Fast-moving excitons observed for first time in metal, unlocking potential to speed up digital communication
18 Mar 2022
In a world first, a team co-led by a physicist at City University of Hong Kong (CityU) has discovered that excitons—excited electrons bound to empty electron “holes”—can exist stably and travel rapidly through metal.
Nanofiber-based biodegradable millirobot that can release different drugs in targeted positions in the intestines
10 Mar 2022
A nanofiber-based biodegradable millirobot, called “Fibot”, was successfully developed in research led by a scholar from City University of Hong Kong (CityU). Fibot can move in the intestines and degrade in response to the pH of its environment, thus releasing different drugs in different anchored positions.
CityU scholars participate in a global study that reveals broad contamination of pharmaceuticals in the world’s rivers
03 Mar 2022
A recent global study, with the participation of scholars from City University of Hong Kong (CityU), found broad contamination of common pharmaceuticals in many of the world’s rivers, including two Hong Kong rivers: the Kai Tak River and the Lam Tsuen River.
Taking Engineering Research to New Heights for Wider Social Benefits
25 Feb 2022
Engineering bridges the gap between theory and practice by applying science and mathematics to turn discoveries into new innovations and technologies that are applicable to everyday life.
Robotic VR system to teleoperate robots with potential for Covid-19 swab tests and other tasks
21 Feb 2022
A research team co-led by City University of Hong Kong (CityU) and collaborating institution recently developed an innovative HMI system, which consists of flexible, multi-layered electronic skin and provides both visual and haptic feedback to users.
CityU research estimates vaccine donation from high to low- and middle-income countries will help end COVID-19 pandemic
17 Feb 2022
COVID-19 vaccines give hope in ending the pandemic, yet they are unequally distributed globally. Infection and mortality rates for COVID-19 in low- and middle-income countries could be significantly reduced if high-income countries donated 46% to 80% of their COVID-19 vaccine stocks to them.
Four CityU Projects Awarded HK$20 Million from Green Tech Fund
10 Feb 2022
Four research projects led by scholars at City University of Hong Kong (CityU) received grants worth HK$20.26 million in total from the inaugural Green Tech Fund under the Environmental Protection Department, Hong Kong SAR Government.
Super-elastic High-Entropy Elinvar Alloy Discovered with Potential for Aerospace Engineering
10 Feb 2022
Metals usually soften when they expand under heating, but a research team led by a City University of Hong Kong (CityU) scholar and other researchers have discovered a first-of-its-kind super-elastic alloy that can retain its stiffness even after being heated to 1,000K (about 727℃) or above , with nearly zero energy dissipation.
A new structured thermal armour achieves liquid cooling above 1,000°C, overcoming challenge of Leidenfrost effect
27 Jan 2022
A research team led by scientists from City University of Hong Kong (CityU) has recently designed a structured thermal armour (STA) that achieves efficient liquid cooling even over 1,000°C, fundamentally solving a 266-year-old challenge presented by the Leidenfrost effect.
Novel Double Helix Yarn Piezoresistive Sensor for Pulse Monitoring
20 Jan 2022
Textiles woven with yarn are used in remote medical diagnosis with intelligent electronic sensing technology. However, the derived inconsistent signals are one of the problems yet to be solved. A research led by a scholar from City University of Hong Kong (CityU) was inspired by the structure of DNA and found that textiles woven with double helix structure can help overcome the said challenge.
