The rational design of Fe–N–C catalysts that possess easily accessible active sites and favorable mass transfer,which are usually determined by the structure of catalyst supports,is crucial for the oxygen reduction reaction(ORR).In this study,an oleic acid-assisted soft-templating approach is developed to synthesize size-controlled nitrogen-doped carbon nanoparticles(ranging from 130 nm to 60 nm and 35 nm,respectively)that feature spiral mesopores on their surface(SMCs).Next,atomically dispersed Fe–Nx sites are fabricated on the size-tunable SMCs(Fe1/SMC-x,where x represents the SMC size)and the size-dependent activity toward ORR is *** is found that the catalytic performance of Fe1/SMCs is significantly influenced by the size of SMCs,where the Fe1/SMC-60 catalyst shows the highest ORR activity with a half-wave potential of 0.90 V *** in KOH electrolyte,indicating that the gas-liquid-solid three-phase interface on the Fe1/SMC-60 enhances the accessibility of Fe–Nx *** addition,when using Fe1/SMC-60 as the cathode catalyst in aqueous zinc-air batteries(ZABs),it delivers a higher open-circuit voltage(1.514 V),a greater power density(223 mW cm^(−2)),and a larger specific capacity/energy than Pt/C-based *** results further highlight the potential of Fe1/SMC60 for practical energy devices associated with ORR and the importance of size-controlled synthesis of SMCs.

针刺启动是针刺效应的决定环节。目前已知,穴区内的肥大细胞脱颗粒是将针刺力信号向神经电信号转化的关键步骤,同时也被认为是针刺启动必要的指标。但是针刺力究竟如何导致肥大细胞脱颗粒这一议题尚无定论。此外,穴区中数量最多的成纤维细胞在针刺启动过程中扮演的角色以及与肥大细胞之间的相互作用并不明朗。然而这些问题可能就是阐明针刺启动机制的关键环节。文章从机械信号在穴区的转化、肥大细胞的角色、肥大细胞对机械信号的反应、成纤维细胞可能扮演的角色以及成纤维细胞与肥大细胞之间在穴区可能发生的相互作用加以讨论,提供一个手针针刺启动研究未来的方向。
