New copper (II) complexes derived from azo pyridone dyes: Structure characterization, thermal properties, and molecular docking studies
(John Wiley and Sons Ltd., 2023)
Two azo dye ligands, bearing different substituents (chlorine atom or methoxy group) in the para-position of the phenyl ring, were employed for the synthesis of two Cu(II) chelates. Full structural affirmation of complexes ...
Dispersive Solid–Liquid Microextraction Based on the Poly(HDDA)/Graphene Sorbent Followed by ICP-MS for the Determination of Rare Earth Elements in Coal Fly Ash Leachate
(MDPI, 2022)
A dispersive solid-phase microextraction (DSPME) sorbent consisting of poly(1,6-hexanedi-ol diacrylate)-based polymer microspheres, with embedded graphene microparticles (poly(HDDA)/g-raphene), was synthesized by microfluidic ...
Novel Biocomposite Films Based on High Methoxyl Pectin Reinforced with Zeolite Y for Food Packaging Applications
(Foods, 2022)
Pectin is a natural biopolymer with broad applications in the food industry and it is suitable to prepare edible films to prolong food shelf-life. However, the main limitation of pectin-based films is their poor mechanical ...
Effects of the silver nanodots on the photocatalytic activity of mixed-phase TiO2
(Journal of the American Ceramic Society, 2022)
We present the synthesis and photocatalytic properties of mixed-phase TiO2 nanoparticles decorated with silver nanodots obtained by environmental-friendly wet chemical method using low molecular weight chitosan as the ...
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 ...
Recovery of bioactive molecules from Hypericum perforatum L. dust using microwave-assisted extraction
