On November 20, 2025, an undergraduate team from the School of Chemistry and Chemical Engineering at Shaanxi Normal University won the first prize at the 2025 Shaanxi Provincial Science Experiment Exhibition Competition with their project titled “Leave ‘dangerous elements’ nowhere to hide”.

Under the guidance of R&D engineer Luo Yanyan, five students—Zheng Ruiying, Tian Yiping, and others—meticulously designed and choreographed their presentation, and vividly demonstrated the working principles of film-based fluorescent sensors, ingeniously transforming the experimental process into a mini-stage play. This allowed the audience to witness firsthand how fluorescent sensors reveal the presence of “dangerous elements” such as TNT, hexogen, and trinitrotoluene.

This competition was jointly organized by the Shaanxi Provincial Department of Science and Technology, the Shaanxi Provincial Department of Education, and the Shaanxi Association for Science and Technology. It aimed to promote the spirit of scientists and enhance the scientific literacy of the general public. Since the preliminary round commenced on July 31, the event attracted 100 projects from across the province, from which thirty projects advanced to the finals, with five ultimately winning first prizes.
