How solid–liquid adsorption affects the liquid–vapor interface in pores

Vadose Zone Journal, 2022
The augmented Young–Laplace (AYL) equation has been widely used to describe the liquid–vapor interfaces affected by capillarity and adsorption, particularly in nanoporous or clay minerals where strong adsorptive interaction prevails.
