Prof. KEE Chea-su introduces world’s first portable high-definition corneal topographer

Prof. KEE Chea-su, Associate Director of the Research Centre for SHARP Vision (RCSV) and Head and Professor of the School of Optometry, was featured on HOY’s TV programme “InnoAction” to introduce the world’s first portable High-Definition Corneal Topographer “K-Shape” developed by his team. The innovation leverages artificial intelligence-driven algorithms to accurately measure corneal power, provide early diagnosis of vision problems such as corneal astigmatism and corneal ectasia, and simplify the diagnosis process, enabling it to be completed in as little as one minute. The innovation was awarded the Prize of the Saudi Arabian Delegation and Gold Medal in the 49th International Exhibition of Inventions Geneva.

Prof. WONG Ka-hing on RiFood’s sustainable hydroponics research and its applications

Prof. WONG Ka-hing, Management Committee Member of PAIR, Director of the Research Institute for Future Food (RiFood) and Professor in the Department of Food Science and Nutrition, penned a bylined article in Sing Tao Daily, introducing the Institute’s research and applications in hydroponics. Prof. Wong mentioned in the article that his research team received funding from the Sustainable Agriculture Development Fund of the Agriculture, Fisheries and Conservation Department this year to further develop bio-fortification technology for precision hydroponics based on existing patented technologies to increase the mineral or micronutrient content of vegetables during the planting process. The team specifically addressed the common inadequate intake of calcium, iron and iodine among Hong Kong residents by adding these micronutrients to commonly eaten vegetables, thus allowing the public to meet their nutritional needs easily and affordably through their daily diet, and providing targeted solutions for natural nutritional supplementation. He also believes that although hydroponic vegetables are not yet popular in Hong Kong, hydroponic farming has significant environmental benefits and is regarded as an important step in sustainable agriculture development.   Online coverage: Sing Tao Daily - https://polyu.me/4huD0Fb (subscription required)( Chinese only)

RILS scholar co-authored study reveals summer meltwater storage in Greenland ice sheet

Prof. CHEN Jianli, Core Member of the Research Institute for Land and Space (RILS) and Professor in the Department of Land Surveying and Geo-Informatics, and an international group of researchers published a study in Nature that unveils a substantial amount of meltwater being temporarily stored within the Greenland ice sheet during summer. The study was led by Dr RAN Jiangjun, Associate Professor at the Southern University of Science and Technology. For the first time, the team quantified meltwater storage using positioning data. The researchers employed data from the Greenland GPS Network (GNET), a network comprising dozens of stations in Greenland, to continuously monitor the vertical displacements of bedrock at different stages of the melt season. The mass of meltwater is a factor that causes the bedrock to shift downwards. The team developed an innovative method for explaining the detected vertical shifts based on the meltwater mass. The Greenland ice sheet is currently the largest contributor to global sea level rise. If it completely melts, it can potentially raise the mean sea level by seven meters. The study provides a new perspective on the movement and storage of meltwater within the ice sheet during the summer months, bringing important discoveries for addressing pressing environmental challenges on Earth.   Read more: https://www.nature.com/articles/s41586-024-08096-3

These include precise positioning algorithms and data quality analysis for Global Positioning System (GPS)/Global Navigation Satellite System (GNSS), ionosphere scintillation monitoring and 3D Total Electron Content (TEC) modelling, impact of space weather on satellite navigation and flight operation, monitoring of atmospheric water vapor and 3D modelling, retrieval and calibration of satellite remote sensing water vapor data, and assimilation of atmospheric water vapor into Numerical Weather Prediction (NWP) models, etc. 

Prof. Daniel LAU shares electrocatalytic carbon dioxide reduction system on RTHK radio programmes

Prof. Daniel LAU, Associate Director of the Photonics Research Institute (PRI), Key Member of the Research Centre for Deep Space Explorations (RCDSE), Head of the Department of Applied Physics and Chair Professor of Nanomaterials, was featured in the RTHK radio programmes, including “Under the Sun” on 20 and 27 October 2024, and “Infinite Future” on 26 October 2024.  In the programmes, Prof. Lau introduced the novel electrocatalytic carbon dioxide reduction system developed by his team. This system can efficiently convert carbon dioxide (CO2) into ethylene, a raw material for plastics, thus achieving a carbon-negative effect. Prof. Lau is currently collaborating with the industry to conduct research on improving this device and enhancing its stability, hoping to apply this technology to overseas petrochemical plants or waste-to-energy devices in the near future.  Prof. Lau also hopes to collaborate with relevant government departments of the Hong Kong Special Administrative Region, such as the Environment and Ecology Bureau, to apply this technology to local waste-to-energy facilities to convert the carbon dioxide emitted from incinerators into ethylene. Prof. Lau also shared that this “catalyst material test device” has been carried into space along with the aerospace programme of the China National Space Administration to test for its stability in space.   Online coverage: RTHK Under the Sun (27 October 2024) - https://www.rthk.hk/radio/radio1/programme/underthesun/episode/984300 RTHK Under the Sun (20 October 2024) - https://www.rthk.hk/radio/radio1/programme/underthesun/episode/982843 RTHK Infinite Future - https://www.rthk.hk/radio/radio1/programme/infinitefuture/episode/984158
