RIAM Member makes breakthrough discovery in structure and synthesis of 2D ferroelectrics

A research team led by Prof. ZHAO Jiong, Member of the Research Institute for Advanced Manufacturing (RIAM), Associate Professor in the Department of Applied Physics of The Hong Kong Polytechnic University (PolyU), has made significant discoveries in the research on 2D ferroelectrics and 2D van der Waals materials. The team unveiled a pioneering approach for the large-scale synthesis of Indium Selenide (In2Se3), and provided new insights into the critical mechanisms that underlie the characteristics of 2D van der Waals materials and bilayer 2D materials. In2Se3 is a promising 2D ferroelectric material but the large-scale synthesis of 2D In2Se3 films with the desired phase is still lacking. The team utilised transmission electron microscopy (TEM) technique to directly observe and analyse the ferroelectric domains, domain walls and other crucial features at the atomic level within the materials, and have successfully synthesised 2D In2Se3 films with pure phase. The findings were published in Nature Nanotechnology. Furthermore, the team unveiled the ultra-high plasticity of materials in 2D metal monochalcogenides such as InSe, and the complex vortex patterns with tunable characteristics in twisted-bilayer molybdenum disulfide (MoS2). The two findings have been published in Nature Materials and Science, respectively. These scientific discoveries significantly boost technological advancements in microelectronics, artificial intelligence and quantum information, and has promising prospects for diverse applications including high-density memory devices, energy conversion systems, sensing technologies and catalysis technologies. The studies were supported by PolyU’s Atomic Transmission Electron Microscopy Laboratory and contributions of the research team of Prof. Daniel LAU Shu-ping, Chair Professor of Nanomaterials and Head of the PolyU Department of Applied Physics; Prof. YANG Ming, Assistant Professor in the PolyU Department of Applied Physics; and Prof. LY Thuc Hue, Associate Professor of the Department of Chemistry of City University of Hong Kong.

Prof. SONG Haiyan featured on Now News on use of robotics and AI in hotel industry

Prof. SONG Haiyan, Director of Research Centre for Digital Transformation of Tourism (RCDTT), Associate Dean and Chair Professor of School of Hotel and Tourism Management (SHTM), Mr and Mrs Chan Chak Fu Professor in International Tourism, was interviewed by Now News to share his views on how robotics and AI can address manpower shortages and enhance customer experiences in the hotel industry. Prof. Song said, “Some people think that the development of AI and robotics may replace certain jobs in the hotel industry, and this is indeed true. However, the use of robotics and AI also creates opportunities for new and higher-level jobs. As the hotel and tourism industry evolves in the future, many new business operating models and applications of science and technology will emerge.” Online coverage: Now TV - https://polyu.me/3X2DREI (00:15 - 02:08) Yahoo HK - https://polyu.me/43gMAan

RiFood co-organises workshops to promote food upcycling and reduce food waste

The Research Institute for Future Food (RiFood) recently co-organised workshops with the aim of promoting food upcycling and reducing both food waste and carbon footprints. The workshop titled “From Waste to Worth: What Is Upcycled Food and Why Should We Try It?”, held in collaboration with the School of Hotel and Tourism Management (SHTM) and the Campus Facilities and Sustainability Office (CFSO) on 10 February 2025, discussed the significance of food upcycling in minimising food waste and lowering carbon emissions. Participants also had the opportunity to try upcycled snacks. Additionally, in the “Brew-tiful Workshop” co-organised with the Food and Wine Academy of SHTM on 11 February 2025, participants explored the art of crafting beers, upcycling coffee grounds, bread and fruit into beers with unique flavours, distinct from traditional wheat-brewed varieties.

PolyU and CSD sign MOU to promote upcycling of food waste and development of eco-friendly products

The Hong Kong Polytechnic University (PolyU) and the Correctional Services Department (CSD) signed a Memorandum of Understanding (MoU) today to jointly promote the upcycling of food waste and the development of environmentally friendly products, injecting new impetus into the sustainable development of the correctional industry. The MoU sets out a framework for collaboration between PolyU and CSD to jointly promote innovative development initiatives over the next five years, including the application of PolyU’s scientific research results on food waste upcycling to industrial production in correctional institutions; and the provision of vocational training to persons in custody (PICs) in the design and production of environmentally friendly products by PolyU to enhance their employability. The collaboration not only promotes environmental protection but also assists in the rehabilitation of PICs. Witnessed by Prof. Christopher CHAO, Vice President (Research and Innovation) of PolyU, and Mr NG Chiu-kok, Deputy Commissioner of Correctional Services (Rehabilitation and Management), the MoU was signed by Prof. WONG Ka-hing, Director of the Research Institute for Future Food and Professor of the Department of Food Science and Nutrition of PolyU, and Mr TONG Soen, Assistant Commissioner of Correctional Services (Rehabilitation). Prof. Chao said at the ceremony that PolyU has been tackling social challenges and promoting sustainable development through innovative research and translating research outcomes over the years. The “food waste-derived 3D printing material” patented technology covered in the collaboration project was developed by PolyU’s Research Institute for Future Food, which opens up a new way to tackle the problems of municipal food waste and greenhouse gas emissions in Hong Kong. Both parties will work together to create a mutual aid ecosystem, where new economic, ecological, and cultural value can be generated, contributing to the realisation of a cohesive society and sustainable development. Addressing the ceremony, Mr Ng said that the CSD has been committed to introducing green measures in correctional work to build an integrated and sustainable correctional system. The signing of the MoU marks an important milestone in the sustainable development of correctional work. The first phase of the collaboration involves the application of PolyU’s patented technology for making 3D printing material with spent coffee grounds to the industrial production work performed by PICs. PolyU will also provide vocational training in product design for PICs to develop more environmentally friendly spent coffee grounds products. The environmentally friendly spent coffee grounds products will be available for sale on the CSD Sports Association's online charity gift sales platform, Made In Prison, to promote messages of supporting rehabilitation and environmental protection to the public. All proceeds from the sale, after deducting necessary costs, will be donated to various local registered charities, providing PICs with opportunities to contribute to the community.
