Dynamics and Collapse of Two-Dimensional Colloidal Lattices Sowmitri Tarimala, Chih-yuan Wu, and Lenore L. Dai* Department of Chemical Engineering, Texas Tech UniVersity, MS 3121, Lubbock, Texas 79409 ReceiVed March 22, 2006. In Final Form: June 20, 2006 One interesting aspect of colloidal particles is the formation of colloidal crystals at the 2D and 3D levels. Here we report the dynamics and collapse of colloidal lattices at liquid-liquid interfaces using Pickering emulsions as an experimental template. The colloidal particles oscillate around their equilibrium positions. The short-time diffusion constant (
