A Strategy Inspired by the Cicada Shedding Its Skin for Synthesizing the Natural Material NaFe(3)S(5)·2H(2)O (Adv. Sci. 21/2023)

Synthesizing the Natural Material NaFe(3)S(5)·2H(2)O In article number 2301324 by Hanqing Dai, Wei Wei, Guoqi Zhang, Ruiqian Guo, and co‐workers, a systematic approach for synthesizing NaFe(3)S(5)·2H(2)O (NFS) with water–oxygen stability by the high‐pressure hydrothermal method is presented. An analogy to cicada molting as a strategy for preparing unstable natural materials in water–oxygen conditions is also proposed. The limitations of the high‐pressure hydrothermal method are broken through, which hold significant scientific implications for its potential application in synthesizing lunar and Martian minerals. This work provides fundamental data of the NFS and a general route to synthesize newly discovered minerals based solely on their chemical formula. [Image: see text]
