Stacking Blocks into a Building: An Innovation in Construction
創新的拼裝積木式建築法
Shortages and unaffordable prices are the unsolved housing problems in Hong Kong. To increase the housing supply and reduce construction costs, we need to change the traditional way of building with innovations. Modular Integrated Construction (MiC) is an innovative method that revolutionises the construction industry. With the aid of the Building Information Modelling (BIM) technology, project teams fabricate building modules inside the factory, truck them to the site, and then stack them on top of each other to construct a building. Such modular construction offers a novel approach that is faster, greener, and smarter than ever.

Safeguarding the Digital Frontier: Next-generation of Cybersecurity
Software has played a pivotal role in every aspect of society nowadays. Yet, vulnerabilities have become increasingly pervasive, jeopardizing the safety and reliability of the critical software infrastructures on which our society relies. It can cause significant damage (financial losses, data breaches, or even life-threatening situations). For example, Meltdown and Spectre, discovered in 2016, make most modern CPUs and operating systems exploitable and leak administrator privileges. The 737 Max aircraft may crash due to vulnerable software in its operating system. As software systems grow in size and complexity and rapidly evolve, we face the fact that cybersecurity will become one of the main topics for future generations. How should we tackle these explosive vulnerabilities? How should we have a happy life without the threat of security?

Climate Change and Nuclear Power
核能在氣候變化中的角色
Climate change has far-reaching socio and economic impacts across the globe, some people even go to the extent of saying that climate change is a real threat to human civilization. This to some extent has some truths in it – from heatwaves to hurricanes, floods to famine. All of these disasters can certainly threaten our existence on earth. In order to avoid all these disasters to occur, all the countries need to have consolidated effort to reduce CO2 emission (a major culprit causing global warming). As a member of the global village, Hong Kong has also played its part. As announced by the Hong Kong Chief Executive’s 2021 Policy Address, Hong Kong is committed to achieving carbon neutrality by 2050. The talk will also explain the pros and cons of various fuel sources, and the importance of a balance fuel mix for a well-developed city like Hong Kong to reduce the Carbon dioxide emission on the one hand and maintain the vibrant economic activity of the city on the other hand. The talk will then examine how nuclear power can work with other renewable energy sources to keep global warming to below 1.5 degrees, according to the latest report by the Intergovernmental Panel on Climate Change (IPPC). The talk will also present the public concern about nuclear safety and the lessons learnt in the 3 major nuclear accidents. Finally, the talk will explain the development of the nuclear industry in China and also potential opportunity for Hong Kong.

Depending on the request of the participants, a guided tour can be organised after the talk to visit the CityU’s CLP Power Low Carbon Energy Education Centre.

MetaSLAM: Towards long-term and Large-scale General AI & Robotics Metaslam
面向長航程大規模的通用機器人技術
Parallel with the development of autonomous driving and space robotic exploration, the requirements for long-term and large-scale robotic navigation in field environments is increasing. However, in most GPS-denied applications, such as MARS colonizing, underground mining, and forest exploration, the major restriction for robustly long-term and large-scale robotic operations lies in their localization, mapping, and cooperation ability. In the real-world navigation task, robotics’ localization and mapping could be affected by the viewpoint difference and appearance changing, which can indirectly cause troubles in multi-agent cooperation. In this talk, we will focus on our current projects with DARPA and NASA and investigate our solution for UAV, UGV, and multi-agent systems in robotics applications, which include:
• Large-scale UAV Localization with Multi-Domain Transfer
• Large-scale Multi-Agent Mapping with Unknown Initials
• Asynchronous Multi-Agent Exploration for Long-term Navigation
• Bio-inspired Robotic Memory System for Lifelong SLAM

Thinking Theoretically in Human-computer Interaction Research
Human–computer interaction (HCI) is often perceived as a largely technical, practical, and industry-centered field of study, focusing on the usability and design of technological products or services. Although such perception is partly true, HCI is really a transdisciplinary integration that requires theoretical thinking of why and how humans interact with technology in a certain way. This talk will draw on the variable-centered and heuristic approaches to the study of communication technology, and demonstrate theoretical mechanisms by which technological affordances of emerging media, such as smartphones, smartwatches, and the Internet of Things, contribute to shaping user perceptions of the technology and of transmitted media content.

Adolescent mental health – posttraumatic growth
People of all ages can experience mental health issues in their life courses. Adolescence is incredibly challenging in human growth and development. Experiencing unpleasant, significant life events or even traumatic experiences does not necessarily lead to post-traumatic stress disorder.  Research and real-life experiences of my students show that traumatic experiences made them even stronger, and they have a thriving life, which proves post-traumatic growth is real. So, adolescents who are having negative life experiences or mental health issues do not give up on recovery.  You can have a promising future.

Aquatic Animal Virtopsy Lab - Health Assessment of Marine Tetrapods
海洋動物影像解剖研究組－當海豚遇上海龜？
Since 2014, our team has been applied a cutting-edge technique named ''virtopsy'' on local Cetacean Stranding Investigation. This technique was later extended to the research on stranded sea turtle since 2019. This technique enhances better understanding and gives insights into health conditions and life history of the stranded aquatic animals, and their injuries and deaths caused by human interactions. The collected data enables assessment of aquatic animals' health and provides an important reference to the development of a unique centralised database and long-term strategies for conservation of aquatic animals. Such a complete ecosystem indicator may eventually support the conservation and policy decision for all oceans, leading to an "One Ocean-One Health" paradigm.

自2014年起，我們研究組率先應用影像解剖在香港鯨豚擱淺調查的研究，並在2019年延伸至在本港擱淺的海龜。這種創新科技能協助研究人員進一步瞭解海洋動物的健康狀況、其生活史與及由人類活動所造成的損傷和死亡。這些資料有助評估動物健康情況，並可用以建立獨特的資料庫，以協助制定動物保育的長遠策略，以至為整個海洋生態制定保育措施與政策的生態系統指標，從而達至「海洋健康一體化」的目標。

CSI of the Cetaceans: Virtopsy and One Ocean One Health
鯨豚法醫：影像解剖與海洋健康一體化
Cetaceans (whales, dolphins and porpoises) are prime sentinel species because of their long life spans, long-term coastal residences, high trophic level diets, and unique fat storage that can serve as depots for anthropogenic toxins. Cetaceans may be exposed to environmental stressors such as chemical pollutants, harmful algal biotoxins, and emerging pathogens. Since many cetaceans share the coastal environment with humans and consume the same food, they also may serve as effective sentinels for public health concerns.

This talk aims to introduce a cutting-edge technique named ''virtopsy'', which has been applied on Cetacean Stranding Investigation in Hong Kong and adjacent waters since 2014. This technique enhances better understanding and gives insights into health conditions and life history of the stranded carcasses and their injuries and deaths caused by human interaction. The collected data allow measurement of cetacean health trends and provide an important reference to the development of a unique centralised database and long-term strategies for the conservation of local cetaceans. Such a complete ecosystem indicator may eventually not only benefit the cetaceans being studied, but also human health as well by keeping the entire marine environment healthy and supporting the conservation and policy decision for all oceans, leading to an ‘One Ocean−One Health’ paradigm using cetaceans as sentinels of potential emerging hazards.

Dark Matter and Dark Sectors
暗物質和暗域
Modern cosmology and astrophysics reveal that 85% of the matter in the universe is comprised of dark matter, which seemingly interacts with ordinary matter only through gravitational forces. Despite compelling evidence for its existence, the properties of dark matter remain largely unknown. Considering that ordinary matter consists of a variety of particles engaging in complex interactions, it is natural to hypothesise that dark matter is not "alone". It could be part of the "dark sectors", a collection of hidden particles such as dark photons and dark Higgs bosons. These dark sector particles could mediate the feeble interactions between dark matter and ordinary matter, mediate self-interactions within dark matter, or even be dark matter themselves. I will explore theories related to dark matter and dark sectors, as well as the ongoing searches for them through terrestrial experiments and astrophysical observations.

Aquatic Animal Virtopsy Lab - Health Assessment of Marine Tetrapods
海洋動物影像解剖研究組－當海豚遇上海龜？
Since 2014, our team has been applied a cutting-edge technique named ''virtopsy'' on local Cetacean Stranding Investigation. This technique was later extended to the research on stranded sea turtle since 2019. This technique enhances better understanding and gives insights into health conditions and life history of the stranded aquatic animals, and their injuries and deaths caused by human interactions. The collected data enables assessment of aquatic animals' health and provides an important reference to the development of a unique centralised database and long-term strategies for conservation of aquatic animals. Such a complete ecosystem indicator may eventually support the conservation and policy decision for all oceans, leading to an "One Ocean-One Health" paradigm.

自2014年起，我們研究組率先應用影像解剖在香港鯨豚擱淺調查的研究，並在2019年延伸至在本港擱淺的海龜。這種創新科技能協助研究人員進一步瞭解海洋動物的健康狀況、其生活史與及由人類活動所造成的損傷和死亡。這些資料有助評估動物健康情況，並可用以建立獨特的資料庫，以協助制定動物保育的長遠策略，以至為整個海洋生態制定保育措施與政策的生態系統指標，從而達至「海洋健康一體化」的目標。

CSI of the Cetaceans: Virtopsy and One Ocean One Health
鯨豚法醫：影像解剖與海洋健康一體化
Cetaceans (whales, dolphins and porpoises) are prime sentinel species because of their long life spans, long-term coastal residences, high trophic level diets, and unique fat storage that can serve as depots for anthropogenic toxins. Cetaceans may be exposed to environmental stressors such as chemical pollutants, harmful algal biotoxins, and emerging pathogens. Since many cetaceans share the coastal environment with humans and consume the same food, they also may serve as effective sentinels for public health concerns.

This talk aims to introduce a cutting-edge technique named ''virtopsy'', which has been applied on Cetacean Stranding Investigation in Hong Kong and adjacent waters since 2014. This technique enhances better understanding and gives insights into health conditions and life history of the stranded carcasses and their injuries and deaths caused by human interaction. The collected data allow measurement of cetacean health trends and provide an important reference to the development of a unique centralized database and long-term strategies for the conservation of local cetaceans. Such a complete ecosystem indicator may eventually not only benefit the cetaceans being studied, but also human health as well by keeping the entire marine environment healthy and supporting the conservation and policy decision for all oceans, leading to an ‘One Ocean−One Health’ paradigm using cetaceans as sentinels of potential emerging hazards.

Linking Human Health with Animal and Environmental Health
The COVID-19 pandemic has reminded us that despite all of our technological advances, our survival as human beings remains closely dependent on the health of the ecosystem in which we live. This is as true in urban as it is in rural areas. Humans are exposed to a wide variety of pathogens, most of them through direct or indirect contact with other humans, and some of them as a result of exposure to animals. The global human population is still growing rapidly, resulting in a continual demand for more land for humans to live on and to produce food. This situation provides new opportunities for transmitting infectious diseases from wild to domestic animals and to humans. This, together with the intense global interconnectedness through human travel and the food trade, allows for the rapid and potentially undetected spread of diseases. The aim of this talk is to examine the importance of the One Health approach in the context of human and animal disease control.

Extraction of Molecular Hydrogen from Wastewater
Molecular hydrogen (H2) is a clean energy carrier with high energy density. It is also a chemical reagent for petroleum refining as well as ammonia production. Currently, major production way is based on fossil fuel transformation, including the steam reformation of methane. Water splitting is another popular potential way in producing H2 with low or zero carbon footprint but water decomposition is a thermodynamically challenging reaction. Wastewater containing organic pollutants such as pharmaceutical wastewater, leachate, and industrial process water, on the other hand, can be potentially used to produce H2 with reduced energy requirement during the oxidative removal of such organic carbon inherently present in the water stream. We examine a few potential methods to simultaneously oxidise the organic component (pollutant) in the water and reduce the proton to liberate molecular H2. In particular, electrocatalysis, photocatalysis and photoelectrocatalysis are developed. Challenges encountered in this waste-to-energy conversion process will be tackled.

UN Sustainable Development Goals (SDGs) and Ourselves
The Sustainable Development Goals (SDGs) are a collection of 17 interlinked global goals designed to be a “shared blueprint for peace and prosperity for people and the planet, now and into the future”. They were set up in 2015 by the UN general Assembly and are intended to be achieved by 2030. These goals look at the economic development, innovation, environment, justice, equality, life below water and on land, etc. They touch upon everyone’s life. Their achievement also depends on each one of us, the citizen of the plant. In this sharing, we’ll analyze the goals that affect People, Planet, Prosperity, Peace and Partnership. This talk will discuss about how we can do to help those SDGs to be achieved.

Urban Solar Photovoltaic Technologies
The Hong Kong government has set an ambitious goal of reaching carbon neutrality by 2050. A critical strategy in its overall planning is to increase the deployment of renewable solar energy. In this talk, the speaker will discuss how we can rely on technological innovation to tackle this grand challenge; particularly, we have identified a new generation of printable, flexible, transparent, and color-tunable solar cells as the most prominent photovoltaic technology to promote solar energy deployment in Hong Kong. Such a new solar cell technology can be integrated as tinted solar windows, façades, or curtains with buildings to generate significantly more solar electricity in an urban city, which usually has limited lands and rooftops for installing conventional silicon solar panels.

Urbanisation and Climate Change in Asia: Impacts and Adaptation
During the last 20 to 30 years, because of rapid economic growth, extensive areas of agricultural and rural land in many countries in Asia have been transformed into cities. Such changes have substantially modified the exchanges of atmospheric properties between the land surface and the atmosphere. In addition, these cities, many of which have been known as mega-cities, generate additional heat and pollutants that are injected into the atmosphere. Furthermore, many of these cities have been developed over a short period of time, and hence city planning in general has been minimal. All these consequences of urbanization have great impacts on the regional climate, which will also be affected by global climate change. Thus, cities in Asia have suffered, and will likely continue to suffer, significantly in terms of climate hazards.

In this talk, how urbanization and global climate change can modify the regional climate will first be presented using examples from the Pearl River Delta of China (including Hong Kong) and other mega-cities. The possible impacts of such climate hazards will then be discussed. Examples of actions taken by governments to reduce the consequences of such impacts will be presented.

What Controls the Formation and Movement of Tropical Cyclones?
Tropical cyclones, a global name of typhoons, are one of the most destructive natural disasters on Earth. Every year, around 85 tropical cyclones are formed in the tropical ocean, and they move to higher latitudes. Among them, more than 30% of tropical cyclones are formed in the western Pacific. In this talk, you will learn what controls the formation, movement, and destructiveness of tropical cyclones.
