Complex Formation between Polyelectrolytes and Oppositely Charged Oligoelectrolytes
Jiajia Zhou, Matthias Barz, Friederike Schmid
We study the complex formation between one long polyanion chain and many short oligocation chains by computer simulations. We employ a coarse-grained bead-spring model for the poly…
Computer simulations of single particles in external electric fields
Jiajia Zhou, Friederike Schmid
Applying electric fields is an attractive way to control and manipulate single particles or molecules, e.g., in lab-on-a-chip devices. However, the response of nanosize objects in…
An efficient dissipative particle dynamics-based algorithm for simulating electrolyte solutions
Stefan Medina, Jiajia Zhou, Zhen-Gang Wang +1
We propose an efficient simulation algorithm based on the dissipative particle dynamics (DPD) method for studying electrohydrodynamic phenomena in electrolyte fluids. The fluid flo…
Flows and mixing in channels with misaligned superhydrophobic walls
Tatiana V. Nizkaya, Evgeny S. Asmolov, Jiajia Zhou +2
Aligned superhydrophobic surfaces with the same texture orientation reduce drag in the channel and generate secondary flows transverse to the direction of the applied pressure grad…
Computer Simulations of Charged Colloids in Alternating Electric Fields
Jiajia Zhou, Friederike Schmid
We briefly review recent theoretical and simulation studies of charged colloidal dispersions in alternating electric fields (AC fields). The response of single colloid to an extern…
A Dissipative-Particle-Dynamics Model for Simulating Dynamics of Charged Colloid
Jiajia Zhou, Friederike Schmid
A mesoscopic colloid model is developed in which a spherical colloid is represented by many interacting sites on its surface. The hydrodynamic interactions with thermal fluctuation…
Effective slippage on superhydrophobic trapezoidal grooves
Jiajia Zhou, Evgeny S. Asmolov, Friederike Schmid +1
We study the effective slippage on superhydrophobic grooves with trapezoidal cross-sections of various geometries (including the limiting cases of triangles and rectangular stripes…
Dynamic and Dielectric Response of Charged Colloids in Electrolyte Solutions to External Electric Fields
Jiajia Zhou, Roman Schmitz, Burkard Duenweg +1
Computer simulations are used to investigate the response of a charged colloid and its surrounding microion cloud to an external electric field. Both static fields (DC) and alterna…
AC-field-induced Polarization for Uncharged Colloids in Salt Solution: A Dissipative Particle Dynamics Simulation
Jiajia Zhou, Friederike Schmid
We study the response of a spherical colloid under alternating electric fields (AC-fields) by mesoscopic simulation method, accounting in full for hydrodynamic and electrostatic in…
Effective slip-length tensor for a flow over weakly slipping stripes
Evgeny S. Asmolov, Jiajia Zhou, Friederike Schmid +1
We discuss the flow past a flat heterogeneous solid surface decorated by slipping stripes. The spatially varying slip length, , is assumed to be small compared to the scale o…
Anisotropic flow in striped superhydrophobic channels
Jiajia Zhou, Aleksey V. Belyaev, Friederike Schmid +1
We report results of dissipative particle dynamics simulations and develop a semi-analytical theory of an anisotropic flow in a parallel-plate channel with two superhydrophobic str…
Dielectric Response of Nanoscopic Spherical Colloids in Alternating Electric Fields: A Dissipative Particle Dynamics Simulation
Jiajia Zhou, Friederike Schmid
We study the response of single nanosized spherical colloids in electrolyte solution to an alternating electric field (AC field) by computer simulations. We use a coarse-grained me…
