PolyU PhD Thesis Award 2023-1

AP graduating PhD students received the PolyU PhD Thesis Award for Merit

To recognize, honor, and promote the outstanding research accomplishments of graduating PhD students, the Graduate School establishes the PhD Thesis Award with two award classes: Outstanding and Merit.   Congratulations to Dr HOU Zhen on receiving the PolyU PhD Thesis Award for Merit. His thesis focuses on understanding Zn nucleation and growth towards stable Zn metal batteries.  Thesis Title: Boosting zinc metal anodes performance via interface engineering: reaction kinetics, morphology control and electrochemical reversibility Chief Supervisor: Dr ZHANG Biao The thesis is devoted to reversible Zn metal anodes through regulating the Zn nucleation and growth. We first demonstrate that the slow desolvation kinetics elevates the nucleation overpotential for improving the nucleation sites through introducing acetonitrile co-solvent into the electrolyte. The electrolyte recipe is further tailored to produce abundant Zn nucleation seeds and smooth Zn growth. The designed oligomer co-solvent enables preferential surface adsorption and the optimized solvation sheath. Furthermore, we propose a facile pulsed cycling protocol where an initial high current density (J) is leveraged to form sufficient nuclei for guiding even metal deposition at standard J in the subsequent process, realizing high-performance Zn, Li and K metal batteries. Besides modulating the Zn nucleation, we also control the Zn growth process by constructing a metallic tin-coated separator. Specifically, its decent electrical conductivity and zincophilicity can eliminate the inevitably formed Zn dendrites via face-to-face Zn growth, thus enabling improved cycle life even at high J and cycling capacity.

Leng Award-Winning-1

Dr Kathy LENG awarded the Nation’s Excellent Young Scientists Fund

The National Natural Science Foundation of China (NSFC), under the Ministry of Science and Technology, has honored Dr. Kathy K. Leng, an Assistant Professor in the Department of Applied Physics, with the prestigious Excellent Young Scientists Fund (Hong Kong and Macao) for the year 2023. Her awarded research project “Molecularly Thin 2D Hybrid Perovskite and Innovative Devices” studied molecularly thin 2D hybrid perovskites, a new class of 2D materials with the characteristics of high structural flexibility and interesting optoelectronic properties. The ability to tune the responses of such materials by external stimuli enables applications in intelligent and functional devices. They also serve as new platforms for fundamental physics studies. Dr. Leng will continue her research on the large-scale growth and device applications of these materials.   Ta Kung Pao: Wen Wei Po:

Prof Feng Yan Interviewed by Nature Portfolio

Prof Feng YAN was interviewed by Nature Portfolio

Prof. Feng YAN, ADoRI-IWEAR & Chair Professor of Organic Electronics, heads a research group that specializes in advanced materials, including organic semiconductors and perovskite materials. His research includes the development of field-effect transistors and ultra-high-sensitivity biosensors, which have made significant global impacts. Yan and his team have also demonstrated that two-dimensional conjugated metal organic frameworks are excellent semiconductor materials for high-performance electrochemical transistors (ECTs). These ECTs have promising applications in flexible and wearable electronics, as well as in bioelectronics and neuromorphic devices. In addition, Yan's team is exploring the use of perovskites as an alternative to silicon-based solar cells, and has made significant breakthroughs that improve the efficiency and stability of perovskite solar cells in an ambient atmosphere. Yan's leadership in advanced materials is a prime example of PolyU AP's scientific focus on contributing to society.   Article in Nature Portfolio:

Prof Chai Optoelectronic graded sensor

Prof. Yang CHAI develops optoelectronic graded neurons for perceiving dynamic motion

Leading a research team, Prof. Yang CHAI, Associate Dean of the Faculty of Science and Professor in the Department of Applied Physics, developed optoelectronic graded neurons for recognizing and perceiving dynamic motion agilely with limited hardware resources. This advanced machine vision system can perform high information transmission rate and fuse spatial and temporal information at sensory terminal while the conventional sensors can only output “spatial” frames without fusing “temporal” information. Compared to recognition performed with traditional image sensors (~50%), the accuracy of action recognition approaches 99.2%.   To learn more:
