Morphodynamics of lipid vesicles under osmotic forcing
Nicholas Broussinos, David Saintillan
We investigate the dynamics of spherical lipid vesicles subjected to an osmotic shock using continuum simulations of a permeable, area-incompressible fluid membrane with bending el…
Geodesic Trapping and Escape of Active Particles on Curved Surfaces
Yuzhu Chen, Vishal P. Patil, David Saintillan
Active particles on curved surfaces can become trapped along closed geodesics even without physical barriers. We show that escape from these geometric traps exposes a fundamental d…
Pore-scale distribution and transport of active particles in a two-dimensional lattice
Akhil Varma, David Saintillan
Suspensions of motile microswimmers such as bacteria and other active colloids frequently encounter porous environments where obstacles and complex shear flows strongly influence t…
Collective dynamics of active suspensions on curved viscous interfaces
Yuzhu Chen, Vishal P. Patil, David Saintillan
Self-propelled particles can navigate complex environments, including viscous fluid interfaces with curved geometries. In this work, we study the emergent dynamics of a suspension…
Reversibility, Chaos, and Attractors in Periodically Sheared Elastic Filaments
Francesco Bonacci, Brato Chakrabarti, Olivia du Roure +2
The dynamics of filaments in flow are central to understanding a wide range of biological and soft-matter systems, yet their behavior under time-dependent forcing remains poorly un…
Hydrodynamics converts chiral flagellar rotation into contactless actuation of microdiscs
Daniel Grober, Tanumoy Dhar, David Saintillan +1
Motile bacteria are a wonder of nature's engineering: microscopic engines that transduce biochemical energy into the work they require to explore their environment. This added ener…
