abstract = {We report here a quasi-elastic neutron scattering (QENS)
investigation of the effect of pressure on the diffusivity
properties of water in a dilute aqueous solution of
hydrophobic molecules (tert-butyl alcohol, TBA). The
experiment was performed at fixed TBA concentration (0.02
molar fraction) by varying pressure from 1 to 2000 bar at
two different temperatures (268 and 278 K). The
quasi-elastic line-shapes have been analysed in terms of a
model based on the memory function formalism. Our data
indicate that, on increasing pressure up to 2000 bar, the
diffusion coefficient of water in the TBA/water mixture
exhibits a relative increase larger than that of pure water
under the same thermodynamic conditions. The extent of this
effect increases with decreasing temperature. The observed
behaviour is described in terms of pressure-induced
distortions of the H-bonded random network of liquid water.},
