Colloidal Gas Aphrons (CGAs) are microbubbles with a stable air core, surrounded by a hydrogen-bonded aqueous shell and surfactant bilayers. They are generated in a specially designed baffled generator using surfactant solutions at high rotational speeds exceeding a critical threshold. While CGAs ha...
