Interplay between spherical confinement and particle shape on the self-assembly of rounded cubes

The authors study the self-assembly of sharp and rounded nanocubes under spherical confinement, revealing the influence of particle and face geometry on positional and orientational behavior.

Shape-sensitive crystallization in colloidal superball fluids

It is shown that colloidal silica superballs crystallize into canted phases in the presence of depletants, a general scenario where particle building blocks are designed to assemble not only into their maximum density states, but also into depletion-tunable interaction-dependent structures.

Synthesis of Light‐Diffracting Assemblies from Microspheres and Nanoparticles in Droplets on a Superhydrophobic Surface

Self-assembly of colloidal particles into crystalline arrays can be an effective tool for fabricating novel materials with advanced functionality. The periodicity at the micrometer and sub-micrometer

Anisotropic particle synthesis inside droplet templates on superhydrophobic surfaces.

We demonstrate how droplet templates dispensed on superhydrophobic substrates can be used to fabricate both shape-anisotropic ("doughnut") and composition-anisotropic ("patchy magnetic")

Observation of solid–solid transitions in 3D crystals of colloidal superballs

The experimental phase behaviour of superball particles with a shape in between that of a sphere and a cube is presented, and it is uncovered that the phase behaviour is richer than predicted, as two distinct rhombohedral crystals with different stacking variants, namely hollow-site and bridge-site stacking.

Entropy-driven formation of large icosahedral colloidal clusters by spherical confinement.

It is reported that entropy and spherical confinement suffice for the formation of icosahedral clusters consisting of up to 100,000 particles that are entropically favoured over the bulk face-centred cubic crystal structure.

Color from hierarchy: Diverse optical properties of micron-sized spherical colloidal assemblies

The control of multiple optical effects induced by the hierarchical morphology in photonic balls paves the way to use them as building blocks for complex optical assemblies—potentially as more efficient mimics of structural color as it occurs in nature.

Phase diagram of colloidal hard superballs: from cubes via spheres to octahedra

For hard anisotropic particles the formation of a wide variety of fascinating crystal and liquid-crystal phases is accomplished by entropy alone. A better understanding of these entropy-driven phase

Total synthesis of colloidal matter

Atoms serve as an inspiration for colloidal self-assembly, whereby building blocks can combine and confer endless functionality using a few design principles, including directionality, valence and

Predictive Self-Assembly of Polyhedra into Complex Structures

145 convex polyhedra whose assembly arises solely from their anisotropic shape are investigated, demonstrating a remarkably high propensity for thermodynamic self-assembly and structural diversity.
