Professor Chunlin Jia of the Ernst Ruska-Centre (ER-C) is to receive the Hatsujiro Hashimoto Medal from the International Federation of Societies for Microscopy. The award, honouring the outstanding contributions of individual scientists in the application of microscopy and other related techniques in physics and material sciences, is named after the pioneer of microscopy research, Hatsujiro Hashimoto. Chunlin Jia will be presented with the prize in September at the 18th International Microscopy Congress in Prague.
The main focus of Chunlin Jia's work is on the investigation of electroceramic materials using advanced electron microscopy techniques, as well as in the development of new methods for the optimal use of so-called aberration-corrected transmission electron microscopy, which he employs in the course of his investigations. The NCSI (negative spherical aberration imaging) technique, which Chunlin Jia developed on the basis of the aberration-corrected microscope, has improved the visibility of lighter elements and has made it possible to determine the occupancies of individual atomic columns in crystalline materials. Employing the NCSI technique, Chunlin Jia has measured the interplay between structural and electron properties in nanomaterials by analysing image contrast quantitatively through comparisons with simulations. One of his most important contributions to materials science is his work on the atomic-scale characterisation of electric dipoles in oxide ferroelectrics. The orientation of the dipoles can be altered by applying an external electric field; such materials are therefore suitable for storing data in a very small amount of space.
Chunlin Jia has been group leader at the Institute of Microstructure Research and the Ernst Ruska-Centre since 1998. Since 2000, he has held professorships at various Chinese universities. In 1993, RWTH Aachen University awarded him the Borchers Medal, and the Chinese Electron Microscopy Society honoured him with the K.H. Kuo Award for outstanding scientists in 2004. In 2010, he was selected by the Chinese government to take part in the 1000 talents programme, which aims to offer the best scientists in the world the opportunity to conduct research in China Since then, Jia travels between Germany and China, where he has established an electron microscopy research platform at Jiaotong University in Xi'an.
