Confinement-Connectivity Coupling Enables High-Efficiency Piezoionic Transduction
Tofayel Ahammad Ovee, Daniel Kroeger, Jean-François Louf
Piezoionic hydrogels offer a route to mechanically driven bioelectronic interfaces, but their output is limited by rapid, symmetric ion redistribution that dissipates charge gradie…
Universal Scaling of Freezing Morphodynamics in Polymer Solution Droplets
Nicolas G. Ulrich, Pravin P. Aravindhan, Olivia Berger +2
Freezing of complex fluids is central to a wide range of natural and technological processes, where the interplay between heat transport, solute redistribution, and interfacial def…
Obstructed swelling and fracture of hydrogels
Abigail Plummer, Caroline Adkins, Jean-François Louf +2
Obstructions influence the growth and expansion of bodies in a wide range of settings -- but isolating and understanding their impact can be difficult in complex environments. Here…
Effect of confinement on the mechanics of a swelling hydrogel bead
Chaitanya Joshi, Mathew Q. Giso, Jean-François Louf +2
We recast the problem of hydrogel swelling under physical constraints as an energy optimization problem. We apply this approach to compute equilibrium shapes of hydrogel spheres co…
Microbial narrow-escape is facilitated by wall interactions
Mathieu Souzy, Antoine Allard, Jean-François Louf +3
Cells have evolved efficient strategies to probe their surroundings and navigate through complex environments. From metastatic spread in the body to swimming cells in porous materi…
Under pressure: Hydrogel swelling in a granular medium
Jean-François Louf, Nancy B. Lu, Margaret G. O'Connell +2
Hydrogels hold promise in agriculture as reservoirs of water in dry soil, potentially alleviating the burden of irrigation. However, confinement in soil can markedly reduce the abi…
Elastocapillary network model of inhalation
Jean-François Louf, Felix Kratz, Sujit S. Datta
The seemingly simple process of inhalation relies on a complex interplay between muscular contraction in the thorax, elasto-capillary interactions in individual lung branches, prop…
Imbibition in plant seeds
Jean-François Louf, Yi Zheng, Aradhana Kumar +5
We describe imbibition in real and artificial plant seeds, using a combination of experiments and theory. In both systems, our experiments demonstrate that liquid permeates the sub…
