Enhanced scattering induced by electrostatic correlations in concentrated solutions of salt-free dipolar and ionic polymers
Rajeev Kumar, Bradley Lokitz, Timothy E. Long +1
We present a generalized theory for studying static monomer density-density correlation function (structure factor) in concentrated solutions and melts of dipolar as well as ionic…
Charge regulation and local dielectric function in planar polyelectrolyte brushes
Rajeev Kumar, Bobby G. Sumpter, S. Michael Kilbey
Understanding the effect of inhomogeneity on the charge regulation and dielectric properties, and how it depends on the conformational characteristics of the macromolecules is a lo…
Breakdown of inverse morphologies in charged diblock copolymers
Monojoy Goswami, Rajeev Kumar, Bobby G. Sumpter +1
Brownian Dynamics simulations are carried out to understand the effect of temperature and dielectric constant of the medium on microphase separation of charged-neutral diblock copo…
Phase Separation in Symmetric Mixtures of Oppositely Charged Rodlike Polyelectrolytes
Rajeev Kumar, Debra Audus, Glenn H. Fredrickson
Phase separation in salt-free symmetric mixtures of oppositely charged rodlike polyelectrolytes is studied using quasi-analytical calculations. Stability analyses for the isotropic…
Origin of translocation barriers for polyelectrolyte chains
Rajeev Kumar, M. Muthukumar
For single-file translocations of a charged macromolecule through a narrow pore, the crucial step of arrival of an end at the pore suffers from free energy barriers, arising from c…
Theory of polyzwitterion conformations
Rajeev Kumar, Glenn H. Fredrickson
Conformational characteristics of polyzwitterionic molecules in aqueous solutions are investigated using the variational method. Analytical relations are derived for the radius of…
