Summary: The use of artificial nuclei in electrodeposition facilitates uniform and stable Cu nanoobject fabrication within nanopores, providing precise control over the geometry of the nanoobjects. This approach effectively suppresses random overgrowth of Cu, achieving highly uniform distribution on substrate surfaces.

Summary: A comparative study was conducted on the electrochemical deposition of cobalt on tin-doped indium oxide (ITO) substrate using electrochemical techniques in nitrate and chloride electrolytes. The results showed that cobalt deposition at a negative potential in both electrolytes was diffusion-controlled, with different nucleation mechanisms observed in nitrate and chloride solutions. X-ray diffraction analysis confirmed a hexagonal crystal structure for the cobalt deposited on ITO substrate regardless of the electrolyte composition.

Summary: This work focused on investigating the growth of V2O5 nanostructures and their application as HTL in PSCs. It was found that tuning the solution concentration and precursor nucleation time played a crucial role in the growth of V2O5 NRDs, which exhibited excellent electrochemical properties and conductivity. Among different morphologies of V2O5 nanostructures, V2O5 NRDs showed the highest charge mobility and performance.

Summary: Zinc telluride (ZnTe) is a promising material for optoelectronic and photovoltaic device applications due to its optimal characteristics in terms of environmental compatibility, abundance, and photoactivity. This study revealed that the electrodeposition of ZnTe on an indium tin oxide substrate is a quasi-reversible reaction controlled by diffusion, following the nucleation and growth mechanism proposed by Scharifker and Hill. The crystallographic structure of the ZnTe films was found to be cubic, and the films exhibited good homogeneity. Optical measurements showed a direct energy gap of 2.39 eV for the deposited films.

Summary: In this paper, the electrochemical behavior of electrodeposited Cu in ultra-high acidity sulfate systems under different ultrasonic field powers was studied. The results show that the ultrasonic field significantly improves the mass transfer rate in the electrodeposition process, forming uniform and dense micro-nano layers.

Summary: The formation of hemispherical porn-porn-like clusters of nanowires during potentiostatic oxidation of copper in NH4HCO3 was reported. The nanowires, mainly composed of CuO, Cu2O, Cu(OH)(2), and Cu4O3, had a diameter of approximately 50-70 nm, while the clusters had a diameter ranging from 1-3 μm and strongly depended on the applied potential and time of electrooxidation.

Summary: The study investigates the anodization of copper foams in 0.1M K2CO3, resulting in nanostructures that show potential for photocatalytic decolorization. Samples anodized at 25V and 5V exhibited the highest photocatalytic activity. The anodized copper foams have shown to enhance the efficiency of organic dye decomposition.

Summary: The effect of applied potential on the properties of co-electrodeposited Cu2CoO3 on ITO substrate was investigated. The electrochemical behavior indicated quasi-reversible reaction controlled by diffusion. XRD analysis showed orthorhombic structure with (011) preferred orientation. Surface morphology changed with applied potential. In addition, the optical properties demonstrated an increased band gap energy and the layers were determined to be p-type semiconductors with increasing acceptor density.

Summary: Mixed transition metal oxides are promising electrode materials for electrochemical energy storage and conversion. The synthesis of these materials with tailored composition, crystal structure, and morphology is crucial for optimizing their properties. This study reports on the room-temperature electrodeposition of a ternary oxide, ZnMnO3, using earth-abundant metals. The epitaxial growth of ZnMnO3 on ZnO nanowires results in a 2-dimensional morphology and shows promise for the direct growth of other mixed transition metal oxides on conductive substrates.

Summary: In this work, a layer-by-layer electrodeposition method was used to fabricate copper-cobalt oxide thin films on FTO glass. Thermal treatment was applied to obtain a stable oxide structure. The synthesized coatings exhibited bifunctional electrocatalytic activity in water splitting reactions and also showed potential as pseudocapacitors.

Summary: The nucleation of lithium directly on the copper current collector in anode-free lithium-metal batteries is limited by poor control and diffusion of lithium into the copper substrate via grain boundaries. Prelithiation of the copper surface improves the nucleation process by saturating the surface with lithium, reducing the influence of lithium diffusion. This leads to more homogeneous lithium nucleation, especially when a short potentiostatic nucleation pulse is applied.
