Tunable capillary-induced attraction between vertical cylinders
Jennifer M. Rieser, P. E. Arratia, A. G. Yodh +2
Deformation of a fluid interface caused by the presence of objects at the interface can lead to large lateral forces between the objects. We explore these fluid-mediated attractive…
Role of disorder in finite-amplitude shear of a 2D jammed material
Nathan C. Keim, Paulo E. Arratia
A material's response to small but finite deformations can reveal the roots of its response to much larger deformations. Here, we identify commonalities in the responses of 2D soft…
Undulatory swimming in shear-thinning fluids: Experiments with C. elegans
David A. Gagnon, Nathan C. Keim, Paulo E. Arratia
The swimming behaviour of microorganisms can be strongly influenced by the rheology of their fluid environment. In this manuscript, we experimentally investigate the effects of she…
Fluid-Induced Propulsion of Rigid Particles in Wormlike Micellar Solutions
David A. Gagnon, Nathan C. Keim, Xiaoning Shen +1
In the absence of inertia, a reciprocal swimmer achieves no net motion in a viscous Newtonian fluid. Here, we investigate the ability of a reciprocally actuated particle to transla…
