Query: Faceting and flattening of emulsion droplets: a mechanical model   When cooled down, emulsion droplets stabilized by a frozen interface of
alkane molecules and surfactants have been observed to undergo a spectacular
sequence of morphological transformations: from spheres to faceted icosahedra,
down to flattened liquid platelets. While generally ascribed to the interplay
between the elasticity of the frozen interface and surface tension, the
physical mechanisms underpinning these transitions have remained elusive,
despite different theoretical pictures having been proposed in recent years. In
this article, we introduce a comprehensive mechanical model of morphing
emulsion droplets, which quantitatively accounts for various experimental
observations, including the scaling behavior of the faceting transition. Our
analysis highlights the role of gravity and the spontaneous curvature of the
frozen interface in determining the specific transition pathway.
