The Sr segregation at the surface of a perovskite La0.6Sr0.4Co0.2Fe0.8O3-δ (LSCF) oxygen electrode is detrimental to the electrochemical performance and durability of energy conversion devices such as solid oxide fuel cells. However, a quantitative

Three-dimensional human pose estimation can be effectively applied to teleoperation of humanoids, thanks to its intuitive and easy usability. However, the human pose wrongly inferred can cause critical and dangerous situations for robotic operation.

The Er2O3-stabilized Bi2O3 (ESB) exhibits a superior oxygen ion conductivity below 750 oC. However, there is significant conductivity decay due to a cubic-to-rhombohedral phase transformation over time at ~ 600oC. Thus, to enhance the kinetic stabili

We develop a novel nanocomposite electrolyte, consisting of yttria-stabilized zirconia (YSZ) and erbia-stabilized bismuth oxide (ESB). The 20 mol% ESB-incorporated YSZ composite (20ESB-YSZ) achieves the high density (>97%) at the low sintering temper

Rare earth stabilized bismuth oxides have attracted much attention due to their high oxygen ionic conductivity. Among singly-doped stabilized bismuth oxides, the Er2O3-stabilized Bi2O3, which is generally abbreviated to ESB, is particularly known for
