In its past years of funding within the Emmy Noether programme, the research project was very successful. The research on active colloidal particles and suspensions of active colloidal particles including active colloidal liquid crystals, how their dynamics is affected by external fields, and how such fields can be used to control their dynamics, has already resulted in several publications, comprising articles and software, as well as a patent application. Some publications appeared in high-impact journals and resulted in large press coverage. A few of our results open up important new directions of research that should be further pursued by separate projects in the future. These new directions include the investigation of colloidal particles with orientation-dependent motility.This writing proposes an additional subproject for a 6th year of funding that aims at pursuing one of the new directions of research that arose during the previous research on the original project. In the 6th year of funding, active colloidal liquid crystals with orientation-dependent motility shall be investigated. The new subproject aims at studying the collective dynamics of active colloidal liquid crystals and mixtures of different types of active colloidal liquid crystals with an orientation-dependent motility, the effect of external fields on their collective dynamics, and how such fields can be used to control the dynamics. The research will be performed by applying analytical methods of theoretical physics as well as computer simulations.

在过去几年的艾美奖诺特计划的资助下，该研究项目非常成功。对活性胶体颗粒和活性胶体颗粒的悬浮液（包括活性胶体液晶）、它们的动力学如何受外部场影响以及这些场如何可用于控制它们的动力学的研究已经产生了若干出版物，包括文章和软件，以及专利申请。一些出版物发表在影响力大的期刊上，引起了媒体的广泛报道。我们的一些结果开辟了重要的新的研究方向，应在未来的单独项目进一步追求。这些新的方向包括调查的胶体粒子与方向依赖motility.This写作提出了一个额外的子项目的第6年的资金，旨在追求的新的研究方向，在以前的研究中出现的原项目。在第6年的资助，应研究具有取向依赖运动性的活性胶体液晶。新的子项目旨在研究活性胶体液晶的集体动力学和具有取向依赖运动性的不同类型的活性胶体液晶的混合物，外部场对其集体动力学的影响，以及如何使用这些场来控制动力学。该研究将通过应用理论物理分析方法以及计算机模拟来进行。
