Polyelectrolytes with ionic groups are abundant in nature and essential in life. Counterions
can be released into a solution and leave charges on polyelectrolyte chains, making the …

Polyelectrolytes continue to find wide interest and application in science and engineering,
including areas such as water purification, drug delivery, and multilayer thin films. We have …

In recent experiments, the “local pH” near polyelectrolyte chains was determined from the
shift in the effective acidity constant of fluorescent pH indicators attached to the …

The dynamics of adsorption and desorption of counterions on a polyelectrolyte chain in
aqueous solution is studied at a single molecular level. The investigation is through the …

Using sodium polystyrene sulfonate (NaPSS) and quarternized poly 4-vinylpyridine
(QP4VP) as model systems, the chain conformation of polyelectrolytes under finite salt …

We report chain self-diffusion and viscosity data for sodium polystyrene sulfonate (NaPSS)
in semidilute salt-free aqueous solutions measured by pulsed-field gradient NMR and …

The high cost of synthetic polymers has been a key impediment limiting the widespread
adoption of polymer drag reduction techniques in large-scale engineering applications, such …

Charged macromolecules under flow are ubiquitous, and the important physics inside is not
yet well understood. In this study, single-molecule fluorescence spectroscopy methods are …

For the purpose of understanding the molecular origins of the rheological properties of
polyelectrolyte solutions, an in situ investigation into the distribution of counterions of a …

Switchable inversion of chirality between opposite handedness by varying pH is discovered
for a histidine pendant polymer, polymethyl (4-vinylbenzoyl) histidinate (PBHis), as …
