Some rheological properties of nonionic surfactant vesicles and the determination of surface hydration
Article Abstract:
Capillary viscosimetry was used in studying dilute aqueous nonionic surfactant vesicle dispersions formed from hexadecyl diglycerol ether (C16G2) or sorbitan monostearate (Span 60). Polyhedral or spherical structures are formed when the ratio of C16G2, cholesterol or Solulan C24 are varied. It has been observed that there is a little change in the relative viscosity of spherical/tubular niosome dispersions as the temperature increases. However, there is a significant reduction in the relative viscosity of polyhedral dispersions. This indicates that the shape of the dispersions become spherical.

Diffusion and sorption of methanol and water in nafion using time-resolved Fourier transform infrared-attenuated total reflectance spectroscopy
Article Abstract:
Time-resolved Fourier transform infrared-attenuated total reflectance (FTIR-ATR) spectroscopy is used for measuring the diffusion and sorption of methanol and water in Nafion 117. The studies have shown that the increase in methanol flux is attributed to methanol sorption in the membrane.
