These experiments are typically interpreted in terms of the Jaynes-Cummings or Tavis-Cummings models under the assumption that the molecular ensemble is only excited by a single photon. In such a model, two polariton states compete with an overwhelming number of dark states, inhibiting polaritonic reactions entropically. We analyze the higher excitation manifolds of the Tavis-Cummings model along with a three-level system that resembles photochemical reactions. We demonstrate that allowing for more than a single excitation makes the reaction of the involved polaritons entropically more favorable.","PeriodicalId":62,"journal":{"name":"The Journal of Physical Chemistry Letters","volume":"114 1","pages":"7807-7815"},"PeriodicalIF":6.475,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144701174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These multivalent interactions stabilize phase-separated droplets, which are critical for chromatin compaction and transcriptional regulation. While inorganic salts such as KCl modulate LLPS in vitro, they do not fully replicate cellular conditions where organic anions dominate. Here, we investigate potassium trifluoroacetate (CF₃COOK) as a substitute for potassium acetate in probing HP1α phase separation using solid-state NMR spectroscopy. CF₃COOK offers unique insights due to its distinct ¹⁹F signals.

This review presents recent advances in numerical simulation tools, ranging from low-fidelity engineering models to high-fidelity computational fluid dynamics (CFD) codes for FOWT aerodynamics. We review various open-source and commercial software developments and summarize validation projects focused on improving the FOWT simulations. Given the dynamic nature of floating turbines, the impact of wake aerodynamics has also been critically assessed. Additionally, data-driven modeling has emerged as a promising approach for improving FOWT design, leveraging data from numerical models and experiments. We discuss the strengths and limitations of various computational methods, highlighting the potential of integrating data-driven techniques with next-generation AI methods.

{"title":"Benzoic Acid-Mediated Oxygen Activation for Efficient Toluene Removal on the Co-Vo-Cu Catalyst via In Situ Ligand Modulation.","authors":"Zhenmin Xu,Ting Zhang,Junyu Lang,Mengli Xu,Ya Xie,Chunyan Wu,Huangrong Wang,Han Yu,Zhenfeng Bian","doi":"10.1021/acs.est.5c08106","DOIUrl":"https://doi.org/10.1021/acs.est.5c08106","url":null,"abstract":"Carboxylates are commonly formed as intermediates during the oxidation of volatile organic compounds (VOCs) and are often regarded as significant barriers to the complete mineralization of organic pollutants. In this study, we present a novel cobalt-doped copper-based catalyst that employs an in situ benzoic acid-mediated oxygen activation strategy for the photocatalytic degradation of toluene under visible-light irradiation. Unlike traditional systems in which carbonyl intermediates contribute to catalyst deactivation, we demonstrate that benzoic acid, generated during toluene oxidation, acts as a potent ligand to modulate the electronic structure of cobalt sites. This interaction significantly enhances oxygen activation and promotes the generation of reactive oxygen species (ROS), facilitating the complete oxidation of toluene to CO2 with nearly 100% efficiency. In situ characterization and density functional theory (DFT) calculations reveal that the migration of benzoic acid from copper to cobalt sites under visible light is critical for the oxidation process. This migration induces a pronounced electron-donating effect, enabling activation of the Co center, which drives efficient ROS production and autocatalytic mineralization of benzoic acid. The resulting Co-Vo-Cu catalyst demonstrates exceptional catalytic activity and stability, outperforming previous systems in VOCs degradation. This work offers new insights into the role of organic intermediates in oxygen activation and presents a promising strategy for the development of next-generation photocatalysts for VOCs elimination.","PeriodicalId":36,"journal":{"name":"环境科学与技术","volume":"37 1","pages":""},"PeriodicalIF":9.028,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144701190","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
