Optimality in superselective surface binding by multivalent DNA nanostars
Christine Linne, Eva Heemskerk, Jos Zwanikken +2
Weak multivalent interactions govern a large variety of biological processes like cell-cell adhesion and virus-host interactions. These systems distinguish sharply between surfaces…
Ion association in low-polarity solvents: comparisons between theory, simulation, and experiment
Chantal Valeriani, Philip J. Camp, Jos W. Zwanikken +2
The association of ions in electrolyte solutions at very low concentration and low temperature is studied using computer simulations and quasi-chemical ion-pairing theory. The spec…
Computer simulations of the restricted primitive model at very low temperature and density
Chantal Valeriani, Philip J. Camp, Jos W. Zwanikken +2
The problem of successfully simulating ionic fluids at low temperature and low density states is well known in the simulation literature: using conventional methods, the system is…
Inflation of the screening length induced by Bjerrum pairs
Jos Zwanikken, René van Roij
Within a modified Poisson-Boltzmann theory we study the effect of Bjerrum pairs on the typical length scale over which electric fields are screened in electrolyte solutio…
Stability of additive-free water-in-oil emulsions
Jos Zwanikken, Joost de Graaf, Markus Bier +1
We calculate ion distributions near a planar oil-water interface within non-linear Poisson-Boltzmann theory, taking into account the Born self-energy of the ions in the two media.…
Curvature dependence of the electrolytic liquid-liquid interfacial tension
Markus Bier, Joost de Graaf, Jos Zwanikken +1
The interfacial tension of a liquid droplet surrounded by another liquid in the presence of microscopic ions is studied as a function of the droplet radius. An analytical expressio…
Spontaneous Charging and Crystallization of Water Droplets in Oil
Joost de Graaf, Jos Zwanikken, Markus Bier +4
We study the spontaneous charging and the crystallization of spherical micron-sized water-droplets dispersed in oil by numerically solving, within a Poisson-Boltzmann theory in the…
Liquid-liquid interfacial tension of electrolyte solutions
Markus Bier, Jos Zwanikken, Rene van Roij
It is theoretically shown that the excess liquid-liquid interfacial tension between two electrolyte solutions as a function of the ionic strength I behaves asymptotically as O(- I^…
Destructed double-layer and ionic charge separation near the oil-water interface
Jos Zwanikken, René van Roij
We study suspensions of hydrophobic charged colloidal spheres dispersed in a demixed oil-water mixture by means of a modified Poisson-Boltzmann theory, taking into account image ch…
Sedimentation of binary mixtures of like- and oppositely charged colloids: the primitive model or effective pair potentials?
M. Dijkstra, J. Zwanikken, R. van Roij
We study sedimentation equilibrium of low-salt suspensions of binary mixtures of charged colloids, both by Monte Carlo simulations of an effective colloids-only system and by Poiss…
The sediment of mixtures of charged colloids: segregation and inhomogeneous electric fields
Jos Zwanikken, rene van Roij
We theoretically study sedimentation-diffusion equilibrium of dilute binary, ternary, and polydisperse mixtures of colloidal particles with different buoyant masses and/or charges.…
