Nickeliferous pyrrhotite tailings, from Vale's Clarabelle Mill, were oxidized at 140 °C and 690 kPa (using compressed O2) in an electrolyte with an initial composition of 50 g/L H2SO4 and 2.25 g/L of Fe2(SO4)3. These conditions are similar to those

The properties of alkylthiol self-assembled monolayers (SAMs) on Au have been extensively characterized in the past few decades by exploiting a one-electron reductive desorption process. To date, oxidative desorption of thiol SAMs has been relatively
