One system that has been proposed for these applications is the versatile Eu(II)/Eu(III) redox couple, where either species has diverse and tunable optical and electrochemical properties. Here, the details of the processes involved in electron transfer from and to europium centers are considered and probed using seven differing organic dyes in dimethyl sulfoxide (DSMO)─the only solvent where all species are soluble and can be oxidized and reduced. Most dyes were reduced by Eu(II), but one dye, triazatriangulenium (TATA), enabled an experimental determination of quenching by Eu(III) and Eu(II) via photoelectron transfer quenching. It was found that while Eu(III) does not interact strongly with the organic dyes, Eu(II) is a potent reducing agent for organic molecules, disregarding whether the substrate is in the ground state or the excited state. We concluded that ground state reduction of any substrate by Eu(II) must be considered in all cases, where photoredox chemistry involving the Eu(II)/Eu(III) redox couple is explored. Finally, we advocate that the redox potentials of all involved species be determined if a mechanism is proposed.","PeriodicalId":62,"journal":{"name":"The Journal of Physical Chemistry Letters","volume":"70 1","pages":"7816-7823"},"PeriodicalIF":6.475,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144701201","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}

While useful for real-time imaging, few such probes are available. Existing tools also exploit similar mechanisms for signal turn-on, precluding multiplexed applications. To address these gaps, we developed a palette of cyclopropenone (CpO) scaffolds that are activated by bioorthogonal phosphines to produce coumarins. The top CpO-phosphine pairs show strong fluorescent enhancements (up to 760-fold), high quantum yields, and stability in aqueous environments. The CpO fluorogens also exhibit unique reaction profiles, setting the stage for multicomponent labeling studies.</p>","PeriodicalId":57,"journal":{"name":"Journal of Organic Chemistry","volume":" ","pages":"10545-10549"},"PeriodicalIF":3.3,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144606790","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}

{"title":"Comparing sustainable fuel adoption in the energy transition for maritime and aviation transport","authors":"Tansu Galimova ,&nbsp;Sotiria Lagouvardou ,&nbsp;Hamed Kian ,&nbsp;Christian Breyer","doi":"10.1016/j.rser.2025.116124","DOIUrl":"10.1016/j.rser.2025.116124","url":null,"abstract":"<div><div>Maritime and aviation transport are widely recognised as sectors where reducing greenhouse gas emissions is particularly challenging due to their reliance on energy-dense fuels and the challenges associated with direct electrification. These sectors face increasing pressure to defossilise and reduce emissions in line with global climate goals, while simultaneously facing unique technological, operational, and economic uncertainties. This study addresses a key research gap by comparing the maritime and aviation sectors for common factors and sector-specific differences in their transition to green e-fuels produced from renewable electricity and sustainable CO₂. A techno-economic assessment is conducted to evaluate alternative fuel and propulsion options using the levelised cost of mobility framework. The analysis also incorporates the pricing of non-CO₂ greenhouse gases and air pollutant emissions. Results show that e-ammonia or e-LNG combustion is the most cost-effective option for maritime transport, when emission costs are excluded, whereas hydrogen fuel cells become more economical when these costs are internalised. In aviation, e-kerosene use in conventional aircraft presents the lowest costs, regardless of the year or emission pricing. The findings highlight the importance of considering unique characteristics of each sector and tailored defossilisation and decarbonisation strategies that consider sector-specific constraints. To sustainably meet the growing demand for transport fuels, rapid investments in renewable electricity generation, electrolysers, and e-fuel synthesis are essential. Development of strong regulatory frameworks and financial instruments will be critical to support early deployment of e-fuels and minimise the risks.</div></div>","PeriodicalId":418,"journal":{"name":"Renewable and Sustainable Energy Reviews","volume":"224 ","pages":"Article 116124"},"PeriodicalIF":16.3,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144703276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
