Tunable interactions between colloidal particles in external conically rotating electric fields
are calculated, while the (vertical) axis of the field rotation is normal to the (horizontal) …

The ion distribution of electrolytes near interfaces with dielectric contrast has important
consequences for electrochemical processes and many other applications. To date, most …

Manipulation of particles at the surface of a droplet can lead to the formation of structures
with heterogeneous surfaces, including patchy colloidal capsules or patchy particles. Here …

A variety of electrostatic phenomena, including the structure of electric double layers and the
aggregation of charged colloids and proteins, are affected by nonuniform electric permittivity …

Spherical Janus colloids, particles with different surface properties on their two
hemispheres, are generally heterogeneous in permittivity. This dielectric heterogeneity may …

Self-propelled colloidal swimmers move by pushing the adjacent fluid backwards. The
resulting motion of an asymmetric body depends on the profile of pushing velocity over its …
