PolyU develops low-carbon marine self-healing concrete to achieve carbon neutrality with supports from Green Tech Fund

The Hong Kong Polytechnic University (PolyU) is committed to advancing green technology to help tackle the pressing need for global sustainability. A team of interdisciplinary experts from the Department of Civil and Environmental Engineering has developeda low-carbon marine self-healing concrete, which holds promising potential for marine construction materials and coastal engineering applications.Contributing to carbon neutrality,this initiative has received approximately HK$6.03 million from the HKSAR Government’s Green Tech Fund for a duration of 24 months. The project “Marine self-healing concrete with biomineralisation-enhanced construction waste for long-term decarbonisation” is led by Prof. LI Xiangdong, Dean of the Faculty of Construction and Environment, Chair Professor of Environmental Science and Technology, and Ko Jan Ming Professor in Sustainable Urban Development at PolyU. The team members are Prof. Chi Sun POON, Head of Department, Chair Professor of Sustainable Construction Materials, and Michael Anson Professor in Civil Engineering, Prof. YU Tao and Prof. LENG Zhen, with Dr SUN Xiaohao, Research Assistant Professor as the co-principal investigator. Due to the scarcity of natural aggregate, scientists have been seeking effective alternatives.This project aims to design and develop low-carbon marine self-healing concrete by incorporating biomineralisation-enhanced recycled aggregates made from waste concrete. By employing biomineralisation technology, the marine carbon-capturing bacteria will utilise carbon dioxide (CO2) to accelerate carbonisation and improve the performance ofrecycled aggregates. This approach helps reduce CO2 emissions and facilitates the recycling of construction waste, offering a broad application in marine construction materials and coastal engineering. In addition, this microbial concrete structure possesses self-healing properties that enhance its durability, providing a significant advantage in achieving long-term decarbonisation and sustainability. 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 comprehensive design guidelines for marine self-healing concrete, optimised mixing techniques, and valuable insights into the influence and environmental performances of low-carbon marine self-healing concrete on marine ecology. Prof. Li said, “Through the innovative use of biomineralisation and recycled aggregates in marine concrete, this project drives progress in the production of marine construction materials and  pioneers new solutions in sustainable construction to accelerate the development of related industries. Our goal is also to address global environmental challenges such as reducing carbon emissions from construction waste, and promoting its recycling to alleviate landfill pressures. This approach conserves land resources and mitigates environmental hazards, making a contribution towards achieving carbon neutrality and the long-term sustainable development of Hong Kong and the Greater Bay Area.” The Green Tech Fund was established in 2020 to provide better and more focused funding support to research and development projects which help Hong Kong decarbonise and enhance environmental protection.

PolyU researchers develop breakthrough method for self-stimulated ejection of freezing droplets, unlocking cost-effective applications in de-icing

Water droplets under freezing conditions do not spontaneously detach from surfaces as they do at room temperature due to stronger droplet-surface interaction and lack of an energy transformation pathway. Since accumulated droplets or ice have to be removed manually or with mechanical equipment, which is costly and inefficient, preventing droplet accretion on surfaces is both scientifically intriguing and practically important. Researchers at The Hong Kong Polytechnic University (PolyU) have invented a ground-breaking self-powered mechanism of freezing droplet ejection that allows droplets to shoot themselves away, paving the way for cost-efficient and promising technological applications. Published in Nature Chemical Engineering as the cover feature for its last December issue, the research project “Freezing droplet ejection by spring-like elastic pillars” is led by Prof. Zuankai WANG, Associate Vice President (Research and Innovation), Kuok Group Professor in Nature-Inspired Engineering and Chair Professor of the PolyU Department of Mechanical Engineering, and Prof. Haimin YAO, Associate Professor of the PolyU Department of Mechanical Engineering. First co-authors include Postdoctoral Fellow Dr Huanhuan ZHANG, PhD student Mr Wei ZHANG, Research Assistant Professor Dr Yuankai JIN, and PhD student Mr Chenyang WU. The discovery of the self-ejection phenomenon in freezing droplets was inspired by a fungus capable of shooting its spores away through osmosis-induced volume expansion. Noting that a similar volume expansion occurs when water droplet is freezing, the research team has replicated the self-shooting mechanism found in the fungi and developed a structured elastic surface (SES) with spring-like pillars and wetting contrast that allows for the spontaneous ejection of freezing water droplets. The SES structure is designed to accelerate the ejection velocity and enlarge the kinetic energy transformation of freezing droplets. When the freezing droplet undergoes volume expansion, it compresses the pillar of SES. The volume expansion work is first converted to and stored as elastic energy in the pillar within tens of seconds, and then to be transformed into the droplet’s kinetic energy rapidly within milliseconds. This thousandfold reduction in timescales leads to sufficient kinetic energy to drive freezing droplet ejection. The simple SES structure, after parameter design, is effective in ejecting freezing droplets without external energy input and even against the forces of wind and gravity. It can be applied to aircraft, wind blades or cable lines to prevent hazards caused by ice accretion. Dr Huanhuan Zhang said, “It is exciting that we, for the first time, introduce a self-powered ice removal concept that will offer a wide range of innovative solutions. We will continuously improve the design of SES, allowing it to be manufactured at various scales and at a low cost to meet societal needs.” Furthermore, the theoretical model developed in the research elucidates the factors determining the successful onset of the freezing droplet ejection phenomenon, with scalable design exhibiting potential practicability in various fields. Prof. Wang envisions, “This nature-inspired research paved the way for numerous impactful applications. We believe that the freezing droplet ejection, as a prototype, could stimulate the development of self-powered concepts and methods for a wide range of purposes such as de-icing, energy harvesting and soft robotic applications.” Specifically, droplet ejection induced by volume expansion enhances understanding of multi-phase freezing dynamics for anti-icing applications. Prof. Yao remarked,“Our research demonstrates a strategy to efficiently harness and utilise the volume expansion work of freezing droplets to generate ballistic motion. This could subsequently expand the application of energy conversion phenomena, and inspire the development of droplet-based energy generators and soft robotic catapults.”
