Speckle-visibility spectroscopy: A tool to study time-varying dynamics
R. Bandyopadhyay, A. S. Gittings, S. S. Suh +2
We describe a multispeckle dynamic light scattering technique capable of resolving the motion of scattering sites in cases that this motion changes systematically with time. The me…
Effect of silica colloids on the rheology of viscoelastic gels formed by the surfactant cetyl trimethylammonium tosylate
R. Bandyopadhyay, A. K. Sood
The effects of the addition of sub-micrometer sized colloidal silica spheres on the linear and nonlinear rheology of semi-dilute solutions of a viscoelastic gel are studied. For a…
Effect of Screening of Intermicellar Interactions on the Linear and Nonlinear Rheology of a Viscoelastic Gel
Ranjini Bandyopadhyay, A. K. Sood
We report our studies of the linear and nonlinear rheology of aqueous solutions of the surfactant cetyl trimethylammonium tosylate (CTAT) with varying amounts of sodium chloride (N…
Rheology of Semi-dilute Solutions of Calf-thymus DNA
Ranjini Bandyopadhyay, A. K. Sood
We study the rheology of semi-dilute solutions of the sodium salt of calf-thymus DNA in the linear and nonlinear regimes. The frequency response data can be fitted very well to the…
