2014 We report an experimental study of the statics and dynamics of electrodeposition of zinc in an aqueous medium, in the intermediate regime between dendritic and DLA-like metallic clusters. During the growth process, periodic and nonperiodic oscillations of the voltage are recorded under constant applied current intensity. Period-doubling bifurcations are identified. Analysis of the data in ...

A tetrode is a bundle of four microwires that can record from multiple neurons simultaneously in the brain of a freely moving animal. Tetrodes are usually electroplated to reduce impedances from 2-3 MΩ to 200-500 kΩ (measured at 1 kHz), which increases the signal-to-noise ratio and allows for the recording of small amplitude signals. Tetrodes with even lower impedances could improve neural reco...

In this review paper, a critical analysis was carried out to investigate the effect of cathodic potential, bath temperature, time and nature of substrates on the ZnO thin films synthesized by electrodeposition technique. XRD patterns of the various deposited films were studied to examine the structural characteristics of the Nanostructured ZnO thin films. From the XRD patterns of the different ...

A facile synthetic approach to prepare porous ZnO@CuNi hybrid films is presented. Initially, magnetic CuNi porous layers (consisting of phase separated CuNi alloys) are successfully grown by electrodeposition at different current densities using H2 bubbles as a dynamic template to generate the porosity. The porous CuNi alloys serve as parent scaffolds to be subsequently filled with a solution c...

page 156 Abstract: The goal of this research is to fabricate a low cost and efficient solid state solar cell by coupling zinc oxide (ZnO) nanorods with a conjugated polymer of regio-regular poly(3-hexylthiopene) (P3HT). ZnO structures were grown onto FTO/nc-ZnO substrates through either hydrothermal solution phase or by electrodeposition and resulted in different morphologies depending on the g...

A three-dimensional, porous electrode composed of reticulated vitreous carbon (RVC) has been examined for the selective removal of metals by electrodeposition from single and multi-component solutions. A three-stage system was envisioned where each metal from a ternary mixture could be selectively removed in each stage. Single and multi-component solutions of copper, nickel, zinc and silver wer...

For the first time, ordered mesoporous ZnO nanoparticles have been synthesized by a template method. The electroplating after chemical plating method was creatively used to form copper film on the surface of the prepared ZnO, and then a CuO film-decorated ordered porous ZnO composite (CuO/ZnO) was obtained by a high-temperature oxidation method. In2O3 was loaded into the prepared CuO film-ZnO b...

A simple electrochemical deposition technique is used to synthesize both two-dimensional (nanowall) and one-dimensional (nanowire) ZnO nanostructures on indium-tin-oxide-coated glass substrates at 70°C. By fine-tuning the deposition conditions, particularly the initial Zn(NO(3))(2)·6H(2)O electrolyte concentration, the mean ledge thickness of the nanowalls (50-100 nm) and the average diameter o...

Anthropogenic sources account for much of the zinc (Zn) in the environment. Constraining the isotopic composition of anthropogenic Zn is therefore essential to understanding the environmental biogeochemical cycling of Zn isotopes. This study examines the isotopic variability in several different categories of anthropogenic Zn. Pure Znmetal and Zn dust are the rawmaterials used in many Zn-contai...

Hydrogen embrittlement of SK85 high-strength steel sheets was evaluated through a three-point bending test. The effects electroless Ni–P plating and Ni electroplating on hydrogen were examined with respect to the permeability plated films. On morrow plating, indicates high degree embrittlement, irrespective phosphorus content in film. However, is further suppressed than that which can be attrib...
