TLDR
In this paper, the authors investigate theoretically charge regulation of weakly dissociating polyacids by potentiometric titration of their aqueous solutions, by treating deprotonation and cation binding to the polyacid as reversible reactions in their model, the ionization constant of acid groups along the polyacid chain is adjusted from its intrinsic value by electrostatic correlations.About:

Driving force and pathway in polyelectrolyte complex coacervation
Shensheng Chen,Zhen-Gang Wang +1 more
TL;DR: In this paper , the temperature dependence in the dielectric constant of water can be exploited to extract the solvent entropy contribution in the electrostatic interactions, thereby resolving a major discrepancy between experiments and coarse-grained model studies concerning the thermodynamic driving force (i.e., entropy vs. energy) for polyelectrolyte complex coacervation.

Hysteretic Swelling/Deswelling of Polyelectrolyte Brushes and Bilayer Films in Response to Changes in pH and Salt Concentration.
TL;DR: In this article, a quartz crystal microbalance with dissipation (QCM-D) was used to investigate the swelling/de-swelling and hysteresis in brushes of weakly ionizable polyanion poly(acrylic acid) (PAA) brushes and bilayers containing a PAA brush and a poly(ethylene imine) (PEI) overlayer.

Classical Electrostatics in Biology and Chemistry
Barry Honig,Anthony Nicholls +1 more
TL;DR: A major revival in the use of classical electrostatics as an approach to the study of charged and polar molecules in aqueous solution has been made possible through the development of fast numerical and computational methods to solve the Poisson-Boltzmann equation for solute molecules that have complex shapes and charge distributions.
