Insightful study published in renowned journal Addressing ozone pollution challenges with synergistic control

An international research team led by PolyU scholars has published a ground-breaking perspective article in the prestigious journal One Earth. The study focuses on combating ground-level ozone pollution, a pressing environmental issue affecting human health, crop yields, and global climate change. The team, comprising 30 scholars from 10 countries, proposes a synergistic control approach between ozone and climate to address the challenges of rising tropospheric ozone levels. Prof. GUO Hai and Prof. WANG Tao from the Research Institute for Sustainable Urban Development (RISUD) are one of the corresponding authors and co-authors, respectively. The research highlights the alarming increase in warm-season ozone pollution over the past decade. Key regions, including Mainland China, the United States, and Europe, have experienced significant ozone rises, posing challenges in pollution control due to changing emissions and the influence of climate warming. The study emphasises the need for a comprehensive strategy that integrates ozone and climate control, prioritising both human and ecosystem health. By connecting emissions, mechanisms and policies, this approach offers a remarkable solution to mitigate ozone pollution while fostering international collaboration for a low-carbon future.

Prof. CAO Jiannong gives keynote speech at global blockchain summit

Prof. CAO Jiannong, Director of the Research Institute of Artificial Intelligence of Things (RIAIoT), Dean of the Graduate School, Director of the University Research Facility in Big Data Analytics, Chair Professor of Distributed and Mobile Computing and Otto Poon Charitable Foundation Professor in Data Science, delivered a keynote speech on decentralised data infrastructure for Web 3.0 at the 9th Global Blockchain Summit 2023 held in Shanghai. Prof. Cao said that Web 3.0 is marked by three characteristics: de-platforming and decentralisation—a single centralised platform will no longer be needed to control and manage user information; user data ownership—users will have complete control over their own information and identity; and tokenisation—the values of user-generated data and contents can be expressed in the form of tokens. He also pointed out that, the Web 3.0 environment can drive many innovations. Innovations in high application layers including decentralised finance (DeFi), finance gamification (GameFi) and social finance (SocialFi), are all about decentralised finance, i.e., the use of blockchain, smart contracts and digital identities to remove the unnecessary intermediate channels in traditional finance. GameFi and SocialFi apply the concepts and technologies of decentralised finance to games and social platforms respectively.  In addition to innovation at the application level, Web3.0 can also drive organisational, social and economic innovation.   Online coverage (Chinese only): Zhihu - https://polyu.me/3ZnxNXl China.com - https://polyu.me/3PKLUCD East Money - https://polyu.me/48mmi6m

RCMI Member explains sleep and insomnia from Chinese medicine perspective

Dr Jerry YEUNG, Management Committee Member of the Research Centre for Chinese Medicine Innovation (RCMI) and Associate Professor in the School of Nursing (SN), was featured in RTHK’s TV programme “Healthpedia”, sharing traditional Chinese medicine perspective on sleep and insomnia. Dr Yeung mentioned that Chinese medicine believes in the connection between emotions and organs, and five organs (heart, liver, spleen, lung and kidney) are linked to five basic human emotions (anger, joy, anxiety, sorrow, melancholy, fright); insomnia is most closely linked to the heart, and is also related to the liver, spleen and kidney. Dr Yeung also explained the relationship between dreaming and insomnia, and introduced the traditional Chinese medicine herbal formulae, acupuncture and acupoint massage that can effectively relieve insomnia.   Online review (Chinese only): RTHK – First Episode on 5 September 2023: https://polyu.me/3wGUIjF (03:42 - 18:00)  RTHK – Second Episode on 12 September 2023: https://polyu.me/3wGUIjF (03:42 - 18:00)

PolyU research team develops liquid metal microelectrodes for implantable bioelectronics

The interdisciplinary research team led by Prof. ZHENG Zijian, Associate Director of the Research Institute for Intelligent Wearable Systems (RI-IWEAR), Member of the Otto Poon Charitable Foundation Research Institute of Smart Energy (RISE), Chair Professor of Soft Materials and Devices, and Professor in the Department of Applied Biology and Chemical Technology, has developed liquid metal microelectrodes (μLMEs) which are suitable for skin-attachable and implantable electronic devices. The pioneering study “Wafer-patterned, permeable, and stretchable liquid metal microelectrodes for implantable bioelectronics with chronic biocompatibility”, was published in Science Advances. Wearable or implantable bio-electronic technology requires unique properties that are different from conventional electronics. The developed μLMEs are stretchable, soft and permeable, and can therefore be worn or implanted without causing discomfort or harm to the users. The conductive component of the μLMEs was made from eutectic gallium indium (EGaIn), a liquid metal alloy which allows the μLMEs to retain high conductivity under strain.
