Ostwald ripening is a phenomenon observed in systems containing multiple gas bubbles. It involves the diffusion of gas from smaller bubbles to larger ones through the thin liquid films (lamellae) that separate the bubbles . This process is driven by the pressure difference between smaller and larger bubbles, as explained by Laplace's law, the pressure inside a bubble is inversely proportional to its radius. Consequently, smaller bubbles experience higher internal pressure than larger ones. As a consequence, gas from the smaller bubbles diffuses through the liquid films and merges into the larger bubbles. This leads to the shrinking of the smaller bubbles and the continued growth of the larger ones, resulting in a gradual increase in the size of the larger bubbles at the expense of the smaller ones. Ostwald ripening occurs due to the pressure discrepancy between bubbles and the diffusion of gas through the liquid films, causing a redistribution of gas and a change in bubble sizes within the system.
