On the hydrodynamics of active particles in viscosity gradients
Vaseem A. Shaik, Gwynn J. Elfring
In this work, we analyze the motion of an active particle, modeled as a spherical squirmer, in linearly varying viscosity fields. In general, the presence of a particle will distur…

Towards an analytical description of active microswimmers in clean and in surfactant-covered drops
Alexander R. Sprenger, Vaseem A. Shaik, Arezoo M. Ardekani +6
Geometric confinements are frequently encountered in the biological world and strongly affect the stability, topology, and transport properties of active suspensions in viscous flo…

Wettability Modulated Charge Inversion and Ionic Transport in Nanofuidic Channels
Vaseem Akram Shaik, Aditya Bandopadhyay, Syed Sahil Hossain +1
We unveil the role of substrate wettability on the reversal in the sign of the interfacial charge distribution in a nanochannel in presence of multivalent ions. In sharp contrast t…
