Foam lamella at air–liquid interface

A *foam lamella at the air–liquid interface* refers to the thin liquid film that exists between two air bubbles within a foam structure, specifically at the boundary where the liquid phase meets air. These lamellae are stabilized by surfactant molecules that adsorb at the interface, reducing surface tension and aiding foam formation and stability[1][2][3][4]. The lamella acts as a double layer of surfactant, separating the air phases, and its thickness and stability are key factors in the longevity of foams[1][5]. Lamellae play a fundamental role in materials science, chemistry, and various industries (cosmetics, food, cleaning, flotation), but they are not biological or therapeutic targets and do not represent discrete molecular entities[1][4][5].
