“…Yu et al [19] investigated the temperature dependence of the electrocrystallization of zinc onto a glassy carbon (GC) electrode using cyclic voltammetry and chronoamperometry measurements and found that increasing the temperature increased the nucleation density and modified the nucleation mechanism of zinc electrodeposits. Higashi et al [20] has developed zinc hydroxide layer suppression mechanisms for zinc deposition in acid sulfate baths, which has been confirmed by other authors [21,22]. Sonneveld et al [23] reported that zinc nucleation from a zincate solution on carbon substrate can be interpreted by a model involving instantaneous nucleation in conjunction with three-dimensional hemispherical growth.…”

The nucleation and first stages of the growth of zinc on aluminum from acidic sulfate solution in the absence and presence of 1-butyl-3-methylimidazolium hydrogen sulfate-[BMIM]HSO 4 as additive were investigated using cyclic voltammetry, chronoamperometric current-time transients, and scanning electron microscopy techniques. The dimensionless chronoamperometric current-time transients for the zinc electrodeposition on aluminum electrode from the solution free of [BMIM]HSO 4 showed the zinc deposition can be interpreted by a model involving instantaneous nucleation with hemispherical diffusion controlled growth of nuclei. The addition of [BMIM]HSO 4 induced a blocking effect on the zinc electrocrystallization process through its cathodic adsorption on the electrode surface. This effect led to increase the number density of active sites, decrease the nucleation and growth rate of these nuclei, and produce more leveled and fine-grained cathodic deposits without affecting the instantaneous nucleation mechanism. Surface morphology analysis revealed the crystal structure of the zinc deposits formed did not change by the adsorption of [BMIM]HSO 4 at the first stages of deposition.

“…At the potential region less-noble than the equilibrium potential of Co, the cathodic current increases again at around -0.8V. It is also well known that the electrodeposition of iron-group metals such as Ni, Co and Fe accompanies with the overpotential [11][12][13] due to the rate determining of multi-step reduction mechanism [11].…”

A nano-porous anodized aluminum oxide layer was synthesized on the surface of bulk aluminum at a wide range of anodization voltages. The barrier layer at the pore bottom of anodized aluminum oxide layer was chemically etched to make good electrical contact for nanowires electrodeposited in the pores thus formed on metallic aluminum substrates.Cathodic polarization was examined at a wide range of cathode potentials to investigate the electrodeposition behavior of Cu and Co into the pores. Co 81 Cu 19 /Cu multilayered nanowires were fabricated using a pulse-plating technique into the templates. Co-alloy layer and Cu layer thicknesses were adjusted to 10nm, by controlling the deposition times. The temperature dependence of the resistance of Co 81 Cu 19 /Cu multilayered nanowires grown on the template presented clean metallic characteristics and a giant magnetoresistance (GM R) of 23% was reached at 4K.

“…Formation of zinc hydroxide species on the surface at À0.98 V is impossible at this pH value owing to high value of hydrogen overpotential on zinc-rich alloy. Therefore the ''anomalous'' behavior, in our opinion, can not be explained by hydroxide suppression mechanism put forward by Dahms [11] and advocated by Shibuya [6] and Fukusima [7,12,13].…”

“…Many hypotheses have been used for the explanation of characteristic features of so-called ''anomalous'' type co-deposition. The hydroxide suppression mechanism (HSM) was considered to be most plausible [6,7]. However, there is no satisfactory explanation of all salient features of ''anomalous'' co-deposition of zinc with nickel (also with iron and cobalt) at present.…”
