Structure formation in confined colloidal rod-sphere mixtures (B04)

该项目旨在实现对第二组胶体的形状和“掺杂”如何在几何约束和外场下控制各向异性胶体的相行为的基本理解。它结合了单层和薄膜的实验/理论研究，i)一组具有定制形状的各向异性胶体，ii)各向异性和各向同性胶体的二元混合物。各向异性纳米颗粒在空气-水界面阵列的研究将继续进行，离心场辅助各向异性胶体的组装将成为一个新的重点。通过计算机模拟对各向异性粒子（哑铃、球柱）和各向同性粒子混合物系统的研究将继续和扩展。

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.
