Ternary Sn88Ag5Cu7, Sn93Ag4Cu3, Sn58Ag18Cu24, Sn78Ag16Cu6, Sn90Ag4Cu6, Sn87Ag4Cu9alloy nanowires were produced at various values of deposition potential by dc electrodeposition on highly ordered porous anodic alumina oxide (AAO) templates. During the deposition process some parameters, such as ion content, deposition time, pH, and temperature of the solution, were kept constant. The diameter and length of regular Sn93Ag4Cu3nanowires electrodeposited at −1 V were determined by scanning electron microscopy (SEM) to be approximately 200–250 nm and 7-8 μm, respectively. Differential scanning calorimetry (DSC) results indicate that the melting onset temperature of Sn93Ag4Cu3nanowires is about 204°C.

In this study, densely packed Co3O4 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 Co3O4 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.

In this work, the technological aspects of great importance YBa2Cu3O7−x superconducting materials were produced in the form of nanotube by electrochemical method. The electrochemical deposition conditions for the YBaCu deposition in nanoporous Al2O3 were investigated. The heat treatment was applied to YBaCu/Al2O3 nanopatterns, to form superconductive phase. The resulting nanostructures were found to be in length 45 µm, 177210 nm in diameter. The produced nanostructures at −4 V and more positive potentials were YBaCu nanowires, while the nanostructures deposited at the more negative potentials were of nanotube form.
