Bias-triggered conductivity relaxation (BCR): a unique tool to simultaneously investigate thermodynamics, kinetics and electrostatic effects of oxygen reactions in MIEC thin films
Alexander Stangl, Alexander Schmid, Adeel Riaz +2
Mixed ionic electronic transfer (MIET) reactions, such as the oxygen reduction reaction (ORR) at oxide surfaces, are of paramount importance to manifold technologically highly rele…
Investigating oxides by electrochemical projection of the oxygen off-stoichiometry diagram onto a single sample
Alexander Stangl, Alexander Schmid, Adeel Riaz +10
The oxygen stoichiometry is an essential key to tune functional properties of advanced oxide materials and thus has motivated numerous studies of the oxygen off-stoichiometry diagr…
In situ Study of Phase Transitions in LaNiO using Raman Spectroscopy
Adeel Riaz, Alexander Stangl, Mónica Burriel +1
LaNiO has attracted increasing interest in recent years, both as oxygen electrode in solid oxide fuel cells and electrolysers due to its high electrochemical activity…
Exploring the potential of combining over- and under-stoichiometric MIEC materials for Oxygen-Ion Batteries
Silvère Panisset, Alexander Schmid, Alexander Stangl +3
The increasing demand for energy storage solutions has spurred intensive research into next-generation battery technologies. Oxygen-ion batteries (OIBs), which leverage mixed ionic…
