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 ...
The study of composition-properties relationships for composite hydrogels based on poly(methacrylic acid) and high concentrations of MFI zeolite
(Elsevier, 2023)
High concentrations of hydrophobic MFI zeolite (26.0–51.3 wt%) were successfully embedded in poly(methacrylic acid) (PMAA) network in simple, one-pot synthesis of PMAA-MFI composite hydrogels. The effects of zeolite ...
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 ...
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, 2024)
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. ...

(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 ...
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 ...
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, ...
Unravelling conformational and crystal packing preferences of cyclohexane-5-spirohydantoin derivatives incorporating a halogenated benzoyl group
(Royal Society of Chemistry, 2022)
Two spirohydantoin derivatives, 3-(4-chlorobenzoyl)-1,3-diazaspiro[4.5]decane-2,4-dione (1) and 3-(4-bromobenzoyl)-1,3-diazaspiro[4.5]decane-2,4-dione (2), were synthesized and analyzed by single crystal X-ray diffraction, ...
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 ...
