Primitive Model Electrolytes in the Near and Far Field: Decay Lengths from DFT and Simulations
P. Cats, R. Evans, A. Härtel +1
Inspired by recent experimental observations of anomalously large decay lengths in concentrated electrolytes, we revisit the Restricted Primitive Model (RPM) for an aqueous electro…
Flow-induced surface charge heterogeneity in electrokinetics due to Stern-layer conductance coupled to reaction kinetics
B. L. Werkhoven, J. C. Everts, S. Samin +1
We theoretically study the electrokinetic problem of a pressure-induced liquid flow through a narrow long channel with charged walls, going beyond the classical Helmholtz-Schmoluko…
Calculating the motion of highly confined, arbitrary-shaped particles in Hele-Shaw channels
Bram Bet, Rumen Georgiev, William Uspal +3
We combine theory, numerical calculations, and experiments to accurately predict the motion of anisotropic particles in shallow microfluidic channels, in which the particles are st…
A Landau-de Gennes theory for hard colloidal rods: defects and tactoids
Jeffrey Everts, Melle Punter, Sela Samin +2
We construct a phenomenological Landau-de Gennes theory for hard colloidal rods by performing an order parameter expansion of the chemical-potential dependent grand potential. By f…
The isotropic-nematic interface in suspensions of hard rods: Mean-field properties and capillary waves
S. Wolfsheimer, C. Tanase, K. Shundyak +2
We present a study of the isotropic-nematic interface in a system of hard spherocylinders. First we compare results from Monte Carlo simulations and Onsager density functional theo…
Extended sedimentation profiles in charged colloids: the gravitational length, entropy, and electrostatics
C. P. Royall, R. van Roij, A. van Blaaderen
We have measured equilibrium sedimentation profiles in a colloidal model system with confocal microscopy. By tuning the interactions, we have determined the gravitational length in…
