Input (English): Otto Stern proposed a slipping plane in these systems, at which ions with non-negligible volume adsorb to a surface, modifying the Helmholtz and Gouy-Chapman models. These systems are stabilized through the addition of a salt, called peptization. Because these materials effectively scatter light with low wavelengths, they often appear blue when light is shined through them in the Tyndall effect. Flocculation disrupts these systems, which are defined to be dispersions with particle diameter between a nanometer and a micrometer. For 10 points, name these systems of in which one substance is dispersed throughout another, exemplified by foams, emulsions, and aerosols.
Output (English): Science
