1. Estudo da corrosão localizada da liga de alumínio 7475-T761 por espectroscopia de impedância eletroquímica global e local em meio de sulfato de sódio. / Localized corrosion study of aluminum alloy 7475-T761 in sulfate medium using global and local electrochemical impedance spectroscopy.
Aluminum alloys used in the aerospace industry with structural purpose exhibit a complex microstructure due to thermal and mechanical treatments they are submitted for improving their strength. The microstructure of these alloys is characterized by the presence of a great number of intermetallic (IM) particles, the electrochemical activity of which is differ

2. Equilibrium Potentials of Membrane Electrodes
A simple thermodynamic theory of the equilibrium potentials of membrane electrodes is formulated and applied to the glass electrode for measurement of pH. The new formulation assumes the selective adsorption or binding of specific ions on the surface of the membrane which may or may not be permeable to the ion, and includes the conventional derivation based
