β¦ Synopsis
An experimental
study of the effect of SCN ion concentration and laser bombardment intensity on the anodic dissolution of copper into an aqueous NaCl electrolyte is reported. The laser was used to accelerate the dissolution process. The results are analyzed in terms of power spectra, fractional Brownian motion theory and confocal image processing. An interpretation of the dynamic phenomena via the theory of nonlinear dynamics is also suggested.

Differences in the dynamic behaviour of the anodic dissolution of copper in aqueous NaCl and NaBr solutions containing SCN-ions were studied. In a neutral solution, addition of small amounts of NaBr to relatively concentrated NaCl solutions modifies oscillation amplitude, frequency and mean current
Investigations have been made on anodic dissolution of n-type germanium. Experimental conditions were achieved which enabled the construction of a potential/current (eJi+) diagram, in a broad current density range, which satisfies the condition pl = pO, ie the concentration of holes on the boundary
Various oscillation patterns observed in the -55 to -2OmV (see) range of the anodic potential are analysed by means of the experimental current density time series. Surface enhanced Raman spectroscopy indicates the presence of CuSCN in the anode film formed in the oscillatory regime, in addition to
