On the cover: The pace of science and technology is accelerating, and the future is arriving much faster. During the great process of reaching the future, the now highly comprehensive and interdisciplinary network of science, so-called 'ScienceX' by The Innovation, plays a more important role than ever before. We believe the development of interdisciplinary science and technology concerns our destiny in the coming future. |

Single-site metal atoms (SMAs) on supports are attracting extensive interest as new catalytic systems due to maximized atom utilization and superior performance. However, rational design of configuration-optimized SMAs with high activity from the perspectives of fundamental electron spin is highly challenging. Herein, N-coordinated Fe single-atoms are successfully distributed over axial carbon micropores to form dangling-FeN4 centers (d-FeN4). This unique d-FeN4 demonstrates much higher intrinsic activity towards oxygen reduction reaction (ORR) in HClO4 than FeN4 without micropore underneath and commercial Pt/C.
