SUSTech’s Zuowei XIE wins Humboldt Research Award


Zuowei XIE, Chair Professor of the Department of Chemistry at the Southern University of Science and Technology (SUSTech) and Academician of the Chinese Academy of Sciences (CAS), was recently awarded the 2022 Humboldt Research Award by the Alexander von Humboldt Foundation of Germany.

“Big Bang” of 2D-vdW Ferroelectrics


A century has passed since the discovery of ferroelectricity in Rochelle salt. Since then, we have learned a great deal about the fascinating physics of ferroelectric materials. Based on the functionalities and switchable polarization that arise from them, we have developed a host of practical devices, such as ferroelectric random-access memory, actuators, transducers, infrared detectors, and electro-optic modulators.

Scientists realize ultralow-loss and high-fidelity interconnects for modular superconducting quantum processors


In recent years, superconducting quantum computing has developed rapidly with the potential to scale to thousands of qubits in the next few years and explore practical applications of Noisy Intermediate-Scale Quantum (NISQ) devices based on this. However, superconducting qubits have large sizes, and each qubit requires dedicated RF-control lines, making it increasingly challenging to integrate more qubits on a single chip as the number of qubits increases. Modularity offers a viable approach for scaling up to large numbers of qubits in the near term; however, this relies on very high-performance interconnects between the computing modules.

Advances in space dust impact detection


Interstellar space has numerous micro-scale dust. On the one hand, space dust is a potential threat to spacecraft; on the other hand, it plays a significant role in stellar evolution.

Researchers make breakthrough in asymmetric radical heteroatomic S–O cross-coupling


The transition-metal-catalysed cross-coupling reaction between an organo(pseudo)halide and a nucleophile is important in organic synthesis for carbon-carbon (C–C) and carbon-heteroatom (C–E, where E indicates p-block elements other than carbon) bond formations, in both industrial and academic settings (Fig. 1a).

Researchers make progress in spin polarization of antiferromagnets


Spin polarization is the basic concept of spintronics. In the last decade, the spin-orbital coupling effect in noncentrosymmetric crystal material-induced spin-momentum locking polarization, such as the Rashba effect, has promoted the development of a new generation of spintronics devices. While in the class of centrosymmetric material, the spin-orbital coupling effect cooperating with the local inversion symmetry breaking also induced the odd-spatially distributed spin polarization, named “Hidden Spin Polarization”, which has promised an expanded material pool for future spintronics. However, such an exotic hidden effect is difficult to be detected and thus be utilized for a device.
