On April 6, the 620th session of the Science & Engineering Lecture Series, along with the 47th Hongru Forum, was held in Lecture Hall 301 of the Conference Center. Xia Younan, a member of the National Academy of Engineering (NAE) and Professor at Johns Hopkins University, was invited to deliver an academic report titled Three Decades of Nanomaterials Research: From Fundamental Studies to Applications. Guan Jianguo, Deputy Director of the State Key Laboratory of Advanced Technology for Materials Synthesis and Processing, presided over the event.

Prof. Xia systematically summarized the development history of nanomaterials, from basic research to industrial applications, based on his 30 years of research and practice. In his report, he explained the controllable synthesis mechanism of nanomaterials and elaborated on the techniques used to precisely regulate their size, appearance, composition, and structure. He also gave a comprehensive analysis of structure-activity relationships in key fields, including surface plasmon, catalysis performance, nanomedicine, and regenerative medicine. A series of typical research achievements, such as photonic crystals, silver nanocrystals, gold nanocages, Janus nanoparticles, nanobottles, and electrospun nanofibers, were introduced in the speech. In addition, Prof. Xia highlighted the key breakthrough of the industrialization of core technologies, such as silver nanowires and radially aligned nanofibers, and drew lessons from this process, depicting the prospect of nanomaterials application for all present teachers and students.

During the interactive section, Prof. Xia had a deep dive with faculty and students into issues ranging from the synthesis mechanism of nanomaterials and structural regulation strategy to key challenges in industrialization. The event enjoyed a lively atmosphere, while faculty and students found the session highly rewarding.
