Faculty and students of the Department of Solid State Chemistry Faculty of Natural Sciences (FNS) of NSU participated in the International University of California, Santa Cruz, High Pressure Workshop on High-Pressure Crystallography (IUCr High Pressure Workshop). The workshop was held in Shanghai, China, from September 21 to 26.
The seminar program included presentations on various areas of high-pressure crystallography: from geological research and the analysis of superconducting materials to technical aspects such as the design of synchrotron and neutron stations. The event brought together high-pressure crystallography specialists from around the world, with 169 participants. A competition was held among the young scientists' submissions.
Elena Boldyreva, Professor of the Department of Solid State Chemistry at the NSU Department of Natural Sciences, presented an invited talk online. Poster presentations were presented by Nikita Bogdanov, Senior Lecturer in the Department; Svetlana Sharaya and Polina Kalinina, PhD students; and Grigory Zhdankin, Master's student at the Moscow Institute of Physical Chemistry and Physics. Nikita Bogdanov and Polina Kalinina's work was awarded prizes for the best work in the Young Scientists Competition and for the best talk. The talks presented research results, including those from Russian Science Foundation projects being implemented at NSU: "The Relationship Between Crystal Structure and Photoisomerization of Cobalt Pentaammine with Various Anions" (No. 24-22-00293) and "Structural Aspects of Ferroelectric and Piezoelectric Phase Transitions in Organic Crystals under High Pressure and Low Temperature Conditions" (No. 24-23-00410).
The conference included a tour of the Shanghai Synchrotron Radiation Facility, where participants were able to see the experimental stations designed for studying substances under high pressure. They also visited the HPSTAR Center for Advanced High-Pressure Science and Technology.
The participant shared their impressions:
Grigory Zhdankin, a second-year student of the master's program "Methodological Support for Physicochemical Studies of Condensed Phases" at the Department of Chemical Technology, Faculty of Natural Sciences, NSU:
I really enjoyed the diversity of the oral and poster presentations at the conference: from projects for synchrotron radiation stations designed to study substances under extreme conditions to research in mineralogy and the synthesis of new substances at high pressures (over two million atmospheres). I had the opportunity to interact in person with a large number of interesting people whom I had previously only known through their articles. This gave me a huge boost of motivation to continue my scientific work.
Shanghai itself turned out to be quite an interesting city for tourism. Between listening to presentations, we managed to visit several interesting places: Yuyuan Garden, the Shanghai Aquarium, Nanjing Road, and People's Square.
Polina Kalinina, first-year PhD student at the Faculty of Natural Sciences:
It was fascinating to interact with various scientists, both leading experts in high-pressure crystallography and emerging young researchers. It was also helpful to see firsthand how high pressures are applied in various fields of research—it broadens your horizons and inspires new research beyond your own. For example, I was particularly interested in the work investigating the composition of the Earth's mantle, as well as the work aimed at producing hexagonal diamond—lonsdaleite. It was gratifying to see the conference participants' interest in my work and that of my colleagues; there were many positive wishes and encouragement. I am very motivated when my work is interesting to people who are seeing it for the first time.
Svetlana Sharaya, 3rd year PhD student at the Faculty of Natural Sciences:
A huge number of presentations at the conference were devoted to synchrotron topics and the use of synchrotron radiation for high-pressure crystallography research. It was very interesting to hear the experiences of colleagues from China and other countries in setting up stations and conducting experiments using synchrotron radiation. This was useful for us, as the knowledge gained can be applied at the SKIF facility currently under construction in Koltsovo.
Furthermore, the conference featured presentations that weren't directly related to crystal study methods, but focused on the fundamentals of mathematical crystallography. This was useful for me as a budding scientist. I particularly remember the presentation on predicting crystal symmetry before and after a phase transition, taking into account the structure and properties based on group theory.
