The structure of nanocrystallized zirconia has been investigated in the 1–40-GPa pressure range at ambient temperature. A continuous transformation towards the ideal fluorite cubic structure is observed from 8 GPa. The complete transformation seems to be achieved at 30 GPa. The compressibility of the tetragonal and cubic forms are derived and discussed.

Significant enhancement in the catalytic activity of the benchmark (LaSr)(CoFe)O3−δ (LSCF) electrode is obtained by modifying the A-site non-stoichiometry.
