The 47th International Exhibition of Inventions, Geneva recently concluded. Nanjing University won the Special Gold Medal for its invention out of more than 800 competing submissions, making it the only one that received such an award among universities from Jiangsu Province. Besides, a number of gold medals were awarded to Nanjing University, Southeast University and Nanjing University of Aeronautics and Astronautics for their inventions.

The award-winning “Mobile Water Tank”, designed by Nanjing University in only the size of a laptop, amazed the audience for its function to purify sewage, seawater and bitter brine into drinking water. The full name of the project is “solar technology for water treatment based on nano black gold”. Its core technology is that solar energy is converted by special nano black gold material to desalinate seawater and treat high-salt wastewater.

In addition, Professor Xu Jinglei’s team from the College of Energy and Power Engineering, Nanjing University of Aeronautics and Astronautics won the gold medal for their “new multifunctional pneumatic vector nozzle” project. Professor Guo Tong and his team from Southeast University received the gold medal for their research finding entitled “seismic resilience-oriented friction-consuming auto-recovering anti-seismic structure”.
