The Fe nanowires were prepared by Ac electrodeposition method. The two steps anodized aluminum oxides (alumina) were used as templates for electrodeposition of magnetic nanowires. Sulfuric acid was used to anodize aluminum. The pours diameter and growth rate of alumina were investigated. The FeSO4 electrolyte was used for growth of nanowires. The prepared magnetic nanowires were characterized b...

Multiwalled carbon nanotubes (MWCNTs) have a great potential in wide applications but faces limitation in term of dispersion feasibility. The aggregation of MWCNTs floss has restricted its usage and thus, acid treatment is expected to promote the MWCNTs reaggregation. The functionalization process of MWCNTs involves oxidation reaction using mild aqueous acid mixture of HNO3 and H2SO4 (1:3 v/v),...

La1 - x Al x FeO3 (x = 0.0, 0.05, 0.1, 0.2, 0.3, 0.4, and 0.5) nanopowders were prepared by polymerization complex method. All prepared samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FT-IR), and UV-vis spectrophotometry (UV-vis). The magnetic properties were investigated ...

Novel nano-catalysts (Nano ZnO and Fe doped ZnO (Fe(0.1)Zn(0.99)O) synthesized by co-precipitation method in aqueous solution as new nanocatalysts and characterized by common techniques as FTIR, XRD, SEM and UVD. The size of particles obtained from XRD data is 27 and 16 nanometers for ZnO and Fresno respectively. Influences of doped Fe on ZnO catalytic properties in oxidation of Benzylic alcoho...

The structural, morphological and magnetic properties of Co0.5Zn0.5Fe2O4 nanoferrite thin films on glass substrates were investigated by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM) and vibrating sample magnetometer (VSM), respectively. These thin films were deposited by spray pyrolysis method and subsequently calcined at 500 and 600 ˚C. The XRD results reveal th...
