Mechanically-robust nanocomposite membranes have been developed via crosslinking chemistry and electrospinning technique based on the rational selection of dispersed phase materials with high Young's modulus (i.e., graphene multiwalled carbon nanotubes) Cassie-Baxter design used for oil water separation. Proper can enhance stiffness fiber while their length has to be larger than critical length. Chemical modification fluorochemcials induced roughness were achieve superhydrophobocity. Surface...
The essential oil derived from Citrus plants has long been used for medicinal purposes, due to its broad spectrum of therapeutic characteristics. To date, approximately 162 species have identified, and many investigational studies conducted explore the pharmacological potential spp. oils. This study investigated volatile constituents distilled leaves C. hystrix, limon, pyriformis, microcarpa, using gas chromatography-quadrupole mass spectrometry. A total 80 secondary compounds were...
Abstract Targeting reactive oxygen species (ROS) while maintaining cellular redox signaling is crucial in the development of medicine as origin several prevailing diseases including chronic kidney disease (CKD) linked to ROS imbalance and associated mitochondrial dysfunction. Here, we have shown that a potential nanomedicine comprising Mn 3 O 4 nanoparticles duly functionalized with biocompatible ligand citrate (C-Mn NPs) can maintain balance an animal model oxidative injury. We developed...
Excess consumption of fluoride (F–) through drinking water and its detrimental effects on human health have been a serious global concern. Herein, we developed facile highly sensitive spectroscopic technique for selective detection F– in aqueous media using aluminum phthalocyanine chloride (AlPc-Cl) as sensor. The absorbance steady-state fluorescence intensity AlPc-Cl has found to decrease the presence which used marker determination concentration water. structural change after addition...
A simple sample preparation method based on a modified liquid-phase extraction approach to extract selected pharmaceuticals and personal care products from freshwater organisms is described. Extracted samples were analysed using liquid chromatography with Q-Exactive plus hybrid quadrupole Orbitrap mass spectrometry, 2.6 μm C18 media. 0.1% v/v acetic acid/acetonitrile mobile phase was applied over 20 min gradient. Method detection limits in full scan mode ca. 0.04-2.38 ng of analyte per g...
Electrochemical determination of dopamine (DA) in the presence a large excess ascorbic acid (AA) their coexistence at nickel oxide nanoparticle-modified preoxidized glassy carbon electrode (GC ox /nano-NiO x ) is achieved. The GC prepared by electrodeposition nanoparticles (nano-Ni) onto an electrochemically activated (GC) electrode, and thus nano-Ni were subjected to electrochemical oxidation alkaline medium for formation (NiO ). Modified electrodes morphologically characterized. effect...
Background: Sertraline (ST) hydrochloride is an anti-depressant of the selective serotonin reuptake inhibitor (SSRI) class. Potentiometric sensors are appealing route for detecting drugs due to some advantages in terms sensitivity, feasibility, selectivity, fast response, tolerance turbidity and colour solutions, cost-effectiveness. Methods: A mixture polyvinyl chloride powder (PVC) with o-nitrophenyl octyl ether ion association complex was dissolved tetrahydrofuran (THF) prepare membrane...
The present study introduced the construction and electroanalytical characterization of novel tirofiban (TIR) carbon paste voltammetric sensors integrated with copper oxide nanoparticles. nanostructure remarkably enhanced oxidation TIR molecules on electrode surface an irreversible anodic peak at about 1.18 V. current values recorded differential pulse voltammograms were correlated to concentrations within a defined linear range from 0.060 7.41 μg mL–1 LOD value 20.7 ng mL–1. Based...
This study evaluates the applicability of enantioselective gas chromatography (eGC) and comprehensive two-dimensional (eGC×GC) coupled with flame ionization detection for stereospecific analysis designated chiral monoterpenes within essential oils distilled from leaves Citrus hystrix (CH), C. limon (CL), pyriformis (CP), microcarpa (CM). A cryogen-free solid-state modulator a combination first-dimension polar second-dimension column arrangements was used to resolve potential interferences in...
The electrochemical energy storage that based on earth-abundant materials is essential because of the future demands. Because carbon-based architecture supercapacitors, rapid charging/discharging, and long life cycle, they considered attractive compared to chemical batteries. Therefore, copper oxide (CuO) as positive electrode reduced grapheme (rGO) negative were used for a high-performance supercapacitor in low cost, simple, ecofriendly method. During present work, synthesized graphene...
This study involves the preparation and investigation of a novel highly selective poly(vinyl chloride)-based membrane 2-((5-(2-hydroxy-3-methoxybenzylideneamino)-2H-1,2,4-triazol-3-ylimino)methyl)-6-methoxyphenol Schiff base ligand (HMBT), which is neutral ionophore with sodium tetraphenyl borate (STB) in form an excluder o-nitrophenyloctyl ether (o-NPOE) solvent mediators (plasticizing) as Ni(II)-selective electrode. The observation optimal performance was done wherein shown to have...
