Markus BAUM (LNER) will defend his Ph.D. dissertation entitled "The role of water properties and specific ion effects on the evolution of silica nanoconfinement" on Friday, November 9, 2018 at 10.00 am (ICSM Auditorium).
In this study, we investigated the water properties in the presence of ions in silica nanoconfinement. The main objective is to relate these water properties to the evolution of silica mesoporous materials in aqueous solutions. To reach this goal, we used an original approach, consisting in the use of electrolyte solutions having more or less kosmotropic properties XCl2 (X = Ba, Ca, Mg) confined in model systems such as two parallel and plane silica surfaces spaced of 3 and 5 nm (nanochannels) and highly ordered mesoporous silica materials represented by SBA-15 (6 nm pore size and microporous pore wall) and MCM-41 (3 nm pore size and dense pore wall).
