En las fronteras de la Materia Condensada

A simple model based on an approximation of the droplet-like 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 behavior is predicted from the values of two dimensionless parameters: D_* (the reduced asymptotic strength of the fluid-adsorber interaction, a function of temperature) and R_* (the reduced radius of the pore). The phenomenon of hysteresis inherently related to capillary condensation is discussed.
