Query: Electrical conductivity of quasi-two-dimensional foams   Quasi-two-dimensional (quasi-2D) foams consist of monolayers of bubbles
squeezed between two narrowly spaced plates. These simplified foams have served
successfully in the past to shed light on numerous issues in foam physics. Here
we consider the electrical conductivity of such model foams. We compare
experiments to a model which we propose, and which successfully relates the
structural and the conductive properties of the foam over the full range of the
investigated liquid content. We show in particular that in the case of quasi-2D
foams the liquid in the nodes needs to be taken into account even at low liquid
content. We think that these results may provide different approaches for the
characterization of foam properties and for the in situ characterization of the
liquid content of foams in confining geometries, such as microfluidics
