However, in conventional solid-state regeneration, limited solid–solid contact and the premature formation of a dense conductive carbon layer hinder the effective coordination of lithium replenishment, structural defect repair, and interfacial reconstruction, thereby limiting lithium utilization efficiency and structural restoration. This paper presents a self-assembled supramolecular (SAS) regeneration system spontaneously formed from trithiocyanuric acid (TMT) and lithium acetate (CH3COOLi). Through Li–S coordination and hydrogen-bonding interactions, the precursor self-assembles into an ordered supramolecular architecture that regulates the thermal evolution of the solid-state regeneration process. Unlike the independent thermal decomposition of mechanically mixed precursors in conventional solid-state regeneration, the ordered supramolecular architecture regulates the reaction sequence, enabling lithium to preferentially enter the LiFePO4 lattice before the formation of a dense conductive carbon layer, thereby achieving efficient lithium replenishment and structural restoration. Subsequently, an in situ generated N/S co-doped conductive carbon layer elevates interfacial conductivity of regenerated LFP. The regenerated cathode delivers 160.3 mAh g−1 (0.1 C) and 143.0 mAh g−1 (1 C), maintaining 88% capacity over 500 cycles at 1 C, while the pouch cell exhibits 81% capacity retention after 500 cycles at 0.5 C.\u0000 </div>","PeriodicalId":7803,"journal":{"name":"Angewandte Chemie","volume":"138 43","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149219571","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Microbial sensors offer a promising alternative but suffer from limited specificity, insufficient stability, and slow kinetics. Herein, we report a programmable and printable microbial bioelectronic sensor that overcomes these bottlenecks through multi-scale chemical design. Using 2,4-dinitrotoluene as a model pollutant, we genetically reprogrammed the extracellular electron transfer pathway of Shewanella oneidensis by coupling specific pollutant recognition to inner-membrane cytochrome expression, thereby enabling highly specific bioelectrical detection of target pollutants. For robust deployment, these sensing microbes were encapsulated into a dual-network hydrogel sustained by reversible hydrogen bonding, ensuring structural resilience and biocompatibility. By 3D-printing the biosensor into a biomimetic fractal architecture, we minimized mass transport resistance, achieving a response time of 5 min, a 24-fold acceleration over conventional counterparts. The biosensor also exhibited a low detection limit of 6.75 µg L−1 and a broad dynamic range from 20.4 to 700.0 µg L−1 (R2 > 0.999). Crucially, the biosensor maintained high accuracy (relative error < 4.2%) in actual wastewaters.

Here, we report a metal- and light-free radical sulfinamidation of alkenes that proceeds through a radical chain mechanism enabled by a proton-coupled electron transfer–hydrogen atom transfer (PCET–HAT) relay, initiated by trace amounts of oxygen. This transformation operates under operationally simple conditions, enabling rapid access to structurally diverse sulfinamides with broad substrate scope and excellent functional group tolerance. The synthetic utility of this strategy is demonstrated by the late-stage functionalization of complex natural products and drug molecules. Mechanistic investigations combining experimental studies and density functional theory calculations reveal a PCET-initiated radical chain process in which a HAT event relays reactivity to generate sulfinyl radicals, accounting for the high efficiency and selectivity of the reaction. This work establishes a mechanistically distinct platform for alkene sulfinamidation and highlights the potential of radical chain processes enabled by PCET–HAT relays in synthetic chemistry.\u0000 </div>","PeriodicalId":7803,"journal":{"name":"Angewandte Chemie","volume":"138 43","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149219501","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we propose an enthalpy-entropy molecular design strategy to integrate these processes into a unified electrolyte system. By regulating the solvation structures of Li+ and polysulfides, we can both restrict available reaction pathways and control the coordination environment of polysulfides within the solvation structure. By modulating the solvation structure, we reduce the desolvation enthalpy of both Li+ and polysulfides, thereby promoting uniform nucleation of Li2S. This pioneering design enables the resulting GPE with an ionic conductivity of up to 1.21 mS cm−1 at 22°C and a Li+ transference number of 0.82, the resulting Li||Li symmetric cell can cycle stably for over 2250 h. Consequently, the cell exhibits an ultralow capacity fading rate of 0.043% per cycle over 1000 cycles at 2C and remained functional when assembled into a 1.8 Ah pouch-cell (403.7 Wh kg−1).

Rather than focusing primarily on material-performance advances in the appealing Zn-MnO2 batteries, this review develops a thermodynamic framework for understanding MnO2/Mn2+ conversion chemistry. It emphasizes the fundamental thermodynamic principles governing MnO2/Mn2+ reaction–pathway selection, interfacial evolution, and failure mechanisms.
