Capillary Condensation and Capillary Sublimation in Meso- and Nanopores

 Capillary condensation of argon (triangles) and n-hexane (squares) in silicon nanopores with mean pore diameter of 8 nm as documented by a sorption isotherm measurement recorded at a temperature of 87 K and 273 K, respectively. The insets illustrate film growth at the pore walls which upon vapour pressure increase culminates in capillary condensation, the formation of liquid bridges with concave menisci in the pore centres.
