Ultra-Soft Colloids in Shear Flow

Vesicles and droplets encompass fluid which is not exchanged with the surrounding. In contrast, for star-like molecules fluid is free to penetrate into the molecule and internal fluid is exchanged with the surrounding in the course of time. This intimate coupling of the star-polymer dynamics and the fluid flow leads to a strong modification of the flow behavior at and next to the ultrasoft coUoid particularly in non-equilibrium systems. 

The fluid flow in the vicinity of the star polymer is distinctively different from that of a sphere but resembles the flow around an ellipsoid [144]. In contrast to 

A convenient quantity to characterize the structural properties and aligmnent of polymers in flow is the average gyration tensor, which is defined as 

The data for the average orientation and deformation of a star polymer described so far seem to indicate that the properties vary smoothly and monotonically from lin- 

The rotational dynamics of a star polymer can be characterized quantitatively by calculating the rotation frequency
