Adsorption and local dynamics of confines water molecules in NaY faujasite: Neutron Compton scattering view

Already in the low temperature region of the water adsorption behaviour in faujasite NaX at different hydration levels, an important question arise: is this behaviour extrapolated to other zeolites of the same family, such as NaY. This proposal aims to shed more light on this question by conducting experiments of Neutron Compton Scattering (NCS) in H2O confined in a NaY faujasite network at temperatures below 200K. Also this proposal will give some clues about the possible role and type of nuclear quantum tunnelling (NQT) in the dynamics of confined water molecules in zeolites.
