RCTFF develops 3D cellular solar crystalliser to improve wastewater desalination

A study by the Research Centre of Textiles for Future Fashion (RCTFF), “3D Cellular Solar Crystallizer for Stable and Ultra-Efficient High-Salinity Wastewater Treatment”, was recently published in Advanced Science. The research aims to enhance the evaporation capability in seawater desalination. Solar-driven interfacial evaporation technology directly uses solar energy to evaporate water from brine and crystallise salts to achieve purification and desalination. However, the evaporation capability of the interfacial solar crystallisers used in existing technology remains a technical challenge. To address so, the research team developed an artificial tree solar crystalliser (ATSC), which was designed with a multi-branched and interconnected open-cell cellular structure that significantly increased evaporation surface. The ATSC achieved an ultra-high evaporation rate (2.30 kg m−2 h−1 during 2 h exposure) and high energy efficiency (128%) in concentrated real seawater; and maintained a stable evaporation rate (1.94 kg m−2 h−1) on average in concentrated seawater for 80 h continuous exposure. The ATSC can help minimise the discharge of high-salinity wastewater in industrial processes, marking a major step forward towards zero liquid discharge treatment.   Read the full article: http://doi.org/10.1002/advs.202305313

RCSV research shows efficacy of RLRL therapy in controlling myopia

A research conducted by Prof. HE Mingguang, Director of the Research Centre for SHARP Vision (RCSV) and Chair Professor of Experimental Ophthalmology, has proved that repeated low-level red-light (RLRL) therapy can significantly slow down the progression of myopia in children, and even reverse short-sightedness. Myopia was considered as an irreversible process of axial growth. Research found that the axial elongation of children receiving RLRL therapy was 70% less than those wearing normal spectacles. Furthermore, multiple clinical studies have demonstrated that up to 40% of RLRL-treated children showed axial length shortening one month following the therapy.   Online coverage: Oriental Daily News - https://polyu.me/3sW7Q5h Hong Kong Economic Times - https://polyu.me/46xJJri (subscription required) am730 - https://polyu.me/40Z7w2d Sky Post - https://polyu.me/40WTbmR Ta Kung Pao - https://polyu.me/411c7kG Line Today - https://polyu.me/46xYCK7 Sing Tao Daily - https://polyu.me/47xvW5u Headline Daily - https://polyu.me/40WnEkW Eastweek - https://polyu.me/49UO1vI Sunday Kiss - https://polyu.me/49TuaNA

Renowned Chinese medicine scholar to deliver a distinguished lecture on the development of acupuncture

PAIR cordially invites you to join our Distinguished Lecture on 8 December 2023 (Friday) at 11:00am–12:30 p.m. (Hong Kong Time) on the PolyU campus and via Zoom. The lecture, titled “Acupuncture in the United States: From Exploration to Accessibility” will be delivered by Prof. LAO Lixing, Professor and President of the Virginia University of Integrative Medicine (VUIM), USA. Since the 1970s, acupuncture has rapidly developed and received acceptance by the public and mainstream healthcare system in the United States. Evidence-based acupuncture played a major role in acupuncture development. Despite challenges and difficulties in acupuncture clinical research, sufficient evidence demonstrated the efficacy, effectiveness, and safety of acupuncture. In the lecture, Prof. Lao will introduce his 30 years of experience in acupuncture research and share his witness in the United States from exploration in early years to the accessibility in the current healthcare system.  Prof. Lao will also share his opinion on the challenges and difficulties in acupuncture clinical research. Prior to his position at VUIM, Prof. Lao was a Professor and the Director of the School of Chinese Medicine of The University of Hong Kong, holding Vivian Taam Wong Endowed Professorship in Integrative Medicine during 2013–2019. He was elected Vice President of the World Federation of Acupuncture and Moxibustion Societies (WFAS).  Graduated from the Shanghai University of Traditional Chinese Medicine (TCM) in 1983 and obtained a Ph.D. in physiology at the University of Maryland, Baltimore (UMB) in 1992.  Prof. Lao has been conducting research, practicing, and teaching acupuncture and TCM for 40 years.  He also published over 300 peer-reviewed scientific papers.  He currently serves as the Editor-in-Chief in the Journal of Integrative Medicine. Prof. Lao is also a Fellow of the PolyU Academy for Interdisciplinary Research. Don’t miss the chance to learn from distinguished scholar! Find out more and register at: https://polyu.hk/iUAHX

Free vision test mobile app “WHOeyes” launched in China

A mobile app for free vision test “WHOeyes”, developed by Prof. HE Mingguang, Director of the Research Centre for SHARP Vision (RCSV) and Chair Professor of Experimental Ophthalmology, was officially launched in China on 25 November 2023.  WHOeyes is the first vision test mobile app endorsed by the World Health Organization. It was launched globally earlier on the World Sight Day (12 October 2023). WHOeyes can assess users’ visual acuity and provide advice for protecting vision. Users can simply look at the cameras of smartphones installed with WHOeyes and follow the system instructions, and the app will measure both distance and near vision of users. The app is now available in six languages including Arabic, Chinese, English, French, Russian and Spanish.   Read more: https://www.who.int/news/item/12-10-2023-who-launches-the-whoeyes-app-on-world-sight-day Download from App Store: https://apps.apple.com/us/app/whoeyes/id6463576815 Download from Google Play: https://play.google.com/store/apps/details?id=org.who.whoeyes   Online coverage: GD Today - https://polyu.me/3QWAFX9 East Money - https://polyu.me/3Ge9mCZ (Chinese only) NetEase - https://polyu.me/3RidC9J(Chinese only)

PAIR to organise distinguished lecture on high performance computing

PAIR cordially invites you to join our Distinguished Lecture on 6 December 2023 (Wednesday) at 10:15am–11:45am (Hong Kong Time) on PolyU campus and via Zoom. The lecture, titled “An Overview of High Performance Computing and Future Requirements” will be delivered by 2021 A. M. Turing Award Laureate Prof. Jack DONGARRA, University Distinguished Professor of Computer Science, University of Tennessee, USA. You can review the lecture online now! In the lecture, Prof. Dongarra will discuss how high performance computing has changed over the last ten years and its future trends. These changes have had and will continue to impact our numerical scientific software significantly. A new generation of software libraries and algorithms are needed for the effective and reliable use of (wide area) dynamic, distributed, and parallel environments. Some of the software and algorithm challenges have already been encountered, such as the management of communication and memory hierarchies through a combination of compile-time and run-time techniques, but the increased scale of computation, depth of memory hierarchies, range of latencies, and increased run-time environment variability will make these problems much harder. Prof. Dongarra specialises in numerical algorithms in linear algebra, parallel computing, the use of advanced computer architectures, programming methodology and tools for parallel computers. He holds appointments at the University of Manchester, Oak Ridge National Laboratory, and the University of Tennessee, where he founded the Innovative Computing Laboratory. In 2019 he received the ACM/SIAM Computational Science and Engineering Prize. In 2020 he received the IEEE-CS Computer Pioneer Award. He is a Fellow of the AAAS, ACM, IEEE, and SIAM; a foreign member of the British Royal Society and a member of the U.S. National Academy of Sciences and the National Academy of Engineering. Most recently, he received the 2021 ACM A.M. Turing Award for his pioneering contributions to numerical algorithms and software that have driven decades of extraordinary progress in computing performance and applications. Prof. Dongarra is also a Distinguished Fellow of the PolyU Academy for Interdisciplinary Research. Review the lecture online!
