Self-organization of active colloids mediated by chemical interactions
Zhiwei Peng, Raymond Kapral
Self-propelled colloidal particles exhibit rich non-equilibrium phenomena and have promising applications in fields such as drug delivery and self-assembled active materials. Previ…
Confined active matter in external fields
Vaseem A. Shaik, Zhiwei Peng, John F. Brady +1
We analyze a dilute suspension of active particles confined between walls and subjected to fields that can modulate particle speed as well as orientation. Generally, the particle d…
Trapped-particle microrheology of active suspensions
Zhiwei Peng, John F. Brady
In microrheology, the local rheological properties such as viscoelasticity of a complex fluid are inferred from the free or forced motion of embedded colloidal probe particles. The…
Activity-induced propulsion of a vesicle
Zhiwei Peng, Tingtao Zhou, John F. Brady
Modern biomedical applications such as targeted drug delivery require a delivery system capable of enhanced transport beyond that of passive Brownian diffusion. In this work an osm…
Maximizing propulsive thrust of a driven filament at low Reynolds number via variable flexibility
Zhiwei Peng, Gwynn J. Elfring, On Shun Pak
At low Reynolds numbers the locomotive capability of a body can be dramatically hindered by the absence of inertia. In this work, we show how propulsive performance in this regime…
