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…
Viscosity Metamaterials
Prateek Sehgal, Meera Ramaswamy, Edward Y. X. Ong +3
Metamaterials are composite structures whose properties arise from a mesoscale organization of their constituents. Provided this organization occurs on scales smaller than the char…
Incorporating tunability into a universal scaling framework for shear thickening
Meera Ramaswamy, Itay Griniasty, James P Sethna +2
Recently, we proposed a universal scaling framework that shows shear thickening in dense suspensions is governed by the crossover between two critical points: one associated with f…
Universal scaling of shear thickening transitions
Meera Ramaswamy, Itay Griniasty, Danilo B. Liarte +6
Nearly all dense suspensions undergo dramatic and abrupt thickening transitions in their flow behaviour when sheared at high stresses. Such transitions occur when the dominant inte…
Embedding Orthogonal Memories in a Colloidal Gel through Oscillatory Shear
Eric M Schwen, Meera Ramaswamy, Chieh-Min Cheng +2
It has recently been shown that in a broad class of disordered systems oscillatory shear training can embed memories of specific shear protocols in relevant physical parameters suc…
Using Acoustic Perturbations to Dynamically Tune Shear Thickening in Colloidal Suspensions
Prateek Sehgal, Meera Ramaswamy, Itai Cohen +1
Colloidal suspensions in industrial processes often exhibit shear thickening that is difficult to control actively. Here, we use piezoelectric transducers to apply acoustic perturb…
How Confinement-Induced Structures Alter the Contribution of Hydrodynamic and Short-Ranged Repulsion Forces to the Viscosity of Colloidal Suspensions
Meera Ramaswamy, Neil Y. C. Lin, Brian D. Leahy +4
Understanding the correlation between structure and rheology in colloidal suspensions is important as these suspensions are crucial in industrial applications. Moreover, colloids e…
