Mechanics of heterogeneous fiber networks
Kyu Hwan Choi, Sattvic Ray, Reef Sweeney +2
Internally generated active stresses drive soft materials into architectures inaccessible to thermal self-assembly. We use a microtubule-based active fluid to assemble and irrevers…
Bicontinuity in active phase separation
Paarth Gulati, Liang Zhao, Michio Tateno +3
We study phase separation between coexisting active and passive fluids in three-dimensions, using numerical simulation and experiments. Chaotic flows of the active phase drive gian…
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…
Active assembly and non-reciprocal dynamics of elastic membranes
John Berezney, Sattvic Ray, Itamar Kolvin +6
Equilibrium self-assembly and conventional materials processing techniques fall far short of mimicking dynamic self-actuating processes that are commonplace throughout biology. To…
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…
Closed-loop control of active nematic flows
Katsu Nishiyama, John Berezney, Michael M. Norton +5
Living things enact control of non-equilibrium, dynamical structures through complex biochemical networks, accomplishing spatiotemporally-orchestrated physiological tasks such as c…
