Accreditation to supervise research

The author gives an overview of his research activities since 1994. He first studied the molecular mechanisms involved in the retention or adsorption of transition elements (Co, Zn) on clay minerals. Then, he aimed at developing the knowledge about the atomic structure of mineral-solution interfaces, and notably the effects of reconstruction and structural reorganizations (works on the SiO2-solution interface, on muscovite surfaces, on mica-solution interfaces). His investigations then concerned montmorillonite reactivity, the retention of lanthanides, and other solids like calcium silicates produced during concrete hydrating
