On April 29th, the College of Mathematics and Physics successfully held the ninth session of the "Xishu·Wuli" high-level academic lecture series at the Lixue Lecture Hall on the Changping Campus. The event featured an academic report by Professor Wang Rongming from the University of Science and Technology Beijing, titled "From Nucleation Pathways to Interface Design: Atomic-Scale Mechanisms of Material Formation." The report was presided over by Wang Wei, Dean of the College of Mathematics and Physics, with nearly 200 teachers and students from the Changping Campus in attendance.

Professor Wang Rongming's report focused on the cutting-edge scientific issues of atomic-scale interfacial dynamics and the controllable preparation of nanomaterials, centering on the core question of "how interfaces form and how they determine material properties." Based on in-situ environmental transmission electron microscopy (ETEM) and a multi-physics coupled experimental platform, he systematically developed atomic-scale dynamic characterization methods for nanomaterials under real reaction environments, achieving direct observations of single-atom diffusion, non-classical nucleation pathways, and interfacial structural evolution processes.

This lecture unveiled the multi-step nucleation mechanism in two-dimensional materials and metal/2D semiconductor heterostructures, involving the pathway from amorphous clusters to a 2D amorphous intermediate state and then to crystallization. It also elucidated the intrinsic coupling relationship between interfacial atomic configurations and local electronic states. The related research provides new physical insights and methodological approaches for the predictable design of interfacial structures in micro/nano devices and catalytic systems. During the interactive session, Professor Wang Rongming engaged in a lively discussion with the attending faculty and students on topics such as interfacial structure research, and patiently answered their questions.

the "Xishu·Wuli" high-level academic lecture series remains committed to building a high-level platform for academic exchange. It aims to help teachers and students stay abreast of disciplinary developments, enhance their research literacy and forward-looking capabilities, and drive talent cultivation and scientific innovation through cutting-edge achievements.
