Description

This lecture covers the direct assembly of particles on solid surfaces, focusing on the Marangoni effect as a driving force for particle motion and evaporation. It discusses the formation of coffee ring patterns, the use of surfactants and anisotropic particles to overcome this effect, and the assembly of colloids on solid surfaces. The Langmuir-Blodgett experiment is presented as a method for creating well-defined monolayers of particles. The lecture also explores the formation of colloidal crystals and agglomeration processes, including diffusion-limited and reaction-limited agglomeration. Depletion forces, agglomeration mechanisms, and their applications are discussed.
