The present study explores an environmentally friendly green approach to obtain cerium oxide nanoparticles via a biomediated route using Mellisa officinalis and Hypericum perforatum plant extracts as reducing agents. as-prepared were studied for their structural morphological characteristics XRD diffractometry, scanning electron microscopy, Raman, fluorescence electronic absorption spectra, X-ray photoelectron spectroscopy (XPS). pattern has shown the centered fluorite crystal structure of...
Polymer nanocomposite films based on poly(vinyl pyrrolidone) incorporated with different amounts of copper oxide (CuO) nanoparticles were prepared by the solution casting technique. The PVP/CuO nanocomposites analyzed X-ray diffractometry (XRD), scanning electron microscopy, UV-Visible absorption spectroscopy and dielectric spectroscopy. XRD analysis showed that monoclinic structure cupric was maintained in PVP host matrix. key optical parameters, such as energy gap E
The effects of electron beam irradiation on the properties ethylene propylene diene monomer (EPDM)/butyl rubber composites in presence a polyfunctional were investigated by means differential scanning calorimetry (DSC), thermal analysis, microscopy (SEM), attenuated total reflection absorption infrared spectroscopy (ATR-IR), and mechanical surface energy measurements. samples exposed over wide range doses (20⁻150 kGy). EPDM matrix was modified with butyl rubber, chlorobutyl bromobutyl...
Cerium oxide nanoparticles were prepared by a precipitation method using Ce(IV) sulphate as precursor dispersed in glycerol with varying synthesis parameters such temperature or precipitating agent. The structural and morphological characteristics of the obtained investigated X-ray diffraction, transmission electron microscopy, diffuse reflectance spectroscopy. crystallite size varied between 13 17 nm. presence Ce3+ Ce4+ was proved XPS data CeO2 samples conservation fluorite structure...
The equilibrium constants for complexation of C60 with poly(vinylpyrrolidone) (PVP) in water have been determined by UV−visible spectroscopy. magnitude the was found to describe formation a charge-transfer (CT) saturated 1:1 complex [PVP] = 2.62−5.25 × 10-2 M (K 1331.3 M-1), and contact-pairs 7.0−12.25 20.64 M-1). These results indicate that binding affinity drug receptors, base pairs double-stranded DNA, or AT-rich segments its minor groove form CT complexes is limited strong coordination...
Novel polythioetherimides bearing azobenzene moieties were synthesized from azobismaleimides and bis-2-mercaptoethylether. Kinetics of trans-cis photoisomerization thermal conversion cis to trans isomeric forms investigated in both polymer solution poly(methyl methacrylate) doped films using electronic absorption spectroscopy. Thermal recovery kinetics is well described by a two-exponential relation matrix, while that low molecular weight azobismaleimide fit first-order equation. The...
