Research Highlights
Images from recent publications that highlight our research.
Line slip arrangements observed in wet foams
The image on the left shows a perfect “maximal-contact” structure while the image on the right is a “line-slip” arrangment in which there are gaps between bubbles.
Scutoid in foam
Recently a novel type of epithelial cell has been discovered and dubbed the ‘scutoid’. It is induced by curvature of the bounding surfaces. We show by simulations and experiments (above image) that such cells are to be found in a dry foam subjected to this boundary condition.
