This review presents the recent progress in the development of active particles driven by
alternating-current (AC) electrokinetic effects. These particles propel by asymmetrically …

Recent experimental studies have utilized AC electric fields and electrochemical reactions in
multicomponent electrolyte solutions to control colloidal assembly. However, theoretical …

We demonstrate that application of an oscillatory electric field to a liquid yields a long-range
steady field, provided the ions present have unequal mobilities. The main physics is …

Controlled colloidal levitation is key to many applications. Recently, it was discovered that
polymer microspheres were levitated to a few micrometers in aqueous solutions in …

In this paper, building upon the numerical discovery of asymmetric rectified electric fields
(AREFs), we explore the generation of AREF by applying a sawtooth-like voltage to 1: 1 …

Recent experiments [SH Hashemi et al., Phys. Rev. Lett., 2018, 121, 185504] have shown
that a long-ranged steady electric field emerges when applying an oscillating voltage over …

Two oppositely charged surfaces separated by a dielectric medium attract each other. In
contrast we observe a strong repulsion between two plates of a capacitor that is filled with an …

We explore the force generation and surface interactions arising when electric fields are
applied across fluid films. Using a surface force balance (SFB) we measure directly the force …

Many industrial processes generate “oily wastewaters”, characterized by low volume
fractions of micrometer-scale, oil-in-water droplets that are difficult to separate by …

A dielectric drop suspended in conducting liquid and subjected to a uniform electric field
deforms into an ellipsoid whose major axis is either perpendicular or tilted (because of the …
