The effects of ionic valency and size asymmetry on counterion adsorption
Or Ben Yaakov, Haim Diamant, Rudolf Podgornik +1
We study the effect of asymmetry in solvent and ionic size on the equilibrium properties of multivalent ionic solutions near a charged surface. For a single ionic species in soluti…
Collapse of a single polymer chain: Effects of chain stiffness and attraction range
Yanyan Zhu, Haim Diamant, David Andelman
Chain-like macromolecules in solution, whether biological or synthetic, transform from an extended conformation to a compact one when temperature or other system parameters change.…
Learning general pair interactions between self-propelled particles
Jérôme Hem, Alexis Poncet, Pierre Ronceray +2
Synthetic active matter systems, such as active colloids, often have complex interactions, which can be of hydrodynamic, chemical or electrostatic origin and cannot be computed fro…
Shape transitions of sedimenting confined droplets and capsules: from oblate to bullet-like geometries
Danilo P. F. Silva, Rodrigo C. V. Coelho, Ariel Dvir +4
The transport and deformation of confined droplets and flexible capsules are central to diverse phenomena and applications, from biological flows in microcapillaries to industrial…
Diffusive dynamics of charge regulated macro-ion solutions
Bin Zheng, Shigeyuki Komura, David Andelman +1
Onsager's variational principle is generalized to address the diffusive dynamics of an electrolyte solution composed of charge-regulated macro-ions and counterions. The free energy…
A geometric condition for robot-swarm cohesion and cluster-flock transition
Mathias Casiulis, Eden Arbel, Charlotte van Waes +4
We present a geometric design rule for size-controlled clustering of self-propelled particles. We show that active particles that tend to rotate under an external force have an int…
Generic elasticity of thermal, under-constrained systems
Cheng-Tai Lee, Matthias Merkel
Athermal (i.e. zero-temperature) under-constrained systems are typically floppy, but they can be rigidified by the application of external strain, which is theoretically well under…
Partition sum of thermal, under-constrained systems
Cheng-Tai Lee, Matthias Merkel
Athermal (i.e. zero-temperature) under-constrained systems are typically floppy, but they can be rigidified by the application of external strain. Following our recently developed…
A wrinkled cylindrical shell as a tunable locking material
Pan Dong, Mengfei He, Nathan C. Keim +1
A buckled sheet offers a reservoir of material that can be unfurled at a later time. For sufficiently thin yet stiff materials, this geometric process has a striking mechanical fea…
Interplay of gross and fine structures in strongly-curved sheets
Mengfei He, Vincent Démery, Joseph D. Paulsen
Although thin films are typically manufactured in planar sheets or rolls, they are often forced into three-dimensional shapes, producing a plethora of structures across multiple le…
Soft Metamaterials: Adaptation and Intelligence
Colin Scheibner, Michel Fruchart, Vincenzo Vitelli
We provide a perspective on soft metamaterials and biomatter with a special emphasis on future research directions at the interface between material intelligence and adaptation.
Propagating irreversibility fronts in cyclically-sheared suspensions
Jikai Wang, J. M. Schwarz, Joseph D. Paulsen
The interface separating a liquid from its vapor phase is diffuse: the composition varies continuously from one phase to the other over a finite length. Recent experiments on dynam…
Sculpting liquids with ultrathin shells
Yousra Timounay, Alexander R. Hartwell, Mengfei He +4
Thin elastic films can spontaneously attach to liquid interfaces, offering a platform for tailoring their physical, chemical, and optical properties. Current understanding of the e…
Shear dynamics of confined membranes
Thomas Le Goff, Tung B. T. To, Olivier Pierre-Louis
We model the nonlinear response of a lubricated contact composed of a two-dimensional lipid membrane immersed in a simple fluid between two parallel flat and porous walls under she…
Understanding and controlling hexagonal patterns of wrinkles in neo-Hookean elastic bilayer structures
Teng Zhang
A controlled surface wrinkling pattern has been widely used in diverse applications, such as stretchable electronics, smart windows, and haptics. Here, we focus on hexagonal wrinkl…
Geometric signatures of tissue surface tension in a three-dimensional model of confluent tissue
Preeti Sahu, J. M. Schwarz, M. Lisa Manning
In dense biological tissues, cell types performing different roles remain segregated by maintaining sharp interfaces. To better understand the mechanisms for such sharp compartment…
Multiperiodic orbits from interacting soft spots in cyclically-sheared amorphous solids
Nathan C. Keim, Joseph D. Paulsen
When an amorphous solid is deformed cyclically, it may reach a steady state in which the paths of constituent particles trace out closed loops that repeat in each driving cycle. A…
Soft topological modes protected by symmetry in rigid mechanical metamaterials
Hridesh Kedia, Anton Souslov, D. Zeb Rocklin
Topological mechanics can realize soft modes in mechanical metamaterials in which the number of degrees of freedom for particle motion is finely balanced by the constraints provide…
Mesoscale structure of wrinkle patterns and defect-proliferated liquid crystalline phases
Oleh Tovkach, Junbo Chen, Monica M. Ripp +3
Thin solids often develop elastic instabilities and subsequently complex, multiscale deformation patterns. Revealing the organizing principles of this spatial complexity has ramifi…
Natural selection in the colloid world: Active chiral spirals
Jie Zhang, Steve Granick
We present a model system in which to study natural selection in the colloid world. In the assembly of active Janus particles into rotating pinwheels when mixed with trace amounts…
