In this paper, we report a new method to prepare the polymer/inorganic nanoparticle composites using electron irradiation-induced polymerization. The mixture of nanoparticles and MMA solution were co-irradiated by 1.6 MeV electron beam to a dose of 10, 20 and 30 kGy at a dose-rate of 60 kGy/h in air at room temperature. The products after irradiation were extracted using a soxhlet extractor wit...

A lignocellulose/montmorillonite (LMT) nanocomposite was prepared as a reusable adsorbent for cobalt(II) ions, and characterized by nitrogen (N₂) adsorption/desorption isotherm, X-ray Diffraction (XRD), Scanning Electron Microscope (SEM), Transmission Electron Microscopy (TEM), and Fourier Transform Infrared Spectroscopy (FTIR). LMT exhibited efficient adsorption of cobalt ions (Co(II)), and th...

biocl microflowers were synthesized using bismuth nitrate pentahydrate and sodium chloride by microwave (mw) assisted synthesis method for 23 minutes at 180 w. scanning electron microscopy (sem) studies revealed a unique morphology of flower-like assemblies comprised of nanosheets. the x-ray diffraction (xrd) pattern showed that a highly pure and crystalline phase has been obtained. the energy ...

the purpose of the present study was to synthesize and characterize nanosilica from alkali-extraction of silica fume under controlled conditions using poly (vinyl alcohol) (pva) as a dispersing agent. the dissolution efficiency of silica fume was affected by various factors such as concentration of the reagent, reaction time and temperature. a maximum dissolution efficiency of 91% was achieved ...

V2O5/SiO2 nanoparticles was prepared via an one-pot sol gel method from vanadyl- acetylacetonate and tetraethylorthosilicate in refluxing MeOH, followed by calcination at 700 °C for 2 hours. The resultant nanoparticles was characterized by means of scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), TGA and FTIR techniques. Rapid and efficient ar...
