Electrochemical corrosion behavior of α-titanium alloys in simulated biological environments (comparative study).

Titanium (Ti) and its alloys are widely utilized in orthopedic and dental applications due to their favorable mechanical properties and biocompatibility. Notably, titanium exhibits excellent corrosion resistance and can form a stable oxide layer, ensuring the longevity and functionality of implants in challenging physiological environments. This study investigates the corrosion behavior of α-Ti alloy in physiological saline solutions, emphasizing the role of key biomolecules found in the human body, including albumin, glycine, and glucose, as well as additional substances such as hydrogen peroxide (HO) and hydroxyapatite (Hap).

Electrodeposition of CuNiSnS absorber layer on FTO substrate for solar cell applications.

Potentiostatic and electrochemical impedance spectroscopy (EIS) measurements were recorded to study the nucleation and growth mechanisms of electrodeposited CuNiSnS (CNTS) thin films from aqueous solution at different applied potentials. The electrodeposition process of Cu-Ni-Sn-S precursors were studied using cyclic voltammetry and chronoamperometry techniques. The nucleation and growth mechanism of these films was found to follow a three-dimensional progressive nucleation limited by diffusion-controlled growth.
