The recipient of 2017 Lee Hsun Lecture Series—Lee Hsun Lecture Award, Prof. Xiaoqing Pan from University of California at Irvine visited Institute of Metal Research, Chinese Academy of Sciences (IMR, CAS) from April 28 to May 2, 2018.

During the visit, Prof. Pan delivered a lecture entitled “Probing the Atomic Scale Structure and Dynamic Behaviors of Materials by Transmission Electron Microscopy”. In his lecture, he presented the work on the development of TEM techniques for imaging electric polarization and probing the nucleation and growth of ferroelectric domains and the interaction between domain walls and crystal defects during electric polarization switching. He also showed his study on the structures and dynamic evolution of catalysts under realistic conditions with atomic precision through a MEMS-based, electron-transparent closed cell with a heating stage.

Xiaoqing Pan is a professor and Henry Samueli Endowed Chair in Engineering, at UC Irvine in the Henry Samueli School of Engineering’s Department of Chemical Engineering & Materials Science and the School of Physical Sciences Department of Physics & Astronomy. He is also the inaugural director of the Irvine Materials Research Institute (IMRI).

Prof. Pan’s research interests focus on understanding the atomic-scale structure-property relationships of advanced functional materials, including oxide electronics, nanostructured ferroelectrics and multiferroics, and catalysts.

He is recognized internationally for his work in materials physics and electron microscopy that have led to the discovery of new properties and novel functionalities in technologically important materials. His pioneering contributions include the development of methods to quantitatively map the electrical polarization in ferroelectrics at atomic resolution, and methods to uncover the effects of boundary conditions on ferroelectricity, including polarization mapping, first observation of ferroelectric vortices, and dynamic behaviors of ferroelectric domains during electrical switching under applied electric field in TEM.

Prof. Pan has received many awards, including the National Science Foundation’s CAREER Award and the Chinese NSF’s Outstanding Young Investigator Award. Pan was elected to be a Fellow of the American Ceramic Society in 2011, a Fellow of the American Physical Society in 2013, and a Fellow of the Microscopy Society of America.
