After publication of the above article we became aware of the publications of the group of Alfonso M. Gañán-Calvo, Grupo de Mecánica de Fluidos, Escuela Superior de Ingenieros, Universidad de Sevilla, Spain.
Using a flow-focusing technique Gañán-Calvo et al. produced monodisperse gas bubbles (diameter 60 µm) and found that these self-assemble into perfectly ordered lattices in what the authors call mesocrystal foam (ref. A. M. Gañán-Calvo and J. M. Gordillo, Phys. Rev. Lett., 2001, 87, 274501). Of particular interest is the interplay of drainage and coarsening in these random ordered lattices (ref. A. M. Gañán-Calvo, J. M. Fernández and A. Marquez Oliver, Appl. Phys. Lett., 2004, 84, 4989).
Our general findings are consistent with those of Alfonso M. Gañán-Calvo’s group, with the addition of a clear identification of the type of packing encountered and some of the defects, the analysis of terrace structures which indicate that ordering is indeed a bulk property of wet monodisperse foams of bubble diameter less than 500 microns, and the interpretation of images by detailed ray tracing computations.
The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
