This project aims to achieve a fundamental understanding how shape and “doping” with a second set of colloids governs phase behaviour of anisotropic colloids also under geometric confinement and external fields. It joins experimental/theoretical studies of monolayers and thin films from i) a single set of anisotropic colloids with custom-tailored shapes, and ii) binary mixtures of anisotropic and isotropic colloids. The work on arrays of anisotropic nanoparticles at the air-water interface will be continued and assembly of anisotropic colloids assisted by centrifugal fields will become a new priority. Investigations of systems with anisotropic particles (dumbbells, spherocylinders) as well as mixtures with isotropic particles by computer simulations will be continued and extended.

该项目旨在实现一个基本的理解，即形状和第二组胶体的“掺杂”如何控制几何约束和外场下各向异性胶体的相行为。它结合了对单层和薄膜的实验/理论研究，从i)具有定制形状的单组各向异性胶体，以及ii)各向异性胶体和各向同性胶体的二元混合物。空气-水界面各向异性纳米粒子阵列的工作将继续下去，离心场辅助的各向异性胶体组装将成为新的优先事项。通过计算机模拟对各向异性粒子(哑铃、球柱)以及具有各向同性粒子的混合物的系统的研究将继续和扩展。
