Despite notable advances in accelerating ion/electron transport, intrinsically reducing the large reaction kinetic barrier and activation energy associated with robust metal–chalcogen (M─S) bonds remains a long‐standing challenge. In this study, we propose a universal spin‐polarization‐engineered (SPE) antibonding‐orbital modulation paradigm to fundamentally regulate M─S bond strength and enable ultrahigh‐rate sodium storage. As a proof of concept, magnetic manganese heteroatom doping into heterojunctions enhances the saturation magnetization by ∼210%, inducing a spin‐state transition from low‐spin to high‐spin configurations, which increases the electron occupation of antibonding orbitals formed between metal e g orbitals and chalcogen p orbitals, and thereby regulates M─S bond strength. Benefiting from this spin‐engineered electronic reconstruction, Mn‐FeS 2 /CoS 2 anode delivers an ultrahigh‐rate capability of 300 mA h g −1 at 120 A g −1 , together with exceptional long‐term durability (∼100% retention over 13 000 cycles at 100 A g −1 ), ranking among the best record. The generality of this strategy is further validated by extending SPE modulation to other magnetic dopants. Moreover, the industrial‐level pouch cell is assembled to demonstrate the practical potential of this strategy.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"11 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2026-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149172722","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}

Yet mRNA delivery remains centered on intramuscular vaccination and intravenous administration, largely optimized for systemic adaptive immunity or circulation‐mediated biodistribution. Many localized diseases, however, are confined to tissues or compartments accessible by topical, transdermal, inhaled, oral, catheter‐based, ocular, or intra‐articular administration without initial reliance on circulation. For these diseases, the therapeutic objective is likewise local: therapeutically relevant mRNA expression occurs within the affected tissue, and efficacy derives predominantly from the local biological activity of the encoded protein rather than from downstream systemic effects initiated by local expression. This therapeutic paradigm is defined here as Anatomically Accessible Local mRNA Therapeutics (ALmT). The review first distinguishes ALmT from intravenous mRNA delivery and intramuscular mRNA vaccination, then organizes site‐specific barriers and engineering strategies across major anatomical sites. It further examines disease‐focused ALmT applications, highlighting protein restoration, cytokine or growth‐factor supplementation, local antibody‐fragment production, regenerative modulation, and tissue repair. Finally, it discusses general design principles, quantitative PK/PD evaluation, repeat‐dose safety, and clinical translation. Overall, the ALmT framework may facilitate the design, quantitative evaluation, and clinical translation of mRNA therapies for localized diseases.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"11 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2026-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149172678","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}

Despite extensive efforts in facet engineering, achieving homogeneous Li deposition on practical polycrystalline Cu collectors remains elusive, highlighting an incomplete understanding of the structural factors governing Li deposition. Herein, a defect‐mediated interfacial engineering strategy is developed by simultaneously introducing a high density of geometrically necessary dislocations (GNDs) and enriched <110>/<111> textures on commercial electrodeposited Cu foils. Theoretical calculations and experiments reveal that densely distributed dislocations provide thermodynamically favorable Li adsorption sites and abundant preferential heterogeneous nucleation sites, while the enriched <110>/<111> textures promote Li surface diffusion and lateral growth. This combined effect promotes uniform and compact initial Li deposition, guiding path‐dependent deposition evolution and suppressing interfacial heterogeneity. The control experiments further support a key contribution of dislocation defects, while variations in surface chemistry or morphology alone cannot account for the observed performance differences. The optimized Cu foil sustains over 1200 cycles with an average Coulombic efficiency of 99.52% ± 0.20% over the final 200 cycles ( n = 4) in Li||Cu cells and improves N/P = 0 Cu||NCM811 full‐cell cycling.

Despite extensive efforts, the concurrent chip‐scale realization of nonlinear frequency conversion and fast temporal gating for high‐fidelity quantum control has remained elusive. Here, we demonstrate a monolithic thin‐film lithium niobate (TFLN) platform integrating periodically poled frequency conversion with GHz‐bandwidth electro‐optic (EO) switching. The device delivers off‐chip green‐light power exceeding 1 mW with an extinction ratio (ER) of 42.2 dB, enabling coherent spin control and time‐resolved lifetime measurements of individual nitrogen‐vacancy (NV) centers in diamond through nanosecond gating. System performance is validated through pulsed optically detected magnetic resonance (ODMR), Rabi oscillations, and Ramsey interference, supported by time‐tagged photon counting with nanosecond resolution. By unifying sufficient nonlinear light generation with high‐speed active manipulation, this platform establishes a scalable framework for the realization of high‐rate quantum communication nodes.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"14 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2026-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149172723","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 report a lutetium‐stabilized cobalt oxide catalyst (Lu 0.08 Co 2.92 O 4 ) designed through site‐specific electronic modulation, achieving a synergistic enhancement of both activity and stability in acidic OER for proton exchange membrane water electrolyzers (PEMWEs). Operando spectroscopies combined with theoretical simulations reveal that Lu incorporation introduces robust Lu‐O bonds and induces charge redistribution that strengthens Co‐O covalency and suppresses Co 2+ dissolution, which is critical for improved OER durability, and simultaneously optimizes the Co‐Co distance to favor direct O‐O radical coupling with a reduced energy barrier. Leveraging these structural advantages, a practical PEMWE employing Lu 0.08 Co 2.92 O 4 delivers an industrially relevant current density of 1000 mA cm −2 at 1.837 V.

While persistent charge availability post-light cutoff is central to dark-state catalysis, a quantitative structure-dynamics-function relationship linking molecular design to charge-retention kinetics and post-illumination reactivity remains unestablished. Here, we report a molecular tuning strategy of the central amine-derived units that systematically regulates charge separation, retention timescales, and dark-state H2O2 production in imine-linked polymer networks. Systematic evaluation of the series reveals a direct correlation between charge lifetime and dark activity. Compared with the N-centered reference, the C3N3-centered analogue exhibits drastically prolonged electron-associated transient lifetime, with a ∼27-fold longer decay timescale at the picosecond scale and a ∼3-fold increase at the nanosecond scale. This enhanced charge retention corresponds to a dark-state H2O2 production of 4941 µmol g-1 within 40 min, ∼1.5-fold higher than that of the N-centered counterpart. Density functional theory calculations reveal distinct electronic structures associated within the C3N3-centered framework, providing a favorable electronic environment for electron localization and subsequent utilization. These results establish a molecular structure-charge retention-dark reaction relationship for photocatalytic H2O2 production beyond the illumination period.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":" ","pages":"e75402"},"PeriodicalIF":29.1,"publicationDate":"2026-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149163604","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}

In nanostructures with nanometer-scale curvature, bending can perturb out-of-plane π orbitals and generate quantum-mechanical polarization and electrostatic modulation beyond classical lattice distortion alone. Here, we combine scanning probe measurements and first-principles calculations to provide experimental and theoretical evidence for large intrinsic quantum orbital flexoelectricity in graphene nanowrinkles (GNWrs) with estimated polarization densities of Pth ∼ 4 C m−2 and Pexp ∼ 1 C m−2, exceeding those of mesoscale systems by 5 to 7 orders of magnitude. These GNWrs exhibit high apex curvature, undergo atomic-level buckling, and produce localized strain fields, as supported by atomic force microscopy analysis and Raman spectroscopy. Kelvin probe force microscopy reveals curvature-dependent work-function shifts, while conductive atomic force microscopy detects reproducible GNWr-associated currents with a threshold voltage (Φth ∼ 1 V) comparable to the band offset predicted by ab initio calculations (∼ 1.2 V). These results support an interpretation in which curvature-induced flexoelectric dipoles reshape the local electronic potential. GNWrs therefore provide a structurally simple carbon-based platform for probing quantum-mechanical flexoelectricity.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"38 57","pages":""},"PeriodicalIF":29.1,"publicationDate":"2026-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adma.202518224","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148589676","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
