Understanding cation-disordered rocksalt oxyfluoride cathodes

A “concerted-densification” based failure mechanism, involving atomic-level changes in both transition-metal cationic sublattice and oxygen/fluorine anionic sublattice, is proposed for the degradation of F-DRX cathode materials.

Perovskite hetero-anionic-sublattice interfaces for optoelectronics and nonconventional electronics

Perovskite hetero-anionic-sublattice interfaces can provide a new platform for emergent phenomena that may or may not have homo-oxygen-sublattice interface analogues.

Synthesis and structural studies of a new complex ofcatena-poly[p-anisidinium [[diiodidobismuthate(III)]-di-μ-iodido] dihydrate]

A new organic–inorganic hybrid material, {(C7H10NO)[BiI4]·2H2O}n, has been synthesized by slow evaporation of an aqueous solution at room temperature. The anionic sublattice of the crystal is built up by [BiI6] octahedra sharing edges. The resulting zigzag chains extend along thea-axis direction and are arranged in a distorted hexagonal rod packing. Thep-anisidinium cations and the water molecules are located in the voids of the anionic sublattice. The cations are linked to each other through N—H...O hydrogen bonds with the water molecules, and also through weaker N—H...I interactions to the anionic inorganic layers.
