[en] The aim of these workshops is to define precisely each chosen topic; seven topics have been chosen: 1)chemical and physical properties of massive actinides in metallic, oxide or nitride state; 2) interfacial chemistry under reactive conditions; 3)ion separation using bio-inspired supra-molecular self-assembled colloids; 4)furtive chemistry: sono-chemical processes in complex fluids; 5)self-repairing of hybrid nano-materials with hierarchical structure; 6)interface of materials under rapid evolution; 7)isotopic imaging of amorphous solids.
