Nam-In Kim,Young Jin Sa,Tae Sup Yoo,Sung Ryul Choi,Rana Arslan Afzal,Taekjib Choi,Young-Soo Seo,Kug-Seung Lee,Jun Yeon Hwang,Woo Seok Choi,Sang Hoon Joo,Jun-Young Park +11 more
TL;DR: A high-performance oxygen electrocatalyst based on a triple perovskite, Nd 1.5Ba1.5CoFeMnO9−δ (NBCFM), which shows superior activity and durability for oxygen electrode reactions to single and double perovSKites, and is the best activity reported to date.
Journal ArticleDOI

Amit Khare,Jaekwang Lee,Jaeseoung Park,Gi-Yeop Kim,Si-Young Choi,Takayoshi Katase,Seulki Roh,Tae Sup Yoo,Jungseek Hwang,Hiromichi Ohta,Junwoo Son,Woo Seok Choi +11 more
TL;DR: In this study, the orientations of the OVCs in BM-SrFeO2.5 are stabilized along two crystallographic directions of the epitaxial thin films and demonstrate a strong correlation between crystallographic orientations, electronic structures, and ionic motion in the BM structure.
