Deformation-induced spectral softening drives phase separation on non-spherical membranes
Avraham Moriel, Howard A. Stone
Models of curvature-driven membrane sorting couple composition directly to membrane bending elasticity. Here we show that shape deformations can destabilize a homogeneous state wit…
Nonlinear diffusion and compressive rims in source-driven biopolymer condensates
Avraham Moriel, Howard A. Stone
Many subcellular condensates continuously produce biopolymers. Coupling Flory-Huggins thermodynamics to two-fluid viscoelasticity, we probe the diffusion of such source-driven poly…
Polymer-polymer interdiffusion: effects of entanglements and a polymeric source
Avraham Moriel, Howard A. Stone
Many industrial applications and biological scenarios involve the interdiffusion of two polymeric species. Motivated by biological subcellular source-driven processes, we study pol…
Enucleated incompressible red blood cells in shear flow: theoretical analysis of shape instabilities
Avraham Moriel, Howard A. Stone, Simon Mendez
Red blood cells (RBCs) are essential for oxygen transport, and their remarkable ability to undergo significant deformations during flow is a crucial feature for their physiological…
Design of model Boger fluids with systematically controlled viscoelastic properties
Jonghyun Hwang, Howard A. Stone
The subject of viscoelastic flow phenomena is crucial to many areas of engineering and the physical sciences. Although much of our understanding of viscoelastic flow features stems…
Revealing Actual Viscoelastic Relaxation Times in Capillary Breakup
Nan Hu, Jonghyun Hwang, Tachin Ruangkriengsin +1
We use experiments and theory to elucidate the size effect in capillary breakup rheometry, where pre-stretching in the visco-capillary stage causes the apparent relaxation time to…
Close-contact melting on hydrophobic textured surfaces: Confinement and meniscus effects
Nan Hu, Liwu Fan, Xiang Gao +1
We investigate the dynamics of close-contact melting (CCM) on gas-trapped hydrophobic surfaces, with specific focus on the effects of geometrical confinement and the liquid-air men…
Surface Furrowing Instability in Everting Soft Solids
Jonghyun Hwang, Mariana Altomare, Howard A. Stone
We report a surface instability observed during the extrusion of extremely soft elastic solids in confined geometries. Due to their unique rheological properties, these soft solids…
