However, existing electromagnetic wave (EMW) absorbers lack one or more of these key attributes. Herein, we present an EMW absorber that combines ultratransparency (94%), high stretchability (824% fracture strain), and remarkable mechanical and environmental durability. This breakthrough is enabled by a phase-separated terpolymer ionogel. Its effective absorption bandwidth (EAB) of 7.85 GHz in the X and Ku bands significantly outperforms that of all other gel-based materials (&lt;6 GHz) and ranks among the best of all absorbers, whether transparent, stretchable, or neither. This ionogel also demonstrates long-term stability alongside other fascinating properties such as hydrophobicity, skin-like modulus, fatigue and puncture resistance, ability to self-clean, and anti-freezing/icing capabilities. These findings add a key element to the palette, paving the way for next-generation transparent, stretchable devices and ionotronics.","PeriodicalId":388,"journal":{"name":"Matter","volume":"34 1","pages":""},"PeriodicalIF":18.9,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143026845","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}

This work investigates the effects of inhomogeneous stack pressure on Li plating and stripping at the interface between a Li<sub>6</sub>PS<sub>5</sub>Cl solid electrolyte and copper current collector. Elastomeric interlayers are shown to promote a uniform pressure distribution, which can compensate for interfacial roughness and/or misalignment of the external plates used to apply stack pressure. Owing to the improved pressure uniformity, the Li plating coverage increases from 49% to 70% after charging to 2 mAh/cm<sup>2</sup>, and Coulombic efficiency increases from 89% to 94%. The interfacial stress distribution is quantified using finite-element simulations under different interlayer conditions. This work demonstrates that stack pressure should not be defined as a singular quantity but as a parameter that varies in space and time as cycling evolves. This highlights the importance of packaging and component design for SSBs.","PeriodicalId":388,"journal":{"name":"Matter","volume":"18 1","pages":""},"PeriodicalIF":18.9,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143020943","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 introduce a ligand-mediated acid-activatable MPI probe (LAMP) composed of magnetic nanoparticles linked via acid-sensitive imine bond-containing ligands. The LAMP exhibits stable assembly in neutral conditions and rapid disassembly in acidic microenvironments. The imine bond crosslinking promotes a compact structure that enhances magnetic dipole interactions, significantly quenching the initial MPI signal. Upon exposure to acidic conditions, the probe disassembles, restoring the MPI signal in a highly controlled, environment-dependent manner. This switchable assembly enables precise, real-time imaging of acidity-associated diseases such as sepsis progression. Our findings demonstrate that the ligand-mediated modulation of magnetic dipole interactions provides a versatile platform for the design of next-generation MPI probes for biomarker-specific MPI imaging.","PeriodicalId":388,"journal":{"name":"Matter","volume":"74 1","pages":""},"PeriodicalIF":18.9,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143020944","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}
