Abstract:
　　Classical approach accounting for ionic colloids (ICs) was established in the 40’s by the joint effort of Derjaguin & Landau and Verwey & Overbeek; known as DLVO theory. Though successful in explaining stability of ICs the DLVO addresses half story, namely the interplay between attractive and repulsive interaction among the colloidal particles, given the surface charge density (σ). Nevertheless, while calculating “σ” the DLVO approach does not include key aspects of as-suspended colloidal particles, such as shape, size, charge-exchange, and nature. The quantum approach was successfully introduced to cover these important gaps and it will be summarized in the talk.
