The tissue consists of a soft matrix and crimped fibers. Inspired by this architecture, we develop a composite of a soft polymer matrix and a knitted fabric. When the stretch is small to modest, the knitted fabric is easily stretched, so that the composite is soft. When the stretch is large, the knitted fabric is stiff and strong, so that the composite resists fatigue crack growth. The mechanical behavior of the composite is comparable to that of bovine pericardium. The composite has an exceptionally long fatigue life, enduring 25 million cycles of pulsatile flow, two orders of magnitude longer than the polymer matrix. This soft and fatigue-resistant composite may find broad applications in biomedicine.","PeriodicalId":388,"journal":{"name":"Matter","volume":"8 1","pages":""},"PeriodicalIF":18.9,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142816241","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}

However, determining the surface coverage and distribution of a molecular catalyst on a solid support is often challenging, inhibiting our ability to design improved catalytic systems. Here, we demonstrate that the combination of scanning transmission electron microscopy (STEM) and image analysis of the individual positions of heavy atoms in transition metal complexes via a convolutional neural network (CNN) allows statistically robust determination of the surface coverage and distribution of immobilized molecular catalysts. These observations provide information about how changes in the functionalization conditions, attachment group, and structure of the molecular catalyst affect the surface coverage and distribution, providing insight into the chemical mechanism of surface immobilization. The method could be generally valuable for correlating the surface coverage and distribution to the activity, selectivity, and stability of a catalytic system.","PeriodicalId":388,"journal":{"name":"Matter","volume":"110 19 1","pages":""},"PeriodicalIF":18.9,"publicationDate":"2024-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142793197","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}

However, the compression along which direction stabilizes perovskite remains unclear due to the presence of non-uniform strain within the material. Here, we introduce a metal encapsulation method to apply compressive strain along the in-plane or out-of-plane direction of perovskite film. According to the grazing-incidence wide-angle X-ray scattering (GIWAXS) results, in-plane compression enhances the stability of perovskites, whereas out-of-plane compression has a detrimental effect. Specifically, out-of-plane compression can lead to the formation of an inactive δ-phase, which compromises the stability of the perovskite. Finally, we develop a general process to integrate in-plane compression into perovskite solar cell (PSC) devices, thereby improving their stability. Our study clarifies the mechanism by which compressive strain affects perovskite stability, offering valuable guidance for strain engineering to optimize perovskite performance.","PeriodicalId":388,"journal":{"name":"Matter","volume":"212 1","pages":""},"PeriodicalIF":18.9,"publicationDate":"2024-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142793479","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}

However, a planar junction made of two-dimensional (2D) materials commonly suffers from slow response and irreversible recovery because of slow physisorption and desorption rates. Herein, we present a unique design of a mixed-dimensional heterojunction built from patterned growth of 3D n-type CdS nanowire arrays and p-type 2D WSe<sub>2</sub> nanosheets for photoelectric gas sensors. This heterojunction sensor showed highly selective and reversible responses to NO<sub>2</sub> and NH<sub>3</sub> with detection limits of 60 and 54 ppb, respectively, under UV illumination at room temperature. Notably, the sensor exhibited an ultrafast response time of less than 1 s to 1 ppm NO<sub>2</sub> and NH<sub>3</sub>, which outperforms most previous reports. The hybrid junction structure proposed herein will pave the way for engineering new electronic devices from a broad selection of materials to achieve improved sensing performances at room temperature.","PeriodicalId":388,"journal":{"name":"Matter","volume":"19 1","pages":""},"PeriodicalIF":18.9,"publicationDate":"2024-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142763890","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}

Here, we endeavor to summarize the state-of-the-art achievements in EV-based vaccines, particularly those aimed at immunizing against infectious pathogens and cancers. The emerging strategies for genetically or non-genetically engineering EVs to be loaded with antigenic proteins and antigen-encoding RNAs are highlighted. For each methodology, the rationale underlying its development is elaborated. In addition, EV biogenesis, cargo sorting, and immunomodulatory roles are discussed, as well as the clinical translation, latest industrial pipelines, current challenges, and envisioned directions for EV vaccines. This review may offer insights into the rational design of EVs as a cutting-edge vaccine platform to stimulate potent, broad, and long-lasting immunity.","PeriodicalId":388,"journal":{"name":"Matter","volume":"262 1","pages":""},"PeriodicalIF":18.9,"publicationDate":"2024-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142763901","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}
