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

Prof. Nathanael JIN Ling, Member of the Research Institute for Future Food (RiFood) and 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.

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.

PolyU trains ambassadors to support mental health of carers of persons with disabilities

With funding support from Phase 2 of the Mental Health Initiatives Funding Scheme, The Hong Kong Polytechnic University (PolyU) collaborated with the Spastics Association of Hong Kong (SAHK) and the New Life Psychiatric Rehabilitation Association (NLPRA) in the project titled “Enhancing the Mental Health of Carers of Persons with Disabilities with Support Services Delivered by Trained Carer Support Ambassadors”, which aims to implement a short-term certificate programme for frontline workers such as occupational therapy assistants, rehabilitation assistants, patient care assistants and welfare workers to become Carer Support Ambassadors who will deliver mental health support to carers of persons with disabilities.  Under the project, 25 frontline workers were trained to become Carer Support Ambassadors, providing support to 110 carers.  PolyU held a symposium cum graduation ceremony on 16 January 2025, bringing together carers, ambassadors and experts participating in the project to celebrate project achievements. The event was graced by the presence of leaders in mental health profession, including Prof. Hector TSANG, Principal Investigator of the project, Chair Professor of Rehabilitation Sciences, and Member the Mental Health Research Centre (MHRC); Mr Fletch CHAN, Commissioner for Rehabilitation of the HKSAR; Ms Maggie LEUNG, Assistant Director (Rehabilitation & Medical Social Services), Social Welfare Department of the HKSAR; and Prof. Sylvia CHEN, Associate Dean of the Faculty of Health and Social Sciences, Chair Professor of Social and Cultural Psychology, and Interim Director of MHRC. At the symposium, different parties in the project gave sharing and keynote presentations on the project details and outcomes.  Prof. Tsang gave a brief overview about the project, while Ms Edith HUNG of SAHK and Ms Sara CHAN of NLPRA shared the experiences and benefits from participating in the project.  Dr TSUI Chi-man, Research Assistant Professor in the RS Department, who is also a member of the project team, explained the components of the training programme, which included common mental health issues related to carers, therapeutic communication, lifestyle redesign, complementary approaches for mental health, and useful skills to manage crisis.  Another project team member, Dr Erin LU, Research Assistant Professor in the same department and Member of MHRC, gave details about the Pilot Program on Carer Mental Health Support, which provided carers with various support services including ongoing monitoring of mental health using psychological scales, peer support workshops, and support in accessing professional help for individuals in need. The program was delivered by the train ambassadors. At the graduation ceremony, two carers and three trained ambassadors participating in the project gave heartful sharing about their first-hand experiences in the project, explaining how they benefitted from receiving proactive mental health support and participating in meaningful ambassador services respectively.  The officiating guests also presented certificates to trained ambassadors attending the event. The event concluded with resounding success, not only promoting greater awareness of the mental health of carers of persons with disabilities, but also building connections among the higher education, social welfare and government sectors for future collaborations in the development of carer mental health support policies and services.
