Active colloids on fluid interfaces

J Deng, M Molaei, NG Chisholm, T Yao, A Read… - Current Opinion in …, 2022 - Elsevier
We review recent work on active colloids at interfaces, including self-propelled colloids that
move by generating a propulsive force, and driven colloids that move under external fields …

Active particles crossing sharp viscosity gradients

J Gong, VA Shaik, GJ Elfring - Scientific Reports, 2023 - nature.com
Active particles (living or synthetic) often move through inhomogeneous environments, such
as gradients in light, heat or nutrient concentration, that can lead to directed motion (or taxis) …

Dynamics of microswimmers near a liquid–liquid interface with viscosity difference

C Feng, JJ Molina, MS Turner, R Yamamoto - Physics of Fluids, 2023 - pubs.aip.org
Transport of material across liquid interfaces is ubiquitous for living cells and is also a crucial
step in drug delivery and in many industrial processes. The fluids that are present on either …

Two-dimensional long-range uniaxial order in three-dimensional active fluids

A Maitra - Nature Physics, 2023 - nature.com
Elongated active units cannot spontaneously break rotation symmetry in bulk fluids to form
nematic or polar phases. This has led to the image of active suspensions as spontaneously …

Dynamics of microswimmers near a soft penetrable interface

C Feng, JJ Molina, MS Turner, R Yamamoto - Physical Review Research, 2022 - APS
Few simulations exist for microswimmers near deformable interfaces. Here, we present
numerical simulations of the hydrodynamic flows associated with a single microswimmer …
