Synchro-nematic and -antinematic ordering of spheroidal circle swimmers

Anson G. Thambi, Alexander N. Dodge, William E. Uspal

Chirality gives a microswimmer something a straight-line swimmer lacks: a phase. This variable both modulates, and is affected by, the hydrodynamic interactions between microswimme…

Clustering and emergent hyperuniformity by breaking microswimmer shape and actuation symmetries

Anson G. Thambi, William E. Uspal

Hydrodynamic interactions driven by particle activity are ubiquitous in active colloidal systems. Although these interactions are strongly influenced by the interfacial actuation m…

Hydrodynamic Stokes flow induced by a chemically active patch imprinted on a planar wall

Mihail N. Popescu, Bogdan Adrian Nicola, William E. Uspal +2

Patches of catalyst imprinted on supporting walls induce motion of the fluid around them once they are supplied with the chemical species (``fuel'') that are converted by the catal…

Chemotactic behavior for a self-phoretic Janus particle near a patch source of fuel

Viviana Mancuso, Mihail N. Popescu, William E. Uspal

Many biological microswimmers are capable of chemotaxis, i.e., they can sense an ambient chemical gradient and adjust their mechanism of motility to move towards or away from the s…

Shape-induced pairing of spheroidal squirmers

Ruben Poehnl, William E. Uspal

The "squirmer model" is a classical hydrodynamic model for the motion of interfacially-driven microswimmers, such as self-phoretic colloids or volvocine green algae. To date, most…

Universal motion of mirror-symmetric microparticles in confined Stokes flow

Rumen N. Georgiev, Sara O. Toscano, William E. Uspal +4

Comprehensive understanding of particle motion in microfluidic devices is essential to unlock novel technologies for shape-based separation and sorting of microparticles like micro…
