“…They are two-phase materials consisting mainly of gas, with consequently a low density but also a large surface area. As a result of these remarkable properties, aqueous foams are desirable, for example, in personal hygiene and food products and are also integral in industrial processes such as enhanced oil-recovery [3,4] and froth flotation for mineral separation, paper deinking, waste water treatment and soil remediation [5][6][7][8][9]. The process of froth flotation, in particular, is driven by how the surfaces within a foam interact with solid particles and objects, and gaining a better understanding of this interaction is one of the main objectives of this work.…”
