In this article, multilayer nanowires (Ag/Co/Zn) were produced by electrochemical deposition in the form of anodic aluminum oxide. The electrochemical deposition method to produce nanowires are performed by three different methods. We have examined the pulsed periodic method, and we have managed to fabricate the nanowires of Ag/Co/Zn. Then, the produce nanowires are confirmed by the SEM and XRD analyses. Anodic nanoporous alumina with a thickness of 205 nm and a distance between pores of about 250 nm is produced by combining hard and soft anodization. Two-step anodization method including soft anodization and hard anodization was performed. These two anodizations were performed using 0.3 M oxalic acid as electrolyte at 0 degrees Celsius and applying voltages of 40 and 130 volts, respectively. Then the potential was reduced from 130V to 12V to thin the barrier layer. Multilayer nanowire arrays had been electrodeposited into the pores of anodic aluminum oxide (AAO) template. The electrochemical impedance spectroscopy has been carried out to study the in situ growth process of multilayer nanowires at different electrodeposition times.

In this research, Li1.25Mn0.125Ni0.125Co0.5O2 Nano powders, were synthesized using sol-gel method at different temperatures, lithium nitrate, manganese nitrate, nickel nitrate, cobalt nitrate as raw materials. Thermal and thermal gravimetric of TGA/DTA, characterization of structure properties of samples prepared by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) were performed. Also, with X-ray diffraction scheme, at different temperatures, it was concluded that the calcination temperature is suitable for synthesis. The size of Nano crystals was determined using Scherer and Williamson Hall method. The FTIR results showed that the metal bands in the 500 region increased sharply with increasing temperature to 850C, which is consistent with the XRD results.
