Differently from passive Brownian particles, active particles, also known as self-propelled
Brownian particles or microswimmers and nanoswimmers, are capable of taking up energy …

▪ Abstract Development and optimization of multifunctional devices for fluidic manipulation of
films, drops, and bubbles require detailed understanding of interfacial phenomena and …

Using light to control liquid motion is a new paradigm for the actuation of microfluidic
systems. We review here the different principles and strategies to induce or control liquid …

The chemotactic movement of decanol droplets in aqueous solutions of sodium decanoate
in response to concentration gradients of NaCl has been investigated. Key parameters of the …

We experimentally study the motion of light-activated colloidal microswimmers in a
viscoelastic fluid. We find that, in such a non-Newtonian environment, the active colloids …

This review explores the intersection between two important fields of colloid and interface
science–that of active colloidal particles and of (passive) particles at fluid-fluid interfaces …

An alcohol (pentanol) droplet exhibits spontaneous motion on an aqueous solution, driven
by a solutal Marangoni effect. We found that the droplet's mode of motion is controlled by its …

The interfacial convection in multilayer systems is a widespread phenomenon that is of great
importance in numerous branches of technology, including chemical engineering, space …

Adjusting the wetting properties of water through the addition of a miscible liquid is
commonly used in a wide variety of industrial processes involving interfaces. We investigate …

The development of self-propelled motors that mimic biological motors is an important
challenge for the transport of either themselves or some material in a small space, since …
