Nevertheless, developing ultrathin SPEs with both high ionic conductivity, and strong Li dendrite retardant is still a significant challenge. Here a scalable fabrication of high-performance ultrathin (≈7.8 µm) polycarbonate-based electrolyte (UPCE) is proposed via electrolyte structural engineering, phase separation-derived poly(vinylidene fluoride-co-hexafluoropropylene) (PVH) porous scaffold, without use of additional liquid additives. The rational electrolyte structural modulation with 1-fluoro-4-(1-methylethenyl)benzene (FMB) enables a weakened Li+-polymer interaction due to weak Li+ solvation with fluorine, benzene ring, facilitates the formation of LiF-rich solid-electrolyte-interphase on Li metal surface. As a result, the designed UPCE delivers a high ionic conductivity of 4.8 × 10-4 S cm-1, an ultrahigh critical current density of 11.5 mA cm-2 at 25 °C. The solid-state Li symmetric cell attains unprecedented ultralong cycling over 6000 h at 0.5 mA cm-2. Furthermore, the Li|LiCoO2 cell cycles stably over 1500 cycles at a high operating voltage of 4.5 V, and the pouch cell can achieve a high energy density of 495 Wh kg-1 excluding the packaging.

Mirroring the anti-reflective coating of insect eyes, where Turing-patterned corneal protrusions form graded refractive index interfaces with the lens, a bioinspired integration of Turing-nanoarchitected Ag (TN-Ag) with in situ zeolitic imidazolate framework-8 (ZIF-8) growth is engineered. The electrochemically sculpted fractal framework on silver needles serves dual roles as plasmonic amplifiers and curvature-guided templates for ZIF-8 growth, spatially aligning electromagnetic hotspots with selective-enrichment porous channels. The TN-Ag/ZIF-8 hierarchical architecture enables dual-scale SERS enhancement through mesoscopic light modulation via refractive index gradients and microscopic molecular enrichment through size-selective pores. Leveraging 4-mercaptophenylboronic acid as a dual-recognition probe, this platform achieves ultrasensitive discrimination and detection of Hg2+ (10-10 m) and methylmercury (10-8 m) with exceptional interference resistance and practical reliability. Further, its injector-integrated design permits direct sampling in untreated solid matrices while seamlessly interfacing with portable Raman systems, demonstrating readiness for real-world environmental monitoring and food safety diagnostics.

Building on this legacy, eutectic high-entropy alloys (EHEAs) have recently emerged to push the boundaries of mechanical performance. However, the strength potential of EHEAs remains largely untapped, primarily because of limitations in cooling rates, posing a significant challenge to the development of ultra-strong bulk EHEAs. This study employs large-scale molecular dynamics simulations to uncover key insights into the design of EHEAs with exceptional mechanical performance. Simulations reveal that the maximum tensile strength occurs at a critical interphase boundary spacing, an order of magnitude larger than that observed in conventional alloys. Below this spacing, the governing mechanism shifts from the Hall-Petch strengthening to dislocation multiplication-mediated softening. Guided by the simulation insights, a tensile strength of 1.8 GPa is achieved for laser powder bed fusion-fabricated EHEAs. This strength approaches the theoretical limit and outperforms other state-of-the-art as-printed high-entropy alloys. This work not only establishes a viable pathway for designing ultra-strong EHEAs but also provides a promising avenue for addressing the long-standing challenge of developing high-performance as-printed materials for aerospace and other demanding applications.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":" ","pages":"e2500149"},"PeriodicalIF":27.4,"publicationDate":"2025-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144504248","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 study presents a novel EVs‐based multiplexed diagnostic model for AD, correctly classifying all clinical samples (n = 40), far exceeding the accuracy of a single biomarker.
