Anomalous system-size dependence of electrolytic cells with an electrified oil-water interface
Marise J. E. Westbroek, Niels Boon, René van Roij
Manipulation of the charge of the dielectric interface between two bulk liquids not only enables the adjustment of the interfacial tension but also controls the storage capacity of…
Density-induced reentrant melting of colloidal Wigner crystals
Jeffrey Everts, Niels Boon, René van Roij
Electrostatic repulsions can drive crystallization in many-particle systems. For charged colloidal systems, the phase boundaries as well as crystal structure are highly tunable by…
Effective charges and virial pressure of concentrated macroion solutions
Niels Boon, Guillermo Ivan Guerrero-Garcia, Rene van Roij +1
The stability of colloidal suspensions is crucial in a wide variety of processes including the fabrication of photonic materials and scaffolds for biological assemblies. The ionic…
Electrostatic Interactions between Janus Particles
Joost de Graaf, Niels Boon, Marjolein Dijkstra +1
In this paper we study the electrostatic properties of `Janus' spheres with unequal charge densities on both hemispheres. We introduce a method to compare primitive-model Monte Car…
Charge regulation and ionic screening of patchy surfaces
Niels Boon, René van Roij
The properties of surfaces with charge-regulated patches are studied using non-linear Poisson-Boltzmann theory. Using a mode expansion to solve the non-linear problem efficiently,…
Phase diagrams of colloidal spheres with a constant zeta-potential
Frank Smallenburg, Niels Boon, Maarten Kater +2
We study suspensions of colloidal spheres with a constant zeta-potential within Poisson-Boltzmann theory, quantifying the discharging of the spheres with increasing colloid density…
Screening of heterogeneous surfaces: charge renormalization of Janus particles
N. Boon, E. Carvajal Gallardo, S. Zheng +3
Nonlinear ionic screening theory for heterogeneously charged spheres is developed in terms of a mode-decomposition of the surface charge. A far-field analysis of the resulting elec…
