Programming Boundary Deformation Patterns in Active Networks
Zijie Qu, Jialong Jiang, Heun Jin Lee +3
Active materials take advantage of their internal sources of energy to self-organize in an automated manner. This feature provides a novel opportunity to design micron-scale machin…
Persistent fluid flows defined by active matter boundaries
Zijie Qu, Dominik Schildknecht, Shahriar Shadkhoo +5
Biological systems achieve precise control over ambient fluids through the self-organization of active protein structures including flagella, cilia, and cytoskeletal networks. In a…
Measuring the viscoelastic behavior of dilute polymer solutions using high-speed statistical particle microrheology
Zijie Qu, Xiongfeng Yi, Kenneth S. Breuer
The viscoelastic behavior of polymer solutions is commonly measured using oscillating shear rheometry, however, the accuracy of such methods is limited by the oscillating frequency…
Effects of shear thinning viscosity and viscoelastic stresses on flagellated bacteria motility
Zijie Qu, Kenneth S. Breuer
The behavior of flagellated bacteria swimming in non-Newtonian media remains an area with contradictory and conflicting results. We report on the behavior of wild-type and smooth-s…
Controlling Organization and Forces in Active Matter Through Optically-Defined Boundaries
Tyler D. Ross, Heun Jin Lee, Zijie Qu +3
Living systems are capable of locomotion, reconfiguration, and replication. To perform these tasks, cells spatiotemporally coordinate the interactions of force-generating, "active"…
Changes in the flagellar bundling time account for variations in swimming behavior of flagellated bacteria in viscous media
Zijie Qu, Fatma Zeynep Temel, Rene Henderikx +1
Although the motility of the flagellated bacteria, Escherichia coli, has been widely studied, the effect of viscosity on swimming speed remains controversial. The swimming mode of…
