Phase diagram of patchy colloids: towards empty liquids.
We report theoretical and numerical evaluations of the phase diagram for patchy colloidal particles of new generation. We show that the reduction of the number of bonded nearest neighbors offers the possibility of generating liquid states (i.e., states with temperature T lower than the liquid-gas critical temperature) with a vanishing occupied packing fraction (phi), a case which can not be rea...
متن کاملLiquid-vapor interfaces of patchy colloids.
We investigate the liquid-vapor interface of a model of patchy colloids. This model consists of hard spheres decorated with short-ranged attractive sites ("patches") of different types on their surfaces. We focus on a one-component fluid with two patches of type A and nine patches of type B (2A9B colloids), which has been found to exhibit reentrant liquid-vapor coexistence curves and very low-d...
متن کاملCrystallization of tetrahedral patchy particles in silico.
We investigate the competition between glass formation and crystallization of open tetrahedral structures for particles with tetrahedral patchy interactions. We analyze the outcome of such competition as a function of the potential parameters. Specifically, we focus on the separate roles played by the interaction range and the angular width of the patches, and show that open crystal structures ...
متن کاملPatchy colloids: entropy stabilizes open crystals.
S purred by recent advances in microparticle synthesis, colloidal particles with 'sticky patches' on their surface have of late become a focus of interest. This is in great part because colloids with anisotropic, patchy interactions should allow better control of colloidal self-assembly so as to achieve specific target structures with tailored photonic, catalytic or mechanical properties 1. Man...
متن کاملGeneralized Onsager theory for strongly anisometric patchy colloids.
The implications of soft "patchy" interactions on the orientational disorder-order transition of strongly elongated colloidal rods and flat disks is studied within a simple Onsager-van der Waals density functional theory. The theory provides a generic framework for studying the liquid crystal phase behaviour of highly anisometric cylindrical colloids which carry a distinct geometrical pattern o...
