Self-propelling particles or microswimmers have opened a new field of investigation with
both fundamental and practical perspectives. They represent very convenient model objects …

Confinement increases contacts between microswimmers in dilute suspensions and affects
their interactions. In particular, boundaries have been shown experimentally to lead to the …

Chemically active colloids modify the concentration of chemical solutes surrounding them in
order to self-propel. In doing so, they generate long-ranged hydrodynamic flows and …

Particle agglomeration is relevant to numerous industrial applications and consumer
products. The present work explores interactions between and agglomeration of gamma (γ) …

Similarly to their biological counterparts, suspensions of chemically active autophoretic
swimmers exhibit a non-trivial dynamics involving self-organisation processes as a result of …

Janus phoretic particles exploit chemical energy stored in their environment to produce
mechanical work on the surrounding fluid and self-propel. These active particles modify and …

Driven by the necessity to achieve a thorough comprehension of the bottom-up fabrication
process of functional materials, this experimental study investigates the pairwise interactions …

Chemically active droplets display complex self‐propulsion behavior in homogeneous
surfactant solutions, often influenced by the interplay between diffusiophoresis and …

Many biological microswimmers are capable of chemotaxis, ie, they can sense an ambient
chemical gradient and adjust their mechanism of motility to move towards or away from the …

Janus particles are a class of artificial swimmers with an anisotropic coverage of catalyst on
its surface. This generates a tangential chemical gradient. Solute molecules interact with the …
