Summary: This study demonstrates the production of thin coatings with different morphologies of bimetallic NiCo system on carbon felt by adjusting the pH of the electrolyte. The electrochemical performance of the coatings was evaluated using various techniques, showing that a smooth NiCo(s) coating is more effective as an electrocatalyst for the hydrogen evolution reaction compared to a rough NiCo(r). Equivalent circuits of the NiCo system on carbon felt were calculated and modeled based on the EIS results.

Summary: By depositing a ternary coating of Co-W-P on the surface of nickel foam, the overpotential of the hydrogen evolution reaction was reduced, resulting in a highly active electrode. It was found that W and P play different roles in the formation of nanoparticles, working together to achieve a larger electrochemical surface area and excellent activity. Higher intrinsic activity was obtained when W was introduced in the modification of other catalysts such as Ni-P and Fe-P.

Summary: A Ni-Co alloy catalyst with a unique succulent-plant-like morphology is prepared by electrodeposition, and the effects of deposition conditions on its performance are systematically investigated. The Ni-0.889-Co-0.111 catalyst shows excellent activity, selectivity, and stability in the borohydride oxidation reaction. Furthermore, when used as an anode catalyst in a direct borohydride fuel cell, it achieves a peak power density of 490 mW cm(-2) and an open-circuit voltage of 1.87 V at 343 K, and can operate stably for several hours. The improved performance of the Ni-Co catalyst is attributed to its unique morphology and the appropriate amount of Co.

Summary: This paper focuses on the electrodeposition of nanocrystalline Ni-W-Co ternary alloy film on copper substrate. The effects of electrodeposition parameters on the structural, compositional, surface characteristics, and corrosion properties of the alloy were investigated. It was found that the alloy has a uniform, compact, and flat surface with colony-like morphology. The crystalline structure and surface roughness are greatly influenced by the current density, bath pH, and plating time. Co content has little effect on crystallite size. The composition of the alloy shows a decrease in nickel content and an increase in Co content. The optimized process parameters for corrosion and wear resistance were determined.

Summary: The AC electrical properties of EVA- and NBR-based composites filled with different conductive fillers were investigated. The addition of these conductive fillers led to significant increases in AC electrical conductivity and dielectric permittivity, indicating their potential as supercapacitors. Different sigmoidal models were tested to determine the percolation threshold value of permittivity for these binary polymer composite systems, showing variation in results. The paper discusses the advantages, disadvantages, and limitations of these models, and compares them with classical percolation theory and results from published literature.
