CityU’s 3T MRI animal scanner
Diagnosis of Alzheimer’s disease, the most common type of dementia, is not easy for its overlapping signs with normal ageing. A collaborative research by City University of Hong Kong (CityU) and Johns Hopkins University has developed a new non-invasive molecular imaging approach based on Magnetic Resonance Imaging (MRI) to dynamically measure glucose level changes in the brain lymphatic system. Their discovery may help in identifying Alzheimer’s disease at early stages so that treatments can start as soon as possible.
Professor Samuel Ho, Associate Dean (Faculty and Research) of College of Liberal Arts and Social Sciences, and Professor of Psychology at Department of Social and Behavioural Sciences at City University of Hong Kong (CityU), has been researching on factors that facilitate people’s psychological adjustments to traumatic events. One of his research includes tracing medical staff and recovered patients of the 2003 SARS outbreak. Based on theoretical and empirical studies, he has developed an in-depth knowledge of increasing self-efficacy and fostering positive emotions, which can help cope with the stress brought by Covid-19.
Knot type to be identified by AI
AlphaGo, the artificial intelligence programme that plays chess, has made history by defeating two human world champions from China and South Korea. AlphaGo’s impressive victory over the sophisticated human brains is considered one giant step for artificial intelligence. Its “intelligence” is built from neural networks, a machine learning technology. Recently, scientists from City University of Hong Kong (CityU) and his collaborators have trained artificial neural networks to classify knots, achieving an accuracy of over 99%. It proves that machine learning can facilitate knot research in mathematical and physical sciences.
Schematic diagram_in vivo priming
A stem cell biologist from CityU, together with his collaborators, has developed a novel strategy, called in vivo priming, to “train” the stem cells to stay strong after implantation to the damaged heart via the 3D-printed bandage-like patch.
An international research team led by scientists from City University of Hong Kong (CityU) has recently discovered that high-entropy alloys (HEAs) exhibit exceptional mechanical properties at ultra-low temperatures due to the coexistence of multiple deformation mechanisms. Their discovery may hold the key to design new structural materials for applications at low temperatures.
Nanostructured Ag electrode
Plasmonics has drawn a lot of researchers’ attention for its huge application potential in enhanced spectroscopy (a way to obtain structural information down to even the single-molecule level), photothermal therapy, photoelectrocatalysis, photovoltaic devices, sensing, and optical waveguide. Recently, a research team led by scientists from City University of Hong Kong (CityU) has identified a novel way to decouple and quantify the thermal and non-thermal effects shown in plasmon-mediated chemical reactions. The team could even control the two effects precisely, which is important for designing and optimizing plasmonic devices and promote their applications.
Professor Alex Jen Kwan-yue, CityU
All-inorganic perovskite solar cells have drawn increasing attention because of their outstanding thermal stability. A research team led by scholars from City University of Hong Kong (CityU) has recently developed a new type of all-inorganic inverted perovskite solar cell through passivation.
Dr Ivan Borzenets, Kondo cloud
Physicists have been trying to observe the quantum phenomenon Kondo cloud for many decades. An international research team comprising a scientist from City University of Hong Kong (CityU) has recently developed a novel device that successfully measures the length of the Kondo cloud and even allows for controlling the Kondo cloud.
Dr Lu Yang
Graphene, also known as the “black gold”, is the thinnest material in the world with just a single layer of carbon atoms. Not only cannot be seen with the naked eye, but it is also extremely difficult for scientists to test the actual mechanical properties of free-standing graphene. A research team comprising scientists from City University of Hong Kong (CityU) and Tsinghua University has achieved a breakthrough in this aspect.
Professor He,novel photoelectrochemical system
Researchers from the City University of Hong Kong (CityU) and King Abdullah University of Science and Technology have joined hands and successfully developed a novel photoelectrochemical system, which can greatly improve the solar-to-hydrogen conversion efficiency from 3% to nearly 9%. It is more stable, with stability lasting for over 150 hours, highest among its counterparts. And its cost is 50% lower.
