Figure 4: Various bubble patterns.
From: A general patterning approach by manipulating the evolution of two-dimensional liquid foams
(a) Triangular bubble arrays. (b) Square arrayed round bubbles. (c) Cross-shaped bubble arrays. (d) Octagonal bubble arrays. (e) Bubble patterning consisting of hexagon and octagon. (f) Discrete dodecagonal bubble arrays. (g) Peace-dove-shaped bubble arrays. (h) Conformal pattern of a hexagonal bubble arrays with rotational symmetry26, consisting of a dodecagonal bubble and hexagonal bubbles of different size. All scale bars, 100 μm.
