From: X-ray and neutron investigation of self-assembled lipid layers on a titanium surface
X-ray reflectivity experiment. The round dots correspond to the uncoated titanium plate and the cubic dots to the OPA coated titanium plate. The beating point can be observed for both experimental curve at Qz = 0.27 Å-1. The corresponding scattering length density profiles of the fits are present in the upper right corner. The reflectivity curves are offset vertically for clarity. SLD profiles of the oxide and POPE region are shown with the TiO2/air or TiO2/OPA interface defined as zero to enlarge the difference between the models.
