Mechanical instability generates monodisperse colloidosomes
Seungwoo Shin, Federico Cao, Robert A. Pelcovits +2
Formation and rupture of vesicles is a fundamental process underlying diverse phenomena in biology, materials science, and biomedical applications. Vesicles form when the area of a…
Confinement geometry governs the impact of external shear stress on active stress-driven flows in microtubule-kinesin active fluids
Joshua H. Dickie, Tianxing Weng, Yen-Chen Chen +5
Active fluids generate internal active stress and exhibit unique responses to external forces such as superfluidity and self-yielding transitions. However, how confinement geometry…
Interfacial instability of confined 3D active droplets
Bennett C. Sessa, Federico Cao, Robert A. Pelcovits +2
Instabilities of fluid-fluid interfaces are ubiquitous in passive soft matter. Adding activity to the interface or either fluid can dramatically change the stability of the interfa…
Brownian Dynamics Simulations of Inclusions in an Active Fluid Bath
Lijie Ding, Robert A. Pelcovits, Thomas R. Powers
We carry out two-dimensional Brownian dynamics simulations of the behavior of rigid inclusion particles immersed in an active fluid bath. The active fluid is modeled as a collectio…
Topology and Kinetic Pathways of Colloidosome Assembly and Disassembly
Raymond Adkins, Joanna Robaszewski, Seungwoo Shin +7
Liquid shells, such as lipid vesicles and soap bubbles, are ubiquitous throughout biology, engineered matter, and everyday life. Their creation and disintegration are defined by a…
