Multi-wall carbon nanotubes (MWNTs) had been synthesized by catalytic chemical vapor deposition of acetylene over Fe loaded mesoporous silica. The as-grown MWNTs were purified by a two-step purification procedure involving acid washing and oxidation in diluted air, and characterized using powder X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), thermo...
The precursor Zn3N2 films were deposited on quartz glass substrates by reactive DC magnetron sputtering and oxidized in situ at various temperatures by introducing pure oxygen gas directly into the deposition chamber. X-ray diffraction (XRD), scanning electron microscopy (SEM), UVNIS transmittance, Hall-effect measurements and photoluminescence (PL) were carried out to investigate the structural,...
Cu/TiO2 composite nanoparticles were prepared by photoreduction deposition methods. The properties of the nanoparticles were widely characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) equipped with energy dispersive X-ray spectroscopy (EDS). Moreover, the antibacterial performances were performed by zone of inhibition (ZOI) tests against the bacteria species. The results...
The SrTiO3 and Y-doped SrTiO3 polycrystalline sintered bodies were synthesized by the polymerized complex (PC) process and the subsequent hot pressing at 1473 K for 1 h or at 1673 K for 2 h in Ar atmosphere. The X-ray diffraction patterns of the SrTiO3 and Sr0.9Y0.1TiO3 samples synthesized by the PC process and hot pressing at 1473 K showed that these samples were mostly composed of the SrTiO3 single...
In this paper, the processes associated with the electrodeposition of Selenium on Au substrates from nitric acidic solutions were investigated by combined electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV) measurements. The analyses reveal that H2SeO3 in the solution is firstly adsorbed on the surface of Au electrode during cathodic polarization and subsequently reduced to Se...
