Contamination dynamics of active rods in long microchannels
Jason Palos, Chase Brown, Mykhailo Potomkin +1
Active rods are elongated, self-propelled particles that serve as effective models for motile microorganisms, such as bacteria and sperm cells. When confined to a microfluidic chan…
Active matter within flexible boundaries: a novel experimental approach with T. aceti nematodes
Christina M. Ceballos, Matthew S. Mizuhara, Mykhailo Potomkin +1
We experimentally explore the collective behavior of the nematode T. Aceti inside flexible boundaries showing the emergence of previously unreported states. These nematodes have be…
Kinetics of an Expanding Bacterial Colony: Continuum Modeling and Analysis
Bo Li, Mykhailo Potomkin
We study the spatiotemporal dynamics of the expansion of a bacterial colony on a hard substrate. Nutrient from the substrate diffuses into the colony and is taken up by the bacteri…
Multiscale Analysis of a Kinetic Model of Confined Suspensions of Self-Propelled Rods
Leonid Berlyand, Spencer Dang, Pierre-Emmanuel Jabin +1
The behavior of active matter under confinement poses significant challenges due to the intricate coupling between dynamics near boundaries and those in the bulk. A defining featur…
Boundary accumulations of active rods in microchannels with elliptical cross-section
Chase Brown, Mykhailo Potomkin, Shawn Ryan
Many motile microorganisms and bio-mimetic micro-particles have been successfully modeled as active rods - elongated bodies capable of self-propulsion. A hallmark of active rod dyn…
Dynamics and steady state of squirmer motion in liquid crystal
Leonid Berlyand, Hai Chi, Mykhailo Potomkin +1
We analyze a nonlinear PDE system describing the motion of a microswimmer in a nematic liquid crystal environment. For the microswimmer's motility, the squirmer model is used in wh…
