“…Aqueous foams are complex two-phase materials consisting of gas bubbles, liquid films and channels [1]. The interaction between a soap film and a solid object or between particles and an aqueous foam is important in froth flotation for mineral separation, paper deinking, waste water treatment and soil remediation [2,3,4,5,6]. The efficiency of the flotation process depends on the interaction that occurs between a foam's films and the particles it needs to carry and those it needs to leave behind.…”

“…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.…”

“…A water contact angle test was carried out to study the change in the Au/β-CD-CN surface property. As shown in Figure 5 , it is obvious that the β-CD modified CN has a hydrophobic surface with a contact angle of about 89.0°, leading to better adsorption ability to oxygen and thus improved photocatalytic activity of H 2 O 2 production [ 37 ].…”

“…The photocatalytic activity of H 2 O 2 production over M/β-CD-CN composite was tested under visible light and a spectrophotometric method was used to quantify the H 2 O 2 concentrations [ 37 ]. The standard curve indicated that the concentration of H 2 O 2 and absorbance exhibited a good linear relationship with R-square of 0.9988 ( Figure S1 ).…”
