Phase diagrams of water-OEA lipid system as obtained by combining CPOM and SAXS at 5.0% wt arginine. The blue dashed lines correspond to the SAXS results of water-OEA lipid system in presence of glucose solution at constant water/lipid ratio of 20.0 wt %, and concentration of glucose of 5.0% wt. The small letters a′, b′, and c′ across the blue dashed lines are given to distinguish the temperature intervals of the different cubic phases of water-OEA lipid system in presence of glucose solution. The three selected points A, B, and C located at 42.0°C in the phase diagram correspond to water/lipid ratios of 25.0, 50.0, and 100.0%, respectively (details are presented in the Discussion section).
