Swollen and collapsed lyotropic lamellar rheology

Rheological investigation of thermal transitions in vesicular dispersion

“…The dispersion is gel-like with a slight decay of the moduli until 5.5 h. More evidence is drawn from the rheogram (inset of Fig. 10) which characterize close-packed MLVs [29,31].…”

Development of curcumin loaded sodium hyaluronate immobilized vesicles (hyalurosomes) and their potential on skin inflammation and wound restoring

“…Empty 0.1 and 0.5hyalurosomes probably due to the high phospholipid concentration [24]. In the spectrum of hyalurosomes, G' values was much higher than G'' (especially for 0.5hyalurosomes) and the cross-over point was shifted toward frequencies lower than 0.1 Hz, indicating a more structured and strong (weak gel) system, with respect to liposomes, probably related to the polymer-vesicle network ( Figure 3E) [25,26].…”

Temperature and concentration effects on supramolecular aggregation and phase behavior for poly(propylene oxide)–b-poly(ethylene oxide)–b-poly(propylene oxide) copolymers of different concentration in aqueous mixtures, 2

“…9 reports the viscoelasticity of lamellar dispersion, D + W, in which G 0 dominates and maintains a constant value, while G 00 increases smoothly until the maximum experimental frequency is reached. This response results in a strong elastic gel-like behavior which is characteristic of a lamellar organization consisting of densely packed vesicles [95]. By the perusal of Fig.…”
