From these newly shaped particles, a second generation of anisotropic and shape-complementary colloids is obtained by selectively dissolving one polymer or the other. In particular, the polymerized TPM part is recovered by washing the particles in toluene whereas the PS is isolated by washing the TPM oil off in … Visa mer Our method comprises three main steps in which biphasic colloids are first synthesized and then reshaped by surface tension during a series of consecutive phase transformations. In the first step, which we refer to as … Visa mer If, instead of polymerizing the oil phase, we liquify the solid PS phase by allowing the seeds to absorb a small amount of toluene, an entirely new family of particle shapes can be … Visa mer The different nature of our bi-material particles also opens new avenues to fabricating Janus or patchy colloids in bulk amounts. Silane … Visa mer By varying the experimental conditions during the nucleation step (see Methods section), multiple oil droplets can be controllably grown on the same seed to yield dumbbells or particles with multiple protrusions. As … Visa mer WebbOur method is based on a controlled deformation of multiphase colloidal particles that can be selectively liquified, polymerized, dissolved and functionalized in bulk. We further …
Design strategies for the self-assembly of polyhedral shells
WebbHere, we investigate in detail the problem of the self-assembly of the three Archimedean shells with five contact points per vertex, i.e., the icosahedron, the snub cube, and the snub dodecahedron. We use patchy particles with five interaction sites (or patches) as model for the building blocks and recast the assembly problem as a Boolean ...
