However, the interfacial degradation mechanism remains inadequately resolved. Herein, for the inhibition of proton-induced side reactions, a lean-water polymer electrolyte is developed through the chelation of carboxymethyl chitosan (CCS) with Zn2+ ions. In accordance with Fajans' rules, CCS with highly polar carboxylate and strong electron-withdrawing amino groups exhibits enhanced ionic polarizability, which forms distinctive solvation structures with reduced deprotonation energy. Such solvation structures demonstrate competitive advantages in interfacial deprotonation dynamics and minimize proton release to suppress electrochemical corrosion via sacrificial protection. Furthermore, the crosslinked framework induced by molecular crowding restricts free water mobility, thereby alleviating zinc chemical corrosion and cathodic structure deterioration. By employing advanced MRI technology, the movement trajectories of water molecules and the dynamic deprotonation evolution process are directly visualized. Therefore, the cyclically rested Zn symmetric cell impressively operates 4000 h at low current density of 0.1 mA cm-2. Additionally, the Zn||NH4VO full cell exhibits 81% capacity retention after cycling over 1000 cycles at 1 A g-1, while the aqueous electrolyte only maintains 31%.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"19 1","pages":"e2509622"},"PeriodicalIF":29.4,"publicationDate":"2025-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144370112","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 sulfur-doping strategy that enables the OER pathway on IrO₂ nanoparticles (IrO₂/S) to switch from conventional adsorption evolution mechanism (AEM) to lattice oxygen mechanism (LOM) while maintaining Ir─O bond stability, thus achieving a significant enhancement in both intrinsic activity and durability. Advanced spectroscopies and theoretical calculations reveal that the Ir─S coordination motif within the lattice increases the electron density of the Ir center and enhances Ir─O covalency, thus triggering the LOM pathway. Importantly, the lattice distortion and unsaturated Ir─O coordination within the IrO₂/S generate the oxygen nonbonding state that acts as an electron sacrificial agent to preserve Ir─O bonds upon the LOM-dominated OER process. As a result, PEMWE integrated with such IrO₂/S electrocatalyst delivers a low cell voltage (1.769 V at 2.0 A cm^-2) and long-term stability (16.6 µV h⁻¹ over 1000 h@1.0 A cm⁻²) while dramatically reducing Ir usage from 1.0 to 0.3 mg cm^-2.

Of particular interest are heterostructures based on 2D van der Waals (vdW) magnets, which benefit from superior interfacial controllability, mechanical flexibility for smart storage platforms, and open‐source for large‐scale production. However, how heat affects the ultrafast magnetization dynamics in such systems, and/or how the spin dynamics can provide alternative pathways for effective heat dissipation have so far been elusive. Here it is shown that the missing link between magnetization dynamics and heat transport is mediated by the thermal conductivity mismatch between the underneath substrate and the vdW magnet. By modeling the laser‐induced ultrafast spin dynamics of three popular vdW materials (CrI<jats:sub>3</jats:sub>, CrGeTe<jats:sub>3</jats:sub>, Fe<jats:sub>3</jats:sub>GeTe<jats:sub>2</jats:sub>) of different electronic characteristics across sixteen substrates of distinct chemical composition, it is found that both the demagnetization and remagnetization timescales are very sensitive to the phonon temperature dynamics through the supporting materials, which defines the heating dissipation efficiency at the interface. The process can be further tuned with the thickness of the vdW magnets, where thin (thick) systems result in faster (slower) magnetization dynamics. It is unveiled that the non‐thermal nature of spin dynamics in vdW heterostructures creates interfacial spin accumulation that generates spin‐polarized currents with dominant frequencies ranging from 0.18 to 1.0 GHz accordingly to the layer thickness and substrate. The findings demonstrate that substrate engineering liaised with the choice of magnetic compounds open venues for efficient spin‐heat control, which ultimately determines the optically excited magnetic characteristics of the vdW layers.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"46 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2025-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144341067","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}
