Peroxymonosulfate activation by iron-rich biochar derived from sewage sludge digestate for sulfamethoxazole degradation: A rigorous examination of performance and mechanistic insights
No full textInternational audienceThe ubiquitous presence of sulfamethoxazole (SMX) within aquatic ecosystems coupled with the increasing production of solid waste digestate has emerged as a critical environmental challenge. This necessitates the development of efficient decontamination strategies and sustainable waste management approaches. This study introduces iron-doped biochar (FBC-600), synthesized via pyrolysis of sewage sludge digestate (SSD), as an effective catalyst for peroxymonosulfate (PMS) activation to degrade SMX in aqueous media, thereby transforming this waste byproduct into a valuable material for environmental remediation. The FBC-600/PMS system exhibited efficient SMX removal nearly complete within 90 min under optimized conditions. Notably, the system demonstrated robustness against pH variations and the presence of inorganic ions. Mechanistic investigations implicated singlet oxygen (1O2) and electron transfer as predominant reactive oxygen species (ROS). The catalytic performance was attributed to the synergistic interplay of Cdouble bondO, embedded iron, structural defects active sites on the FBC-600 surface. Moreover, the catalyst exhibited exceptional reusability and minimal iron leaching. The transformed products of SMX were examined through density functional theory (DFT) calculations and Liquid Chromatography-Mass Spectrometry (LC-MS). Concomitantly, the estimated toxicity of the identified intermediates was determined to be lower than that of SMX. This study highlights the potential of FBC-600 as a sustainable catalyst for SMX degradation by valorizing industrial bio-digestate according to zero-waste principles, which aim to minimize waste through strategies such as, reusing, reducing, recycling, refusing and composting
Alice Ceresa, tradotta e traduttrice
No full textInternational audienceThis volume investigates for the first time the multilingual and transnational dimension of the work of Alice Ceresa (1923–2001), one of the most original voices in 20th-century Italian-language literature. The essays collected here show how the practice of translation accompanied the writer's entire intellectual journey, intertwining with her criticism of gender inequality and the multilingualism of her Swiss origins. What emerges is the profile of a truly European author, capable of crossing linguistic, cultural and identity boundaries with consistency and radicalism.Questo volume indaga per la prima volta la dimensione plurilingue e transnazionale dell’opera di Alice Ceresa (1923-2001), una delle voci più originali della letteratura in lingua italiana del Novecento. I saggi qui raccolti mostrano come la pratica della traduzione accompagni l’intero percorso intellettuale della scrittrice, intrecciandosi alla critica delle disuguaglianze di genere e al plurilinguismo delle sue origini svizzere. Ne emerge il profilo di un’autrice autenticamente europea, capace di attraversare con coerenza e radicalità confini linguistici, culturali e identitari

O que a IA faz ao jornalismo, o que o jornalismo faz à IA. O caso da imprensa francesa
No full textInternational audienceThis proposal uncovers the foundations of (de)legitimization of artificial intelligence in the mission to inform, in a context where informational fatigue and news avoidance further accentuate the economic crisis of media companies. The study is based on two research fields: the media discourses of the French National Press dealing with the integration of AI in journalism and the ethics codes set up by some major French media to frame the uses of AI in their newsrooms. The analysis reveals conflicting perceptions about what constitutes AI’s benefits and threats to news journalism. While AI is supposed to help news outlets produce quality journalism, the reported practices are dependent on the profitability of the media business and the appetites of US AI development companies. The charters issued by the professional milieu of journalism then set the main red lines not to be crossed in order to counter these drifts.Este artículo examina los fundamentos de la (des)legitimación de la inteligencia artificial (IA) en el periodismo, en un contexto marcado por la fatiga informativa y el fenómeno de news avoidance, que agravan la crisis económica de las empresas mediáticas. El estudio analiza tanto los discursos mediáticos de la prensa nacional francesa sobre la integración de la IA como los códigos deontológicos adoptados por algunos grandes medios para regular su uso en las salas de redacción. Los resultados revelan percepciones contradictorias sobre las ventajas y amenazas de la IA para el periodismo. Aunque estas tecnologías están diseñadas para mejorar la producción de contenido informativo, las prácticas observadas tienden a priorizar la rentabilidad de las empresas mediáticas y los intereses comerciales de las corporaciones tecnológicas. En respuesta, los códigos deontológicos establecen líneas rojas para limitar estas posibles desviaciones y preservar los principios éticos del periodismo.Este artigo examina os fundamentos da (des)legitimação da inteligência artificial (IA) no jornalismo, em um contexto marcado pela fadiga informativa e pelo fenômeno da evasão de notícias (news avoidance), que agravam a crise econômica das empresas de mídia.

Comportement des CAP-O dans les sols
No full textInternational audienceSur les sites pollués par des HAP (Hydrocarbures Aromatiques Polycycliques), d’autres familles de composés aromatiques polycycliques pourraient contribuer à l’impact et donc au risque pour l’Homme et l’Environnement, comme les CAP-O (Composés Aromatiques Polycycliques Oxygénés). Cependant, ils ne sont pas pris en compte actuellement car leur comportement dans les sols n’est pas suffisamment documenté. Dans le cadre de ces travaux, l’évaluation de la sorption dans le sol, au laboratoire, de HAP et de CAP-O a montré que, d’une manière générale, les mécanismes sous-jacents et les sites de sorption sont différents pour les deux familles de molécules. Ainsi, le taux de matière organique du sol n’est pas le paramètre principal contrôlant la sorption des CAP-O, contrairement aux HAP. La sorption des CAP-O serait contrôlée par des mécanismes ayant lieu à la surface des particules de sol, de type échange d’ions.. Par ailleurs, il a été montré que, d’une part, les CAP-O présentent une affinité plus faible pour la matrice solide que les HAP, et que, d’autre part, les CAP-O sont relargués préférentiellement dans l’eau par rapport aux HAP,, ce qui implique une mobilité plus importante des CAP-O dans les sols, comparativement aux HAP
