The aim of this study was to evaluate gold nanoparticles (AuNPs) for their anticancer activity against MCF-7 cancer cells, antioxidant activities and catalysis the reduction p-nitrophenol (p-NP). AuNPs were synthesized using kaempferol 3-O-β-D-apiofuranosyl-7-O-α-L-rhamnopyranoside (KG) from plant Lotus leguminosae. structure determined nuclear magnetic resonance (NMR) electrospray (ES)-HRMS. isolated compound involved in synthesis stabilization AuNPs. A number parameters such as pH mass...
Abstract BACKGROUND The increasing contamination of water bodies with industrial dyes necessitates efficient remediation strategies. CuO–ZnO composite nanoparticles (NPs) have shown promise as adsorbents due to their high surface area, stability, and tunable properties. This study focuses on optimizing the synthesis conditions CuO‐ZnO NPs via a co‐precipitation method evaluating performance for removal Reactive Black 5 (RB5) dye. RESULTS were synthesized varied precursor ratios, pH values,...
Highly crystalline CoFe2O4 nanoparticles with different diameters ranging from 2.4 to 6.1 nm have been synthesized by forced hydrolysis in polyol. The size can be controlled through adjusting the nominal water/metal molar ratio. X-ray diffraction, transmission electron microscopy, x-ray absorption spectroscopy and 57Fe Mössbauer spectrometry were employed investigate structure microstructure of particles produced. Magnetic measurements performed on these show that they are superparamagnetic...
The present research work reports an eco-friendly route for preparing gold nanoparticles (AuNPs) with high catalytic activity using polyphenol extracted from salvia officinalis. In both alkaline (pH ∼ 11) and acidic media 5), the induced rapid reduction of Au (III) salt lead to formation highly monodisperse spherical small (S) larger (L) AuNPs, respectively. average particle size was found be 6 nm S 27 L FT-IR revealed that species are capped onto surface favorizing a aqueous colloidal...
An optimization study for the sol-gel synthesis of Ni0.5Zn0.5Fe2O4 nanoparticles and their performance adsorptive removal methylene blue (MB) dye was reported. The as-produced samples associated calcined corresponding ones in range 400–800 °C were systematically characterized structure microstructure using different techniques. For expected best candidate MB removal, pure NiZn nanoferrite (optimized parameters: Fuel=Urea; pH=5; [Fe3+]:0.025 M; Total nitrate to fuel molar ratio=8/6.66)...
We examined the effects of iron oxide nanoparticles (IONPs) on mitochondrial respiratory chain complexes activities and coupling in young (3 months) middle-aged (18 rat liver, organ largely involved body detoxification. Isolated liver mitochondria were extracted using differential centrifugations. Maximal oxidative capacities (V(max), I, III, IV activities), V(succ) (complexes II, V tmpd, (complex activity), together with (V(max)/V0) determined controls conditions after exposure to 250, 300,...
In the present research work, we report co-precipitation synthesis of size‐controlled uncoated (Magn) and natural chalcone dye-functionalized superparamagnetic magnetite nanoparticles (Magn_NCD NPs) study their efficiency for adsorption methylene blue (MB) as well antibacterial activity. The NCD was isolated from Acacia cyanophylla characterized by using IR, UV-visible 1H NMR spectroscopies. For functionalized NPs, size-control achieved varying pH (pH5 sample Magn_NCD5 pH8 Magn_NCD8)...
This study examines the solubility of benzamide (BZA), correlating with theoretical models and calculating thermodynamic property parameters. In this work, gravimetric method was utilized to determine in three individual solvents (methanol, ethanol, 1-propanol, ethyl acetate), as well (ethanol + acetate) (methanol (1-propanol binary mixed solvents. The results demonstrated that increased first then decreased increasing mole fractions methanol/ethyl acetate ethanol/ethyl at same temperature....
The present work reports the influence of nanoadditives Y2O3, Gd2O3, and CaO on magnetic, electrical dielectric properties sintered nanoferrites Co0.2Ni0.3Zn0.5Fe2O4. All powders were synthesized via polyol method. XRD analysis showed that except nanoferrite which was obtained by in an one-post procedure, subsequent calcinations as-produced additives necessary to obtain nanocrystals desired phases. mean particle size inferred from TEM images at 1000 °C ranges 87 nm for Y2O3 126 CaO.
