Abstract:
... Emulsions stabilized with solid particles (Pickering emulsions) are known for their long-term static stability, which is typically defined by the lack of macroscopic coalescence with respect to time. This is attributed to the irreversible adsorption of particles to the oil/water interface, which provides a physical barrier to droplet coalescence. However, because there are so many particle emulsif ...
