Tuning the rheology and microstructure of particle-laden fluid interfaces with Janus particles
Yiming Qiao, Xiaolei Ma, Zhengyang Liu +3
Hypothesis: Particle-laden fluid interfaces are the central component of many natural and engineering systems. Understanding the mechanical properties and improving the stability o…
Crack patterns of drying dense bacterial suspensions
Xiaolei Ma, Zhengyang Liu, Wei Zeng +3
Drying of bacterial suspensions is frequently encountered in a plethora of natural and engineering processes. However, the evaporation-driven mechanical instabilities of dense cons…
Density Fluctuations and Energy Spectra of 3D Bacterial Suspensions
Zhengyang Liu, Wei Zeng, Xiaolei Ma +1
We experimentally study density fluctuations and energy spectra of bulk \textit{E. coli} suspensions of different concentrations. Our results verify the predicted scaling law of gi…
Imaging the emergence of bacterial turbulence: phase diagram and transition kinetics
Yi Peng, Zhengyang Liu, Xiang Cheng
We experimentally study the emergence of collective bacterial swimming, a phenomenon often referred to as bacterial turbulence. A phase diagram of the flow of 3D E. coli suspension…
Rheology of bacterial suspensions under confinement
Zhengyang Liu, Kechun Zhang, Xiang Cheng
As a paradigmatic model of active fluids, bacterial suspensions show intriguing rheological responses drastically different from their counterpart colloidal suspensions. Although t…
Dynamics of ellipsoidal tracers in swimming algal suspensions
Ou Yang, Yi Peng, Zhengyang Liu +3
Enhanced diffusion of passive tracers immersed in active fluids is a universal feature of active fluids and has been extensively studied in recent years. Similar to microrheology f…
