In displaying accelerated oxygen diffusion along extended defects,(La, Sr) MnO3+ δ is an
atypical acceptor‐doped perovskite‐type oxide. In this study, 18O/16O diffusion experiments …

Interface‐dominated materials such as nanocrystalline thin films have emerged as an
enthralling class of materials able to engineer functional properties of transition metal oxides …

Ion transport in solid-state devices is of great interest for current and future energy and
information technologies. A superior enhancement of several orders of magnitude of the …

The current description of oxygen-vacancy behaviour in (La, Sr) MnO3 perovskite-type
oxides, though widely accepted, ignores a pronounced discrepancy. Values of the activation …

Grain boundaries in Sr-doped LaMnO 3±δ thin films have been shown to strongly influence
the electronic and oxygen mass transport properties, being able to profoundly modify the …

In this chapter, we present an overview of the different approaches currently followed to
fabricate nanostructured electrodes (at the volume and surface level) as well as the reported …

For an oxygen electrode in solid oxide fuel cells (SOFCs) consisting of mixed electrical and
ionic conducting lanthanum strontium cobalt ferrite (LSCF), it degrades due to its low …
