However, they still face the challenge of balancing mechanical properties and thermal insulation to fully realize their potential. Here, we report a wet-freeze spinning technique for the continuous, large-scale preparation of dense skin-porous core-structured polyimide aerogel fibers. The unique multiscale structural design, which includes a highly oriented dense skin layer to withstand load stresses and a porous core to impede heat transfer, achieves exceptionally high strength and low thermal conductivity. The resulting robust skin-core polyimide (SCPI) aerogel fibers exhibit ultrahigh specific strength up to 775.8 MPa cm3 g−1, much higher than previously reported aerogel fibers. Moreover, the obtained aerogel fabrics demonstrate excellent thermal insulation properties (30.4 mW m−1 K−1) under long-term thermal shock. This strategy offers a universal and continuous way to prepare high-strength aerogel fibers and is crucial for promoting the fiber industry.","PeriodicalId":388,"journal":{"name":"Matter","volume":"54 1","pages":""},"PeriodicalIF":18.9,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144088008","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}

To address this issue, we engineered an oxygen vacancy-driven nanopump for I2 molecules based on a two-dimensional van der Waals heterostructure, comprising oxygen vacancy-rich Ti-Nb bimetallic oxide nanosheets sandwiched between carbon layers (Vo-TNO@C). The oxygen vacancies in Vo-TNO@C strongly interact with I2, facilitating effective capture and confinement of I2 within the interlayer gap. The confined I2 is catalytically transformed in situ by the oxygen vacancies, altering the reaction pathway from the conventional approach (I2 → I3− → I−) to a more efficient way (I2 → I−). This confined catalysis significantly accelerates conversion kinetics and suppresses polyiodide formation, resulting in shuttle-free Zn-I2 batteries with an exceptional lifespan exceeding 70,000 cycles.","PeriodicalId":388,"journal":{"name":"Matter","volume":"1 1","pages":""},"PeriodicalIF":18.9,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143980169","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}

These materials consist of alternating layers of organic cations and inorganic octahedra. The organic cations often undergo order-to-disorder phase transitions near room temperature, leading to subtle changes in the inorganic layer that impact their optoelectronic properties. To elucidate how structural changes influence optoelectronic properties, we interrogate a series of 2D lead bromide and iodide perovskites with different-length alkylammonium cations. We find that the octahedra become either more or less distorted at the phase transition temperature, depending on the identity of the cation and halide, and that octahedral motion occurs either continuously with temperature or abruptly across a phase transition. Our study directly links structural dynamics to reversible changes in the optical properties of 2D perovskites and realizes the potential for dynamically switchable optoelectronics with hybrid materials.","PeriodicalId":388,"journal":{"name":"Matter","volume":"17 1","pages":""},"PeriodicalIF":18.9,"publicationDate":"2025-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143933555","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}
