Pb(Zr0.52Ti0.48)O3 (PZT) nanotubes with diameters of 80–100 nm and a wall thickness of 15–20 nm were prepared by sol–gel template technique and using multi-walled carbon nanotubes (MWCNT) as sacrificial templates. The coating process of MWCNT with PZT precursor sol and removal of the carbon nanotubes by an interrupt heat treatment were discussed and studied by Raman spectroscopy. Simultaneous t...

Polyimide/Nickel oxide (polyimide/NiO) nanocomposite was successfully synthesized by sol gel technique, using Pyromellitic dianhydriede (PMDA), 4,4-oxydianiline (ODA) and N,N-dimethylacetamide (DMAC) and 10 wt% Nickel titanate nanopowders (NPs). Fourier transform infrared spectrometry (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), and vibrating sample magnetometer (VSM) we...

in this paper, a modified sol-gel method using peroxotitanic acid sol (pta) was applied for the preparation of tio2 nanostructured thin films on glass plates. the peroxotitanic acid sol was synthesized using titanium isopropoxide, isopropylalchol, h2o and hydrogen peroxide. tio2 films were then calcined at 500oc and characterized by x-ray diffraction (xrd) and scanning electron microscopy (sem)...

we report on the synthesis, morphology, chemically and structurally of tio2-cuo-sio2 nanostructure with different precursors molar ratio and calcined temperatures. in the present work, ternary reactive powders in the tio2-cuo-sio2 systems have been obtained using the sol-gel method, by the simultaneous gelation of all cations. the compounds and other elements change in special chemical and phys...

The ZnO sol well-crystallized was prepared by the sol-gel method. The ZnO films were coated on medical-grade PVC surface by the improved organic-inorganic interfacial adhesion method. The physical and photocatalytic properties of the samples were characterized by XRD, SEM, DRS spectra and measured by the photodegradation reaction of Rhodamine B (RhB) and anti-bacteria for Escherichia coli (E. c...

Nickel oxide thin film of various preferred orientations was deposited using sol-gel method using solvents including methanol. The resulting film was analyzed using X-ray diffraction (XRD), scanning electron microscopy (SEM), contact angle measurement, and ultraviolet spectroscopy (UV-vis). Antibacterial activities of nickel oxide-based film against gram-negative bacteria (Escherichia coli) has...

incorporation of copper species into silica matrix was performed by the sol-gel method. copper ions and copper particles were doped using two different copper sources; cu(no3)2.3h2o and copper particles chemically synthesized.the particles of copper metallic, cuprous and cupric oxide were prepared and the synthesis and characterizations of copper species were compared together. on the other han...

ZnO/SiO2 was prepared using sol-gel method, and vanadium particles were loaded on this nano-photocatalyst by wet incipient method. They characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive (EDX) analysis andFouriertransform infrared spectroscopy (FT-IR). The XRD patterns showed that the zinc oxide samples have a wurtzite structure and vanadium dope...
