Sarah HOCINE (LMCT) will defend her Ph.D. dissertation entitled "Adsorption of alkali cations and electrokinetic phenomena on charged silica surfaces" on Thursday, September 28, 2017 at 1.30 pm (ICSM Auditorium).
Abstract: In confined structures, such as mesoporous silica, the mobility of the cations and the surface/cations interactions are key phenomena. They drive adsorption properties, which control numerous applica- tions, especially for extraction and separation. This modelling work describes equilibrium and transport interface properties that control ion exchange and ionic adsorption. This work allows a better characterization of charged glass-solution interfaces for separation science. It shows how molecular simulations can not only predict the parameters of macroscopic models (adsorption constant, transport coefficients), but also modify the latters in order to make them in agreement with molecular descriptions. Such a strategy can be extended to more complex systems, such as models of grafted surfaces.
