## Abstract The alignment and the aggregation of particles in a viscoelastic fluid in simple shear flow are qualitatively analyzed using a twoβdimensional direct numerical simulation. Depending on the shear thinning, solvent viscosity, and Weissenburg number, a typical sequence in structural transi

Alternating adsorption of multivalent ions and oppositely charged polyelectrolytes on colloid particles has been investigated. Multilayer films composed of Tb 3+ /polysterene sulfonate (PSS) and 4-pyrene sulfate/polyallylamine (PAH) were successfully assembled on polysterene sulfonate (PS) and melam
When a dilute colloidal suspension of 50-Β΅m polyamide particles is exposed to a deformable interface, spontaneous flow occurs. This flow is orderly, reproducible, and shows a proportional dependence on particle concentration. The same type of flow was also observed in a silicon oil suspension. Placi
