Inversion of particle-stabilized emulsions of partially miscible liquids by mild drying of modified silica particles

► For Pickering emulsions of water and lutidine mixtures with silica particles, the hydration of the particle surface causes a change in emulsion structure. ► For water and lutidine at critical composition, decreasing silica particle hydration inverts the emulsion. ► For silica particles with some amino surface groups, a bijel forms at inversion. ► The character of the silica surfaces can change during phase separation.
