Inferring Surface Slip in Active Colloids from Flow Fields Using Physics-Informed Neural Networks
Parvin Bayati, Stewart A. Mallory
The directed motion of active colloids is governed by spatial variations in surface chemistry and interfacial stress, yet these properties remain extremely difficult to measure dir…

Sedimentation equilibrium as a probe of the pressure equation of state of active colloids
Yunhee Choi, Elijah Schiltz-Rouse, Parvin Bayati +1
We introduce a theoretical and computational framework for extracting the pressure equation of state (EoS) of an active suspension from its steady-state sedimentation profile. As E…

Single-File Diffusion of Active Brownian Particles
A. Akintunde, P. Bayati, H. Row +1
Single-file diffusion (SFD) is a key mechanism underlying transport phenomena in confined physical and biological systems. In a typical SFD process, microscopic particles are restr…
