A Study of Bacteria Emission from Toilet Flushing
The flushing of toilets generates contaminated aerosols, which may cause the spread of disease through the transmission especially during outbreak of epidemic such as COVID19. In this work, the emission strength by a single flushing was measured. Two common flushing systems and 4 bacteria were tested.
According to the research, the emission strength becomes stronger when water pressure level is higher and emission rate can rise higher when the bacterial size is smaller. It is important to maintain good hygiene in toilets to minimize the infection risk.

Innovative Imaging Technology to Detect Early Stages of Alzheimer’s Disease
Over 50 million people suffer from dementia globally, and more than 10 million new cases reported per year. The youngest patient is 23 years old. Early diagnosis is the key to fight dementia, which enables early interventions to slow down the progression of the disease. Notably, Alzheimer’s disease (AD) is the most common form of dementia. Dr. Chan and her team have discovered a new imaging technology that makes use of natural D-glucose (a type of sugar) and MRI to detect AD at early stages. This new imaging technology is non-invasive and sensitive to detect changes in the levels of glucose in the brain, which could provide early clues about the disease and help patients to get the necessary treatments around 10-20 years before symptoms appear.

Modeling the Nervous System from its Electrical Signal Transmission
In the last decade, we have witnessed astounding technical advances for recording and manipulating electrical activities of the nervous system. Our project focuses on the computational models of biological neural circuits, which provides solutions for reverse-engineering neural interconnections and better understanding on how the brain works. It also helps develop smarter machine learning algorithms capable of lifelong learning and building next-generation neural prostheses, human-computer interface and assistive devices to restore functions damaged by diseases or injuries for patients.

High-performance Water Kinetic Energy Harvesting Technology
In this project, a new type of droplet generator (DEG) with FET-like structure is proposed. Due to the synergistic effect between the high charge density induced by the droplet impinging the PTFE surface and the unique FET-like structure design, this droplet generator successfully breaks the bottleneck of low power generation efficiency in the conventional design. The instantaneous power can reach 50 watts per square meter, which is thousands of times higher than the conventional droplet generators.

Study on Immersion Cooling System for Data Center
Data centres usually operate 24/7 all year round and they are highly electricity consuming. Significant electricity consumption is attributed to the cooling equipment. With the proliferation of data centres in Hong Kong, it is increasingly important to promote energy efficiency of data centres. To minimize the cooling energy use in data centres, it is essential to explore innovative energy efficient cooling system for data centres. Immersion cooling system is an emerging energy efficient technology for cooling the servers by immersing them in electrically non-conductive but thermally conductive liquid. The project is proposed to carry out a systematic study on the immersion cooling system to evaluate its energy efficiency and reliability in a Hong Kong typical data center.
• 8 Live interactive STEM Workshops conducted by our teachers.
Visualizing Wireless Communication
In this workshop we will introduce the basics of electromagnetic waves, and briefly talk about their involvement in 1G - 5G cellular and various other forms of wireless communications. We will then build a simple device that allows us to visualize the signals involved in wireless communication.
Low Carbon Energy Education Centre Lego Workshop
Wind power is one of the most commonly used renewable energy sources.
CityU's CLP Power Low Carbon Energy Education Centre (LCEEC) offers visitors an inspiring and enlightening experience to learn about the importance of low carbon energy to address the environmental challenges we face.
The workshop is divided into 2 parts. In the first part, participants will join a virtual guided tour in LCEEC to learn about the low carbon energy application in Hong Kong and the reasons of using a diversified and low carbon fuel mix.
In the second part, participants will use Megabricks, an online platform to stimulate building up a wind turbine model with LEGO. They will learn about the electricity generation principle, the advantages and limitations of wind energy.
Heat Flows from Cold to Hot Locations. Are We Breaking the Law of Physics?
Explaining the Construction and Operating Principle of an Air-conditioner.
According to the law of physics, heat flows from hot to cold locations. In an air-conditioned room during summer season, heat energy is transferred from the indoor space at a lower temperature (e.g. at 25°C) to the outdoor space at a higher temperature (e.g. 30°C), in order to achieve an indoor thermally comfortable condition. It seems that it is against the law of physics. In this workshop, the basic construction and operating principle of an air-conditioner will be explained.
根據物理定律, 熱量是從高溫流到低溫的地方。在一個處於夏季的空調房間中, 熱能是從較低溫度的室內（例如25°C）, 傳到較高溫度的室外空間（例如30°C）, 以達到室內熱舒適的狀態。看似是違反了物理定律。在這個工作坊中，將會詳細解釋冷氣機的基本構造, 和運作原理。
