Anomalous dynamics of confined water at low hydration
arXiv:cond-mat/0311286 · doi:10.1088/0953-8984/15/45/002
Abstract
The mobility of water molecules confined in a silica pore is studied by computer simulation in the low hydration regime, where most of the molecules reside close to the hydrophilic substrate. A layer analysis of the single particle dynamics of these molecules shows an anomalous diffusion with a sublinear behaviour at long time. This behaviour is strictly connected to the long time decay of the residence time distribution analogously to water at contact with proteins.
