We present an overview of recent advances in the understanding of foam structure and
energy and their dependence on liquid volume fraction. We consider liquid foams in …

Gas-liquid foams are important in applications ranging from oil recovery and mineral
flotation to food science and microfluidics. Beyond their practical use, they represent an …

D'Arcy Thompson emphasised the importance of surface tension as a potential driving force
in establishing cell shape and topology within tissues. Leaf epidermal pavement cells grow …

In two chapters of his book On Growth and Form, D'Arcy Thompson used numerous
biological and physical observations to show how principles from mathematics and physics …

Many systems, including biological tissues and foams, are made of highly packed units
having high deformability but low compressibility. At two dimensions, these systems offer …

As epithelial tissues develop, groups of cells related by descent tend to associate in clonal
populations rather than dispersing within the cell layer. While this is frequently assumed to …

In a confluent, single-cell tissue layer, we show that cell shapes and statistics correlate
directly with the tissue's mechanical properties, described by an energy functional with …

The aim of this review is to provide a concise overview of some of the generic approaches
that have been developed to deal with the statistical description of large systems of …

Assemblies of anisotropic particles commonly appear in studies of active many-body
systems. However, in two dimensions, the geometric ramifications of the finite density of …

Pseudo-two-dimensional (2D) foams are commonly used in foam studies as it is
experimentally easier to measure the bubble size distribution and other geometric and …
