However, due to the limited dissociation of Li salts in SPEs, the native solid electrolyte interphase (SEI) typically manifests insufficient inorganic constituents, leading to sluggish and heterogeneous Li‐ion transport kinetics. Herein, the dissociation of Li salts is significantly enhanced by deep eutectic interaction between 1,3‐dimethylurea (DMU) molecules and lithium bis(trifluoromethanesulphonyl)imide (LiTFSI), which constructs a Li2S and LiF‐rich SEI. The resultant SEI demonstrates remarkably enhanced Li‐ion transport kinetics and stability, enabling an impressive performance of 2900 h in symmetrical cells. Moreover, the all‐solid‐state LiFePO4 | Li cells benefiting from the Li2S and LiF‐rich SEI maintain 80% capacity retention over 700 cycles and demonstrate a high specific capacity of 91 mA h g−1 after 1000 cycles at a high rate of 1.0 C. This study provides a simple and accessible method to enhance the dissociation of Li salt by deep eutectic interactions, which assists in constructing an inorganic‐rich SEI and achieves performance improvement of all‐solid‐state Li metal batteries.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"13 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145002791","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}

Nevertheless, they remain distant from practical application owing to the insufficient comprehension of the interactions between these two components and the intricacies involved in their preparation process. In this context, a novel hybrid heterostructure made of a contorted tetra-benzo-furanyl-benzo-coronene (cTBFBC) and a SnS2 nanoarchitecture is synthesized to create high-efficiency hybrid photocatalysts. The cTBFBC with coronene linked with benzo-furanyl side chains not only promotes ion uptake and transport but also enhances interaction with SnS2. The photophysical investigations utilizing photoluminescence, absorption spectroscopy, EIS, UPS, and Mott–Schottky analyses revealed that the close contact between cTBFBC and SnS2 suppresses the charge-transfer resistance at the interface and provides a dual Z-scheme charge transfer mechanism at the heterojunction interface. The developed hybrid photocatalyst achieves a notable hydrogen evolution rate of 1510 μmol.g-1.h-1, which is 7 times greater than that of SnS2 and 12 times higher than that of cTBFBC nanoparticles. This research highlights the promising potential of cTBFBC in the development of hybrid heterojunctions for photocatalytic hydrogen production, presenting a comprehensive understanding of the high photocatalytic performance exhibited by such heterojunction photocatalysts.","PeriodicalId":344,"journal":{"name":"Journal of Alloys and Compounds","volume":"16 1","pages":""},"PeriodicalIF":6.2,"publicationDate":"2025-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145003437","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In continuous production systems, immobilized enzymes are required as catalysts, and providing them in a carrier‐free form is preferable to maximize effective reactor space usage. This study explores the use of non‐covalent protein interaction domains for fabricating catalytically active all‐enzyme hydrogel (AEH) materials. For this, enzymes of a binary interacting cascade – an alcohol dehydrogenase and a glucose‐1‐dehydrogenase for cofactor regeneration – are genetically fused to various non‐covalent binding motifs (PDZ, GBD, SH3), enabling self‐assembly into non‐covalent AEHs. The resulting materials are generated both in living E. coli cells and from purified enzymes as monodisperse enzyme foams. While in‐cell AEHs show no significant advantages over non‐assembled cascades in continuous flow reactors, the AEH foams demonstrated excellent performance. Optimized systems based on SH3 and PDZ domains, despite a 100‐fold difference in binding affinity, achieved stable conversions above 70% over 30 h. Notably, drying the enzyme foams significantly improved both mechanical stability and catalytic activity. The successful application of this approach to a different enzyme system based on phenolic acid decarboxylase further underscores its versatility and suitability for developing robust biocatalytic materials for sustainable industrial processes.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"14 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145002931","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}

BPA-F and DOTA-Gd were coloaded into lipid nanocarriers using a microfluidic system, with Angiopep-2 modification to enhance blood-brain barrier penetration and glioma targeting. Following cellular uptake, BPA-F&DOTA-Gd@LIPO-ANG effectively increased boron accumulation in glioma cells, inducing significant apoptosis and DNA damage upon neutron irradiation. Intravenously injected into orthotopic glioma model mice, BPA-F&DOTA-Gd@LIPO-ANG selectively accumulated in the tumor site, increasing tumor-to-normal tissue (T/N) and tumor-to-blood (T/B) ratios. Enhanced boron accumulation facilitated greater cytotoxic effects mediated by high-energy rays from the boron capture reaction, leading to significantly prolonged mice survival. In addition, in vitro and in vivo MRI validations confirmed its MRI visualization capability, meeting the demand for boron drug imaging for BNCT diagnosis and treatment integration.

These SS-HPT/siRMMP-9 complexes are incorporated into a hyaluronic acid-based hydrogel with redox-responsive properties (OR-S gel), allowing dual regulation of reactive oxygen species (ROS) in the wound microenvironment. The hydrogel network actively scavenges excess ROS, mitigating oxidative stress damage to tissue repair. Simultaneously, ROS-mediated hydrogel degradation enables the controlled release of siRMMP-9, enhancing the treatment's spatiotemporal precision and biocompatibility. In vitro and in vivo experiments confirm that this treatment system effectively down-regulates MMP-9 expression, remodels the extracellular matrix, and enhances the wound repair microenvironment, thereby significantly accelerating the healing of chronic diabetic wounds.

Sb2Se3 absorbers are fabricated through sputtering-based Sb deposition followed by post-selenization at ramping rates of 40 and 60 °C/min. Faster temperature ramping (60 °C/min) promotes rapid grain growth, yielding a dominant [002] and [hkl] (l ≠ 0) crystal direction, which enhances the carrier transport along the (Sb4Se6)n ribbons. This preferential direction reduces the defect density and improves key device metrics, including the photovoltaic conversion efficiency, open-circuit voltage, current density, fill factor, and carrier lifetime. In contrast, slower ramping (40 °C/min) yields a more random crystal direction and higher defect density, adversely affecting the device performance. Comprehensive characterization via SEM, XRD, UPS, admittance spectroscopy, and STEM-EDS supports these findings and reveals that variations in the Se/Sb ratio influence the defect formation.
