Prof. Jerry YAN delivers keynote on energy transition at international conference

Prof. Jerry YAN Jinyue, Executive Committee Member of the Research Institute for Sustainable Urban Development (RISUD) and Chair Professor of Energy and Buildings, at the International Conference on New Energy Science and Electrification of Transportation held on 31 October 2023 in Xiong’an, China, delivered a keynote presentation titled “Energy Nexus: Research and Innovations without Borders — Inter-disciplinary research on energy transition”. Prof. Yan said that there are two sides of energy transition, one is by increasing the proportion of renewable energy sources, and the other is by targeting at the distributed energy generation and storage of end-users. In addition, Prof. Yan pointed out that energy systems involve multiple fields and so, future energy innovation is an interdisciplinary field, involving not only engineering, but also other disciplines.   Online coverage: Xinhua Net - https://polyu.me/3MrQGmG 光明網 - https://polyu.me/45Y5jF0 Toutiao - https://polyu.me/3FFQool

Prof. K. K. LING shares views on Northern Metropolis development at Master Insight Forum

Prof. K. K. LING, Associate Director of the Research Institute for Land and Space (RILS) and Director of Jockey Club Design Institute for Social Innovation, shared his views on the development of the Northern Metropolis in a panel discussion of the Master Insight Forum held on 27 October 2023. Prof. Ling believed that the Northern Metropolis has several implications for Hong Kong: (1) it reshapes the development pattern of “emphasising the south over the north”; (2) it establishes a “twin city” relationship between Shenzhen and Hong Kong; (3) it is a new driver of Hong Kong’s future development; (4) the speedy development of the Northern Metropolis is an irreversible trend; and (5) the development reflects the advantages of “one country, two systems” policy. Prof. Ling said that San Tin Technopole will be able to attract innovation and technology (I&T) talents and industries, and suggested developing Shenzhen Bay into a “golden inner bay”.

PolyU-led novel food waste-derived 3D printing materials to be showcased at InnoCarnival 2023

The novel food waste-derived 3D printing materials developed by the Research Institute for Future Food (RiFood) will be showcased at the InnoCarnival 2023 to be held from 28 October to 5 November 2023 at Hong Kong Science Park. Prof. WONG Ka Hing, Director of RiFood, said that food waste can be simply divided into two types. “The first type is kitchen waste, which mainly comes from households or restaurants. The second type is food/agro-waste generated by food processing plants. As these food/agro-wastes come from food factories, waste production is concentrated and the waste composition is relatively homogenous. Examples include spent coffee grounds, spent tea leaves, potato peels, etc. The innovative green technology we showcase is upcycling the spent coffee grounds and tea leaves into novel 3D printing materials,” he explained. 3D printing has become very popular in recent years, and Fused Deposition Modelling (FDM) is the one of the most commonly used 3D printing methods. FDM can print various tools with plastic as the main printing material. Prof. Wong said that their innovative green technology can combine spent coffee grounds/tea leaves with polylactic acid (PLA) to produce a novel 3D printing material. “This novel food waste-derived 3D printing material (up to 50% of food waste) can be used in FDM 3D printers without affecting its printing performance. With a strong tensile strength (10-40 MPa), the novel 3D printing material can be used for a wide range of applications, such as production of modular furniture and display goods,” he elaborated. This novel sustainable 3D printing material exhibits excellent ductility and can be used for printing shock-absorbing structures. To ensure compliance with the low-carbon policy, the novel 3D printing material is customisable, scalable, does not require any chemical additives during the mass production process, and its carbon footprint is about 36% lower than that of commercial PLA 3D printing material. The team is going to collaborate with a local coffee chain to produce eco-friendly 3D-printed furniture and display goods using their spent coffee grounds. Various 3D printed products made from spent coffee grounds will also be showcased at the Carnival.

RCRE-led green building material technologies to be showcased at InnoCarnival 2023

Two advanced technologies from the Research Centre for Resources Engineering towards Carbon Neutrality (RCRE) including the eco-cements synthesised from recycled solid wastes, and the eco-friendly radiative cooling coating UmiCoolTM, will be showcased at the InnoCarnival 2023 to be held from 28 October to 5 November 2023 at Hong Kong Science Park. The eco-cements developed by Prof. POON Chi-sun, RCRE Director, and his team, are produced from solid wastes including waste concrete, waste incineration ash, and waste glass. These eco-cements can capture, mineralise and store the carbon dioxide gas in the atmosphere, while enhancing the hydrophobic performance of concrete, hence greatly reducing the risk of flooding in extreme weather. The cooling coating UmiCoolTM developed by Prof. DAI Jianguo, RCRE Member, and his team, uses the principle of radiative cooling to cool the surface and interior of buildings or infrastructure under direct sunlight during the day. It can reduce the surface temperature by up to 6°C as compared to the ambient temperature without consuming any electricity.   Online coverage: Oriental Daily News - https://polyu.me/3tuzdDs Wen Wei Po - https://polyu.me/3FjcKvW

RiFood develops novel selenium nanoparticles for managing postmenopausal osteoporosis

October 20 2023 marks this year’s World Osteoporosis Day. On the same day, Prof. WONG Ka-hing, Director of the Research Institute for Future Food (RiFood) and Professor in the Department of Food Science and Nutrition (FSN), shared with the media his team’s latest research on the development of novel Cs4-selenium nanocomposites (Cs4-SeNPs) for managing postmenopausal osteoporosis. Selenium is an essential trace mineral to human health, playing important roles in many physiological functions. In the past decades, substantial evidences have demonstrated that Se deficiency is detrimental to bone microarchitecture and associated with osteoporosis, suggesting its crucial role in bone metabolism. Recently, selenium nanoparticles (SeNPs) have become a new research target, since they were found to possess remarkable bioactivity and lower toxicity compared to those selenocompounds commomly found in foods. Nevertheless, scientific research concerning their effects on bone health is currently very limited. By using the polysaccharide-protein complex isolated from Cordyceps sinensis, Prof. Wong has successfully prepared novel selenium nanoparticles (entitled “Cs4-SeNPs”), with well-characterised structure and high stability. Interestingly, Cs4-SeNPs (10μM) were found to markedly induce proliferation, differentiation, and mineralisation of the pre-osteoblast murine MC3T3-E1 cells. More importantly, Cs4-SeNPs (25-500μg/kg BW/d) exhibited promising in vivo bone protective efficacy against OVX-induced osteoporosis by promoting bone formation, inhibiting bone resorption, and improving bone microarchitecture after oral gavage for 6 weeks. This patented nanotechnology has gained wide recognition with various international awards, while the research findings have been recently published in Journal of Functional Foods. Further investigation on Cs4-SeNPs’ gastrointestinal stability, intestinal absorption and metabolism is now underway. The team look forward to collaborating with the industry in further development of related health food products and drugs.   Online coverage (Chinese only): CRHK - https://polyu.me/3RZVpj4 Oriental Daily News - https://polyu.me/3twkkjV am730 - https://polyu.me/46UdmUm Ta Kung Pao - https://polyu.me/46XUy6Q Wen Wei Po - https://polyu.me/48XfxIx Hong Kong Economic Journal - https://lnkd.in/gyW8bcHf dotdotnews - https://lnkd.in/gH3grVhZ   Read the full research paper: https://doi.org/10.1016/j.jff.2023.105832
