On May 21 and 22, 2025, Prof. Bian Hongtao of the Institute of New Concept Sensors and Molecular Materials participated in the User Meeting of the Large-scale Experimental Device for Tunable Infrared Laser-based Energy Chemistry Research in Hefei and presented an invited report titled “Ultrafast Vibrational Dynamics of Hydrogen-Bonded Networks in Confined Environments”.

Hefei Infrared Free Electron Laser Device is a special project for the development of national major scientific research instruments and equipment jointly undertaken by Xiamen University, University of Science and Technology of China, Fudan University and Dalian Institute of Chemical Physics, Chinese Academy of Sciences. This large-scale device contains a set of tunable infrared free-electron laser light source, a beam transmission line and five experimental line stations for energy chemistry research, which is the first free-electron laser user device covering the mid- and far-infrared wavelengths in China, and also the first infrared free-electron laser device for energy chemistry research in the world.

This meeting, chaired by Academician Sun Shigang of Xiamen University, aims to discuss how to make full use of the Hefei Infrared Free-Electron Laser Device to carry out high-level research and promote the joint development of the facility and its users.
