„Water and polymer chains dynamics in chitosan hydrogels by quasielastic neutron scattering”
The present paper presents the results of QENS measurements on semi-dilute chitosan solutions at different temperatures for uncrosslinked sample and a crosslinked sample. The samples were characterized a priori using Atomic Force Microscopy. From the fitting procedure we succeeded to separate the distinct Lorentzians assigned to more relevant types of motions: First relevant Lorentzian is clearly connected to the water diffusion motion in confined
