The thermophysical properties and thermal performance of water- and ethylene-glycol-based nanofluids containing and CuO nanoparticles were examined. Nanofluids were prepared at four concentrations (1- 4 vol%) using an electric mixer and magnetic stirrer, and the thermophysical properties were measured. Surfactants were used to improve stability. The transient hot-wire method (KD2-Pro device), Dynamic Light Scattering (DLS), […]
In this work, PP+CdS/ZnS transparent hybrid polymer nanocomposites were synthesized and studied. The nanocomposites were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive (EDS), and UV-spectroscopy analysis. It was found that the bandgap of PP+1%CdS/ZnS; PP+3%CdS/ZnS, and PP+5%CdS/ZnS; PP+10%CdS/ZnS nanocomposites is 5.2 eV, 5.1 eV, 4.6 eV, respectively. SEM analysis showed that […]
In this paper, MgAl2O4 nanoparticles were synthesized by the Sol-gel auto combustion method and were doped with different concentrations of Ni2+ (x= 0, 0.1, 0.05, and 0.03). By this method, a novel photocatalyst which had better decolorization percentages of Congo redcompared to MgAl2O4 was produced. The MgAl2O4 samples were calcinated at 1000 0C. The samples […]
In the last decade, the bio-assisted synthesis of nanoparticles has been significantly exploited seeing the shortfall of chemical synthesis and urgent need to find the substitution. The chemical synthesis of nanoparticles is a rapid process, which might be appealing in various frontiers but has got some serious issues to take care of. In pursuit of […]
Bismuth tungstate (Bi2WO6) emerged as one of the most capable chromogenic compounds among transition metal oxide having wide opto-electronic applications. It is an n-type semiconducting material having bandgap around ~2.7eV. Conversely, NanoComposite (NC) materials have been investigated in order to tailor the properties polymers and also to widen the applications. In this context Poly (vinyl […]
Bioactive glass is an appropriate substance for the transporting a pharmaceutical compound owing to its special effects (containing great antibacterial, semiconducting, nanoporous, adherent, and strong bonding with the bone tissue). Hence, in recent years, many investigations have been done in this topic. However, several constraints alike fast drug release and slow drug loading ability are […]
