Self-assembly of anisotropic colloidal building blocks via critical Casimir forces (B07)

该项目利用曲率依赖的临界Casimir力进行长距离粒子相互作用，使其自组装。首先，将深入研究吸引性椭圆粒子的结晶。第一个实验表明曲率依赖的临界卡西米尔力的特别重要性，这方面既没有实验，也没有理论解决到目前为止。第二，将使用最近开发的计划，它采用了一个活跃的探针粒子，其旋转扩散系数是相当敏感的环境的结构特性的悬浮液的硬二氧化硅棒的机械性能进行测量。

This project utilizes curvature dependent critical Casimir forces for long range particle interactions towards their self-assembly. First, the crystallization of attractive elliptical particles will be studied in-depth. First experiments indicated the particular importance of curvature-dependent critical Casimir forces, an aspect which has neither been experimentally nor theoretically addressed so far. Second, the mechanical properties of suspensions of hard silica rods will be measured using a recently developed scheme, which employs an active probe particle whose rotational diffusion coefficient is rather sensitive to the structural properties of the environment.
