TLDR
In this article, the collective behavior of a close-packed monolayer of non-Brownian particles at a fluid-liquid interface was studied and Young's modulus and Poisson ratio was derived from simple theoretical considerations.Abstract:
We study the collective behaviour of a close-packed monolayer of non-Brownian particles at a fluid-liquid interface. Such a particle raft forms a two-dimensional elastic solid and can support anisotropic stresses and strains, e.g. it buckles in uniaxial compression and cracks in tension. We characterise this solid in terms of Young's modulus and Poisson ratio derived from simple theoretical considerations and show the validity of these estimates by using an experimental buckling assay to deduce Young's modulus.read more

TL;DR: This work provides insight into the interfacial stability of such diverse systems as biological membranes such as lung surfactant and nanoparticle thin films and general scaling laws for the wrinkled and folded states.

Bicontinuous emulsions stabilized solely by colloidal particles.
TL;DR: A reproducible protocol for creating three-dimensional samples of bijel in which the interfaces are stabilized by essentially a single layer of particles, and it is demonstrated how to tune the mean interfacial separation in these bijels, and that mechanically, they indeed behave as soft solids.

Solid-stabilized emulsions
TL;DR: In this article, the comprehension of bulk properties of solid-stabilized emulsions (stability, compressibility, elasticity) in relation with interfacial properties has progressed.

Colloid science: non-spherical bubbles.
TL;DR: It is shown that gas bubbles and liquid drops can exist in stable, non-spherical shapes if the surface is covered, or ‘armoured’, with a close-packed monolayer of particles.
