Professor Jin Shang’s Project Wins Gold at Silicon Valley Invention Festival 2025

The School of Energy and Environment (SEE) at City University of Hong Kong is proud to announce that the project “Portable and Self-cleaning Nitric Oxide Generator”, led by Associate Professor Jin Shang, has been awarded a Gold Medal at the prestigious Silicon Valley International Invention Festival (SVIIF) 2025.

Held at the Santa Clara Convention Center in California, SVIIF is a global platform showcasing cutting-edge innovations across disciplines. CityUHK teams earned a total of 12 medals, including 3 Special Prizes, 7 Golds, and 2 Silvers, with SEE contributing one of the standout gold-winning entries.

Prof. Shang’s team developed a compact handheld inhaled nitric oxide (iNO) device that delivers on-demand, stable NO for over 30 hours using just 0.4g of material. The reactor converts powdered material and water mist into therapeutic nitric oxide at a cost of less than US$0.10 per treatment. A photocatalytic fabric filter at the outlet traps particles and kills pathogens, ensuring safe and clean NO delivery.

SEE congratulates Prof. Shang and his team for their outstanding achievement and contribution to global healthcare innovation. Their success reflects SEE’s commitment to pioneering research and impactful solutions for a sustainable future.
