Prof. Nathanael JIN writes commentary on microbial risks of plastic pollution for Nature prediction service

Prof. Nathanael JIN Ling, Member of the Research Institute for Sustainable Urban Development (RISUD), and Assistant Professor in the Department of Civil and Environmental Engineering and the Department of Health Technology and Informatics, was invited by Nature to contribute a commentary titled “What harmful microbes are lurking in the world’s 7 billion tonnes of plastic waste?”.   In the paper, Prof. JIN and his team highlighted the microbial risks associated with plastic pollution and proposed a global strategy to address these challenges. Plastic debris creates a new ecological niche for microorganisms, forming a new ecosystem known as the “plastisphere”. The paper outlines the potential risks of plastisphere microbiomes pose to ecosystem functioning and the health of humans and other organisms. To develop a comprehensive global strategy, the paper suggests six priorities: quantifying effects, redefining plastic pollution, sustaining funding, establishing expert panels, adjusting management strategies and protecting people.   Read the full paper: https://doi.org/10.1038/d41586-024-03150-6  

Prof. Vivien LU integrates green radiative cooling coating with photovoltaics for energy saving in buildings

The PolyU Carbon Neutrality Funding Scheme aims to support the application of university research outcomes and to take the campus as a testbed to apply research solutions, with a goal of achieving carbon neutrality on campus and supporting Hong Kong’s goal of reaching carbon neutrality by 2050. With support from the Scheme, Prof. Vivien LU Lin, Member of the Otto Poon Charitable Foundation Research Institute for Smart Energy (RISE), Research Institute for Sustainable Urban Development (RISUD) and Research Centre for Resources Engineering towards Carbon Neutrality (RCRE), and Professor of the Department of Building Environment and Energy Engineering, and her research team, has integrated the solar-driven adaptive radiative cooling (SARC) coating they developed, with bifacial solar photovoltaics (PV) to achieve synergistic enhancement in thermal management and power generation, transforming buildings from energy consumers into energy harvesters. The team is planning to install bifacial PV panels on the rooftops of the under-construction PolyU Kowloon Tong Student Hostel, with new coating applied on the corresponding area under the panels, to enhance power generation while radiatively cooling the buildings.   The carbon dots (CDs)-driven photoluminescent radiative cooling nanocoating can be applied to building rooftops and exterior walls. This novel coating can automatically adjust its absorption and emission of solar and thermal radiation in response to changes in environmental temperature or light conditions, helping to mitigate the heat island effect caused by building materials. It uses photoluminescence technology to convert ultraviolet light into visible light, thereby improving the absorption and utilisation of light by PV and increasing its conversion efficiency.   Compared to traditional coatings, this novel coating can effectively improve effective daytime solar reflectance from 92.5% to 95%, increase the cooling effect by 10% to 20%, and reduce the temperature by up to 25°C when applied to concrete rooftops. This nanocoating is environmentally friendly, water-soluble, volatile organic compounds (VOCs)-free, and can be produced in various colours, thus demonstrating significant application potential.   Press Release: https://www.polyu.edu.hk/media/media-releases/2024/0924_polyu-researchers-unveil-novel-carbon-dots-driven-green-radiative-cooling-coating/ Online coverage: Sing Tao Headline - https://polyu.me/4hofXLG (Chinese only)

Director of RISUD receives Green Tech Fund to achieve carbon neutrality

The Hong Kong Polytechnic University (PolyU) is committed to advancing green technology to tackle the pressing need for global sustainability. PolyU researchers have developed a groundbreaking project aimed at designing and developing low-carbon marine self-healing concrete, which holds promising potential for marine construction materials and coastal engineering applications. This initiative will contribute to long-term decarbonisation efforts and has received support from the Green Tech Fund. The project titled “Marine self-healing concrete with biomineralization-enhanced construction waste for long-term decarbonization” is led by Prof. LI Xiangdong, Director of RISUD, Dean of Faculty of Construction and Environment (FCE), Chair Professor of Environmental Science and Technology, and Ko Jan Ming Professor in Sustainable Urban Development at PolyU. It has been awarded approximately HK$ 6.03 million from the Green Tech Fund for a duration of 24 months. This project is focused on designing and developing low-carbon marine self-healing concrete by incorporating biomineralization-enhanced recycled aggregates (RAs). Marine carbon-capturing bacteria will utilise carbon dioxide (CO2) to accelerate carbonisation and improve RAs, thereby addressing the issue of scarce natural aggregates, reducing CO2 emissions, and achieving the recycling of construction waste. In addition, this microbial concrete structure possesses self-healing properties that enhance its durability, providing a significant advantage in achieving long-term decarbonization and sustainability objectives. Field testing and lifecycle assessments will be conducted to ensure that the new concrete meets the stringent standards of durability and marine ecosystem quality. Anticipated results include a comprehensive design guideline for marine self-healing concrete, optimised mixing techniques, and valuable insights into the influence and environmental performances on marine ecology. In promoting the recycling of construction waste, conserving land resources, and mitigating environmental hazards, this project also drive progress in the production of marine construction materials and the subsequent development of related industries. Consequently, it contributes towards achieving carbon neutrality and fostering sustainable development within the Greater Bay Area. The Green Tech Fund (GTF) was established in 2020 to provide better and more focused funding support to research and development projects which can help Hong Kong decarbonise and enhance environmental protection.

Prof. Raymond WONG , RISUD Executive Committee Member, discusses enhancing organic solar cells for carbon reduction on RTHK Programme Infinite Future

Prof. Raymond WONG Wai-yeung, Executive Committee Member of the Research Institute for Sustainable Urban Development (RISUD), Associate Director of the Otto Poon Charitable Foundation Research Institute for Smart Energy (RISE), Member of the Research Institute for Intelligent Wearable Systems (RI-IWEAR) and the Research Institute for Sports Science and Technology (RISports), and Dean of the Faculty of Science, was featured in the RTHK programme Infinite Future, sharing how enhancing the photovoltaic (PV) efficiency of organic solar cells can help reduce carbon emissions.   Prof. Wong’s current research focus is on the design and preparation of novel high-performance photofunctional materials, and optoelectronic applications, particularly the luminescence and stability of these materials. His team has developed high-performance organic light-emitting diodes (OLEDs) with various colour emissions. Through molecular design, the team has developed a type of novel high-performance deep‐blue thermally activated delayed fluorescence (TADF) materials. OLEDs made with this deep-blue material have achieved an external quantum efficiency of over 35%, which is one of the highest in the world.   The team has also achieved a PV conversion efficiency of over 19% in organic solar cells using transition metal complexes. The ultra-thin and highly flexible characteristics of organic solar cells can be integrated with wearable electronic devices, enabling these wearable electronics to be self-powered using sunlight.   Prof. Wong also mentioned that the future research directions for these two types of optoelectronic devices are mainly further improving energy conversion efficiency through the molecular design of high-performance active materials and the structural design of devices; enhancing their stability and lifespan; and developing organic semiconductor electronic technologies and applications. He believes that achieving low-toxicity or non-toxic active materials in the future can help reduce environmental pollution and achieve sustainable development.   Online coverage: RTHK - http://polyu.me/3Z2YSza (Chinese only)
