Effect of Electrochemical Factors on Formation and Reduction of Silver Oxides
International Journal of Electrochemical Science, 2013 Polarization of silver in NaOH solution with various electrochemical parameters was investigated by cyclic voltammetry and scanning electron microscope. The resulting cyclic voltammograms reveal that the observed midpoint potential and current density of

Electrochemical study of the Eu(III)/Eu(II) system in molten fluoride media [PDF]
, 2009 The electrochemical behaviour of the Eu(III)/Eu(II) system was examined in the molten eutectic LiF-CaF2 on a molybdenum electrode, using cyclic voltammetry, square-wave voltammetry and chronopotentiometry. It was observed that EuF3 is partly reduced into

A new insight into the oxidative mechanism of caffeine and related methylxanthines in aprotic medium: May caffeine be really considered as an antioxidant? [PDF]
, 2018 Background: Antioxidant properties have been recently suggested for caffeine that seems showing protective effects against damages caused by oxidative stress. In particular, a HO% scavenging activity has been ascribed to caffeine. Even if the oxidation
