We also study electrochemistry to access three … 14 May 2025 11:20 - 12:10 Event Laurence Grimaud Electro-Induced Isocyanide-Based Multicomponent Reactions Symposium Abstract Since the pioneering report of the oxidative three-component Passerini reaction using a stoichiometric oxidant, [1] oxidative Isocyanide-based multicomponent reactions (IMCRs) have opened new avenues for accessing diverse chemical space from … 14 May 2025 10:00 - 10:50 Event Burkhard König Better Organic Synthesis with Light Symposium Abstract Photoinduced electron transfer is the key step in photoredox catalysis. We will briefly review the essential parameters affecting photoinduced electron transfer and how we can control them for the benefit of synthesis. Next, we discuss recent … 14 May 2025 09:10 - 10:00 Event Dionysios Anninos Cosmological 'Ising' Models Seminar Abstract We discuss the role simplified controllable models may play in sharpening and solving questions in quantum cosmology. Some focus will be placed on lower dimensional models.

As such, it is the subject of this symposium. However, it also presents a serious and irreversible … 15 May 2025 14:45 - 15:30 Event Fabrice Del Corso CO2, from use to geological storage Symposium Abstract CO 2 is a molecule that has already been used on a large scale for decades for a variety of applications: chemistry, agri-food, plant growth, extinguishing agent, water treatment... The geological storage of CO 2 has also been implemented for … 15 May 2025 14:00 - 14:45 Event Caroline Thaler Negative emissions: the startup ecosystem in France Symposium Abstract Achieving carbon neutrality (Net Zero) by 2050 requires, in addition to massive emissions reductions, the development of tools to actively remove CO 2 from the atmosphere. So-called "negative emissions" technologies have become an indispensable … 15 May 2025 12:15 - 13:00 Event Nicolas Viovy Carbon capture and storage by terrestrial ecosystems and nature-based solutions Symposium Abstract Most scenarios developed to limit global warming involve negative emissions, i.e. the sequestration of carbon dioxide from the atmosphere. In this context, ecosystems, which currently absorb almost a quarter of our emissions, represent one of the … 15 May 2025 11:30 - 12:15 Event Éric Lambin Changes in solar radiation: risks, uncertainties and governance Symposium Abstract A commonly discussed form of geoengineering is the modification of solar radiation. A number of technologies could be used to reduce solar radiation incident on the Earth in order, in theory, to counteract global warming. In 2024, the European … 15 May 2025 10:20 - 11:10 Event Francis Albarède Geoengineering assessment at the Academy of Sciences Symposium Abstract This presentation explores geoengineering – a set of ideas aimed at cooling the planet if cutting greenhouse gas emissions isn’t enough to stop climate change.
