In this work, cloud point extraction (CPE) technique was developed for the separation and pre-concentration of Cd(II). CPE used with lipophilic hexadentate (N4O2) Schiff base ligand, L22pysa (1, C24H26N4O2). The methodology is based upon formation a Cd(II)/L complex soluble in micellar phase non-ionic surfactant Triton X-114. This then extracted into surfactant-rich above its temperature. Several important variables that affect were investigated optimized. Under optimum experimental...
This article aims to provide a survey of biological applications Schiff base macrocycles and their metal complexes, with emphasis given the synthesis compounds uses as antibacterial antifungal agents. The literature on subject, published during 2005–2019 period, is shortly reviewed. an informed report collecting information addressed topic in concise systematic way, can be expected useful fast catalogue for researchers working this related domains.
Abstract In this study, a commercial dental resin was reinforced by SiO 2 nanoparticles (NPs) with different concentrations to enhance its mechanical functionality. The material characterization and finite element analysis (FEA) have been performed evaluate the properties. Wedge indentation 3-point bending tests were conducted assess behavior of prepared nanocomposites. results revealed that optimal content NPs achieved at 1% , resulting in 35% increase reaction force. Therefore, sample...
The possible interaction between the antiviral drug oseltamivir and calf thymus DNA at physiological pH was studied by spectrophotometry, competitive spectrofluorimetry, differential pulse voltammogram (DPV), circular dichroism spectroscopy (CD), viscosity measurements, salt effect, computational studies. Intercalation of base pairs shown a sharp increase in specific decrease peak current positive shift voltammogram. Competitive fluorescence experiments were performed using neutral red (NR)...
Two new potentially hexadentate Schiff bases, [H2L1] and [H2L2], were prepared by condensation of 2-(3-(2-aminophenoxy)naphthalen-2-yloxy)benzenamine with 3,5-di-tert-butyl-2-hydroxy benzaldehyde o-vanillin, respectively. Reaction these ligands cobalt(II) chloride, copper(II) perchlorate, zinc(II) nitrate gave complexes ML. The their have been characterized a variety physico-chemical techniques. solid solution state investigations show that the are neutral. Molecular structures [CuL1],...
Polycarbonate (PC)-ZnO films with different percentages of ZnO were prepared by a solution stirring technique and subjected to ultraviolet (UV; λ = 254 nm) irradiation. Structural parameters the samples effects UV irradiation on surface properties PC PC-ZnO nanocomposites evaluated X-ray diffraction (XRD), photoelectron spectroscopy (XPS), atomic force microscopy (AFM), water contact angle (WCA) measurements, Vickers microhardness (HV) tester. The XRD patterns nanocomposite found show an...
