RISUD Joined as a Signatory of the BEC Low Carbon Charter

Climate change is one of the most urgent global challenges of our time. Through the Paris Agreement of the United Nations Framework Convention on Climate Change, the global community commits to limit the rise of global average temperature, and hence Hong Kong also has an obligation to develop a long-term decarbonization strategy. With the support of business leaders and the Environment Bureau, Business Environment Council (BEC) (商界環保協會) has established the BEC Low Carbon Charter in March 2019 to mobilise companies from all sectors to collectively contribute towards Hong Kong’s long-term decarbonization through their pledge to set and achieve carbon reduction goals. In 2021, we are grateful to announce that Research Institute for Sustainable Urban Development (RISUD) becomes one of the signatories of the Charter. Prof. Xiangdong LI, the Director of RISUD, attended the signatory ceremony organized by BEC to receive a certificate of recognition on 16 April 2021. RISUD will continually commit to the target settings and put efforts in the low-carbon practices.

Prof. Meng Ni Co-authored A Research Article In Nature On Fuel Cells

In collaboration with Nanjing Tech University (China) and Colorado School of Mines (USA), Prof. Meng Ni co-authored a research article entitled “Thermal-expansion offset for high-performance fuel cell cathodes” in Nature. The first author, Dr. Yuan Zhang, worked in Prof. Meng Ni’s lab for 1 year where she conducted part of the experimental research reported in this Nature paper. The second author, Dr. Bin Chen (now an Assistant Professor at Shenzhen University, China), received his PhD in 2018 from BRE under supervision of Prof. Meng Ni. The corresponding authors are Prof. Zongping Shao and Prof. Wei Zhou, who are supervisors of Dr. Yuan Zhang and are both from Nanjing Tech University. High temperature solid oxide fuel cells (SOFCs) have the potential to replace conventional thermal power plants for energy conversion. One challenge for SOFC commercialization is thermo-mechanical instability due to mismatch in thermal expansion behaviour between different fuel cell components, which can cause cell performance degradation or even failure. In this research article, a novel electrode development strategy is proposed by compositing a cobalt-based perovskite with high electrochemical activity and large thermal expansion coefficient with a negative thermal expansion material. A new interface is formed between the two materials. A-site deficiencies in the perovskite are also observed. As a result, the composite electrode shows both high electrochemical activity and excellent thermos-mechanical stability. This research provides a new strategy for the development of high performance and durable solid oxide fuel cells for efficient and clean power generation.

1st Prize of the CIC Construction Innovation Award 2019 by Construction Health and Safety Research Group of RISUD

A licensed technology of an early heat-stress warning system that was developed by the Construction Health and Safety Research Group, Division of Urban Infrastructure of Research Institute for Sustainable Urban Development (RISUD), PolyU and incorporated into SmartWorks, an end-to-end solution provided by Smartone Mobile Communications Ltd. to promote and manage worksite safety, has won the 1st Prize of the CIC Construction Innovation Award 2019 in the category of Construction Safety. Led by Prof. Albert Chan, Associate Director of RISUD and the Group Leader of Construction Health and Safety Research Group, his research group pioneered the early-warning system to monitor the heat strain levels of workers when they are performing their tasks in hot weather. An indispensable component of SmartWorks is the Heat Stress Artificial Intelligence Engine, which integrates technologies with 5 key smart services, namely, Smart Helmet, Smart Health Station, Environment Station, Dump Truck Management and Danger Alert & Access Control. It is a prime example of what can result from a close collaboration between academe and industry. The Construction Innovation Award was organized by the Construction Industry Council (CIC) on a biennial basis since 2015, with the aim to spearhead the development, promotion and implementation of new construction materials, methods, technologies for enhancing the competitiveness of the construction industry. The same research group won the Local Grand Prize of the Inaugural Construction Innovation Award in 2015 for their innovative development of anti-heat stress uniforms, which have been adopted as a standard work wear for construction workers in all government funded projects since 2017.
