Temporal patterns and oscillatory voltage perturbation during an electrochemical process

The response of electrodissolution dynamics of nickel in sulfuric acid electrolyte was studied and categorized using efficient signal processing techniques. Time-frequency and phase analysis revealed complex dynamical patterns in anodic currents observed in the system. These patterns which respond to three-dimensional changes in the electrolyte and surface conditions, have a multitude of spatio-temporal properties which proved sensitive to …
