Correlations and forces in sheared fluids with or without quenching
Christian M. Rohwer, Anna Maciolek, S. Dietrich +1
Spatial correlations play an important role in characterizing material properties related to non-local effects. Inter alia, they can give rise to fluctuation-induced forces. Equili…
Effective squirmer models for self-phoretic chemically active spherical colloids
M. N. Popescu, W. E. Uspal, Z. Eskandari +2
Various aspects of self-motility of chemically active colloids in Newtonian fluids can be captured by simple models for their chemical activity plus a phoretic slip hydrodynamic bo…
Shape-dependent guidance of active Janus particles by chemically patterned surfaces
W. E. Uspal, M. N. Popescu, M. Tasinkevych +1
Self-phoretic Janus particles move by inducing -- via non-equilibrium chemical reactions occurring on their surfaces -- changes in the chemical composition of the solution in which…
Smectic phases in ionic liquid crystals
Hendrik Bartsch, Markus Bier, Siegfried Dietrich
Ionic liquid crystals (ILCs) are anisotropic mesogenic molecules which carry charges and therefore combine properties of liquid crystals, e.g., the formation of mesophases, and of…
Guiding catalytically active particles with chemically patterned surfaces
W. E. Uspal, M. N. Popescu, S. Dietrich +1
Catalytically active Janus particles suspended in solution create gradients in the chemical composition of the solution along their surfaces, as well as along any nearby container…
Active colloids at fluid interfaces
P. Malgaretti, M. N. Popescu, S. Dietrich
If an active Janus particle is trapped at the interface between a liquid and a fluid, its self-propelled motion along the interface is affected by a net torque on the particle due…
