Single microparticle electrophoresis to study polymer and nanoparticle adsorption
De wetenschappelijke interesse voor colloïdale deeltjes en de interactie van colloïdale deeltjes met andere micro- en nano-objecten (bvb nanodeeltjes, eiwitten of polymeren) is belangrijk in industriële processen en in farmaceutische toepassingen. Om verschijnselen waarbij colloïdale deeltjes …

Structural properties and phase behavior in colloidal suspensions
… systems. Specifically, in Chapter 2 I study nanoparticle haloing in a system of silica microspheres and highly charged polystyrene nanoparticles. Computer simulations are employed to determine the effective microsphere– microsphere potential induced by the nanoparticles. From these …

Nanoparticle Engineering of Colloidal Suspension Behavior
We investigate the effects of highly charged nanoparticles on the phase behavior, structure, and assembly of colloidal microsphere suspensions. Specifically, by selectively tuning the electrostatic interactions between silica microspheres and polystyrene nanoparticles, we study the behavior of four …

Stabilization of weakly charged microparticles using highly charged nanoparticles
… the possible use of highly-charged spherical nanoparticles to stabilize an aqueous dispersion of weakly-charged microspheres. At low pH values, the surface of silica is weakly charged, which leads to flocculation of colloidal suspensions of silica microspheres. Binary solutions of weakly …

Controlling Colloidal Stability using Highly Charged Nanoparticles
… focused on the potential use of highly charged nanoparticles to stabilize dispersions of weakly charged microparticles. The experimental components of the project centered on a model colloidal system containing silica microparticles at the isoelectric point where the suspensions are unstable and …
