Abstract If we consider the role of the book as a communication tool, an analysis of its different materials and forms can reveal aspects of its use and function. For example, its dimensions and form can influence its mobility, its materials can affect …

Abstract Over the last three decades, the highly tunable properties of NHCs and other stable singlet carbenes have led to a variety of applications. We will discuss a novel facet of carbenes, i.e., their reductive properties, which allows carbenes to …

Abstract We demonstrate water activation by a photocatalytic phosphine-mediated radical process, generating a PR3-H2O radical cation intermediate, where both hydrogen atoms are used in the following chemical transformation through sequential cleavage of …

Abstract Originally discovered via vapor-phase pyrolysis of p-xylene , 1 [2.2]paracyclophanes (pCps) have garnered significant attention due to their unique three-dimensional architecture2 and inherent planar chirality. 3 Despite their promising …

Abstract As part of the organic chemistry, radical chemistry is an important research area as the one electron reactivity is complementary to the ones of the two electrons and polar manifolds. In this regard, electrochemistry, which enjoy a renewal, …

Abstract Historically, group-1 alkali metal chemistry is dominated by +1 oxidation state. As the least electronegative elements in the Periodic Table, zero-valent alkali metals are prone to give out their only valence shell electron, i.e., acting as …

Abstract Our group aims to study the total synthesis of complex natural products. We particularly deploy oxidative coupling strategies via single electron transfer (SET) processes among others tactics. We also study electrochemistry to access three …

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 …

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 …

Abstract The question of how heritable mutations arise is one of long-standing interest in biology. In the case of bacteria, there was a debate about whether mutations arise as a consequence of adaptation to selective pressure from the environment, or …

Abstract Computational quantum physics has recently seen a dramatic increase in its capabilities, precision, and predictive power. The advances have been driven by method and code development, benchmark, and collaboration. Together with exciting recent …

Abstract After a brief introduction to the CGDD, the research sub-department and their involvement in geoengineering, this talk will present current French positions on the two main families of techniques, carbon removal (EDC) and solar radiation …

Abstract Marine geoengineering (the specific subject of this talk) is one of the scientific techniques that could ultimately help combat global warming. As such, it is the subject of this symposium. However, it also presents a serious and irreversible …

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 …

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 …

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 …

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 …
