Self-propulsion of chemically active droplets

S Michelin - Annual Review of Fluid Mechanics, 2023 - annualreviews.org
Microscopic active droplets are able to swim autonomously in viscous flows. This puzzling
feature stems from solute exchanges with the surrounding fluid via surface reactions or their …

Self-propelled swimming droplets

P Dwivedi, D Pillai, R Mangal - Current Opinion in Colloid & Interface …, 2022 - Elsevier
Self-propelled droplets are a class of active matter systems composed of one fluid dispersed
in another immiscible fluid. Despite the inherent spherical symmetry in the initial droplet …

We the droplets: a constitutional approach to active and self-propelled emulsions

S Birrer, SI Cheon, LD Zarzar - Current Opinion in Colloid & Interface …, 2022 - Elsevier
The field of active matter, and particularly active emulsions, is growing rapidly, with
significant progress made recently on both theoretical and experimental fronts. Here, we …

Chemotactic self-caging in active emulsions

BV Hokmabad, J Agudo-Canalejo… - Proceedings of the …, 2022 - National Acad Sciences
A common feature of biological self-organization is how active agents communicate with
each other or their environment via chemical signaling. Such communications, mediated by …

Design of nematic liquid crystals to control microscale dynamics

OD Lavrentovich - Liquid crystals reviews, 2020 - Taylor & Francis
Dynamics of small particles, both living and inanimate, has fascinated scientists for
centuries. Learning how to control it could open technological opportunities in the …

Active Brownian and inertial particles in disordered environments: Short-time expansion of the mean-square displacement

D Breoni, M Schmiedeberg, H Löwen - Physical Review E, 2020 - APS
We consider an active Brownian particle moving in a disordered two-dimensional energy or
motility landscape. The averaged mean-square displacement (MSD) of the particle is …

Activity-induced interactions and cooperation of artificial microswimmers in one-dimensional environments

S Ketzetzi, M Rinaldin, P Dröge, J Graaf… - Nature …, 2022 - nature.com
Cooperative motion in biological microswimmers is crucial for their survival as it facilitates
adhesion to surfaces, formation of hierarchical colonies, efficient motion, and enhanced …

Confined self-propulsion of an isotropic active colloid

F Picella, S Michelin - Journal of Fluid Mechanics, 2022 - cambridge.org
To spontaneously break their intrinsic symmetry and self-propel at the micron scale, isotropic
active colloidal particles and droplets exploit the nonlinear convective transport of chemical …

Alignment and scattering of colliding active droplets

K Lippera, M Benzaquen, S Michelin - Soft Matter, 2021 - pubs.rsc.org
Active droplets emit a chemical solute at their surface that modifies their local interfacial
tension. They exploit the nonlinear coupling of the convective transport of solute to the …

Interplay of chemotactic force, Péclet number, and dimensionality dictates the dynamics of auto-chemotactic chiral active droplets

CW Chan, Z Yang, Z Gan, R Zhang - The Journal of Chemical Physics, 2024 - pubs.aip.org
