a and b SANS curves of multilamellar vesicles in excess water made of DP-DGTS (blue symbols, scaled by 10) and DPPC lipids (red symbols) in gel phase (a) (T = 19.3 °C) or in fluid phase (b) (T = 47.5 °C). c Lamellar period of DP-DGTS and DPPC as a function of temperature. For DPPC the two phase transition temperatures are directly deduced from the sharp period changes and represented by the vertical dashed lines. For DP-DGTS, where no sharp change is observed the dashed line corresponds to the gel-fluid transition temperature (43.8 °C) obtained by DSC (Fig. 1). No ripple phase Pβ was detected for DP-DGTS bilayers
