Abstract Ionic diffusion in solids underpins energy storage, electronics, and catalysis, yet conventional diffusion models often fail to capture complexities arising from confinement, crystallographic disorder, lattice distortions, and coupled transport with phonons or electrons. These challenges are particularly pronounced in battery materials, where ionic and electronic carriers move together, complicating the interpretation of electrochemical measurements.

Abstract Matter exhibits strikingly different structures and behaviours in strongly confined spaces compared with its bulk form. These differences become particularly pronounced when the confinement is reduced to the ångström scale, comparable with the characteristic size of atoms, ions and molecules.

Abstract β-Strand motifs are essential recognition modules in protein-protein interactions (PPIs), which govern cellular signaling networks and regulate molecular pathway dynamics. Herein we present an unexpected discovery of a previously uncharacterized β-strand insertion mechanism termed as cross-β-strand linking, wherein β-strands within the β-sheet-rich aggregates form inter-β-sheet connections through insertion into adjacent β-sheets.
