Abstract
The microscopic dynamics of hydration water exhibits some universal features that do not
depend on the nature of the hydrated surface. We show that the hydration level dependence of
the dynamic transition in the mean squared atomic displacements measured by means of elastic
neutron scattering is qualitatively similar for hydration water in inorganic and organic hosts.
The difference is that the former are ‘rigid’, whereas the dynamics of the latter can be enhanced
by the motions of the hydration water. The overall hydration level appears to be the main
parameter governing the magnitude of the mean squared atomic displacements in the hydration
water, irrespective of the details of the hydrated host.
