Magnéli Phases

The observation of reductive decomposition with SEC-current-time-temperature curves on the binary line V2O5-Nb2O5 is a useful method to determine qualitatively and quantitatively (“quasi in situ”) the known ternary coexistence regions. By reduction of VO2 the Magneli-Phases VnO2n-1 are generated. The method is generally applicable and allows rapid information by reductive decompositon or oxidative formation in coexistence regions.The conditions of decomposition can be optimized for a given system. Slow solid-gas equilibria are not detectable by this method.

Oil In Water

It is well-established that oil-in-water creams can be stabilised through the formation of lamellar liquid crystal structures in the continuous phase, achieved by adding (emulsifier) mixtures comprising surfactant(s) combined (of necessity) with one or more co-surfactants. There is little molecular-level understanding, however, of how the microstructure of a cream is modulated by changes in co-surfactant and of the ramifications of such changes on cream properties. We investigate here the molecular architectures of oil-free, ternary formulations of water and emulsifiers comprising sodium dodecyl sulfate and one or both of the co-surfactants hexadecanol and octadecanol, using microscopy, small-angle and wide-angle X-ray scattering and small-angle neutron scattering. We then deploy these techniques to determine how the structures of the systems change when liquid paraffin oil is added to convert them to creams, and establish how the structure, rheology, and stability of the creams is modified by changing the co-surfactant. The ternary systems and their corresponding creams are shown to contain co-surfactant lamellae that are subtly different and exhibit different thermotropic behaviours. The lamellae within the creams and the layers surrounding their oil droplets are shown to vary with co-surfactant chain length. Those containing a single fatty alcohol co-surfactant are found to contain crystallites, and by comparison with the cream containing both alcohols suffer adverse changes in their rheology and stability.
