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…

Direct experimental measurement of many-body hydrodynamic interactions with optical tweezers
Dae Yeon Kim, Sachit G. Nagella, Kyu Hwan Choi +1
Many-body hydrodynamic interactions (HIs) play an important role in the dynamics of fluid suspensions. While many-body HIs have been studied extensively using particle simulations,…

Motility Modulates the Partitioning of Bacteria in Aqueous Two-Phase Systems
Jiyong Cheon, Kyu Hwan Choi, Kevin J. Modica +3
We study the partitioning of motile bacteria in an aqueous two-phase mixture of dextran (DEX) and polyethylene glycol (PEG), which can phase separate into DEX-rich and PEG-rich pha…
