Desorption as a rate limiting step for gas permeation through a polymer membrane

Article Abstract:

Permeation of gases through polymer membranes is not adequately represented by classic diffusion theory under certain conditions. Gas transfer through wetted membranes is an important process in many applied engineering, chemical, and biological systems and is observed that kinetic limitations at the surface of a wetted membrane can greatly diminish the rate of gas permeation.

Interactions of hydration water and biological membranes studied by neutron scattering

Article Abstract:

Neutron scattering technique has been used to study structural and dynamical properties of hydration water and its influence on the behavior of halobacteria purple membranes. Results demonstrate the effect of hydration process on the membrane properties.
