Chitosan-SDS interactions at a solid-liquid interface: effects of surfactant concentration and ionic strength
Article Abstract:
An examination is made of the effect of ionic strength on adsorption of chitosan on mica as well as the effect of addition of an anionic surfactant, SDS, on the adsorbed chitosan layers. Chemical surface analysis (ESCA) and surface force measurements (SFA) demonstrate that an elevated salt concentration leads to larger adsorbed amounts and thicker adsorption layers of this cationic polyelectrolyte.

Viscoelastic properties of isomeric alkylglucoside surfactants studied by surface light scattering
Article Abstract:
A study to investigate the adsorption behavior of non-ionic sugar surfactants at the air/liquid interface using surface light scattering (SLC) by capillary waves is performed. Viscoelastic properties of monolayers formed by octyl beta-glucoside, octyl alpha-glucoside and 2-ethylhexal alpha-glucoside surfactants were quantified at submicellar concentrations.

X-ray photoelectron spectroscopy in the study of polyelectrolyte adsorption on mica and cellulose
Article Abstract:
The absolute amount of cationic polyelectrolytes that adsorb on mica and cellulose surfaces in aqueous media is estimated by X-ray photoelectron spectroscopy. The nonelectrostatic interactions are the main contributors to the adsorption of polyelectrolytes on cellulose, but electrostatic effects also take part in the adsorption mechanism.
