The 15th National Social Practice and Science Competition on Energy Conservation & Emission Reduction for College Students (hereinafter referred to as the Competition) was concluded at Tianjin University in August. Eight projects of Shenzhen Technology University (SZTU) reached the final. It was the third time SZTU had taken part in the Competition and students won three national second prizes and two national third prizes this year, making great progress compared with the past two years.

The Competition is an important science and technology innovation contest for college students organized by the Department of Higher Education of Ministry of Education, which coincides with the national policies of energy conservation and emission reduction. This year, a total of 46,139 students from 623 higher education institutions participated in the Competition with 5,373 projects. Organized by the College of New Materials and New Energies and Julong College, the school-level competition of SZTU was held in May and selected nine projects to enter the final. To better help students prepare for the final competition, Julong College arranged tutorial supervision and mock presentation during the summer vacation.

 

List of winners

National second prize

1. Dual loop drying system based on the combination of optothermal and air energy

Team members: Liu Lijie, Yue Jianglong, Wei Daqi, Wu Mingen, Lu Haopei, Yang Ziyue, Huang Baiming

The device can not only reduce the cost of hydrogen production by using waste photoelectricity to electrolyze water to produce hydrogen but also improve the electrochemical active specific surface area (ECSA) by using lattice-like porous electrodes prepared by additive manufacturing technology.

National third prize

1. A self-powered and self-aware pseudo 3D projection intelligent traffic marking system

Team members: Zhou Le, Yang Zikai, Wen Zhihao, Zhu Junwei, Huang Kangdong

Instructors: Yin Xiaohong, Wang Yanyan

College: College of Urban Transportation and Logistics
