Self-assembly scenarios of patchy colloidal particles in two dimensions.
We have investigated the self-assembly scenario of patchy colloidal particles in a two-dimensional system. The energetically most favourable ordered particle arrangements have been identified via an optimization tool that is based on genetic algorithms. Assuming different simple models for patchy colloidal particles, which include binary mixtures as well as attraction and repulsion between the ...
متن کاملSelf-Assembly of Patchy Particles.
Molecular simulations are performed to study the self-assembly of particles with discrete, attractive interaction sites - "patches" - at prescribed locations on the particle surface. Chains, sheets, rings, icosahedra, square pyramids, tetrahedra, and twisted and staircase structures are obtained through suitable design of the surface pattern of patches. Our simulations predict that the spontane...
متن کاملSurface roughness directed self-assembly of patchy particles into colloidal micelles.
Colloidal particles with site-specific directional interactions, so called "patchy particles", are promising candidates for bottom-up assembly routes towards complex structures with rationally designed properties. Here we present an experimental realization of patchy colloidal particles based on material independent depletion interaction and surface roughness. Curved, smooth patches on rough co...
متن کاملColloidal self-assembly: Patchy from the bottom up.
So, even if this phase-change material shows Anderson localization, can electron correlations still play a role? Not particularly, as in GeSb2Te4 these correlations are small and do rule out a Mott transition1. In the Mott picture, crystalline GeSb2Te4 should always be metallic. Yet it is not. Rather, Siegrist and colleagues derive a minimum metallic conductivity whose value agrees well with Mo...
متن کاملSelf-Assembly of Polyhedral Hybrid Colloidal Particles
We have developed a new method to produce hybrid particles with polyhedral shapes in very high yield (liter quantities at up to 70% purity) using a combination of emulsion polymerization and inorganic surface chemistry. The procedure has been generalized to create complex geometries, including hybrid line segments, triangles, tetrahedra, octahedra, and more. The optical properties of these part...
