Research Stories
Edge-breaking research efforts by faculty members from the College of Science (CSCI) contributed in achieving the UN’s Sustainable Development Goals.
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.
To protect the marine ecological environment and facilitate the sustainable development of the marine economy in Hong Kong, a CityU-led marine research team has developed a new aquaculture technique by establishing a floating, indoor weatherproof fish farm with a seawater recirculating system to replace conventional fish rafts.
A joint research team co-led by a scientist from City University of Hong Kong (CityU) has developed a much more stable, manganese-based cathode material. The new material has higher capacity and is more durable than the existing cobalt and nickel cathode materials - 90% of capacity is retained even when the number of charging-recharging cycles doubled.
A joint-study led by a team of marine ecologists from City University of Hong Kong (CityU) has found that the eco-engineered tiles can increase habitat complexity on seawalls in Hong Kong, thereby effectively enhancing the marine biodiversity. The Hong Kong study is part of a global research project on the relationship between habitat complexity and marine biodiversity on human-built marine structures.
While the power conversion efficiency of perovskite solar cells (PVSCs) – a future of solar cells – has already greatly improved in the past decade, the problems of instability and potential environmental impact are yet to be overcome. Recently, scientists from City University of Hong Kong (CityU) have developed a novel method which can simultaneously tackle the leakage of lead from PVSCs and the stability issue without compromising efficiency, paving the way for real-life application of perovskite photovoltaic technology.
