However, the practical application of RAZBs is severely impeded by the uncontrollable hydrogen evolution reaction, serious self‐corrosion, and uneven zinc deposition. Herein, the study proposes a multifunctional electrolyte additive to form in situ a protective layer on zinc surface, providing a buffering ability of maintaining the stable pH around anode/electrolyte interface and thus inhibiting hydrogen evolution reaction. Additionally, the modified Zn anode shows the preferred orientation growth of (101) plane, inheriting the merits of dense deposition morphology and superior stability. Consequently, the Zn||Zn symmetric cell demonstrates a remarkable life span up to 4000 h (1 mA cm−2, 1 mA h cm−2) and 1300 h (5 mA cm−2,1 mA h cm−2). After cycling over 1500 h, the Zn||Cu half cell shows a high coulombic efficiency for nearly 100%, verifying the extraordinary Zn stripping/plating reversibility. The as‐assembled Zn||MnO2 full battery shows good electrochemical characteristics, surpassing the bare cell without the additive. This investigation features a facile yet effective strategy for ultradurable Zn anode design and sheds the light on designing practical rechargeable metal batteries.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"74 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143782442","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Deep eutectic solvents (DESs) show great potential to replace conventional inorganic acids due to their eco‐friendly, low‐cost, and superior leaching performance. However, the low solid–liquid ratio, high leaching temperature, and complex stepwise recovery processes may lead to large solvent and energy consumption. Herein, a selection principle is proposed according to the enhanced redox capacity and abundant hydrogen bonding interactions, which help to design novel ternary DESs. The results demonstrate that the DESs could disrupt metal–oxygen bonds efficiently and reduce high‐valent metals to form low‐valent metal complexes in solution. Besides, water as a dilutant can reduce the viscosity of DESs and benefit to form abundant hydrogen bonds. As a result, the DESs can achieve high‐metal leaching efficiency of 98.65% (Li), 96.92% (Ni), 96.94% (Co), and 95.53% (Mn) at relatively low temperature (60 °C) and high solid–liquid ratio (RS/L = 10), respectively.

Herein, a facile strategy is presented for multi‐parameters switchable RTP by introducing second H‐bonding units (SHUs) capable of adsorption and desorption, such as H2O and DMSO, into hydrogen‐bonded organic crystals. It is found that the incorporation of H2O molecules into the HOC‐PM‐H2O structure establishes a robust hydrogen bonding network that stabilizes the triplet excited states, thereby suppressing non‐radiative transitions and extending the phosphorescence lifetime to 904 ± 45 ms. In contrast, DMSO molecules in the HOC‐PM‐DMSO structure promote the separation of aggregate states, leading to a transition in phosphorescence from yellow‐green to blue with a quantum yield of up to 63%. The RTP performance of HOC‐PM‐H2O and HOC‐PM‐DMSO can be reversibly switched by SHUs. By leveraging the temporal and spatial changes in lifetime and color, an information security system and afterglow displays activated by SHUs are developed. The SHUs‐activated strategy not only provides a robust platform for revealing structure‐property relationships but also offers a novel approach to designing advanced functional materials with specific luminescent properties.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"59 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143782446","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present study, a combined approach focusing on the structure of oxygen sites (face‐shared vs corner‐shared) and B‐site substitution in an ABO3 hexagonal perovskite oxide is investigated. Ru‐substituted SrMnO3 nanoparticles (SrMn1−xRuxO3) efficiently catalyzes the aerobic oxidation of thioanisole to sulfone with high selectivity (>99%) even at 30 °C, which is much lower than the temperatures required for the same reaction catalyzed using previously reported Mn‐ and Ru‐based oxide catalysts (80–150 °C). Only a small amount of Ru incorporation (x = 0.01) substantially enhances its catalytic performance. The present catalyst can be reused five times and applied to the aerobic oxidation of various sulfides to afford the corresponding sulfones. Mechanistic studies reveal a bifunctional property of SrMn1−xRuxO3, where surface lattice oxygen is involved in sulfide oxidation, and the strong adsorption of sulfoxides onto the surfaces contributes to the rapid successive oxidation of sulfoxide. Catalyst reducibility estimations and density functional theory calculations indicate that the intrinsic role of Ru is likely to enhance the oxygen transferability of face‐shared Mn4+–O–Mn4+ species.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"89 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143782451","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By utilizing directional airflow during hydrogel drying in combination with rapid photochemistry, protein molecules align efficiently in a single direction. Similar to natural muscle, the mechanical properties of these materials can be further enhanced through mechanical training, achieving remarkable mechanical strength of up to ≈8 MPa at 600% strain and an anisotropy factor of 3.0.

Notably, these anisotropic protein materials exhibit biomimetic rapid actuation (≈6 s) and adaptability under complex physiological conditions. Their potential is demonstrated with proof-of-concept applications as artificial grippers and vessel dilators, which remain stable for months but degrade rapidly within hours after enzymatic treatment post-therapy.
