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.

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.

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.

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.

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.

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.<br />

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.
