Flow-induced currents in nanotubes: a Brownian dynamics approach
Moumita Das, Sriram Ramaswamy, A. K. Sood +1
Motivated by recent experiments [Science {\bf 299}, 1042 (2003)] reporting that carbon nanotubes immersed in a flowing fluid displayed an electric current and voltage, we numerical…
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…
Electron Paramagnetic Resonance Study of Phase Segregation in NdSrMnO
Janhavi P. Joshi, A. K. Sood, S. V. Bhat +2
We present results of an electron paramagnetic resonance (EPR) study of NdSrMnO with x = 0.5 across the paramagnetic to ferromagnetic, insulator to metal transition…
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…
Phase behaviour of a hard sphere colloidal system in the presence of an external laser field
Pinaki Chaudhuri, Ajay K. Sood, H. R. Krishnamurthy
We study the phase behaviour of a two-dimensionally confined hard sphere colloidal system in the presence of a periodic light field of two interfering laser beams using Monte Carlo…
Laser induced freezing of charge stabilized colloidal system
Chinmay Das, A. K. Sood, H. R. Krishnamurthy
We present results from an extensive simulational study of the modulated liquid crystal transition in a 2-d charge-stabilized colloid subject to a 1-d laser f…
