Life in a tight spot: Coupled dynamics of bacteria and soil across scales
Pablo Bravo, Tanumoy Dhar, Eloise Masquelier +2
Soil harbors much of Earth's bacterial life. The activity of these bacteria governs plant growth, carbon and nitrogen cycling, and the response of land to a changing climate. Under…
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…
Stability of co-annular active and passive confined fluids
Tanumoy Dhar, Michael J. Shelley, David Saintillan
The translation and shape deformations of a passive viscous Newtonian droplet immersed in an active nematic liquid crystal under circular confinement are analyzed using a linear st…
Active transport of a passive colloid in a bath of run-and-tumble particles
Tanumoy Dhar, David Saintillan
The dispersion of a passive colloid immersed in a bath of non-interacting and non-Brownian run-and-tumble microswimmers in two dimensions is analyzed using stochastic simulations a…
