    Cette présentation sera l’occasion dans un premier temps de discuter des propriétés chimiques des éléments actinides (5f) les plus marquantes en solution aqueuse. Parmi celles-ci, le comportement rédox sera plus particulièrement abordé.
    Dans une seconde étape, les grands axes de Recherche & Développement seront présentés, en se focalisant sur les éléments transuraniens (Z>92).
    Enfin, une...

    Paramagnetic NMR measures the NMR chemical shift of paramagnetic complexes compared to their diamagnetic counterpart. This shift may be split into
    dipolar terms, arising from the magnetic dipolar interaction between the metal center and the NMR active nucleus, and the contact term, due to the spin delocalization leaking from the paramagnetic center towards the ligand [1]. The separation of...

    Une meilleure compréhension des propriétés structurales et physico-chimiques des nanoparticules colloïdales d'oxyde de plutonium (PuO2) suscite un intérêt pour élucider les schémas de migration environnementale de cet élément radioactif à vie longue, mais aussi pour le développement potentiel de combustibles nucléaires avancés.[1,2] Les suspensions colloïdales issues de l'hydrolyse de Pu(IV)...

    The field of molecular magnetism has witnessed remarkable progress in the last decades, fuelled by the discovery of single-molecule magnets (SMMs).[1,2,3] Research into SMMs in the decades that followed saw the introduction of lanthanide ions into these complexes thanks to their high spin and strong intrinsic magnetic anisotropy.[4,5] Some lanthanide ions also have very specific optical...

    Palladium-mediated transformations are dominated by Pd ()0 and Pd(II) species, whereas the reactivity of higher oxidation states such as Pd(III) and Pd(IV) are far less explored because of the low accessibility and stability of these species.[1]
    Herein, we present the synthesis, characterization, and reactivity of a novel Pd(IV) - alkyl complex.
    The stabilization of the Pd(IV) species...
