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.

该项目旨在实现基本的理解，其中第二组胶体如何在几何限制和外部田地下如何控制各向异性胶体的相位行为。它与I）一组具有定制形状的各向异性胶体的单层和薄膜的实验/理论研究以及ii）二进制混合物的各向异性和各向同性胶体的混合物。在空气水接口处各向异性纳米颗粒阵列的工作将继续，并且由离心场辅助的各向异性胶体组装将成为一个新的优先事项。通过计算机模拟对具有各向异性颗粒（哑铃，球形固定器）以及与各向同性颗粒的混合物的系统进行研究。
