Buckling of a linear chain of hard spheres
We extend a previous analysis of the buckling properties of a linear chain of hard spheres between hard walls under transverse harmonic confinement. Two regimes are distinguished—low compression, fo…

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.
Columnar structures of soft spheres: metastability and hysteresis
Previously we reported on the stable (i.e. minimal enthalpy) structures of soft monodisperse spheres in a long cylindrical channel. Here, we present further simulations, which significantly extend the…
Demonstration and interpretation of “scutoid” cells in a quasi-2D soap froth
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 that such…
Geompack
A new virtual seminar series called GEOMPACK (geompack.com) aims to bring together researchers from a range of disciplines (physics, materials, biology, mathematics, computer science). The series focu…
Theory of rotational columnar structures of soft spheres
There is a growing interest in cylindrical structures of hard and soft particles. A promising new method to assemble such structures has recently been introduced by Lee et al. [T. Lee, K. Gizynski, an…
