This article reviews the state of the art of the studies on charge regulation (CR) effects in
flexible weak polyelectrolytes (FWPE). The characteristic of FWPE is the strong coupling of …

We study the effects of charge-regulated acid/base equilibrium on the swelling of
polyelectrolyte gels by considering a combination of the Poisson–Boltzmann theory and a …

Recent experiments on weak polyelectrolyte brushes found marked shifts in the effective p K
a that are linear in the logarithm of the salt concentration. Comparing explicit-particle …

We used computer simulations to study the equilibrium swelling of weak (pH-responsive)
polyelectrolyte hydrogels as a function of pH and salt concentration in a supernatant …

We use particle-based, coarse-grained simulations to study the influence of divalent
counterions on a weak polyelectrolyte brush. Our simulations show a profound influence of …

Healthcare devices for the human body have seen continuous evolution, from external wear
to wearables, and now to entirely concealed placements. The gastrointestinal (GI) tract offers …

Polyelectrolyte gels, made by crosslinking of ion-containing polymers, showcase
extraordinary swelling capabilities, with their volumes expanding up to 100 times in salt-free …

Mixing of oppositely charged polyelectrolytes can result in phase separation into a polymer-
poor supernatant and a polymer-rich polyelectrolyte complex (PEC). We present a new …

A method to synthesize stable, raspberry-like nanoparticles (NPs), using surface grafting of
poly (glycidyl methacrylate)(PGMA) brushes on a polystyrene (PS) core with varying grafting …

We study the influence of core–shell morphology on the structural characteristics of
nanogels. Using computer simulations, we examine three different types of systems …
