From Disks to Channels: Dynamics of Active Nematics Confined to an Annulus
Chaitanya Joshi, Zahra Zarei, Michael M. Norton +3
Confinement can be used to systematically tame turbulent dynamics occurring in active fluids. Although periodic channels are the simplest geometries to study confinement numericall…
Light-activated microtubule-based 2D active nematic
Zahra Zarei, John Berezney, Alexander Hensley +4
We characterize two-dimensional (2D) microtubule-based active nematics driven by light-responsive kinesin motor clusters. We assess two constructs of optogenetic kinesin: opto-K401…
Geometrically programmed self-limited assembly of tubules using DNA origami colloids
Daichi Hayakawa, Thomas E. Videbæk, Douglas M. Hall +8
Self-assembly is one of the most promising strategies for making functional materials at the nanoscale, yet new design principles for making self-limiting architectures, rather tha…
Active pulsatile gels: from chemical microreactor to polymeric actuator
Baptiste Blanc, Zhenkun Zhang, Eric Liu +5
We report on a synthesis protocol, experimental characterization and theoretical modeling of active pulsatile Belousov-Zhabotinsky (BZ) hydrogels. Our two-step synthesis technique…
Extensile to contractile transition in active microtubule-actin composites generates layered asters with programmable lifetimes
John Berezney, Bruce L. Goode, Seth Fraden +1
We study a reconstituted composite system consisting of an active microtubule network interdigitated with a passive network of entangled F-actin filaments. Increasing viscoelastici…
Effects of confinement on the dynamics and correlation scales in active fluids
Yi Fan, Kun-Ta Wu, Ali Aghvami +2
We study the influence of solid boundaries on dynamics and structure of active fluids as the height of the container, , changes. Along the varying dimension, the geometry system…
