Characteristics of the secondary relaxation process in soft colloidal suspensions
Debasish Saha, Yogesh M Joshi, Ranjini Bandyopadhyay
A universal secondary relaxation process, known as the Johari-Goldstein (JG) -relaxation process, appears in glass formers. It involves all parts of the molecule and is particul…
Effect of electrolyte on the microstructure and yielding of aqueous dispersions of colloidal clay
Samim Ali, Ranjini Bandyopadhyay
Na-montmorillonite is a natural clay mineral and is available in abundance in nature. The aqueous dispersions of charged and anisotropic platelets of this mineral exhibit non-ergod…
Kinetics of the glass transition of fragile soft colloidal suspensions
Debasish Saha, Yogesh M. Joshi, Ranjini Bandyopadhyay
Microscopic relaxation timescales are estimated from the autocorrelation functions obtained by dynamic light scattering experiments for Laponite suspensions with different concentr…
