Multiple emulsions and Pickering emulsions
Microfluidics and Formulation Emulsions and complex colloidal systems

Multiple emulsions are emulsions in which the dispersed phase is itself made up of drops (these drops can contain other drops up to an order "n"). Thus, a multiple emulsion of order 2 is a so-called double emulsion, which can be either an E ₁ /H/E ₂ emulsion if the continuous phase is water or an H ₁ /E/H ₂ emulsion if the continuous phase is oil. The double emulsion E ₁ /H/E ₂ can also be seen as two aqueous phases separated by an oily intermediate phase, a kind of "membrane" that can be used...
