Stiffness-dependent Dielectric Relaxation in Thermoreversible Microgels: Effects of Temperature and Strain
Sayantan Chanda, Sonali Vasant Kawale, Ranjini Bandyopadhyay
We investigate how particle stiffness governs length-scale-dependent relaxation dynamics in dense suspensions of thermoresponsive PNIPAM microgels subjected to temperature variatio…
Bubble-Driven Flow Transitions in Evaporating Active Droplets on Structured Surfaces
Meneka Banik, Ranjini Bandyopadhyay
The evaporation of particle-laden droplets on engineered surfaces underpins a wide range of technologies, from printed electronics to biosensing. While the influence of substrate t…
Permeability heterogeneity and bulk linear elasticity of displaced clay suspensions determine interfacial pattern morphologies in Hele-Shaw experiments
Vaibhav Raj Singh Parmar, Ranjini Bandyopadhyay
When a less viscous Newtonian fluid displaces an aging aqueous clay suspension in a confined space, a rich array of interfacial patterns emerges due to a predominantly viscous inst…
Thermal History Asymmetry and Dissipation in Dense Colloidal Microgel Glasses
Sonali Vasant Kawale, Yogesh M Joshi, Ranjini Bandyopadhyay
Microstructurally arrested matter, from molecular glasses to soft glassy materials, can retain a memory of their thermal or mechanical (shear) histories. Their history-dependent an…
Investigating the roles of hydrophobicity and electrostatics in the particle-scale dynamics and rheology of dense microgel suspensions
Sayantan Chanda, Chandeshwar Misra, Ranjini Bandyopadhyay
Colloidal microgel particles such as poly(N-isopropylacrylamide) (PNIPAM) shrink reversibly in an aqueous medium due to the expulsion of water at a volume phase transition temperat…
Using optical tweezer electrophoresis to investigate clay nanoplatelet adsorption on Latex microspheres in aqueous media
Vaibhav Raj Singh Parmar, Sayantan Chanda, Sri Vishnu Bharat Sivasubramaniam +1
The adsorption of charged clay nanoplatelets plays an important role in stabilizing emulsions by forming a barrier around the emulsion droplets and preventing coalescence. In this…
