Results show that the SIFMF‐NPS involves interfacial swelling and interdiffusion, nanophase separation, and interfacial co‐crystallization. Consequently, it establishes a remarkably enhanced interfacial strength (119 ± 7.6 MPa, ≈100 times greater than its counterpart), an exceptional toughness of 377 ± 4.6 MJ m−2 (about three times that of its control sample), as well as valuable functions including high‐performance triboelectricity, motion sensitivity, and advanced thermal insulation.

This work proposes a systematic strategy integrating catalytic site exposure, intrinsic activity, and Li2S deposition mode design by combining orbital‐transmission and defect engineering. The defect‐engineered MoS2 nanosheets featuring interfacial Mo‐N‐C coordination bonds are vertically aligned into ordered arrays within the nanochannels of a conductive membrane. This design maximizes the utilization of active sites, enlarges the three‐phase interface, and enhances electron and mass transport, thus promoting a continuous adsorption‐catalysis‐deposition process. Both experiments and theoretical calculations demonstrate that the altered electronic structure around the microporous defects transforms the conventional 2D Li2S deposition mode into a 3D growth mode, thereby enhancing the overall reversibility and reaction kinetics. The transformation originates from changes in electronic occupancy, altering the orientation of atomic orbitals and increasing the orbital overlap between different atoms. Notably, this effect can even propagate Li2S molecules far from the catalyst surface. The cell delivers outstanding cycling performance with an average capacity decay of only 0.048% per cycle over 1000 cycles at 2C. Moreover, with a high sulfur loading of 6.75 mg cm−2 and a low electrolyte/sulfur ratio (6.55 µL mg−1), an impressive areal capacity of 7.38 mAh cm−2 is achieved.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"3 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145035761","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}

Dentin degradation poses a significant clinical burden, as exposed dentinal tubules serve as direct pathways for irritants and pathogens, triggering pain, inflammation, and irreversible pulp damage. Although biomimetic mineralization holds great promise for dentin regeneration, its clinical translation remains hindered by ineffective mineralization templates due to collagen degradation, poor mineral precursor delivery, and insufficient dentin–pulp complex restoration. Inspired by natural biomineralization, a biomimetic DentinLayer is constructed by photo‐crosslinking methacrylated type I collagen (ColMA) with methacrylated polyacrylic acid‐stabilized amorphous calcium phosphate (PMA@ACP), forming a composite hydrogel (ColPMA@ACP) that induces spontaneous intrafibrillar mineralization of both native and applied collagen. Both in vitro and in vivo studies confirm that ColPMA@ACP facilitates rapid collagen mineralization, effectively occludes dentinal tubules, restores dentin mechanical integrity, and creates a favorable microenvironment that supports reparative dentin formation and attenuates pain‐related neural signaling. This multifunctional biomimetic DentinLayer offers a minimally invasive, clinically translatable strategy that integrates structural reconstruction, mineralization templating, and autonomous mineralization to effectively restore the structure, function, and bioactivity of dentin. It provides a new approach for dentin defect repair and offers a versatile framework for the development of bioinspired materials in regenerative dentistry.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"16 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145035784","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}

Beginning with fundamental concepts of AI/ML in energy storage, the analysis progresses to comprehensive applications in LIBs technology. Meanwhile, AI‐driven approaches enhance discovery efficiency for electrode materials, while improving property prediction accuracy and cost‐effectiveness. For materials synthesis, AI enables parameter optimization across scales and facilitates transition from lab‐scale breakthroughs to industrial production. Within electrode manufacturing, AI applications evolve from localized process optimization toward integrated full‐chain modeling and closed‐loop control systems. In cell manufacturing, AI demonstrates particular promise in three key areas, while showing limitations in whole‐process reliability forecasting.

Oxygen layered reconfiguration strategy toward P2‐typed Na0.75[Ni0.3Mn0.5Cu0.1Ti0.05Mo0.05]O2 is thus utilized to realize a twin structure to achieve high energy density and high reversibility with long cycling lifespan. Under high‐voltage conditions, the introduction of twin boundaries with symmetrical ‘ABAB’ oxygen atom arrangement can modulate the local bonding environment by shortening TM─O bond lengths and enhancing the orbital hybridization, which collectively reinforce Mn─O covalency and stabilize lattice oxygen. The simultaneously reduced oxygen anion charge density and expanded interlayer spacing can effectively alleviate interlayer electrostatic repulsion, thereby suppressing the irreversible P to O‐type layers transition. Meanwhile, the overlap of the valence and conduction bands at the Fermi level induced by the twin structure leads to an interfacial semi‐metallic behavior along the ion transport pathways and consequently enhances the bulk electronic conductivity.

However, conventional transition metal–organic frameworks (MOFs) primarily induce radical‐based processes, limiting their stability and selectivity under complex water matrices. A series of KNbO3/ZIF‐67(Co) heterojunctions (K@Z‐x) with interfacial Co─O─Nb bonds is constructed via piezoelectric polarization engineering. This unique bonding microenvironment reconfigures the electron density of Co(II) sites and optimizes PMS adsorption configurations. Co─O─Nb bridging shifts PMS activation from radical (•OH and SO4•−) to dual non‐radical pathways, enabling simultaneous generation of singlet oxygen (1O2) and high‐valent cobalt‐oxo (Co(IV)═O) species. Theoretical calculations reveal reduced energy barriers for *SO5─H formation and enhance electron delocalization at the heterointerface. Visible light and ultrasound co‐irradiations accelerate Co(III)/Co(II) cycling via piezoelectric field‐enhanced carrier separation, sustaining Co(IV)═O generation. The optimized K@Z‐2/PMS/Vis/US system achieves near‐complete tetracycline degradation within 1 min, with excellent selectivity, stability, and environmental tolerance. Toxicity evaluation confirms its low ecotoxicity, while life cycle assessment highlights its reduced energy consumption and environmental burden.
