Abstract: The high energy resolution of Neutron Spin Echo (NSE) Spectroscopy is perfectly suited for studying thermally driven membrane fluctuations in soft matter systems. Measuring membrane fluctuations allows determining the membrane bare bending rigidity of a membrane patch and is complementary to phase diagram measurements and Small Angle Neutron Scattering (SANS). The different aspects investigated with these three techniques will be elaborated, and some examples of how changes of the membrane composition will affect its elasticity. A recent topic in microemulsion membrane dynamics is the influence of a rigid interface to the surfactant membrane. Studies under grazing incidence conditions give a detailed insight into the effect of the interface to membrane elasticity.
