Tuning Patchy Bonds Induced by Critical Casimir Forces
WebApr 22, 2024 · We have shown that patchy colloidal fluid with three and four equivalent patches, confined in the attractive random porous media, undergoes the re-entrant gas–liquid phase separation, with the possibility for the liquid phase to have vanishing low density. This behavior is caused by an interplay between the strong colloid–colloid … Patchy particles are micron- or nanoscale colloidal particles that are anisotropically patterned, either by modification of the particle surface chemistry ("enthalpic patches"), through particle shape ("entropic patches"), or both. The particles have a repulsive core and highly interactive … See more Simulations The interaction between patchy particles can be described by a combination of two discontinuous potentials. A hard sphere potential accounting for the repulsion between the cores … See more • Self-assembly • Janus particles • Entropic force See more • Amar B.

Web2 days ago · We propose a second-order thermodynamic perturbation theory for a hard-sphere patchy colloidal model with two doubly bondable patches of type A and B. AB bonding results in the formation of a ... WebHere, 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 ... WebDec 10, 2024 · During the past decade, there has been a hot debate about the physical mechanisms that determine when a colloidal dispersion approaches the gel transition. However, there is still no consensus on a possible unique route that leads to the conditions for the formation of a gel-like state. Based on gel states identified in experiments, … unthan thayaval naan lyrics
