For achieving the high quality of titanium dioxide (TiO$_2$) nanorods, herein, we present a synthesis of rutile TiO2 nanorods on a transparent conductive fluorine-doped tin oxide (FTO) glass substrate with seed layer by a two-step method. Anatase TiO$_2$ thin films were first precoated by spin coating and annealing, followed by the growth of rutile TiO$_2$ nanorods with a hydrothermal method....
Co$_{0.05}$LaTi$_{0.95}$O$_3$ nanofibers with average diameter of 201 – 264 nm have been successfully fabricated by electrospinning method. The crystal structure of nanofibers calcined at 400 – 700 $^o$C shows amorphous structure. The Co$_{0.05}$LaTi$_{0.95}$O$_3$ nanofibers calcined at 800 oC had cubic perovskite-type structure with secondary phase. The average crystallite sizes of nanofibers...
Current carrying spherical coils are used to generate the magnetic field to cancel the Earth’s Magnetic Field (EMF) on an interesting spherical surface. The currents in the spherical coils, which minimize the residue from the EMF cancellation, are determined by the steepest descent optimization method. In this study, two configurations of the spherical coils are considered. Considering the...
Crystalline zinc oxide powders are prepared by a direct thermal decomposition of zinc nitrate hexahydrate in air at 500 oC for 2 h. The thermal behavior of zinc precursor compound was studied using TG-DTA analysis in order to define the ZnO formation temperature. The structure of the calcined sample was characterized by X-ray diffraction (XRD). The XRD result indicates that the sample has a...
