Effective charge, collapse and the critical point of a polyelectrolyte chain
Arindam Kundagrami, M. Muthukumar
The charge of a polyelectrolyte (PE) controls myriads of phenomena in biology, biotechnology, and materials science, but still remains elusive from an understanding. Considering th…
The collapse of linear polyelectrolyte chains in a poor solvent: When does a collapsing polyelectrolyte collect its counter ions?
Peter Loh, G. Roshan Deen, Doris Vollmer +4
In order to better understand the collapse of polyions in poor solvent conditions the effective charge and the solvent quality of the hypothetically uncharged polymer backbone need…
Counterion adsorption on flexible polyelectrolytes: comparison of theories
Rajeev Kumar, Arindam Kundagrami, M. Muthukumar
Counterion adsorption on a flexible polyelectrolyte chain in a spherical cavity is considered by taking a "permuted" charge distribution on the chain so that the "adsorbed" counter…
Theory of competitive counterion adsorption on flexible polyelectrolytes : Divalent salts
Arindam Kundagrami, M. Muthukumar
Counterion distribution around an isolated flexible polyelectrolyte in the presence of a divalent salt is evaluated using the adsorption model [M. Muthukumar, J. Chem. Phys. {\bf 1…
Continuum Theory of Polymer Crystallization
Arindam Kundagrami, M. Muthukumar
We present a kinetic model of crystal growth of polymers of finite molecular weight. Experiments help to classify polymer crystallization broadly into two kinetic regimes. One is o…
The Structure of TGB Phases
Arindam Kundagrami, T. C. Lubensky
We study the transition from the cholesteric phase to two TGB phases near the upper critical twist : the Renn-Lubensky TGB phase, with layer normal rotating in a pl…
