Phase-separation during sedimentation of dilute bacterial suspensions
Bryan O. Torres Maldonado, Ranjiangshang Ran, K. Lawrence Galloway +3
Numerous natural systems depend on the sedimentation of passive particles in presence of swimming microorganisms. Here, we investigate the dynamics of the sedimentation of spherica…
Metallic Microswimmers Driven up the Wall by Gravity
Quentin Brosseau, Florencio Balboa Usabiaga, Enkeleida Lushi +5
As a natural and functional behavior, various microorganisms exhibit gravitaxis by orienting and swimming upwards against gravity. Swimming autophoretic nanomotors described herein…
Relating microswimmer synthesis to rheotactic tunability
Quentin Brosseau, Florencio Balboa Usabiaga, Enkeleida Lushi +5
We explore the behavior of micron-scale autophoretic Janus (Au/Pt) rods, having various Au/Pt length ratios, swimming near a wall in an imposed background flow. We find that their…
Fluid rings and droplet arrays via rim streaming
Quentin Brosseau, Petia M. Vlahovska
Tip-streaming generates micron- and submicron- sized droplets when a thin thread pulled from the pointy end of a drop disintegrates. Here, we report streaming from the equator of a…
Electrohydrodynamic Quincke rotation of a prolate ellipsoid
Quentin Brosseau, Gregory Hickey, Petia M. Vlahovska
We experimentally study the occurrence of spontaneous spinning (Quincke rotation) of an ellipsoid in a uniform DC electric field. For an ellipsoid suspended in an unbounded fluid,…
