1 In this study, we characterized the structure and the dynamics at a picosecond scale of water molecules in aqueous solutions with cations having various kosmotropic properties (XCl2 where X = Ba2+, Ca2+, and Mg2+) confined in highly ordered mesoporous silica (MCM-41 and grafted MCM-41) by Fourier transform infrared spectroscopy and quasi-elastic neutron scattering.

2 These results suggest that whatever the ions kosmotropic properties, for pore sizes phip < 2.6 nm and [XCl2] <= 1 M, the water dynamics is mainly slowed down by the size of the confinement. Water X-C motif chemokine ligand 2 Homo sapiens
