Aggregation and gelation in hydroxypropylmethyl cellulose aqueous solutions.
In this work we present an analysis of the thermal behavior of hydroxypropylmethyl cellulose aqueous solutions, from room temperature to higher temperatures, above gelation. We focus on significantExpand

On the role of hydrophobic interactions in cellulose dissolution and regeneration: Colloidal aggregates and molecular solutions
The development of strategies for dissolution and regeneration of cellulose constitutes an increasingly active research field due to the direct relevance for many production processes andExpand

Compaction and Decompaction of DNA in the Presence of Catanionic Amphiphile Mixtures
The dissociation of DNA-cationic surfactant complexes with the addition of a negative amphiphile was studied by fluorescence microscopy (FM). The unfolding of DNA molecules previously compacted withExpand

Vesicle Formation and General Phase Behavior in the Catanionic Mixture SDS-DDAB-Water . The Anionic-Rich Side
Catanionic mixtures are aqueous mixtures of oppositely charged surfactants which display novel phase behavior and interfacial properties in comparison with those of the individual surfactants. OneExpand

Self-assembly in mixtures of a cationic and an anionic surfactant: the sodium dodecyl sulfate-didodecyldimethylammonium bromide-water system
The phase equilibria of the sodium dodecyl sulfate (SDS)-didodecyldimethylammonium bromide (DDAB)-water system have been studied by water deuteron NMR and polarizing microscopy methods at 40 o C. 1 HExpand

Polymer-vesicle association.
Mixed polymer-surfactant systems have been intensively investigated in the last two decades, with the main focus on surfactant micelles as the surfactant aggregate in interaction. The main types ofExpand

Network formation of catanionic vesicles and oppositely charged polyelectrolytes. Effect of polymer charge density and hydrophobic modification.
In nonequimolar solutions of a cationic and an anionic surfactant, vesicles bearing a net charge can be spontaneously formed and apparently exist as thermodynamically stable aggregates. TheseExpand

Effect of headgroup on DNA-cationic surfactant interactions.
The interaction behavior of DNA with different types of hydroxylated cationic surfactants has been studied. Attention was directed to how the introduction of hydroxyl substituents at the headgroup ofExpand
