The Influence of Structure and Morphology on Ion Permeation Behaviour in Commercial Silicone Hydrogel Contact Lenses

Saez-Martinez, Virginia; Mann, Aisling; Lydon, Fiona; Molock, Frank; Layton, Siân A.; Toolan, Daniel T. W.; Howse, Jonathan R.; Topham, Paul D.; Tighe, Brian J.

The importance of the microstructure on the permeability of silicone hydrogels is widely appreciated but is poorly understood and minimally investigated. In contrast with most conventional hydrogels, the water content and water structuring within silicone hydrogels cannot be solely used to predict their permeability. To ensure comfort and eye health,…

Rapid Stabilization of Immiscible Fluids using Nanostructured Interfaces via Surfactant Association

Niroobakhsh, Zahra; LaNasa, Jacob A.; Belmonte, Andrew; Hickey, Robert J.

Surfactant molecules have been extensively used as emulsifying agents to stabilize immiscible fluids. Droplet stability has been shown to be increased when ordered nanoscale phases form at the interface of the two fluids due to surfactant association. Here, we report on using mixtures of a cationic surfactant and long chained…

The structure of spray-dried detergent powders

Farshchi, Amin; Hassanpour, Ali; Bayly, Andrew E.

The complex multiscale structure of spray dried detergent granules has been characterized using a complementary range of techniques including scanning electron microscopy (SEM), image analysis, wide angle and small angle X-ray scattering (WAXS, SAXS) and X-ray microtomography. A complex composite structure is revealed due to the multiphase nature of the…
