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 This final lecture will explore the notion of immunoception, showing how the brain is able to detect and interpret signals of immune origin as a true sense in its own right. Drawing on recent work, it will illustrate how these perceptions can …

Exceptionally, this conference will be held on a Tuesday. Abstract Here, despite the almost total loss of architectural structures, the remains of this temple have revealed the presence of abundant royal and divine statuary of various types and materials, …

Abstract The theater, as a space where people speak to a collective body, is by its very nature a place where power is exercised. This tripartite power emanates from the text, the artists and the audience. It is within this three-tiered billiard …

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 Freshwater fish faunas have evolved in isolation on different continents over millions of years, creating distinct biogeographical regions with specific compositions. Freshwater fishes are the only vertebrate group for which regions are composed …

Abstract As misfortune never comes alone, the causes of biodiversity loss never act in isolation. Biological invasions are part of a general context of global change, including habitat loss, climate change and pollution. And each threatened species is …

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 The line defects of three dimensional uniaxial nematics have a simple abelian algebra governing their interactions and so simply pass through one another. I will discuss, instead, biaxial nematics for which the fundamental group is non-abelian. …
