Inside Cover: How Rigid Rods Self-Assemble at Curved Surfaces (Angew. Chem. Int. Ed. 2/2009)
Superstable foams that contain air bubbles stabilized by modified, rigid CaCO3 rods are reported by W. Liu, S. Stoyanov, and co-workers in their Communication on page 378 ff. The very high stability and stiffness of the rod-stabilized bubbles means that their spherical shape is retained when dried on glass substrates. Despite the massive difference in length, the surface pattern of a 120 micrometer bubble with 25 micrometer rods is similar to that of 10 meter logs on a river surface.
