Journal ArticleDOI
Time-Resolved in Situ Studies of Oxygen Intercalation into SrCoO2.5, Performed by Neutron Diffraction and X-ray Absorption Spectroscopy
TL;DR: It is observed here, for the first time, 3D oxygen ordering during an oxygen intercalation reaction, as established for SrCoO(2.82)(+/-)(0.07), which can be described as a tetragonal unit cell, related to the perovskite cell by a approximately 2(a radical2) and c approximately 2a.
Journal ArticleDOI
Anisotropic oxygen diffusion at low temperature in perovskite-structure iron oxides
TL;DR: The results demonstrate that oxygen diffusion in the brownmillerite is highly anisotropic, significantly higher along the lateral direction of the tetrahedral and octahedral layers.
Journal ArticleDOI
Lattice Dynamics To Trigger Low Temperature Oxygen Mobility in Solid Oxide Ion Conductors
Werner Paulus,Helmut Schober,Stefan Eibl,Mark R. Johnson,Tanguy Berthier,Olivier Hernandez,Monica Ceretti,Marie Plazanet,Kazimierz Conder,Carlo Lamberti +9 more
TL;DR: The decisive impact of lattice dynamics, giving rise to structural instabilities in oxygen deficient perovskites, especially with brownmillerite-type structure, is demonstrated, opening new concepts for the design and tailoring of low temperature oxygen ion conductors.
