Biogenic bubbles enable microbial escape from physical confinement
Babak Vajdi Hokmabad, Thomas Appleford, Hao Nghi Luu +3
Immotile microbes inhabit nearly every environment on Earth, from soils and sediments to food matrices -- yet how they disperse through these physically confining environments is p…
Universal scaling of shear thickening suspensions under acoustic perturbation
Anna R. Barth, Navneet Singh, Stephen J. Thornton +7
Tuning shear thickening behavior is a longstanding problem in the field of dense suspensions. Acoustic perturbations offer a convenient way to control shear thickening in real time…
Getting out of a tight spot: Cooperative unclogging of hydrogel particles in disordered porous media
Sanjana Kamath, Laurent Talon, Meera Ramaswamy +2
We use event-driven pore network modeling to study the transport of hydrogel particles through disordered porous media -- a process that underlies diverse applications. By simulati…
Jamming memory into acoustically trained dense suspensions under shear
Edward Y. X. Ong, Anna R. Barth, Navneet Singh +5
Systems driven far from equilibrium often retain structural memories of their processing history. This memory has, in some cases, been shown to dramatically alter the material resp…
