Physicochemical Effects in Aging Aqueous Laponite Suspensions
A. Shahin, Yogesh M Joshi
We study aging behavior of aqueous suspension of Laponite as a function of concentration of Laponite, concentration of salt, time elapsed since preparation of suspension (idle time…
Hyper-aging Dynamics of Nano-clay Suspension
A. Shahin, Yogesh M Joshi
Aqueous suspension of nanoclay Laponite undergoes structural evolution as a function of time, which enhances its elasticity and relaxation time. In this work we employ effective ti…
Interface Induced Anisotropy and nematic glass/gel state in Jammed Aqueous Laponite Suspensions
A. Shahin, Yogesh M Joshi, S. Anantha Ramakrishna
Aqueous suspensions of Laponite, a system composed of disk-like nanoparticles, are found to develop optical birefringence over several days, well after the suspensions solidified d…
Delayed solidification of soft glasses: New experiments, and a theoretical challenge
Yogesh M. Joshi, A. Shahin, Michael E. Cates
When subjected to large amplitude oscillatory shear stress, aqueous Laponite suspensions show an abrupt solidification transition after a long delay time tc. We measure the depende…
Prediction of long and short time rheological behavior in soft glassy materials
A. Shahin, Yogesh M Joshi
We present an effective time approach to predict long and short time rheological behavior of soft glassy materials from experiments carried out over practical time scales. Effectiv…
Irreversible Aging Dynamics and Generic Phase Behavior of Aqueous Suspensions of Laponite
A. Shahin, Yogesh M. Joshi
In this work we study the aging behavior of aqueous suspension of Laponite having 2.8 weight % concentration using rheological tools. At various salt concentration all the samples…
