Abstract This study presents the first comprehensive analysis of a significant Qurʼanic manuscript discovered in the Geniza of the Imām Riḍā shrine in Mashhad, comprising 244 fire-damaged folios. The manuscript's colophon identifies its scribe as Abū ʿAlī …

Abstract The study of Medieval bookbinding in the Muslim world has come up against major methodological problems, but faces also (and perhaps because of these problems) a certain scepticism on the part of specialists in manuscript studies. The Escorial …

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 Demographic transitions are often attributed to reduced fertility, triggered by significant developments in several areas. In this respect, health gains in Africa should be more widely recognized as a driver of its population growth. The fact …

Panagiota Sarischouli is invited by Prof. Jean-Luc Fournet, Chair of Written Culture in Late Antiquity and Byzantine Papyrology . Abstract Although the phenomenon of voces magicae is most often associated with Roman and Late Antique Egypt, the use of …

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. …

Abstract Over the past three years, negotiations under the parallel processes of the post-Cotonou agreements and the agreements reached between the European Union (EU) and the African Union (AU), initiated following the AU-EU Abidjan Summit in November …

Round table moderated by Myriam Cottias, CNRS, CIRESC, with the participation of Catherine Porter, New York Times , Magali Bessone, Université Paris 1 …

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 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 …
