Here, we demonstrate that axial coordination of benzotriazole (BTA) to Ni single atoms in C 3 N 4 (BTA‐Ni SAs‐C 3 N 4 ) facilitates interfacial electron‐transfer processes. Femtosecond transient absorption spectroscopy, in situ transient surface photovoltage spectroscopy, in situ photochemical infrared spectroscopy, and theoretical simulations reveal that BTA‐coordinated Ni SAs serve as the centers for rapid electron transfer by upshifting the Ni d‐band center and strengthening the orbital overlap between Ni SA and adsorbed C 2 H 2 . Consequently, BTA‐Ni SAs‐C 3 N 4 achieves a very high C 2 H 4 production rate of 32.29 mmol g cat −1 h −1 with a C 2 H 4 selectivity of 97.6% under simulated solar irradiation, which is ∼4‐times higher than that for Ni SAs‐C 3 N 4 . The apparent quantum yield at 365 nm is up to 4.65%, superior to reported photocatalytic acetylene semi‐hydrogenation. This work highlights the importance of interfacial charge transfer in photocatalytic acetylene hydrogenation and provides a rational strategy for designing high‐performance photocatalysts.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"11 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149173011","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 review provides a comprehensive overview of bio‐integrated edge computing systems for smart and connected health, focusing on the co‐design of computing, sensing, and energy strategies. We first examine computing approaches, including conventional von Neumann architectures and emerging paradigms such as compute‐in‐memory and neuromorphic systems, for on‐device data processing and decision‐making. We then discuss sensing strategies that enhance signal fidelity and enable efficient information representation at the biointerface. Finally, we review energy solutions that enable continuous, autonomous operation.

Here, we integrate the layered Hofmann‐type spin‐crossover (SCO) MOF {Fe II (pyS 2 Et) 2 [Pt II (CN) 4 ]} into electrical nanodevices to control the properties of two‐dimensional (2D) quantum materials. Our molecular approach exploits the stimuli‐responsive nature of SCO‐layered materials as switchable building blocks. We demonstrate selective modulation of the electronic transport in van der Waals heterostructures interfacing SCO with 2D quantum materials (few‐layer graphene, magnetic CrSBr, superconducting NbSe 2 ) through the strain induced via thermal and light‐induced spin transitions. In graphene, the conductivity is selectively switched by light. In spin‐valves based on CrSBr bilayers, the MOF triggers magnetic hysteresis (absent in pristine CrSBr) and enables tunable non‐volatile zero‐field memory. In NbSe 2 , light modulates the superconducting critical current and transition temperature. These results establish layered stimuli‐responsive SCO MOFs as active molecular control elements for 2D quantum materials, providing a route to strain‐mediated control of electronic, magnetic, and superconducting functionalities, and extending MOF‐based architectures beyond traditional porous‐matter applications toward multifunctional electronics and spintronics.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"1 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149172884","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}

A solvation‐equilibrium‐locked electrolyte (SELE) is reported by combining dimethyl sulfite (DMS), a low‐freezing weakly solvating solvent, with Pyr 13 DFOB (1‐methyl‐1‐propylpyrrolidinium difluoro(oxalato)borate) as an ionic‐liquid co‐solvent. Cooperative ion–dipole and weak C–H⋯O interactions between DMS and Pyr 13 + regulate the free‐solvent reservoir, while TFSI − (bis(trifluoromethanesulfonyl)imide) and DFOB − enrich the primary Li + coordination shell. Variable‐temperature 7 Li NMR, Raman, and molecular dynamics simulations show that solvent‐separated ion pairs, contact ion pairs, and aggregates remain nearly invariant from −60°C to 60°C, unlike the strongly temperature‐responsive Pyr 13 DFOB‐free electrolyte. This locked anion‐rich solvation structure reduces solvent coordination around Li + , mitigates solvent‐derived interfacial decomposition and gas evolution, and promotes LiF‐ and borate‐rich interphases on Li metal and NMC811. Consequently, Li||NMC811 cells deliver discharge capacity at −85°C and operate up to 120°C, while pouch cells remain functional after cooling to −122.9°C. A 6.6 Ah Li||Ni90 pouch cell further achieves 565 Wh kg −1 under lean‐electrolyte conditions, establishing solvation‐equilibrium locking as a molecular design principle for lithium metal batteries operating over a broad temperature range.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"53 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149172887","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}

Herein, we propose a stepwise cyanation strategy to modify quinoxaline‐based polymeric semiconductors to mitigate this dilemma. Benefiting from the strong electron‐withdrawing ability of cyano substituents, QxCN‐CNTVT functionalized with cyano groups on both donor and acceptor units exhibits a deep LUMO level of −4.23 eV, one of the deepest among reported n ‐type ionic–electronic conductors. As a result, OECTs based on QxCN‐CNTVT demonstrate excellent comprehensive performance, with a high µC* value of up to 168.89 F cm −1 V −1 s −1 and a low V th of 0.13 V, while maintaining superior operational stability (retaining ∼80% of the initial current after 10,000 s of continuous operation and 10,000 full switching cycles). Furthermore, QxCN‐CNTVT is successfully applied to complementary inverters for efficient amplification of electrooculogram (EOG) and electrocardiogram (ECG) signals, as well as NAND and NOR logic gates for integrated logic functions. This work not only alleviates the widely observed imbalance between performance and V th in n ‐type OECTs but also provides a versatile molecular design strategy for next‐generation low‐power bioelectronic devices.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"10 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149172881","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}

Herein, we report a general long‐range electronic structure regulation strategy to construct ultrafine rare‐earth oxide clusters anchored proximal to Zn single‐atom sites (LaO x ‐Zn‐SA/CNCl), aiming at boosting ORR activity. Benefiting from the tailored long‐range electronic modulation by LaO x clusters and the hierarchical porous carbon support that maximizes Zn atom utilization, the catalysts exhibit a high half‐wave potential of 0.90 V along with remarkable stability in alkaline media. This represents a non‐precious‐metal, rare‐earth‐based electrocatalyst among the best reported so far. A zinc–air battery (ZAB) integrating LaO x ‐Zn‐SA/CNCl as the cathode catalyst delivers a maximum power density of 177.3 mW cm −2 at 225 mA cm −2 . Theoretical calculations reveal that the proximal LaO x clusters remotely modulate the electronic structures of Zn sites, enhancing electron‐transfer efficiency by strengthening electronic interactions. With the optimized electronic state of Zn sites, the adsorption of key intermediates is balanced to alleviate the energy barriers of the rate‐determining step. This work provides insights into the long‐range electronic regulation of transition‐metal single‐atom sites within a hierarchical rare‐earth cluster‐coupled microenvironment for efficient electrocatalysis.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"13 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149172853","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}

However, voltage hysteresis exceeding 1 V, especially during the first cycle, remains a long‐standing and unresolved challenge, severely limiting energy efficiency and practical deployment. Here, we propose a quasi‐flat‐band framework in which oxygen 2p states near the Fermi level are intrinsically sensitive to perturbations. Even weak perturbations, such as minor lattice distortions during delithiation or thermal vibrations at room temperature, can disproportionately amplify band dispersion and induce hysteresis. This insight reframes the long‐standing design strategy by extending it beyond suppressing structural reconstructions to include control of perturbation‐driven electronic instability. Future materials design should pursue two principles: stabilizing symmetry to sustain quasi‐flat‐band characteristics and engineering orbital hybridization to enhance their robustness against perturbations. This work rethinks the origin and mitigation of voltage hysteresis, bringing oxygen‐redox cathodes closer to reliable operation at high voltages.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"30 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149173008","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}

TBBP exhibits excellent photostability, broadband second near‐infrared (1000–1600 nm) emission, and efficient photothermal conversion (42.17%). Supramolecular assembly with DSPE‐PEG2000 affords stable TBBP nanomicelles, TBBP NPs, that selectively generate superoxide radicals (O 2 −• ) and retain potent Type I photodynamic therapy (PDT) activity under hypoxia. Photoactivated TBBP NPs further induce mitochondrial dysfunction and caspase‐3/GSDME‐mediated immunogenic pyroptosis, promoting dendritic cell maturation and CD8 + T cell infiltration. In a bilateral 4T1 tumor model, TBBP NPs enable high‐contrast second near‐infrared (NIR‐II) imaging, while synergistic Type I PDT and photothermal therapy elicit systemic antitumor immunity, achieving 92.0% primary tumor inhibition and 47.7% distant tumor inhibition.
