Colloidal particles or nanoparticles, with equal affinity for two fluids, are known to adsorb irreversibly to the fluid-fluid interface. We present large-scale computer simulations of the demixing of a binary solvent containing such particles. The newly formed interface sequesters the colloidal particles; as the interface coarsens, the particles are forced into close contact by interfacial tension. Coarsening is markedly curtailed, and the jammed colloidal layer seemingly enters a glassy state… 
A continuum model of colloid-stabilized interfaces
Colloids that are partially wetted by two immiscible fluids can become confined to fluid-fluidinterfaces. At sufficiently high volume fractions, the colloids may jam and the interface may
Bijels containing magnetic particles: a simulation study.
Here, lattice Boltzmann simulation is explored the possible effects of using magnetic colloids in bijels to allow additional control over the structure, during or after formation, by application of a magnetic field or field gradient.
Disordered interfaces in soft fluids with suspended colloids
Computer simulations of bi-continuous two-phase fluids with interspersed dumbbells show that, unlike rigid colloids, soft dumbbells do not lead to arrested coarsening. However, they significantly
Bijels: a new class of soft materials
Bicontinuous interfacially jammed emulsion gels (‘bijels’) were proposed in 2005 as a hypothetical new class of soft materials in which interpenetrating, continuous domains of two immiscible fluids
Bijels stabilized using rod-like particles.
It is shown for the first time the use of rod-shape particles to stabilize bijels and that domain size decreases more rapidly with particle concentration in the case of rods compared to spheres.
Chains of cubic colloids at fluid-fluid interfaces.
This work theoretically investigates whether capillary interactions can be responsible for spontaneous chain formation of cubic particles adsorbed at a fluid-fluid interface and identifies several regimes with stable chainlike structures in line with the experimental observations.

The development of one example: colloid-stabilized emulsions with bicontinuous liquid domains, which resemble the sponge mesophase of surfactants, is reviewed.
Bicontinuous emulsions stabilized solely by colloidal particles.
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.


Cellular solid behaviour of liquid crystal colloids 1. Phase separation and morphology
Abstract:We study the phase ordering colloids suspended in a thermotropic nematic liquid crystal below the clearing point and the resulting aggregated structure. Small () PMMA particles are dispersed
Colloidosomes: Selectively Permeable Capsules Composed of Colloidal Particles
An approach to fabricate solid capsules with precise control of size, permeability, mechanical strength, and compatibility is presented, which are hollow, elastic shells whose permeability and elasticity can be precisely controlled.
Forming supramolecular networks from nanoscale rods in binary, phase-separating mixtures
Simulations show that when low-volume fractions of nanoscale rods are immersed in a binary, phase-separating blend, the rods self-assemble into needle-like, percolating networks, which provide a means of manipulating the motion of nanoscopic objects and directing their association into supramolecular structures.
Wetting-Induced Aggregation of Colloids
More than two decades ago, in a seminal paper John Cahn proposed scaling arguments for the possibility of a wetting transition in two coexisting fluid phases near the critical point. Since then,
Novel Colloidal Interactions in Anisotropic Fluids
Small water droplets dispersed in a nematic liquid crystal exhibit a novel class of colloidal interactions, arising from the orientational elastic energy of the anisotropic host fluid, which can lead to novel mechanisms for colloid stabilization.

Dense Packing and Symmetry in Small Clusters of Microspheres
The emulsion system presents a route to produce new colloidal structures and a means to study how different physical constraints affect symmetry in small parcels of matter.
Multiple Glassy States in a Simple Model System
Experiments, theory, and simulation were used to study glass formation in a simple model system composed of hard spheres with short-range attraction (“sticky hard spheres”) and revealed a reentrant glass transition line.

We have studied the kinetics of phase separation in a colloid-polymer mixture. The evolution of initially homogeneous samples as they separate into coexisting colloidal gas, liquid, and crystal
