From October 31st to November 2nd, 2025, the 15th National Aerosol Conference (15th NAC) was grandly held in Hangzhou. The conference was jointly organized by the Aerosol Committee of Chinese Society of Particuology and Xi’an Jiaotong University, and was hosted by Hangzhou International Innovation Institute of Beihang University and China Jiliang University. The conference attracted over 370 experts and scholars in the field of aerosols to exchange ideas on 13 major topics.
Palas® exhibited a variety of aerosol particle measurement instruments, providing systematic solutions covering particles ranging from nanometers to micrometers for the core topics of the conference such as “aerosol generation mechanisms, environmental effects, health impacts, monitoring technologies and control strategies”.
