In the Student Culture Activity Center, March 21, the 17^th Climbing Cup, the Science and Technology Competition Final came to an end successfully. From the beginning of the competition, it had received extensive attention and active participation from all the teachers and students and 373 teams took part. After polishing the project for nearly half a year, more than one hundred teams advanced to the final. In the end, Feng Luqiao, the DLI 2019 Engineering student and her team won the Second Prize, Wu Changhao, the DLI 2019 Math student and his team won the third prize. Besides, Chen Runze, DLI 2017 student and Wang Daohan DLI 2018 student made a good contribution for their team to own prizes.

Feng Luqiao and her team focus on the deep-water plant lighting system. At present, deep-water plant lighting is generally used for underwater lamps about 5 meters, for 5 meters or deeper waters the lamp cannot withstand such strong pressure, wherein the lamp waterproof measures cannot meet the requirements, the existing shallow water lamps cannot be illuminated, not to mention 30 meters below the deep-water plant lighting system to achieve deep water lighting, if the use of shallow water plant lighting system, the effect is poor, and there are many defects cannot meet the deep-water plant lighting environment. In view of this, the purpose of this model is to provide a deep-water plant lighting system.

Wu Changhao and his team bend themselves to a specific APP named “To-Gather” which could provide a channel for a student to get together especially under the post-epidemic era. To-Gather aims at leveraging the Internet to gather university/college students in the same city who have the same social needs within the same period of time, performing online one-on-one matching based on the similarities of their interests and hobbies, and recommending suitable event locations and corresponding high-quality services. This will make more and more university students move out of their respective comfort zones and meet people with similar interests and hobbies in life, before sharing good moments together.

Chen Runze and his team are enthusiastic about making chemical research with special methods. The work obtaining the Climbing Cup is based on their research area. They used TiOx nanocomposite (YSA-PEG-TiOX) instead of TiO2 as a photosensitizer to solve the problem of insufficient ROS generation in PDT. Their findings showed that the modification of YSA peptide improved the cytotoxicity of YSA-PEG-TiOX/CTD to EphA2 overexpressing A549 non-small cell lung cancer (NSCLC) than non-YSA modified counterparts. In addition, TiOx generated adequate ROS under X-ray irradiation to further kill cancer cells. Flow analysis results also proved the superiority of this combined treatment.

Under the epidemic prevention and control, the competition system not only followed the usual practice of previous years to arrange the exhibition on the spot, but also held the closed presentation similar to the Challenge Cup. As for the judges, there were not only experts and scholars from various departments of the university, but also experts from the national innovation and entrepreneurship competition. All of these provided all-around challenges for projects and helped accumulate valuable experience for participating in the later national innovation and entrepreneurship competition.
