Can you imagine sound travels in the same way as light does? A research team at City University of Hong Kong (CityU) discovered a new type of sound wave: the airborne sound wave vibrates transversely and carries both spin and orbital angular momentum like light does.

a City University of Hong Kong (CityU) physicist observed the first unpaired singular Weyl magnetic monopole in a specific kind of single crystalline solid.

The State Key Laboratory of Marine Pollution (SKLMP) at City University of Hong Kong (CityU) has been endorsed by the United Nations (UN) to initiate a ten-year "Global Estuaries Monitoring (GEM)" Programme (www.globalestuaries.org) to collect and study environmental pollutants in the estuaries of major cities around the globe so as to formulate a long-term policy of promoting clean estuaries.

City University of Hong Kong (CityU) encourages research and innovation. By translating new knowledge and discoveries into applications, CityU contributes to the development of society.

A collaborative research team led by scientists from the City University of Hong Kong (CityU) recently overcame the barrier by developing a novel synthesis technique that combines the advantages of closed-system preparation of precursors and gas-solid reaction to produce a number of high-quality and pure unconventional metastable TMD materials in large quantities.

Glass is one of the most common subjects we see every day, but the detailed structure of this non-metallic and non-liquid material has always been a major mystery in science. A research team co-led by scientists at City University of Hong Kong (CityU) has successfully discovered that the amorphous and crystalline metallic glass have the same structural building blocks.
