Kinetic effects on the phase behavior and microstructural transitions of a thermoresponsive polymer solution
Pritha Acharya, Riya Karmakar, Khushboo Suman
The thermoresponsive behavior of Pluronic F127 solutions is governed by temperature-dependent micellization and complex self-assembly of these micelles. This study investigates the…
Mastering Rheology: A Strategic and practical guide for empowering all users
Khushboo Suman
Rheology, the study of flow, plays a vital role in diverse industries such as pharmaceuticals, cosmetics and food. In this work, we provide a comprehensive introduction to fundamen…
Aqueous Laponite Dispersions are Attractive Gels, Not Repulsive Wigner Glasses: A Critical Commentary
Yogesh M Joshi, Shrajesh Patel, Khushboo Suman
An aqueous dispersion of Laponite has been studied in the literature for over the past three decades. Typically, the aqueous dispersion of Laponite undergoes incessant evolution of…
Large Amplitude Oscillatory Shear Study of a Colloidal Gel at the Critical State
Khushboo Suman, Sachin Shanbhag, Yogesh M. Joshi
We investigate the nonlinear viscoelastic behavior of a colloidal dispersion at the critical gel state using large amplitude oscillatory shear (LAOS) rheology. The colloidal gel at…
Gel-Sol Transition of Thermoresponsive Poly(vinyl alcohol) Solution: Validation of the Universal Critical Scaling Relations
Tulika Bhattacharyya, Khushboo Suman, Yogesh M. Joshi
While undergoing gelation transition, a material passes through a distinctive state called the critical gel state. In the neighborhood of this critical gel state, how viscosity, eq…
Effect of sodium pyrophosphate and understanding microstructure of aqueous LAPONITE(R) dispersion using dissolution study
Khushboo Suman, Mohit Mittal, Yogesh M Joshi
We investigate physical origin of ergodicity breaking in an aqueous colloidal dispersion of synthetic hectorite clay, LAPONITE(R), by performing dissolution and rheological experim…
On the universality of the critical scaling exponents during sol-gel transition
Khushboo Suman, Yogesh M. Joshi
The evolution of viscoelastic properties near the sol-gel transition is studied by performing oscillatory rheological measurements on two different types of systems: a colloidal di…
Analyzing Onset of Nonlinearity of a Colloidal Gel at the Critical Point
Khushboo Suman, Yogesh M. Joshi
In this work we study onset of nonlinear rheological behavior of a colloidal dispersion of a synthetic hectorite clay, Laponite, at the critical gel state while undergoing sol-gel…
In Situ Ion Induced Gelation of Colloidal Dispersion of Laponite: Relating Microscopic Interactions to Macroscopic Behavior
Rashmi P. Mohanty, Khushboo Suman, Yogesh M. Joshi
Aqueous dispersion of Laponite, when exposed to carbon dioxide environment leads to in situ inducement of magnesium and lithium ions, which is, however absent when dispersion is ex…
Microstructure and Soft Glassy Dynamics of Aqueous Laponite Dispersion
Khushboo Suman, Yogesh M. Joshi
Synthetic hectorite clay Laponite RD/XLG is composed of disk-shaped nanoparticles that acquire dissimilar charges when suspended in an aqueous media. Owing to their property to spo…
