Research Stories
Edge-breaking research efforts by faculty members from the College of Science (CSCI) contributed in achieving the UN’s Sustainable Development Goals.
Face masks have become an important tool in fighting against the COVID-19 pandemic. However, improper use or disposal of masks may lead to “secondary transmission”. A research team from City University of Hong Kong (CityU) has successfully produced graphene masks with an anti-bacterial efficiency of 80%, which can be enhanced to almost 100% with exposure to sunlight for around 10 minutes.
Four outstanding scholars from City University of Hong Kong (CityU) have been selected as awardees of the inaugural Senior Research Fellow Scheme (SRFS) and Research Fellow Scheme (RFS) under the Research Grants Council (RGC), being granted a sum of more than HK$23 million as research funding. The acknowledgement of their research achievements is testimony to CityU’s research strengths and recognition of the University’s efforts in fostering interdisciplinary research.
Recently, with the state-of-the-art neutron scattering instrumentation and molecular dynamic simulations, an international research team, led by physicists from City University of Hong Kong (CityU), has demonstrated the existence of high-frequency transverse phonons in metallic glass for the first time. Their findings also suggest that the atomic structure correlates with its atomic dynamics, providing new insight for understanding the atomic structure-dynamics relationship in disordered materials.
Lead halide perovskite semiconductors exhibit superb optoelectronic properties and have been broadly applied in research fields like solar cells, photoelectric sensors and laser devices. However, the weakness of easy degradation in water hinders the application of perovskite semiconductors. A research team led by scientists from City University of Hong Kong (CityU) has developed a novel synthesis method of perovskite materials to overcome this problem.
In the era of smart cities and amid the global outbreak of Covid-19, connecting through the internet is getting more important than ever. Researchers have been working day and night on advancing the optical data transmission network to address the demand for faster transmission speed. An international research team has developed a new technology that is equipped with a special chip made by a scientist from City University of Hong Kong (CityU). The team broke the spectral efficiency world record for optical data transmission with a single integrated photonic chip. This allows the transmission speed as fast as downloading 1,000 high-definition movies in less than a second!
A team comprising researchers from City University of Hong Kong (CityU) has developed an anode material for lithium batteries with fast charging and discharging capabilities, which may significantly shorten the charging time for electric vehicles from half-hour to just three to six minutes.
