Polyhedra and their arrangements have intrigued humankind since the ancient Greeks and are today important motifs in condensed matter, with application to many classes of liquids and solids. Yet, little is known about the thermodynamically stable phases of polyhedrally shaped building blocks, such as faceted nanoparticles and colloids. Although hard particles are known to organize due to entropy alone, and some unusual phases are reported in the literature, the role of entropic forces in…

Classifying Crystals of Rounded Tetrahedra and Determining Their Order Parameters Using Dimensionality Reduction

It is argued that these characteristic combinations of q̅l are also useful as reliable order parameters in nucleation studies, enhanced sampling techniques, or inverse-design methods involving odd-shaped particles in general.

Structural diversity and the role of particle shape and dense fluid behavior in assemblies of hard polyhedra

A fundamental characteristic of matter is its ability to form ordered structures under the right thermodynamic conditions. Predicting these structures - and their properties - from the attributes of

Complexity in surfaces of densest packings for families of polyhedra

Packings of hard polyhedra have been studied for centuries due to their mathematical aesthetic and more recently for their applications in fields such as nanoscience, granular and colloidal matter,

Intermediate crystalline structures of colloids in shape space.

The resulting landscapes show, as a function of shape, regions where ordered structures assemble, what is assembled and at what density, locations of transitions between regions of ordered structures, and regions of disorder.

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.

Polyhedron packings have fascinated humans for centuries and continue to inspire scientists of modern disciplines. Despite extensive computer simulations and a handful of experimental investigations,

Clusters of polyhedra in spherical confinement

This work uses computational methods to determine dense packings of a set of polyhedra inside a sphere, for up to 60 constituent packers, and investigates the interplay between anisotropic particle shape and isotropic 3D confinement.

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

Entropic self-assembly of freely rotating polyhedral particles confined to a flat interface.

A first-order analysis of the particle-surface energies associated with a fluid-fluid interface indicates that such enthalpic interactions will be particularly important in determining particle orientation behavior at low to intermediate concentrations.

Dense crystalline packings of ellipsoids.

The discovery of the SQ-TR crystal suggests organizing principles for nonspherical particles and self-assembly of colloidal systems, and a phase diagram for self-dual ellipsoids is reported.



Self-assembly of uniform polyhedral silver nanocrystals into densest packings and exotic superlattices.

It is shown with experiment and computer simulation that a range of nanoscale Ag polyhedra can self-assemble into their conjectured densest packings, and that octahedra form an exotic superstructure with complex helical motifs rather than the densest Minkowski lattice.

Communication: a packing of truncated tetrahedra that nearly fills all of space and its melting properties.

This work analytically construct the densest known packing of truncated tetrahedra with a remarkably high packing fraction φ = 207/208 = 0.995192, which is amazingly close to unity and strongly implies its optimality.

Disordered, quasicrystalline and crystalline phases of densely packed tetrahedra

The first example of a quasicrystal formed from hard or non-spherical particles, which can be compressed to a packing fraction of φ = 0.8324, is reported, demonstrating that particle shape and entropy can produce highly complex, ordered structures.

Low packing density self-assembled superstructure of octahedral Pt3Ni nanocrystals.

It is found that this arrangement of a bcc superstructure with nanoctahedra connecting through their vertices is dependent on neither the processing pathway nor the substrate under the authors' experimental conditions.

A method for discovering dense packings of general convex hard particles is presented and applied to study the dense packing behavior of a one-parameter family of particles with tetrahedral symmetry, uncovering a rich optimal-packing behavior, compared to that of other continuous families of particles previously studied.

Mesophase behaviour of polyhedral particles.

It is found that dynamical disorder is crucial in defining mesophase behaviour, and that the apparent kinetic barrier for the liquid-mesophase transition is much lower for liquid crystals (orientational order) than for plastic solids (translational order).

Dense Crystalline Dimer Packings of Regular Tetrahedra

The packing is crystalline with a unit cell of four tetrahedra forming two triangular dipyramids (dimer clusters) and it is shown that the packing has maximal density within a three-parameter family of dimer packings.

Formation of orientation-ordered superlattices of magnetite magnetic nanocrystals from shape-segregated self-assemblies.

Transmission electron microscopy analysis indicates that the faceted nanocrystal mixture tends to self-segregate based upon the shape in a self-assembly process, and each shape forms its own distinct crystallographic orientation-ordered superlattice assemblies.

Structural diversity in binary nanoparticle superlattices

It is demonstrated that electrical charges on sterically stabilized nanoparticles determine B NSL stoichiometry; additional contributions from entropic, van der Waals, steric and dipolar forces stabilize the variety of BNSL structures.

Self-Assembly of Patchy Particles.

The results show how precise arrangements of patches combined with patch "recognition" or selectivity may be used to control the relative position of particles and the overall structure of particle assemblies.
