Opis:: In this study, Sn nanowires were produced electrochemically in anodic aluminum oxide membranes. During the deposition process some parameters such as ion content, pH, deposition time, and temperature of solution were kept constant. The scanning electron microscope results showed that the diameters of produced tin nanowires were approximately 300 nm and their lengths were about 8-10 μm. Electrochemical impedance studies of Sn nanowire arrays were also studied by Iviumstat galvanostat/potentiostat system.

Opis:: In this work, NiFe nanowires were grown in highly ordered porous anodic alumina oxide templates by dc electrodeposition at a pH value of 2.6. Scanning electron microscopy showed that wires have diameters of about 250-310 nm and length 25-30 μm. The energy dispersive X-ray analysis showed that the composition of the nanowires is $Ni_{65}Fe_{35}$. Electrical contacts were made on both sides of the nanowire array and their magnetoimpedance properties were investigated. All the magnetoimpedance curves showed single peak behavior due to the high shape anisotropy. The maximum magnetoimpedance change at the 79 MHz driving current frequency was ≈ 1.45%.

Opis:: Co/Cu multilayer nanowires were electrodeposited potentiostatically on highly ordered porous anodic alumina oxide templates. Scanning electron microscopy (SEM) showed that wires have diameters of about 250-300 nm and length of 40-50 μm. Co/Cu multilayer nanowire arrays embedded in anodic alumina oxide were mechanically polished with diamond in a suspension of oil until the wires appeared. Then the top and bottom surfaces of the material were coated with a layer of Au with a thickness of 100 nm for electrical contacts. Magnetic field was applied by an electromagnet and resistance was measured by four point technique.

Opis:: CoNiFe and NiFe nanowires were electrochemically produced by dc electrodeposition on highly ordered porous anodic alumina oxide templates. Scanning electron microscope images of nanowires after removing the alumina membrane showed that these nanowires are uniform with the diameters of about 220-300 nm and about 25-30 μm length. The energy dispersive X-ray analysis showed that the composition of the nanowires is $Ni_{88}Fe_{12}$, $Co_7Ni_{82}Fe_{11}$. Magnetic field was applied by an electromagnet and resistance was measured by four point technique.

Opis:: In this study, densely packed $Co_3O_4$ nanotubes for supercapacitors have been obtained by means of chemically depositing cobalt hydroxide within a porous anodic aluminum oxide and then annealed at 360°C. The morphological properties obtained $Co_3O_4$ nanotubes were studied by scanning electron microscopy, the chemical composition was determined by examination of the energy dispersive X-ray spectra. Supercapacitor characteristics such as charging/discharging and impedance (Z) characteristics were also examined.

Opis:: In this study, free standing NiO nanostructures for supercapacitors were obtained by means of chemically depositing of nickel oxide on Ni foam and then they were annealed at various temperatures. The morphological properties of densely covered Ni foams were studied by scanning electron microscopy. Supercapacitor characteristics, such as charging/discharging and impedance characteristics, were also examined.
