Structure of electrolyte solutions at non-uniformly charged surfaces on a variety of length scales
Markus Bier, Maximilian Mußotter, S. Dietrich
The structures of dilute electrolyte solutions close to non-uniformly charged planar substrates are systematically studied within the entire spectrum of microscopic to macroscopic…
Intrusion of liquids into liquid infused surfaces with nanoscale roughness
Swarn Lata Singh, Lothar Schimmele, S. Dietrich
We present a theoretical study of the intrusion of an ambient liquid into pores of a nano-corrugated wall w. The pores are prefilled with a liquid lubricant which adheres to the wa…
Wetting behavior of a colloidal particle trapped at a composite liquid-vapor interface of a binary liquid mixture
Hyojeong Kim, Lothar Schimmele, S. Dietrich
A partially miscible binary liquid mixture, composed of A and B particles, is considered theoretically under conditions for which a stable A-rich liquid phase is in thermal equilib…
Self-motility of an active particle induced by correlations in the surrounding solution
Alvaro Domínguez, M. N. Popescu, C. M. Rohwer +1
Current models of phoretic transport rely on molecular forces creating a "diffuse" particle-fluid interface. We investigate theoretically an alternative mechanism, in which a diffu…
The role of counterions in ionic liquid crystals
Hendrik Bartsch, Markus Bier, S. Dietrich
Previous theoretical studies of calamitic (i.e., rod-like) ionic liquid crystals (ILCs) based on an effective one-species model led to indications of a novel smectic-A phase with a…
Transient coarsening and the motility of optically heated Janus colloids in a binary liquid mixture
Juan Ruben Gomez-Solano, Sutapa Roy, Takeaki Araki +2
A gold-capped Janus particle suspended in a near-critical binary liquid mixture can self-propel under illumination. We have immobilized such a particle in a narrow channel and stud…
Bridging transitions and capillary forces for colloids in a slit
Oleg A. Vasilyev, Marcel Labbé-Laurent, S. Dietrich +1
Capillary bridges can form between colloids immersed in a two phase fluid, e.g., in a binary liquid mixture, if the surface of the colloids prefers the species other than the one f…
Heterogeneous surface charge confining an electrolyte solution
Maximilian Mußotter, Markus Bier, S. Dietrich
The structure of dilute electrolyte solutions close to a surface carrying a spatially inhomogeneous surface charge distribution is investigated by means of classical density functi…
Floor- or ceiling-sliding for chemically active, gyrotactic, sedimenting Janus particles
Sayan Das, Zohreh Jalilvand, Mihail N. Popescu +3
Surface bound catalytic chemical reactions self-propel chemically active Janus particles. In the vicinity of boundaries, these particles exhibit rich behavior, such as the occurren…
Wetting of soft substrates
M. Napiórkowski, L. Schimmele, S. Dietrich
Within mean-field theory we study wetting of elastic substrates. Our analysis is based on a grand canonical free energy functional of the fluid number density and of the substrate…
Current-mediated synchronization of a pair of beating non-identical flagella
V. Dotsenko, A. Maciolek, G. Oshanin +2
The basic phenomenology of experimentally observed synchronization (i.e., a stochastic phase locking) of identical, beating flagella of a biflagellate alga is known to be captured…
Interface structures in ionic liquid crystals
Hendrik Bartsch, Markus Bier, S. Dietrich
Ionic liquid crystals (ILCs) are anisotropic mesogenic molecules which additionally carry charges. This combination gives rise to a complex interplay of the underlying (anisotropic…
Ferronematics in confinement
Grigorii Zarubin, Markus Bier, Siegfried Dietrich
The behavior of a uniformly magnetized ferronematic slab is investigated numerically in a situation in which an external magnetic field is applied parallel and antiparallel, respec…

Using mesoscopic numerical simulations and analytical theory we investigate the coarsening of the solvent structure around a colloidal particle emerging after a temperature quench…
Collective behavior of colloids due to critical Casimir interactions
Anna Maciolek, Siegfried Dietrich
If colloidal solute particles are suspended in a solvent close to its critical point, they act as cavities in a fluctuating medium and thereby restrict and modify the fluctuation s…
Electrolyte solutions at curved electrodes. II. Microscopic approach
Andreas Reindl, Markus Bier, S. Dietrich
Density functional theory is used to describe electrolyte solutions in contact with electrodes of planar or spherical shape. For the electrolyte solutions we consider the so-called…
Collective dynamics of chemically active particles trapped at a fluid interface
Alvaro Domínguez, P. Malgaretti, M. N. Popescu +1
Chemically active colloids generate changes in the chemical composition of their surrounding solution and thereby induce flows in the ambient fluid which affect their dynamical evo…
