Abstract

Colloids are interesting systems, owing to intriguing and rich physics they display. In these soft systems,a variety of forces work at different length scales, to put colloidal particles together. During the talk, I will briefly introduce 'self assembly' process taking place in different colloidal systems and forces responsible for it. Van der Waals, electrostatic, hydrodynamic, and capillary forces, as well as Brownian motions will be discussed in the contest of colloidal self assembly. I will also concisely discuss the evaporative self-assembly process in sessile drops of colloids, and the physics of coffee-ring formation.
