Grain BoundariesPerovskite manganites with general formula RE 1−x B x MnO 3±δ (where RE stands for a trivalent rare-earth element and B for a divalent alkaline ion) have been extensively investigated for their wide variety of intriguing properties, such as oxygen electrocatalysis in solid oxide fuel cell (SOFC), [1,2] The ORCID identification number(s) for the author(s) of this article can be found under https://doi.

The discovery of an original structure of the water at the inner surface of inorganic aluminogermanate nanotubes and its specific dynamics are reported, based on density functional theory molecular dynamics and inelastic neutron scattering.
