Two triggers : Phase inversion of a particle‐stabilized oil–water system from an ordinary oil‐in‐water emulsion (see picture, left; green: oil, pink: water) to a water‐in‐oil high‐internal‐phase emulsion (right) at a fixed oil/water ratio (27:73 vol %) can be simply driven by either a change of pH value or salt concentration in a single system. Scale bars: 30 μm.
