: A structure–property relationship study
(Elsevier B.V., 2022)
A series of bent-core liquid crystals possessing the azocinnamoyl unit in both elongating side arms was synthesized. The chain length was kept fixed for each molecule (C12H25), whereas the substituents at the central and ...
Flame-Retardant, Antimicrobial, and UV-Protective Lignin-Based Multilayer Nanocoating
(American Chemical Society, 2022)
Creating multifunctional textiles using chemicals from renewable sources is challenging. In an effort to develop a sustainable and efficient multifunctional cotton treatment, a lignin-based multilayer nanocoating comprising ...
Isopiestic determination of osmotic coefficients in the ionic strength range Im = (0.9670–2.2160) mol⋅kg−1 and activity coefficients determined by electromotive force measurements in the range Im = (0.0897–1.0054) mol⋅kg−1 of the {yKCl + (1 – y) K2HPO4}(aq) system at T = 298.15 K
(Elsevier B.V., 2022)
The mean activity coefficients of KCl in the ternary system {y KCl + (1 – y) K2HPO4}(aq) were experimentally determined at T = (298.15 ± 0.01) K by the electromotive force measurement (EMF method) using the cell of the ...
Influence of chloride ion concentration on initial corrosion of AZ63 magnesium alloy
(Nonferrous Metals Society of China, 2022)
The initial corrosion behavior of AZ63 magnesium alloy was investigated in 1, 3, 5 and 7 wt.% NaCl solutions by means of corrosion potential, linear polarization, electrochemical impedance spectroscopy, and polarization ...
The overlooked potential of raspberry canes: from waste to an efficient low-cost biosorbent for Cr(VI) ions
(Springer Science and Business Media Deutschland GmbH, 2022)
Screening of various potential biosorbents originated from locally available lignocellulosic biomass has led to the investigation of so far uninvestigated raspberry cane for removal of Cr(VI) ions from aqueous solutions. ...
Supercritical CO2-assisted processes for development of added-value materials: Optimization of starch aerogels preparation and hemp seed extracts impregnation
(Elsevier Ltd, 2022)
The aim of the present study was the utilization of supercritical CO2 as a green medium in various processes: starch gel drying, supercritical extraction from hemp seed flour (SCE process), hemp seed oil (HSO) impregnation ...
Challenges in determining the electrochemically active surface area of Ni-oxides in the oxygen evolution reaction
(Elsevier B.V., 2022)
Thin films of Ni-oxy-hydroxides of different composition and thickness were electrochemically grown on Ni foil electrode: hydrated α-phase, anhydrous β-phase, and two mixed α- and β-phase electrodeposited by potential ...
Morphological assessment of cavitation caused damage of cordierite and zircon based materials using principal component analysis
(Elsevier Ltd, 2023)
The pattern recognition approach, explored by this study, applies the principal component analysis (PCA) as the most widely used statistical method with the aim of assessing the initiation and propagation of the cracks and ...
Green manufacturing of high-value extracts from milk thistle seeds: Parameters that affect the supercritical CO2extraction process
(Elsevier Ltd, 2022)
The aim of this study was to provide insights into parameters that affect the oil extraction from an industrially valuable raw material (milk thistle) using green solvent supercritical CO2. The effect of plant origin, ...
