Abstract Grain-boundary atomic structures of crystalline materials have long been believed to be commensurate with the crystal periodicity of the adjacent crystals. In the present study, we experimentally observed a Σ9 grain-boundary atomic structur

The effect of aliovalent doping on grain boundary is not yet fully understood at the atomic level. Here, the authors report grain boundary structural transformation in α-Al2O3 is induced by co-segregation of multiple dopants using atomic-resolution

Abstract Grain boundary (GB) migration is one of the most important phenomena in materials science, which plays a key role in modifying the microstructures and properties of polycrystalline ceramic materials. Understanding how GB migrates is thus a f

Grain boundaries can improve the radiation resistance of a material by annihilating point defects formed under irradiation, however the atomistic mechanism is still unclear. Here the authors demonstrate grain boundaries absorb point defects through t

The delithiation process in lithium excess cathode material of Li2MnO3 has remained unclear. Here, the authors report that delithiation is governed by the climb motion of dislocations with the aid of oxygen-release, determined directly by atomic-reso
