The 1st International Symposium on Non-equilibrium Transport Phenomena (NETP 2025) was successfully held in Beijing from April 7 to 10, 2025.

The symposium, jointly organized by the Chinese Society of Theoretical and Applied Mechanics (CSTAM) and the Institute of Mechanics, Chinese Academy of Sciences (IMECH, CAS), brought together over 200 distinguished researchers from 13 countries and regions. Representatives from Belgium, Canada, France, Germany, Iran, Japan, Russia, the Netherlands, Norway, the United Kingdom, the United States, Hong Kong, and the Chinese mainland, gathered to explore one of the most dynamic frontiers in science and engineering.

In their opening remarks, CSTAM President and Academician He Guowei and IMECH Director Professor Huang Heji extended a warm welcome to the international delegates. They emphasized the symposium's potential to advance scientific understanding and promote transformative innovations in the field.

The symposium's focus on non-equilibrium transport phenomena in fluid flows addresses one of the China Association for Science and Technology (CAST)'s 2024 Top 10 Science Challenges - "Understanding the transport mechanisms of multi-scale non-equilibrium flows." Professor Zhang Yonghao, co-chair of NETP 2025 and principal researcher at IMECH, CAS, presided over the opening ceremony. He emphasized ‌the pivotal role of advances in understanding non-equilibrium transport phenomena as a catalyst for breakthroughs‌ in energy efficiency, nanotechnology, space exploration, and related fields.

The event included an opening ceremony, 11 keynote lectures, 4 parallel sessions, poster presentations, and a technical visit, facilitating robust international academic exchange and collaboration.

Selected high-impact studies presented at NETP 2025 will be published in a special issue of CSTAM's flagship journal Acta Mechanica Sinica, titled "Multiscale Transport Mechanism of Non-equilibrium Flow", with Professor Xu Kun and Professor Zhong Chengwen serving as its Guest Editors.
