Orientational microrheology (B05)

示踪粒子的运动提供了对复杂物质局部性质的洞察，具有非凡的空间和时间分辨率，使用定制的核壳胶体探针结合光学镊子，并结合分子动力学模拟。在第一个资助期发现的导致液态玻璃形成的机制，它在相空间中的区域，以及它的机械和运输性质将通过实验和理论来确定。这包括发展对椭圆形颗粒施加外力矩和外力的实验装置，研究液态玻璃稳定性的极限，以及确定颗粒在原地和外部驱动下运动的理论发展。这也将延伸到纳米颗粒的组装上。

The motion of tracer particles provides insights into the local properties of complex matter with exceptional spatial and temporal resolution using tailor-made core-shell colloidal probes together with optical tweezing, and combined with molecular dynamics simulations. The mechanisms leading to the formation of liquid glass discovered in the first funding period, its region in phase space, and its mechanical and transport properties will be determined experimentally and by theory. This includes the development of experimental set-ups to apply external torques and forces onto the ellipsoidal particles, to investigate the limits of stability of liquid glass and theoretical developments to determine the particle motions in situ and under external driving. This will also extend to assemblies of nanoparticles.
