A new system for testing food safety developed by an interdisciplinary research team at City University of Hong Kong (CityU) can rapidly detect contaminants in food in ten minutes with concentrations of less than 0.2ppm (parts per million).

The 14th International Conference on Nanostructured Materials (NANO 2018) was successfully held from 24 to 29 June at City University of Hong Kong (CityU), with about 600 international scholars and researchers famous in nanotechnology fields, coming from 35 countries/regions and 300 different research organisations.

It is well-known that sound wave carries dynamical phase during propagation. A latest research conducted by researcher from City University of Hong Kong (CityU) and his collaborators from other universities has demonstrated a new type of phase of sound: the spin-redirection geometric phase.

A research team led by Professor Paul Chu Kim-ho, a materials engineering expert at City University of Hong Kong (CityU), has developed a capacitive coating that kills bacteria when it is charged with electricity. When applied to orthopedic implants such as artificial joints and dental implants, the novel technology can reduce the risk of infection after surgery and help patients recover more quickly.
