The Cover Feature shows the potential-driven phase transformation of Manganosite (MnIIO) to layered Birnessite (MnIII,IVO2) in alkaline media. In their Full Paper, H. Radinger et al. investigate structural and chemical evolution various MnOx thin films as electrocatalysts for oxygen reaction by X-Ray photoelectron operando Raman spectroscopy. displayed conversion with intercalated water molecules potassium ions is responsible electrochemical performance. Nevertheless, starting material defines electrocatalytic activity after an activation treatment. More information can be found Paper
