Slow crystallisation of a monodisperse foam stabilised against coarsening

Meagher, Aaron J.; Whyte, David; Banhart, John; Hutzler, Stefan; Weaire, Denis; García-Moreno, Francisco

The evolution of a three-dimensional monodisperse foam was investigated using X-ray tomography over the course of seven days. The coarsening of the sample was inhibited through the use of perfluorohexane gas. The internal configuration of bubbles is seen to change markedly, evolving from a disordered arrangement towards a more ordered state. We chart this ordering process through the use of the coordination number, the bond orientational order parameter (BOOP) and the translational order parameter.
