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, … WebPatchy models consider particles as hard or soft spheres carrying a finite and small number of attractive sites arranged in precise geometries on the particle's surface. The anisotropy of the interaction and the limited valence in bonding are the salient features determining the collective behavior of such systems.
WebJun 29, 2024 · Valency, or patchiness, refers to the number and spatial distribution of interacting domains (Fig. 1A). When attractive patches are present, the number of ways two interacting components can be positioned relative to one another will be limited. WebPatchy colloids of different shapes, patterns and functionalities are considered the new building blocks of a bottom-up approach toward the realization of self-assembled bulk materials with predefined properties. ...
