Correlating microscopic viscoelasticity and structure of an aging colloidal gel using active microrheology and cryogenic scanning electron microscopy
Rajkumar Biswas, Vaibhav Raj Singh Parmar, Anson G Thambi +1
Optical tweezers (OTs) can detect pico-Newton range forces operating on a colloidal particle trapped in a medium and have been successfully utilized to investigate complex systems…
Growth kinetics of interfacial patterns formed by the radial displacement of an aging viscoelastic suspension
Palak, Vaibhav Raj Singh Parmar, Ranjini Bandyopadhyay
When a soft glassy colloidal suspension is displaced by a Newtonian fluid in a radial Hele-Shaw geometry, the pattern morphology that develops at the interface is determined by the…
Emergence of transient reverse fingers during radial displacement of a shear-thickening fluid
Palak Palak, Vaibhav Raj Singh Parmar, Sayantan Chanda +1
A highly sheared dense aqueous suspension of granular cornstarch particles displays rich nonlinear rheology. We had previously demonstrated the growth and onset of interfacial inst…
Pattern selection in radial displacements of a confined aging viscoelastic fluid
Palak Palak, Vaibhav Raj Singh Parmar, Debasish Saha +1
Intricate fluid displacement patterns, arising from the unstable growth of interfacial perturbations, can be driven by fluid viscoelasticity and surface tension. A soft glassy susp…
