We perform optical-tweezers experiments and mesoscale fluid simulations to study the
effective interactions between two parallel plates immersed in bacterial suspensions. The …

We analyze the dynamics of a passive colloidal probe immersed in an active bath using an
optical trap to study three physical processes:(1) the nonequilibrium fluctuations transferred …

The transport properties of colloidal particles in active liquids have been studied extensively.
It has led to a deeper understanding of the interactions between passive and active …

We extend the continuum theories of active nematohydrodynamics to model a two-fluid
mixture with separate velocity fields for each fluid component, coupled through a viscous …

The carbon fiber reinforced polyetheretherketone (CFR-PEEK) has been increasingly used
in orthopedics dentistry due to its excellent biocompatibility and mechanical properties …

Across a variety of spatial scales, from nanoscale biological systems to micron-scale
colloidal systems, equilibrium self-assembly is entirely dictated by—and therefore limited by …

Clustering passive particles by active agents is a promising route for fabrication of colloidal
structures. Here, we report the dynamic clustering of micrometric beads in a suspension of …

Dense bacterial suspensions display collective motion exhibiting coherent flow structures
reminiscent of turbulent flows. However, in contrast to inertial turbulence, the microscopic …

Reproducing bacteria self-organize to develop patterned biofilms in various conditions.
Various factors contribute to the shaping of a multicellular bacterial organization. Here we …

Communities of swimming microorganisms often thrive near liquid-air interfaces. We study
how suchactive carpets' shape their aquatic environment by driving biogenic transport in the …
