Slow Kinetics of Capillary Condensation in Confined Geometry: Experiment and Theory

, 2001
When two solid surfaces are brought in contact, water vapor present in the ambient air may condense in the region of the contact to form a liquid bridge connecting the two surfaces : this is the so-called capillary condensation.
