Oxygen conduction at low temperatures in apatites make these materials potentially useful as electrolytes in solid-oxide fuel cells, but our understanding of the defect structures enabling ion migration is incomplete. While conduction along...
New oxybromide cobaltites with layered perovskite-related structures: 18R-Ba(6)Co(5)BrO(14) and 14H-Ba(7)Co(6)BrO(17) [0.03%]
