Query: Arresting bubble coarsening: A two-bubble experiment to investigate
  grain growth in presence of surface elasticity   Many two-phase materials suffer from grain-growth due to the energy cost
which is associated with the interface that separates both phases. While our
understanding of the driving forces and the dynamics of grain growth in
different materials is well advanced by now, current research efforts address
the question of how this process may be slowed down, or, ideally, arrested. We
use a model system of two bubbles to explore how the presence of a finite
surface elasticity may interfere with the coarsening process and the final
grain size distribution. Combining experiments and modelling in the analysis of
the evolution of two bubbles, we show that clear relationships can be predicted
between the surface tension, the surface elasticity and the initial/final size
ratio of the bubbles. We rationalise these relationships by the introduction of
a modified Gibbs criterion. Besides their general interest, the present results
have direct implications for our understanding of foam stability.
