Simple model of capillary condensation in cylindrical pores

Mostrar todas las versiones(3)

A simple model based on an approximation of the dropletlike model is formulated for studying adsorption of fluids into cylindrical pores. This model yields a nearly universal description of capillary condensation transitions for noble gases confined by alkali metals. The system’s thermodynamical beh...

This model yields a nearly universal description of capillary condensation transitions for noble gases confined by alkali metals.
