On November 22, 2025, the 15th National Particle Testing Academic Conference and the 2025 National Powder Testing Technology Application Seminar opened in Foshan City, Guangdong Province. This conference is jointly organized by the Particle Testing Professional Committee of the Chinese Particle Society and the Beijing Powder Technology Association. The Particle Testing Professional Committee of the Chinese Particle Society is a subsidiary of the Chinese Particle Society, established in 1986. The Particle Testing Professional Committee focuses on theoretical research, instrument development, and standard setting in the field of particle testing. Jinan Weina actively participated in the work and construction of the society in the last century and is an important member unit of the society. This conference coincides with the 40th anniversary of the establishment of the special committee, bringing together top experts, young scholars, corporate elites, and industry partners in the field of particle testing and powder technology from across the country. Mr. Ren Fei, a member of the Chinese Particle Society special committee and chairman of Jinan Micro Nano Particle Co., Ltd., was invited to attend the conference and received individual and collective awards from the society.

After forty years of development and precipitation, China's particle testing technology has achieved a revolutionary leap from macro to micro, from offline to online monitoring in the laboratory, and from single parameter to multi-dimensional intelligent analysis. The technology inheritance of micro/nano particle testing technology has been since 1982, when it undertook the national key scientific and technological project of the Seventh Five Year Plan. Now, the laser particle sizer, nano particle sizer, particle image analyzer, spray particle sizer, online particle size monitor and other series have occupied the domestic market share and entered the international market. They have personally experienced and jointly witnessed the development and prosperity of China's particle testing industry.

During the meeting, Mr. Ren Fei, Chairman of Micro Nano Particles, served as the moderator and presented certificates to the conference speaker. The future is here, passed down from generation to generation. The particle industry has been developing through continuous progress and innovation. Micro and nano particles are witnesses and drivers of the development of the particle testing industry, and they are also companions of all particle colleagues born into the "new".

Small particles contain great energy, but despite their small size, they are the wings of China's development of new quality productivity - new energy batteries, high-end biomedicine, semiconductor chips, aerospace composite materials Almost all core materials of strategic emerging industries cannot be separated from the precise characterization and regulation of particles; Micro nano particles are willing to develop together with all colleagues in particle testing, witness the magnificent transformation of China's particle testing technology from "parallel running" to "leading", and once again participate in the next conference.
