报告人简介：Xiaodong Zou is a full professor and chair of the Inorganic and Structural Chemistry Unit and deputy head of the Department of Materials and Environmental Chemistry, Stockholm University. She received her Bachelor of Science in Physics 1984 at Peking University and Master of Science in Metal Physics 1986 at Beijing University of Technology, under the supervision of Prof. K.H. Kuo. In 1987 she moved to Sweden to pursue her Ph.D. study and received her PhD in structural chemistry at Stockholm University in 1995. She carried out her postdoctoral research at Lund University, working with the Tage Erlander Professor David R. Veblen from John Hopkins University, USA. She joined the faculty at Stockholm University in 1996 and became professor 2005.
One of her main research interests is method development for accurate atomic structure determination of nano-sized crystals by electron crystallography. Her group has solved a number of complex structures of zeolites and mesoporous crystals by transmission electron microscopy. She is also working on synthesis, structure determination, topology analysis and applications of inorganic open-framework materials and metal-organic frameworks. In 2006, she received 100 MSEK from VR and VINNOVA to build up the Berzelii Center EXSELENT on Porous Materials and was the director 2006-2012. She has > 230 publications and four patents. Her group developed 9 software for quantitative analysis of high-resolution electron microscopy images and electron diffraction patterns. The software has been commecialized and used by > 200 laboratories.
She received several awards including Tage Erlander Prize for Science and Technology 2002 and Göran Gustafsson Prize in Chemistry 2008, both given by the Royal Swedish Academy of Sciences, the K.H. Kuo Award for Distinguished Scientist 2010 and the Arrhenius medal 2012 given by the Swedish Chemical Society. She is the fellow of the Royal Chemical Society (FRCS), the council member of the International Zeolite Association and the member of Structure Commission of International Zeolite Association.
报告简介： Knowing the structures of porous materials is essential for understanding the properties and predicting the applications of the materials. Transmission electron microscopy (TEM) and electron diffraction (ED) are among the most powerful techniques for studying crystals too small to be studied by single crystal X-ray diffraction or too complex to be studied by powder X-ray diffraction (PXRD). A major drawback is that each TEM image or ED pattern contains only 2D information (projection) of the material. Our group has been worksing on deveoping methods for collection and processing of 3D electron diffraction data and 3D reconstruction from high resolution electron microscopic images. Electron tomography (ET) can be used for studying the mesostructures. I will demonstrate the 3D rotation electron diffraction (RED) method for structure determination of unknown zeolites and metal-organic frameworks. I will show how RED data initiated the development of a novel approach that combines structure solution with structure prediction, and inspires subsequent targeted synthesis of new super-complex zeolites. Finally, we demonstrate the combination of RED and electron tomography for studying mesostructured structures.
