CUHK Physicists Discover New Route to Active Matter Self-Organisation Provides New Directions on Fabricating Self-driven Devices and Microbial Physiology
An international team led by Professor Yilin Wu, Associate Professor of the Department of Physics at The Chinese University of Hong Kong (CUHK) has made a novel conceptual advance in the field of active matter science. The team discovered a new route in which the self-organisation of active fluids in space and time can be controlled by a single material property called viscoelasticity. This new finding may pave the way for fabricating a new class of self-driven devices and materials, such as the ability to control the rhythmic movement of soft robots without relying on electronic circuits, and for the study of microbial physiology. It has been published in the scientific journal Nature.

Researchers at Pohang University of Science and Technology (POSTECH) and Seoul National University in South Korea have demonstrated a new way to enhance the energy efficiency of a non-volatile magnetic memory device called SOT-MRAM. Published in
Advanced Materials, this finding opens up a new window of exciting opportunities for future energy-efficient magnetic memories based on spintronics.
In modern computers, the random access memory (RAM) is used to store information. The SOT-MRAM (spin-orbit torque magnetic RAM) is one of the leading candidates for the next-generation memory technologies that aim to surpass the performance of various existing RAMs. The SOT-MRAM may operate faster than the fastest existing RA
