Research Stories

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.

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.

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.

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.
