000849991 520__ $$aSoyPC membrane stack modes adjacent to a hard hydrophilic wall were observed to be of viscoelastic character on nanosecond time scales [1]. This is astonishing because nearly all soft matter systems display over-damped behavior on nanosecond time scales, because the molecular friction is rather strong. This has direct impact on energy dissipation along the membrane, because shock energies could be distributed over larger areas as classically into the volume in the normal direction. Membrane stacks in mammalian joints could benefit from that effect.We started to observe soyPC membrane stacks in terms of structure using grazing incidence small angle neutron scattering. These systems we doped with ibuprofen [2] molecules to observe the malfunction of the membrane. Ibuprofen is known to cause stomach bleeding upon extensive use.The pure membranes in water were studied using grazing incidence neutron spin echo spectroscopy. One drawback of this method is the weak scattering intensity resulting from small scattering volumes next to the solid-liquid interface and from the small apertures that are needed to define the incident angle well. A neutron resonator [3] was developed to enhance the impinging wave-field dramatically such that neutron spectroscopy at interfaces becomes feasible.References[1] S. Jaksch, O. Holderer, M.
