From December 5 to 7, 2024, the "Seminar on Sensor-driven Surface and Interface Science and Photophysical Technology Application", sponsored by the Chemical Science Department of National Natural Science Foundation of China and hosted by the School of Chemistry and Chemical Engineering of Shaanxi Normal University and the Institute of Frontier Science and Technology of Xi'an Jiaotong University, was held in Xi'an City. Nearly 80 experts and scholars from China, the United Kingdom and teachers from Shaanxi Normal University and Xi'an Jiaotong University attended the conference.

The opening ceremony of the seminar was presided over by SNNU Science and Technology Department director and SCCE dean Prof. Xue Dong. At the opening ceremony, SNNU vice president Prof. Yang Zupei and XJTU vice president Prof. Shan Zhiwei delivered speeches respectively, welcoming the guests and scholars and wishing the conference a complete success.

At the opening ceremony, Gao Feixue, director of NSFC Chemical Science Department, gave a speech explaining the application, funding and policy changes of various fund projects in recent years, and emphasized the core issues that should be focused on during the discussion of this meeting.

The subsequent academic reports covered the basic and application development of surface and interface chemistry and the important research progress from different perspectives and fields, with rich content and heated discussions, including “The True Road to Dynamic Chemistry” by CAS Academician Tian He of East China University of Science and Technology, “Biomimetic Micro-nano Structure and Its Application” by Prof. Yuan Weizheng of Northwestern Polytechnical University, “Interface Wetting and Fluid Micro-nano Manufacturing” by Prof. Shao Jinyou of Xi’an Jiaotong University, “Research on Micro-Nano Fiber Interferometer Sensor and Its Application” by A/Prof. Qiang Wu of Northumbria University, UK, “Research and Application of High-performance Sensing Films” by Research Feng Liang of CAS Dalian Institute of Chemical Physics, “Reflections on Surface and Interface Problems of Bulk Single Crystal Growth and Device Preparation for Nuclear Radiation Detection” by Prof. Xu Yadong of Northwestern Polytechnical University, “Kinetic Studies on Solvation and Symmetry-breaking Charge Transfer Induced by Excited State Conformation” by Prof. Xia Andong of Beijing University of Posts and Telecommunications, “Excited States and Non-adiabatic Processes” by Prof. Cui Ganglong of Beijing Normal University,  “Mechanism of Surface Charge Influence on Solid-liquid Interface Interactions” by Researcher Deng Xu of University of Electronic Science and Technology of China, “Internal Surface Sensitive Microporous Gas Sensing Materials” by Researcher Xu Gang of CAS Fujian Institute of Material Structure, “Strongly-confined and Weakly-confined Semiconductor Nanocrystals: Photon (exciton) Manipulation” by Prof. Peng Xiaogang of Zhejiang University, “Molecular-scale Modeling Analysis and Prediction of Surface Infiltration” by Prof. Wang Dayang of Jilin University, and “Construction of Multi-scale Intelligent Soft Matter Systems” by Researcher Liu Minghua of CAS Institute of Chemistry.
