Abstract:  The phenomenon of adsorption of colloidal particles at interfaces to stabilize the emulsions has been known for more than a century. Today, particle-stabilized emulsions, or so-called Pickering emulsions are receiving growing attention in the scientific and industrial communities. This presentation will summarize the general principles used in the assembly of colloidal particles at liquid interfaces. In particular, I will discuss the physical behavior of colloidal particles trapped at the interfaces and address that Pickering emulsions can serve as a template for the fabrication of novel functional materials which will have a great potential for applying in a variety of applications.
