Collège de FranceAnnée 2023-2024Grand événementGrand événement - Vers une société résiliente au changement climatique / Building a Climate Resilient Society : Sustainable Chemistry and Hydrogen as Pillars of the Energy TransitionDr Deborah JonesCentre national de la recherche scientifique (CNRS)RésuméClean hydrogen, as an energy vector and a sustainable chemical feedstock, is a pillar of the energy transition and key contributor to meeting the targets for net zero greenhouse gas emissions by 2050 and thereby to building a climate-resilient society. Reaching these objectives requires us to ensure viable materials solutions for implementation of hydrogen technologies in the short term, while also addressing the long-term requirement of safeguarding the sustainability of the hydrogen sector through a radical reconsideration of the criticality of the chemistries, materials and components.Deborah Jones (B.Sc., Ph.D. University of London, King's College) is Director of Research at CNRS at the Institute for Molecular and Materials Chemistry in Montpellier (ICGM), of which she was associate director 2015-2020. Her interests encompass the development and operando characterisation of hydrogen energy materials in particular for proton and anion exchange membrane fuel cells and electrolysers. Author/co-author of > 250 publications, and inventor on 17 patents related to fuel cell and electrolyser materials, she is a former vice-president of the International Society of Electrochemistry, Fellow of the Electrochemical Society (2015), recipient of the Sir William Grove award of the International Association for Hydrogen Energy (2016) and of the Schönbein Gold Medal (2023). Experienced EU collaborative project coordinator, other of her responsibilities in European research include those of chair of the ERC PE4 Consolidator Grants panel and former vice-chair of the Scientific Committee of the Fuel Cells and Hydrogen Joint Undertaking. Deborah is associate director of the Occitanie Region "Key Challenge" on Clean Hydrogen gathering all academic research laboratories working on hydrogen topics in the Occitanie region, and director of the Laboratoire Commun between CNRS-ICGM and Michelin, on Sustainability of Materials and Processes for the Hydrogen Sector since its inception in July 2022.

Collège de FranceAnnée 2023-2024Conférencier invité - Piet Lammers :La transition de Berezinsky-Kosterlitz-Thouless au point critique (1)Piet LammersMathématicien, chaire de professeur junior au CNRS et au laboratoire de probabilités, statistique et modélisationPiet Lammers, mathématicien, occupe actuellement le poste de chaire de professeur junior au CNRS, où il est rattaché au Laboratoire de probabilités, statistique et modélisation (Sorbonne Université). Originaire de Groningue, il est diplômé de l'université d'Utrecht et a poursuivi sa thèse sous la direction de James Norris à l'université de Cambridge. Pendant son séjour à Cambridge, il a séjourné dans une résidence collaborative aux côtés de trois autres mathématiciens néerlandophones. En 2018, il a été honoré du prix d'essai Smith-Knight et Rayleigh-Knight en reconnaissance d'une partie de ses travaux de thèse. Par la suite, il a effectué des recherches postdoctorales au sein du groupe dirigé par Hugo Duminil-Copin à l'IHES.Les travaux de Piet Lammers se concentrent principalement sur les problèmes issus de la mécanique statistique. En appliquant des techniques issues de la combinatoire et de la théorie des probabilités, ses recherches ont apporté une contribution significative à la compréhension de la transition Berezinskii-Kosterlitz-Thouless ainsi qu'à la brisure spontanée de symétrie en deux dimensions. Ses collaborations scientifiques s'étendent à différents groupes de recherche en Europe, notamment en France, en Suisse et en Autriche.Piet Lammers est lauréat du Prix Claude-Antoine Peccot pour l'année 2023-2024.

Collège de FranceAnnée 2023-2024Conférencier invité - Jessica Fintzen : Representations of p-adic GroupsJessica FintzenProfesseure à l'institut de mathématiques de l'Université de BonnRésuméThe first lecture is aimed at a general math audience and will be an introduction to the representation theory of p-adic groups and its relation to other areas. It will include an overview of the construction of representations of p-adic groups as well as the structure of the category of all (smooth) representations of p-adic groups.IntervenantsJessica FintzenProfesseure à l'institut de mathématiques de l'Université de Bonn

Collège de FranceAnnée 2023-2024Grand événementVers une société résiliente au changement climatique / Building a Climate Resilient Society : Electroreduction of CO2 to Hydrocarbons and Alcohols: ChallengesMarc FontecaveProfesseur du Collège de FranceRésuméConversion of carbon dioxide into hydrocarbons (methane, ethylene) and alcohols (ethanol, propanol) using renewable electricity as an energy source is an attractive strategy for storing renewable energies (solar and wind energy) into the form of chemical energy (a fuel) and using carbon dioxide as a raw material for the synthesis of chemical products. However, carbon dioxide activation is a complex process which implies multiple electron and proton transfers, resulting in the need for stable, efficient and selective catalysts in order to make this strategy a practical industrial option. Here we discuss our ongoing research using original Cu-based catalytic materials and addressing several issues associated with on carbon dioxide electrolysis, such as activity, selectivity, carbonate formation and carbon loss. This led us to investigate the effect of molecular modification of catalyst surfaces, optimization of electrolysis under acidic conditions as well as carbon monoxide electroreduction into ethylene and alcohols.Marc FontecaveAfter a PhD at École normale supérieure in Paris (1984), a post-doctoral internship at Karolinska Institute, Stockholm (1985-1986), 20 years as Professor of Chemistry at University Joseph Fourier, Grenoble (1988-2008), Marc Fontecave is, since 2009, Professeur at Collège de France, Paris. He is a member of the French Academy of Sciences and of the Royal Swedish Academy of Sciences. His research focusses on catalysis (homogeneous, heterogeneous, bioinspired) and biocatalysis (metalloenzymes and artificial enzymes) for water and carbon dioxide electrolysis.

Collège de FranceAnnée 2023-2024Grand événementVers une société résiliente au changement climatique / Building a Climate Resilient Society : Climate, Energy, and History in Long PerspectiveKyle HarperUniversité de l'Oklahoma et Fractal Faculty, Santa Fe Institute. Professeur invité du Collège de FranceRésumé​This presentation will provide a long perspective on the importance of energy transitions in human history and underscore the role of ingenuity, innovation, and adaptation in the past – and future – success of our species.Kyle Harper is the G.T. and Libby Blankenship Chair in the History of Liberty, Professor of Classics and Letters, at his alma mater, the University of Oklahoma. He is also a Fractal Faculty member at the Santa Fe Institute, and in 2023-24 the holder of an annual Chair at the Collège de France (chaire "Avenir Commun Durable"). Harper has been a Guggenheim Fellow and an Andrew Carnegie Fellow in addition to a Junior Fellow at Dumbarton Oaks. Harper is a historian whose work tries to integrate the natural sciences into the study of the human past. His main research interests include the history of infectious disease and climate change and their impact on human societies. More broadly, he writes on the history of humans as agents of ecological change and asks how we can approach questions such as biodiversity, health, and environmental sustainability from a historical perspective. He is the author of four books. His first book, Slavery in the Late Roman World; From Shame to Sin: The Christian Transformation of Sexual Morality; The Fate of Rome: Climate, Disease, and the End of an Empire; and Plagues upon the Earth: Disease and the Course of Human History.
