The Raman spectrum of vaterite prepared by electrochemical scaling in carbonically pure water is presented and analysed following the rules of group theory. It is shown that only one of the three crystallographic determinations already proposed for the structure of vaterite is compatible with the re

Impedance spectroscopy was used to study the initial stage of the spontaneous passivation of a metal immersed in a liquid electrolyte. The error in the measured impedance responses due to the time variability of the passivating system is discussed and evaluated. Three models of impedance response du
Zinc dissolution and passivation in either arsenate or borate and a mixture of arsenate-borate solutions at pH 8.9 was studied by polarization curves and cyclic voltammetry. The arsenate anion produces an increase on zinc dissolution . Potential sweep rate, rotation speed, temperature, dissolved oxy
