Wetting and Prewetting on Ceramic Surfaces
The stabilization of nanoscale surficial amorphous films (SAFs) for Bi2O3 on ZnO, VOx on TiO2, SiOx on Si, and several other oxide systems provides evidence for the existence of prewetting phenomena with analogies in water and other simple systems, as well as the stabilization of intergranular amorphous films in ceramics. Experimental results show that in the subeutectic regime, the equilibrium...
متن کاملLine and boundary tensions on approach to the wetting transition.
A mean-field density-functional model often used in the past in the study of line and boundary tensions at wetting and prewetting transitions is reanalyzed by extensive numerical calculations, approaching the wetting transition much more closely than had previously been possible. The results are what are now believed to be definitive for the model. They include strong numerical evidence for the...
متن کاملPrewetting transition in supercritical argon
2014 From the low frequency measurements of the dielectric constant of ultra low impurity liquid argon, we obtain the density of the liquid in the vicinity of the critical point. Along the 50 atm isobar slightly above the critical temperature, we find apparent discontinuity in the density, suggesting proximity to a prewetting transition. A simple mean field theoretical analysis provides a quali...
متن کاملCross-over between first-order and critical wetting at the liquid-vapour interface of n-alkane/methanol mixtures: tricritical wetting and critical prewetting
A mean-field theory is presented which describes the basic observations of recent experiments revealing rich wetting behaviour of n-alkane/methanol mixtures at the liquid-vapour interface. The theory is based on a microscopic lattice-gas model from which a Cahn-Landau approach is derived. Besides the physics associated with the short-range components of the intermolecular interactions, the effe...
متن کاملExtraordinary wetting phase diagram for mixtures of Bose-Einstein condensates.
The possibility of wetting phase transitions in Bose-Einstein condensed gases is predicted on the basis of Gross-Pitaevskii theory. The surface of a binary mixture of Bose-Einstein condensates can undergo a first-order wetting phase transition upon varying the interparticle interactions, using, e.g., Feshbach resonances. Interesting ultra-low-temperature effects shape the wetting phase diagram....
