We study the nonequilibrium interaction of two isotropic chemically active particles taking
into account the exact near-field chemical interactions as well as hydrodynamic interactions. …

We derive a theorem for the lower bound on the energy dissipation rate by a rigid surface-driven
active microswimmer of arbitrary shape in a fluid at a low Reynolds number. We show …

We examine swimmers comprising of two rigid spheres which oscillate periodically along their
axis of symmetry, considering when the spheres oscillate both in phase and in antiphase, …

Microorganisms develop coordinated beating patterns on surfaces lined with cilia known as
metachronal waves. For a chain of cilia attached to a flat ciliate, it has been shown that …

Living cells harvest energy from their environments to drive the chemical processes that
enable life. We introduce a minimal system that operates at similar protein concentrations, …

We consider a swimmer consisting of a collinear assembly of three spheres connected by two
slender rods. This swimmer can propel itself forward by varying the lengths of the rods in a …

The ability of microswimmers to deploy optimal propulsion strategies is of paramount importance
for their locomotory performance and survival at low Reynolds numbers. Although for …

We study the axisymmetric interaction of two chemically active Janus particles. By relying on
the linearity of the field equations and symmetry arguments, we derive a generic solution for …

Confined gas–liquid droplet microflows present a lot of new perspectives for microfluidic
systems that require the presence of a gaseous phase. In addition to the benefits associated …

Swimming at low Reynolds number in Newtonian fluids is only possible through nonreciprocal
body deformations due to the kinematic reversibility of the Stokes equations. We consider …
