It was a fruitful harvest for Hong Kong Baptist University research teams as four of their inventions received honors at the Geneva International Exhibition of Inventions.
The team led by the chair professor of the Department of Physics, Cheah Kok-wai, has won the gold medal with congratulations of the jury with an "anti-scratch thin film coating on metal surface."
The coat on a metal surface would add value to metal-based products such as watch cases and straps as it increases surface wear resistance without sacrificing the original appearance, said the researchers.
Two other inventions that received gold medals were a new virus-targeted therapy that specifically kills cancer cells without affecting any normal cells, and a quality control marker used in herbs authentication.
Another research team from the Department of Physics also received a silver medal for developing a portable body motion analyzer for assessing the risk of an elderly person falling.
