Viscoelasticity reshapes the frequency response of a rotating magnetic particle
Zhiyuan Zhao, Tingting Sun, Han Gao +3
A magnetic particle driven by a rotating magnetic field undergoes a transition from synchronous to asynchronous rotation at a critical driving frequency. The asynchronous dynamics…

Response of magnetic particle to rotating magnetic field in viscoelastic fluid
Han Gao, Zhiyuan Zhao, Masao Doi +1
The rotational dynamics of a freely suspended ferromagnetic particle in viscoelastic fluid subjected to a rotating magnetic field is studied by experiments and theory. Our result r…

Dehydration drives damage in the freezing of brittle hydrogels
Shaohua Yang, Dominic Gerber, Yanxia Feng +6
It is widely known that freezing breaks soft, wet materials. However, the mechanism underlying this damage is still not clear. To understand this process, we freeze model, brittle…
