Spectroscopy

To avoid effects caused by quenching and/or incomplete freezing-in of defect chemical reactions, in-situ spectroscopic methods (elevated T, adjusted component activity (pO₂, pH₂O etc)) are preferable. Spectroscopic methods with spatial resolution for investigation of transport processes are also in the focus.

• Oxygen exchange on mixed conducting oxides: XPS under clo se-to-ambient conditions
• Nuclear Magnetic Resonance (solid state, PFG- and electrophoretic- NMR)
• Small Angle X-ray Scattering (SAXS)
• ESR
• optical
• SIMS + isotope exchange
• gas analysis MS, IR, GC for TG + catalysis
• EXAFS
