Generalized 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...
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 کاملBiaxial mesophase behavior of amphiphilic anisometric colloids: a simulation study.
The phase behavior of amphiphilic anisometric particles is explored using Monte Carlo simulations. The particles are composed of two incompatible laterally attached units: a spherocylinder and a spheroplatelet. A liquid crystalline phase polymorphism is obtained including biaxial nematic, (quasi long range biaxial) calamitic smectic-A, biaxial lamellar and columnar phases. The simulation result...
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 کاملVelocity Gradient Power Functional Theory for Brownian Dynamics,Liquid-vapour Interfaces of Patchy Colloids
functional theory to nonequilibrium Brownian dynamics. We present an explicit and simple approximation for the superadiabatic excess (over ideal gas) power functional based on the local velocity gradient. The resulting superadiabatic forces, obtained via functional differentiation, are beyond dynamical density functional theory and explain a broad range of phenomena such as viscous forces, lane...
