Biodiversity is of crucial importance to the marine ecosystem. The prohibition of trawling activities in the Hong Kong marine environment for two and a half years has significantly improved biodiversity, an inter-university study led by City University of Hong Kong (CityU) has found.

At CityU, an expert in neutron-scattering measurements has applied this state-of-the-art experimental technique to find out the deformation and transformation behaviours in complex materials, in particular at ultra-low temperatures, opening up a new area of materials research.

In the era of Artificial Intelligence (AI), a novel optical “micro-comb” chip developed by a physicist from the City University of Hong Kong (CityU) has played a pivotal role in building the fastest optical neural network processor. An international research team has recently demonstrated the world’s fastest and most powerful optical neural network processor, which is capable of operating at faster than 10 trillion operations per second.

At CityU, Professor Alex Jen Kwan-yue, Lee Shau-Kee Chair Professor of Materials Science, has been working on developing more stable and environmental friendly perovskite and organic solar cells, which are believed to offer more promising and diverse applications to replace silicon as the future of photovoltaic technology.

A team of multi-disciplinary experts, led by Professor Chi-hou Chan, Chair Professor in the Department of Electrical Engineering (EE) and Director of the State Key Laboratory of Terahertz and Millimeter Waves (SKLTMW) at CityU, has been working on advancing the development of terahertz (THz) technology for 6G communications, imaging and spectroscopy.

A research team from City University of Hong Kong (CityU) is the first team worldwide to routinely apply “virtopsy”, a pioneer dead body examination technique, on stranded cetaceans to find out their causes of death, health conditions, as well as the anthropogenic impact on their well-being.
