“…We will show that the presence of Cu(ClO 4 ) 2 in our acidic electrolyte contributes to the corrosive environment, the final component of SCC. [54,56] For Cu films, we observed a strong dependence of the fracture propagation rate on the concentration of Cu 2+ in the electrolyte (Cu(ClO 4 ) 2 ) (Table S4, Supporting Information). With 5 and 10 mm [Cu 2+ ] through thickness cracks propagated >2 cm in less than 1 day (Figure S15, Supporting Information), but with 0.5 mm [Cu 2+ ] there were no signs of fractures until 14 days of electrolyte soaking.…”

Zn) to dynamic glazings with applications for thermal emissivity (e.g., Ag) or windows (e.g., Cu, Bi, Ag, and Zn). In each of these systems, a layer of metal is electroplated for the system's designed purpose: energy storage for batteries, [1][2][3][4] infrared light modulation for dynamic thermal emissivity, [5] and visible light modulation for dynamic windows. [6][7][8] The mechanical stability of the electrodeposited films is paramount for the devices' durability in practical applications. Mechanical failure can occur in the form of detached dendrites, "dead" metal, pits, and cracked or delaminated films, which usually result in loss of active material leading to device failure. The mechanics of electrodeposited Li has been extensively studied for Li metal batteries. [9,10] Dynamic windows allow for electronic and user control over light and

“…This is possible inasmuch as additives can modify the mechanisms of mass and charge transfer, the kinetics of metal reduction, and the molecular interactions and in general the structure of the electrical double layer. It has been reported that the addition of thiocyanate in metal electrodeposition baths helps to produce metal coatings that inhibit the corrosion of ferrous substrates (1,2). For example, this additive has been successfully used in the electrodeposition of Co and Ni (3).…”

Thiocyanate (SCN-) is widely used in industrial and scientific areas; nevertheless, few studies have been made to understand the mechanism of adsorption and electrochemical oxidation of SCN-. This work shows the results of a study of the adsorption and oxidation of SCN- at different concentrations on a Pt electrode in a 0.1M HClO4 electrolyte solution. In the behavior of this system, studied with an Electrochemical Quartz Crystal Microbalance (EQCM) coupled with Cyclic Voltammetry (CV), we observed an irregular tendency of anodic current with respect to the concentration of the additive. To understand this, we used Electrochemical Impedance Spectroscopy (EIS), testing four different reaction mechanisms that involve the adsorption and oxidation of thiocyanate. For each one of the tested mechanisms a transfer function was proposed and fitted to the experimental data. According to the pattern recognition method, the best fitted mechanism involves the formation of (SCN)2 as an intermediate.
