Oxygen pumping based on c-axis-oriented lanthanum silicate ceramics: Challenge toward low operating temperature" Vol. 127, No. 1, p. 1-4 Cover presents a schematic illustration of the oxygen pumping based on the oxide ionic conductors, the cross-sectional polarizing microscope image of c-axis oriented La 9.66 Si 5.3 B 0.7 O 26.14 electrolyte (c-LSBO) and I-V curves for the developed oxygen pumps based on c-LSBO. The oxygen flux of the c-LSBO based oxygen pump was significantly increased by the control of c-LSBO/electrode interface and the use of mixed conductive perovskite oxide electrode.
