In this work, we review the physics of the liquid ejection by the application of electric fields,
paying special attention to the steady cone-jet mode of electrospray. We aim to provide a …

Dielectrophoresis (DEP) is a selective electrokinetic particle manipulation technology that is
applied for almost 100 years and currently finds most applications in biomedical research …

We study the active dynamics of self-propelled asymmetrical colloidal particles (Janus
particles) fueled by an AC electricfield. Both the speed and direction of the self-propulsion …

Despite the mounting interest in synthetic active particles, too little is known about their
assembly into higher‐order clusters. Here, mixing bare silica particles with Janus particles …

Exploitation of the intrinsic electrical properties of particles has recently emerged as an
appealing approach for trap** and separating various scaled particles. Initiative particle …

Field-directed colloidal assembly has shown remarkable recent progress in increasing the
complexity, degree of control, and multiscale organization of the structures. This has largely …

This paper reviews both theory and experimental observation of the AC electrokinetic
properties of conducting microparticles suspended in an aqueous electrolyte. Applied AC …

Position-controllable trap** of particles on the surface of a bipolar metal strip by induced-
charge electroosmotic (ICEO) flow is presented herein. We demonstrate a nonlinear ICEO …

Hypothesis The synthesis of compositionally heterogeneous particles is central to the
development of complex colloidal units for self-assembly and self-propulsion. Yet, as the …

Hypothesis The interaction of active particles with walls can explain discrepancies between
experiments and theory derived for particles in the bulk. For an electric field driven …
