dc.description.abstractA series of quasi-elastic neutron scattering measurements were performed using IN6 at the Institute Laue Langevin for a mesoporous organosilica material with phenyl functions, called phenyltriethoxysilane (PTES). The aim of the experiment was to study the diffusion dynamics of nano-scale water clusters inside the hydrophobic pores as a function of temperature and hydration. By fitting the Debye–Waller factor, the data show clearly the different behavior between water, both inside and outside the hydrophobic pores, which resembles bulk water. The mean thermal displacement u2 of the external water increases with T almost linearly up to 353 K, while the internal water quickly reaches the maximum at T323 K, indicating the confinement by an averaged pore diameter of the porous organosilica. © 2010, Elsevier Ltd.en_AU
