nicu alloy nanowires arrays were embedded into the anodic aluminum oxide (aao) template by ac-pulse electrodeposition. different off-time were used in electrolyte with constant concentration of ni and cu and acidity of 3. the effect of deposition parameters on alloy contents was investigated by studying the microstructure and magnetic properties of as-deposited nicu alloy nanowires. atomic forc...

A common production method for nanowires is based on electrodeposition into cylindrical channels of a nanoporous template. Since the nanostructures adopt the morphology given by the host material as they are created by reduction from an electrolyte solution, the deposition step can be considered as the most important factor that determines the structure. Pt nanostructures are of particular inte...

A patterned coreeshell tin (Sn) nanorod anode is fabricated by pulse electrodeposition of Sn onto a selfassembled Tobacco Mosaic Virus (TMV) structured nickel current collector. Pulse electrodeposition onto the virus assembled 3D electrode surfaces produces homogenous Sn coatings with significant void space to accommodate the large volume change associated with Sn lithiation. The TMV enabled 3D...

A combined cyclic voltammetry and pulse reverse potential electrodeposition technique has been used to synthesize carbon-free Ni/NiO nanocomposite thin film supercapacitor electrode. The structural morphological analyses have revealed the presence of crystalline phases both Ni NiO in form nanospheres size ~50 nm. electrochemical analysis Ni/NiOna nocomposite electrode shown a remarkable perform...

High capacitance Co-Co3O4 nanocomposite thin films have been synthesized on nickel foam (NF) using cyclic voltammetry (CV), combination of and potentiostatic (CV PS −1.4 V CV +1 V), pulse reverse potential PRP) modes electrodeposition. X-ray diffraction (XRD) studies reveal the presence Co Co3O4 phases for four electrodeposition modes. The scanning electron microscope (SEM) revealed an interest...

Electrochemical synthesis followed by heat-treatment is a facile and easy method for preparation of nanostructured metal oxides. Herein we report nanostructured Mn5O8 prepared through pulse cathodic deposition followed by heat-treatment for the first time. For the preparation of Mn5O8 nanorods, pulse cathodic electrodeposition was first done from 0.005M Mn(NO3)2 at the current density of 5 mA c...

Zinc-Nickel electrodeposits have been widely adopted for surface treatment of automobile steel sheet for high corrosion resistance. In this work the effect of pulse parameters on the Zn-Ni alloy electrodeposits was investigated. The hardness, thickness, corrosion resistance and composition of deposits thus produced were investigated. The surface topography of the deposits was also observed in S...

In NaCl-KCl-NaF-V2O3 molten salt, used graphite as an anode and carbon steel plate a cathode, vanadium was successfully prepared by salt electrodeposition. The reduction mechanism of electrodeposition is discussed, the influence NaF content, current density, temperature, time on are studied. optimum conditions obtained: composition XNaCl = 0.4, XKCl XNaF 0.2, V2O3 15%; adopt bidirectional pulse...
