Binary mixtures of rod-like colloids
In this work we investigate the shear induced instabilities occurring in colloidal binary mixtures of rigid anisotropic particles. To this end, we derive a theoretical framework including equilibrium and non-equilibrium methods. The equilibrium description is derived on the basis of microscopic …

Synthesis and Crystallization of Anisotropic Polymer Colloids
… methods are presented to synthesize polymer colloids with chemical and shape anisotropy. Two types of particles consisting of interpenetrating spheres, or dicolloids, are synthesized with length scales varying from approximately 300 nm to roughly 1.2 microm. For the first type of dicolloid, …

Coffee-Rings and Glasses: Colloids Out of Equilibrium
This thesis describes experiments that utilize colloids to explore nonequilibrium phenomena. Specifically, the deposition of particles during evaporation and the glass transition are explored. In the first set of experiments, we found that particle shape has a profound effect on particle …

Effect of boiling on deposition of metallic colloids
… Pool boiling experiments with dilute metallic colloids have been conducted to investigate several parameters impacting the system. The experimental data available in the literature is obtained by flow experiments, which do not help in correlating boiling mechanism with the deposition amount or …

Collective behavior of driven Janus colloids in external fields
Colloids are micron-sized particles widely used in industrial processes and everyday products. Conventional interest has focused on their equilibrium self-assembly structures by engineering static interactions between the colloids. The introduction of the fourth dimension, time, gives rise to a new …
