Dynamic clustering in active colloidal suspensions with chemical signaling
Dynamic cluster active colloidal suspensions chemical signaling
2012/2/29
In this paper, we explore experimentally the phase behavior of a dense active suspension of self- propelled colloids. In addition to a solid-like and a gas-like phase observed for high and low densiti...
Convection in colloidal suspensions with particle-concentration-dependent viscosity
colloidal suspensions particle-concentration-dependent viscosity
2010/4/6
The onset of thermal convection in a horizontal layer of a colloidal suspension is investigated in terms of a continuum model for binary-fluid mixtures where the viscosity depends on the local concent...
Ground-state shapes and structures of colloidal domains
Charged colloids Self-assembly Continuum model Phase diagram
2014/9/24
In charged colloidal suspensions, the competition between square-well attraction and long-range Yukawa repulsion leads to various stable domains and Wigner supercrystals. Using a continuum model and s...
Stability Analysis of Three-Dimensional Colloidal Domains: Quadratic Fluctuations
Stability Analysis Three-Dimensional Colloidal Domains Quadratic Fluctuations
2014/9/24
Three-dimensional domain patterns can self-assemble in a charged colloidal suspension with competing shortrange attraction and long-range Yukawa repulsion. Following the investigation of the ground-st...
High-Order Mode-Coupling Theory for the Colloidal Glass Transition
High-Order Mode-Coupling Theory Colloidal Glass Transition
2014/9/24
A theoretical approach is developed to derive a hierarchy of mode-coupling equations for the dynamics of concentrated colloidal suspensions, which improves the prediction of the colloidal glass transi...
