On 19–21 August 2023, the Monash Centre for Electron Microscopy (MCEM) hosted the Electron Crystallography School 2023 (ECS2023) as a satellite event to the 26th IUCr Congress. The School was organised by the IUCr Commission on Electron Crystallography, with Hongyi Xu, Tatiana Gorelik, Mauro Gemmi and Laure Bourgeois as co-chairs.

The ECS2023 focused on two broad topics that have seen considerable development in the last decade or so: 4D scanning transmission electron microscopy (4D-STEM) and 3D/micro-electron diffraction (3D-ED). These developments have led to major advances in the characterisation of the atomic-scale structure of solid matter, from energy materials and green chemicals to glasses, proteins and pharmaceutical compounds.

The School was aimed at postgraduate students, early-career researchers and newcomers to the field. It offered a series of lectures on the fundamental theory underpinning 4D-STEM and 3D-ED, together with historical background, software demonstrations and hands-on tutorials. The intensive program also included a live demonstration on MCEM’s latest transmission electron microscope acquisition, the Thermo Fisher Scientific Spectra-φ. A session was dedicated to presentations from industry scientists. There was also a lively poster session and a tour of MCEM facilities.

Cheng Zhao, Monash University, Australia

The electron crystallography school (ECS) was truly an unforgettable experience. It was the first time that I had met with academics and researchers that I had repeatedly read about in the literature and textbooks.

ECS was well organised from the very beginning to the end. The program included a variety of areas in electron microscopy/electron diffraction. As an electron microscopy student, I was amazed and inspired by the continuous exploration people had put into developing techniques and even building up their own equipment for certain experiments. I was also very interested in all the demonstrations on newly developed simulation techniques. The ‘new for me’ information on three-dimensional electron diffraction was also a very interesting aspect that I had never thought to be so useful before.

Another point that made this school so different was that it started with very fundamental knowledge with few information barriers that I’m sure helped a lot of students who were not very familiar with electron crystallography.

Some of the most inspiring mentality that I learned was to always have faith in yourself (research-wise) and not be discouraged by other people’s words. On the other hand, one should have an open heart to the work of others and try your best to appreciate their work rather than doubting it.

This grant was of great help in covering my travel expenses. I am sincerely thankful to the selection committee.

Yi Zhou, ShanghaiTech University, China

This was my first time in attending such an overseas international conference. I had a fantastic experience at ECS2023, because of not only the thrilling lectures on both fundamental and cutting-edge science and technology about convergent-beam electron diffraction (CBED), four-dimensional scanning electron microscopy (4D-STEM) and three-dimensional electron diffraction (3D-ED) but also the chance to discuss face to face with pioneers and talented young scientists from all around the world in these fields.

During the school, I was very impressed by the quantitative analysis of CBED data by Professor Jian-Min Zuo from the University of Illinois at Urbana-Champaign (UIUC) and Professor Philip Nakashima from Monash Centre for Electron Microscopy (MCEM). The unit cell, symmetry, sample thickness, atom positions and even orbitals can be analyzed. There were also a lot of lectures that showed us many useful software packages for processing 4D-STEM data with the speakers giving detailed instructions on how to use the software. Although I don’t work on this field, it still inspired me a lot. Lectures on 3D-ED and kinematical and dynamical structure refinement taught me a lot, which will benefit my experiments very much.

I was very honored to give a poster presentation on the evening of the first day of this electron crystallography school to present my up-to-date work about locating the guest species on metal–organic frameworks by 3D-ED. Several other talented young peers also presented their beautiful work, covering different materials and various techniques. It’s really good to know what others are doing and communicate with them.

Finally, I would like to say thanks to the organizers, Professor Laure Bourgeois and Hongyi Xu, for providing me with such a good platform to learn from others and promote myself. At the end of this school, I was awarded an “IUCr Young and Early Career Scientist Award”. This IUCr grant not only provided me with financial support but also gave me a lot of motivation. This is a kind of recognition for my previous research and encouragement for my future career.
