Fig. S7.

A graph in analogy to Fig. 4 but for different hydration pressures and a given decay length of 0.27 nm. With increasing pressures, the minima are shifted to higher ξ-values [compare with Fig. 5, sample 5 (i.e., the cresol system)] and progressively vanish. By contrast, with decreasing pressure, the minimum is shifted down to molecular dimensions, and there is a weak progressive transformation toward unstructured ternary fluids; The minimum corresponding to surfactant-free microemulsions appears at the “Lifshitz line” (65, 66), when hydration pressure is strong enough as tested by using octane/octanol as a mixed model solvent.
