Discovery of bio-inspired, self-propelled and externally-powered nano-/micro-motors, rotors
and engines (micromachines) is considered a potentially revolutionary paradigm in …

Colloidal motors with micrometer dimensions and no moving parts can be propelled by self-
diffusiophoresis. Coupling between molecular concentration gradients generated by …

The phoretic mechanisms at stake in the propulsion of asymmetric colloids have been the
subject of debates during the past years. In particular, the importance of electrokinetic effects …

Despite mounting evidence that the same gradients, which active colloids use for swimming,
induce important cross-interactions (phoretic interactions), they are still ignored in most …

Self-driven micro/nanomotors (MNMs) can generate" on-the-fly" mass transfer, significantly
advancing micro/nanofluid technologies. However, the presence of at least one symmetric …

Collective motion in nonequilibrium steady state suspensions of self-propelled Janus motors
driven by chemical reactions can arise due to interactions coming from direct intermolecular …

Janus particles with the ability to move phoretically in self-generated chemical concentration
gradients are model systems for active matter. Their motion typically consists of straight …

In the presence of a chemically active particle, a nearby chemically inert particle can
respond to a concentration gradient and move by diffusiophoresis. The nature of the motion …

Active matter is an emerging area of interest but the broken symmetry necessary for motion
increases the complexity of mathematical modeling. However, these models can be critical …

An analytic framework is presented for calculating the self-induced thermophoretic velocity
of a laser-heated Janus metamaterial micro-particle, consisting of two conducting …
