A08N

Sub-project A08N provides a local structural understanding of iron-based oxides. We use a multimodal analytical approach, including transmission electron microscopy coupled with electron energy loss spectroscopy and energy dispersive X-ray spectroscopy, positron annihilation lifetime spectroscopy, as well as pair distribution function analysis, to identify local structural arrangements and understand their influence of iron surroundings. Additional insights from in situ and operando electron microscopy provide information on the extent to which the structure can be tuned by co-feeding water.
