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…
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.…
On the influence of electrolytic gradient orientation on phoretic transport in dead-end pores
Kushagra Tiwari, Jitendra Dhakar, Kapil Upadhyaya +1
Electrolytic diffusiophoresis refers to directional migration of colloids due to interfacial forces that develop in response to local electrolytic concentration () gradients. Th…
A bi-directional low-Reynolds-number swimmer with passive elastic arms
Jessie Levillain, François Alouges, Antonio Desimone +3
It has been recently shown that it is possible to design simple artificial swimmers at low Reynoldsnumber that possess only one degree of freedom and, nevertheless, can overcome Pu…
Pair-Interactions of Self-Propelled SiO2-Pt Janus Colloids: Chemically Mediated Interactions
Karnika Singh, Harishwar Raman, Shwetabh Tripathi +3
Driven by the necessity to achieve a thorough comprehension of the bottom-up fabrication process of functional materials, this experimental study investigates the pair-wise interac…
