Effective interactions, structure, and pressure in charge-stabilized colloidal suspensions: Critical assessment of charge renormalization methods
Mariano E. Brito, Gerhard Nägele, Alan R. Denton
Charge-stabilized colloidal suspensions display a rich variety of microstructural and thermodynamic properties, which are determined by electro-steric interactions between all ioni…
Clustering in quasi-two-dimensional dispersions of Brownian particles with competitive interactions: Phase diagram and structural properties
Zihan Tan, Vania Calandrini, Jan K. G. Dhont +1
Competing short-range attractive (SA) and long range repulsive (LR) interactions have been invoked to describe colloid or protein solutions, as well as membrane proteins interactio…
Hydrodynamics of Immiscible Binary Fluids with Viscosity Contrast: A multiparticle collision dynamics approach
Zihan Tan, Vania Calandrini, Jan K. G. Dhont +2
We present a multiparticle collision dynamics (MPC) implementation of layered immiscible fluids and of different shear viscosities separated by planar interfaces. The simul…
Modeling deswelling, thermodynamics, structure, and dynamics in ionic microgel suspensions
Mariano E. Brito, Alan R. Denton, Gerhard Nägele
Ionic microgel particles in a good solvent swell to an equilibrium size determined by a balance of electrostatic and elastic forces. When crowded, ionic microgels deswell owing to…
Short- and long-time diffusion, and dynamic scaling in suspensions of charged colloidal particles
Adolfo J. Banchio, Marco Heinen, Peter Holmqvist +1
We report on a comprehensive theory-simulation-experimental study of collective and self-diffusion in suspensions of charge-stabilized colloidal spheres. In simulation and theory,…
Ultrafiltration of charge-stabilized dispersions at low salinity

We present a comprehensive study of cross-flow ultrafiltration (UF) of charge-stabilized suspensions, under low-salinity conditions of electrostatically strongly repelling colloida…
Ultrafiltration modeling of non-ionic microgels
Rafael Roa, Emiliy K. Zholkovskiy, Gerhard Nägele
Membrane ultrafiltration (UF) is a pressure driven process allowing for the separation and enrichment of protein solutions and dispersions of nanosized microgel particles. The perm…
Dynamics of suspensions of hydrodynamically structured particles: Analytic theory and experiment
Jonas Riest, Thomas Eckert, Walter Richtering +1
We present an easy-to-use analytic toolbox for the calculation of short-time transport properties of concentrated suspensions of spherical colloidal particles with internal hydrody…
Electrokinetic and hydrodynamic properties of charged-particles systems: From small electrolyte ions to large colloids
G. Nägele, M. Heinen, A. J. Banchio +1
Dynamic processes in dispersions of charged spherical particles are of importance both in fundamental science, and in technical and bio-medical applications. There exists a large v…
Effect of glycerol and dimethyl sulfoxide on the phase behavior of lysozyme: Theory and experiments
Christoph Gögelein, Dana Wagner, Frédéric Cardinaux +2
Salt, glycerol and dimethyl sulfoxide (DMSO) are used to modify the properties of protein solutions. We experimentally determined the effect of these additives on the phase behavio…
Dynamics of charged gibbsite platelets in the isotropic phase
