Dynamics and complex formation in charged and uncharged Ficoll70 solutions
Swomitra Palit, Anand Yethiraj
We apply pulsed-field-gradient NMR (PFG NMR) technique to measure the translational diffusion for both uncharged and charged polysaccharide (Ficoll70) in water. Analysis of the dat…
Contrasting the dynamics of elastic and non-elastic deformations across an experimental colloidal Martensitic transition
Saswati Ganguly, Priti S. Mohanty, Peter Schurtenberger +2
We present a framework to segregate the roles of elastic and non-elastic deformations in the examination of real-space experiments of solid-solid Martensitic transitions. The Marte…
Electric-field-induced turbulent energy cascade in an oil-in-oil emulsion
Atul Varshney, Mayur Sathe, Shankar Ghosh +3
We observe electro-hydrodynamically driven turbulent flows at low Reynolds numbers in a two-fluid emulsion consisting of micron-scale droplets. In the presence of electric fields,…
Clusters in sedimentation equilibrium for an experimental hard-sphere-plus-dipolar Brownian colloidal system
Hugh D. Newman, Anand Yethiraj
In this work, we use structure and dynamics in sedimentation equilibrium, in the presence of gravity, to examine, confocal microscopy, a Brownian colloidal system in the pres…
Dynamics, crystallization and structures in colloid spin coating
Moorthi Pichumani, Payam Bagheri, Kristin M. Poduska +2
Spin coating is an out-of-equilibrium technique for producing polymer films and colloidal crystals quickly and reproducibly. In this review, we present an overview of theoretical a…
Diffusion NMR study of complex formation in membrane-associated peptides
Suliman Barhoum, Valerie Booth, Anand Yethiraj
Pulsed-field-gradient nuclear magnetic resonance (PFG-NMR) is used to obtain the true hydrodynamic size of complexes of peptides with sodium dodecyl sulfate SDS micelles. The pepti…
Effect of order-parameter fluctuations on the Halperin-Lubensky-Ma first-order transition in superconductors and liquid crystals
Igor F. Herbut, Anand Yethiraj, John Bechhoefer
We show that order-parameter fluctuations in a good type-I superconductor or a liquid crystal always increase the size of the first-order transition. This behavior is eventually ch…
External-field-induced tricritical point in a fluctuation-driven nematic-smectic-A transition
Ranjan Mukhopadhyay, Anand Yethiraj, John Bechhoefer
We study theoretically the effect of an external field on the nematic-smectic-A (NA) transition close to the tricritical point, where fluctuation effects govern the qualitative beh…
