Herein, we present a comprehensive study on Na+ desolvation and transport kinetics across solid electrolyte interphases (SEIs) with diverse chemical natures. Although inorganic-rich SEIs are generally regarded as favorable for Na+ transport, our results reveal that certain organic-rich SEIs can deliver comparable or even superior kinetic performance. Guided by these insights, we construct a Poly(MMA)-based artificial SEI on commercial HC (Type-1), which reorganizes the Na+-DME solvation shell at the inner Helmholtz plane into a Na+-DME/Poly(MMA) coordination environment. This interfacial reconstruction markedly enhances Na+ desolvation and interphase transport, enabling exceptional rate performance (236 mA h g-1 at 5 C) and long-term cycling stability (99% capacity retention over 1000 cycles) for the commercial Type-1 HC. The effectiveness of the Poly(MMA)-derived interphase is further validated in both coin-type and pouch-type full sodium-ion chemistries, as well as in lithium-ion batteries. This work unveils the pivotal role of interfacial solvation structure, beyond the organic/inorganic ratios of SEI, in governing Na+ kinetics, offering a new design paradigm for next-generation fast-charging SIBs.","PeriodicalId":125,"journal":{"name":"Angewandte Chemie International Edition","volume":"129 1","pages":"e202516068"},"PeriodicalIF":16.6,"publicationDate":"2025-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145331892","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, we need to find alternative routes to produce chemical building blocks, such as aromatics, which are used in products like, for example, fuels. In this study, we investigated a two-stage route to produce benzene from CO2. In two sequential reactions, CO2 is first converted into methane over a Ni/TiO2 catalyst, and methane is further reacted to yield benzene using a Mo/ZSM-5 catalyst via the methane dehydroaromatization (MDA) reaction. Through a combination of thermodynamic calculations and experiments, we found the goldilocks conditions for performing this two-stage process. The unreacted CO2 and H2 from the first reaction extended the benzene production in the second reaction. Using a reaction mixture of CO2, H2, and CH4 resulted in benzene production of at least 72 h, by suppressing carbon growth on the catalyst surface. However, the concentration range in which CO2 and H2 can be added to the feed without losing benzene production is narrow, as we show with H2 fluctuation experiments. We demonstrate that the combination of CO2 methanation and MDA allows us to catalytically convert CO2 into benzene with an overall yield of 5%.","PeriodicalId":125,"journal":{"name":"Angewandte Chemie International Edition","volume":"34 1","pages":"e202517563"},"PeriodicalIF":16.6,"publicationDate":"2025-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145331748","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The introduction of Se influenced the surface and interface properties of the NiFeSe, including enhanced surface roughness, facilitated rapid nucleation and detachment of smaller oxygen bubbles, and reduced bubble-induced diffusion limitations. As a result, the NiFeSe catalyst achieved a low overpotential of 190 mV at 1000 mA cm-2 and demonstrated a high durability beyond 2000 h in 1 M KOH. In the practical AEM-WE device, it reached 8800 mA cm-2 at 2.0 V and worked continuously for over 3000 h at 1000 mA cm-2.

To overcome this limitation, we developed a general molecular engineering strategy to confer BODIPY with spirocyclic functionality: Introducing 2-(hydroxymethyl)phenyl or 2-carboxyphenyl groups at the meso-position as intramolecular nucleophiles, coupled with electron-withdrawing groups at α/β-positions to modulate core electron density and enhance meso-carbon's electrophilicity. We present the first single-crystal X-ray structure of a spirocyclized BODIPY, unambiguously confirming the closed form and its blinking mechanism. By tuning this system, we established a clear pKa-structure-activity relationship, enabling precise prediction and customization of the open-closed equilibrium. The resulting spirocyclization-capable BODIPYs exhibited exceptional brightness up to ∼87,122 M-1 cm-1, and enable self-blinking super-resolution imaging of mitochondria and lysosomes in living cells under low-power laser density (≥32 W cm-2) without requiring imaging-enhancing buffers.
