Colloidal Particles at a Range of Fluid–Fluid Interfaces

Colloidal particles at liquid interfaces.

Capillary interactions between colloidal particles at curved fluid interfaces

Colloidal particles in liquid crystal films and at interfaces

This mini-review discusses the recent contribution of theoretical and computational physics as well as experimental efforts to the understanding of the behavior of colloidal particles in confined geometries and at liquid crystalline interfaces. Theoretical approaches used to study trapping, longand short-range interactions, and assembly of solid particles and liquid inclusions are outlined. As ...

A Microfluidic Approach to Chemically Driven Assembly of Colloidal Particles at Gas-Liquid Interfaces

Bubbles are everyday objects and easy to make? Not so, when one is trying to generate and maintain tiny bubbles with accurately defined volumes in the nanoliter range or even smaller. This follows from the fact that the gas/liquid interface (the bubble boundary) is energetically expensive. As a consequence, this interface has a tension g and the bubble has a spherical shape (with radius R), whi...

A microfluidic approach to chemically driven assembly of colloidal particles at gas-liquid interfaces.

Bubbling up: Dissolution of CO(2) bubbles in a suspension of colloidal particles chemically induces the assembly of particles on the surface of shrunken bubbles, and thus yields rapid continuous formation of a colloidal armor. This approach maintains the high colloidal stability of particles in bulk, has increased productivity, and allows the formation of bubbles with precisely controlled dimen...
