CityU scholar estimates new Covid-19 cases in Hong Kong based on different quarantine conditions
25 Feb 2020
As the spread of the novel coronavirus (Covid-19) epidemic continued, the effectiveness of existing quarantine measures is one of the major concerns. An expert in mathematical modelling for infectious diseases at City University of Hong Kong (CityU) estimated that there was a 3.5-day time gap between patients showing Covid-19 symptoms and being quarantined in Hong Kong. And in this case, there will be a possible increase of around 60 infected cases from mid-February to mid-March.
CityU’s latest ranking results goes above and beyond
20 Feb 2020
City University of Hong Kong (CityU) aims at excelling in research and professional education, as well as promoting innovation. Faculty members are committed in research and innovations that support social, economic and technological advancement. CityU’s efforts are highly recognized, as reflected in the improvement in different rankings.
CityU young scholar’s research on rare cells brings hope to new cancer immunotherapy and vaccine
20 Feb 2020
Cancer immunotherapy has drawn increasing attention in recent years. Although still at its infancy, it has brought hope to many cancer patients. Exploring the anti-tumour activities of a rare immune cell type in the human body is the focus of a research project led by a biomedical scientist and her research team at City University of Hong Kong (CityU). The research findings will provide insights into designing new generations of cancer immunotherapy and vaccine against different cancers.
Potential spread of pathogens via aerosol droplets produced by toilet flushing
14 Feb 2020
Toilet hygiene has once again aroused public concern during the outbreak of the novel coronavirus epidemic. According to a study done by City University of Hong Kong (CityU), airborne aerosol droplets created in flushing might rise up to a metre if the toilet was not covered, and the pathogens embedded in the droplets can potentially spread and affect toilet users’ health.
CityU scholar researching on RNA awarded Croucher Innovation Awards 
13 Feb 2020
Protein and DNA (deoxyribonucleic acid) may sound familiar to everyone, but RNA (ribonucleic acid) is probably another story. In fact, RNA plays a pivotal role in many aspects, such as decoding the genetic codes stored in DNA and producing protein. Dr Kwok Chun Kit, Assistant Professor from the Department of Chemistry at City University of Hong Kong (CityU), is devoted to studying RNA. He hopes to reveal the structure of a specific type of RNA and its interactions in cells, as well as its biological functions and mechanism, in order to develop chemical and molecular tools for diagnostic and therapeutic applications. 
New droplet-based electricity generator: A drop of water generates 140V power, lighting up 100 LED bulbs
06 Feb 2020
Generating electricity from raindrops efficiently has gone one step further. A research team led by scientists from the City University of Hong Kong (CityU) has recently developed a droplet-based electricity generator (DEG), featured with a field-effect transistor (FET)-like structure that allows for high energy-conversion efficiency and instantaneous power density increased by thousands times compared to its counterparts without FET-like structure. This would help to advance scientific research of water energy generation and tackle the energy crisis.<br />
CityU research revealed the association between myelin formation and memory
09 Jan 2020
A study by City University of Hong Kong (CityU) reveals for the first time that schema-like learning can foster the growth and regeneration of brain myelin, thereby enhancing the learning and memory capacity. This has helped shed light on revealing the pathological mechanisms of central myelin diseases such as multiple sclerosis, cerebral ischemia, chronic recurrent pain, irritable bowel syndrome (IBS), severe depression and Alzheimer's disease. 
A new generation of nanostructured aluminium alloy with ultrahigh strength and large plasticity
19 Dec 2019
High strength and high ductility are often mutually exclusive properties for structural metallic materials. A recent study led by the City University of Hong Kong (CityU) revealed a new strategy to overcome this trade-off dilemma. Aided by molecular dynamics simulations, the research team developed a hierarchical nanostructured aluminium alloy composed of amorphous-nanocrystalline structures. This new aluminium alloy achieves the highest strength and high ductility of its kind so far. It can be applied to micro-electromechanical systems (MEMS) for flexible wearable devices in the future.<br />
Liquid-like behaviour displayed but phase remains stable in ultrathin hexagonal gold nanoribbons
12 Dec 2019
A recent research led by City University of Hong Kong (CityU) has discovered that the ultrathin gold nanoribbons with unique hexagonal (4H type) crystal phase shows “liquid-like” behaviour under heating, but its hexagonal crystalline structure remains stable. This provides insight into the thermal stability of this new type of metallic nanomaterials and facilitates the development of practical applications in the future.
A new supramolecular silicone coating: damage-healable, oil-repellent and adhesive to various materials
28 Nov 2019
A research project led by City University of Hong Kong (CityU) has invented a new supramolecular silicone (DOSS) coating with inherent damage-healing and oil-repellent properties which can be adhesive to various materials. The research team managed to overcome the existing materials’ limitations by molecular engineering. They envision that it can be utilized in self-cleaning, antifouling, catalysis, energy storage and heat transfer with broad applications in the energy, environmental, and biomedical aspects.<br />
