Colloid recovery from porous structures under ambient flow: enhanced extraction via phoretic and osmotic mechanisms
Jitendra Dhakar, Kapil Upadhyaya, Akash Choudhary
Chemical gradients are widely employed to enhance particle transport in porous media, such as laundry detergency and enhanced oil recovery. Diffusiophoresis and diffusioosmosis ref…
Propulsion and far-field hydrodynamics of linked-sphere microswimmers with viscoelastic deformability
Vimal Singh, Akash Choudhary
Viscoelasticity governs the locomotion strategies of deformable microorganisms, rendering it a fundamental mechanical property of microbial motility and an integral component in th…
Tuning Cross-stream Lift in Viscoelastic Shear: Distinct Hydrodynamic Signatures of Force-bearing and Force-free Mechanisms
Soumyodeep Chowdhury, Kushagra Tiwari, Jitendra Dhakar +1
We investigate the lift and drag corrections acting on a particle suspended in a planar viscoelastic shear flow when the particle is tuned to translate relative to the flow by an e…
Clustering Dynamics of SiO2-Pt Active Janus Colloids
Harishwar Raman, Aniket Shivhare, Amit Kumar +5
Active colloid clustering is central to understanding non-equilibrium self-organization, with implications for programmable active materials and synthetic or biological assemblies.…
