Neutron scattering observation of quasi-free rotations of water confined in carbon nanotubes OPEN
International audience In this paper we study the translational and rotational diffusion of water trapped in up-to-50-μm-long (10, 10) SWCNTs of diameter d = (1.4 ± 0.1) nm by quasi-elastic neutron scattering (QENS), in the temperature interval from 300 to 10 K, with the purpose of observing the for...
