Taking into account all the experience and knowledge of Prof. Jean Louis Souquet, we suggest, as an working plan for his stay in the Laboratory of Glass Materials (LaMaV) of the DEMa/UFSCar, the investigation of several problems concerning the ionic and electronic conductivity of glasses, currently of interest in the group. Among the subjects to be approached, we emphasize: - Ionic conductivity of glass-ceramics solid electrolytes with Nasicon structure. - Ionic transport and viscosity properties in alkaline silicates. - Electronic conductivity in glasses and glass-ceramics from the V2O5-TeO2. (All these subjects are well detailed in the complete project). - Other subjects related to ionic and electronic conductivity in glasses that may come out during the stay of Prof. Souquet. (AU)
