Figure 7
Time-resolved GIWAXS q_z-cuts (frame time 10 min) before (black curve) and during hydration (water flux 13.0 g h⁻¹, colored curves) of the phospholipid DMPC. The curves are shifted upwards for better visibility. The gap around 0.35 Å⁻¹ corresponds to the dead stripes of the used Pilatus 300k detector. The graph displays first- and second-order Bragg peaks corresponding to the bilayer stacking. Each diffraction order is split into two peaks, due to scattering of the direct beam (labeled D), and scattering of the reflected beam (labeled R). The dashed line marks the peak position for the scattering of the direct beam when the layers are fully hydrated. After 30 min until full hydration is reached after around 700 min the sample is in a bimodal state consisting of a state with lower (labeled $[\bullet]$ ) and one with higher hydration (labeled *).
