Dynamics of collagen hydration by quasielastic neutron scattering

Dynamics of collagen hydration by quasielastic neutron scattering

QENS spectra from 52% H 2O-hydrated collagen fibres ( T=276–321 K) were modelled by three-component scattering laws including small central peak broadenings. These give diffusion coefficients for mobile H 2O of ∼5×10 −6 cm 2/s, with activation energy ∼2 kcal/mol. The broad components relate to local...

Zusammenfassung:QENS spectra from 52% H 2O-hydrated collagen fibres ( T=276–321 K) were modelled by three-component scattering laws including small central peak broadenings. These give diffusion coefficients for mobile H 2O of ∼5×10 −6 cm 2/s, with activation energy ∼2 kcal/mol. The broad components relate to localised modes.
