Biophysical fluid dynamics in a Petri dish

GT Fortune, E Lauga, RE Goldstein - Physical Review Fluids, 2024 - APS
The humble Petri dish is perhaps the simplest setting in which to examine the locomotion of
swimming organisms, particularly those whose body size is tens of microns to millimeters …

Interfacial activity dynamics of confined active droplets

P Ramesh, BV Hokmabad, DO Pushkin… - Journal of Fluid …, 2023 - cambridge.org
Active emulsions can spontaneously form self-propelled droplets or phoretic micropumps.
However, it remains unclear how these active systems interact with their self-generated …
