Fig. 1: Foamed emulsion setup.
a Storage (down triangles) and loss (up triangles) moduli of the emulsions used as the foam continuous phases as a function of oil volume fraction ϕ. The dashed line shows the expected scaling of \({G}^{{\prime} } \, \approx \, \phi (\phi -{\phi }^{*})\) with ϕ* = 0.635 from ref. 19, which describes the data well. In the following, we use G0 for \({G}^{{\prime} }\) for the emulsion elastic modulus. The squares are Cael calculated using 〈R〉 = 0.5 mm and a surface tension of 30 mN/m and the solid line guides to Cael = 1. b Schematic drawing of the sample generation from 3D foam to the quasi-2D foam. The gap between the plates is 1 mm. c Photograph of foam after generation seen under the microscope. The edge size is 830 μm. d Perspective view of a quasi-2D foam. e Top view of foam with its skeleton overlaid in red. The edge size is 30 mm.
