Proton fluctuations and water diffusion in dextran chemical hydrogels studied by incoherent elastic and quasielastic neutron scattering

Proton fluctuations reporting local motions of the glycosidic linkages of chemically crosslinked dextran hydrogels with well defined pore-size distribution are studied by static and dynamic neutron scattering approaches. The dependence of the dynamic behaviour of water on the pore sizes is also discussed. (c) 2005 Elsevier Ltd. All rights reserved.
