 At the XXV Congress and General Assembly of the International Union of Crystallography in Prague, it was decided that the 35th edition of the European Crystallographic Meeting would be held in Lviv, Ukraine, in 2025.

 Unfortunately, there is a war in Ukraine, and it is not reasonable to organize a great scientific event in Lviv in 2025. An alternative was thus elaborated where, thanks to a collaboration between the Ukrainian Crystallographic Committee and the Polish Crystallographic Association, the conference site will be Poznan, a city in neighbouring Poland.

The flagship of the European Crystallographic Association (ECA) activities is the European Crystallographic Meeting (ECM), held every year, except when there is an IUCr Congress. The ECMs are the main meeting point for crystallographers in the ECA area to show their recent research. Microsymposia at ECMs are proposed and organized by ECA SIGs.

ECM 34 will be organized at the Padova Congress Centre on behalf of ECA and AIC. It will include all topics of interest to crystallography and it will be organized in synergy with EPIDC 18, which will follow ECM 34 in the same location.

The Young Crystallographers are a working group within the German Society for Crystallography (DGK). For 10 years, we meet regularly in autumn at different universities or the STOE facilities.

These meetings specifically aim to provide a platform for networking and scientific exchange for young scientists with an interest in crystallography, as well as to establish contacts with industry and research institutions.
We want to give young scientists the opportunity to gain early experience in scientific presentation in a relaxed atmosphere and without the stress of a larger conference.

For our grand anniversary, we are happy to meet at the DESY facilities! We are working hard to allow you deep insights as well as a great overview of the possibilities at this large-scale facility.

During the 3-day meeting, you willÂ

• present your own work as a poster (A0 portrait) and lightning talk (~5 min.)
• have the DESY campus tour
• participate in an experiment and get a hands-on experience at a beamline of your choice at PETRA III (see The Experiments)
• hear academic talks from senior scientists
• hear industry talks from our sponsors/partners

At the end of the meeting, you will also have the chance to join a tour of the European XFEL Campus. If you intend to participate, please indicate so during registration. Note that you will need to get to the XFEL facilities by public transport as it is a bit outside the main DESY campus.

The registration fee of 60 € includes the tours and experiments at DESY, coffee breaks as well as lunch and BBQ on Thursday.

Deadline for registration is 22.08.23.

For the past three decades high pressure research has made breakthrough progress in many fields of science mainly due to the significant improvements in the high-pressure apparatus and developments of advanced static and dynamic probes. Most of the experiments at extreme conditions are very challenging and require dedicated techniques to collect crystallographic data with unprecedented speed and resolution to quantitatively characterize pressure/temperature induced transformations in the crystalline lattice. The tunability, brilliance, and collimation of synchrotron X-ray sources provides scientists with unique capabilities for probing the structural, chemical, and physical properties of various types of materials in-situ at extreme pressure, temperature, and strain with ultra-high spatial, temporal and energy resolution. However, in many cases the complex energy landscapes of multicomponent chemical systems require the use of the predictive power of computational methods that play an essential role in extreme-conditions crystallography coupled with physical experiments.

The purpose of the 2022 workshop of the International Union of Crystallography (IUCr) Commission on High Pressure is to bring together researchers who apply extreme-conditions crystallography in combination with other experimental and computational methods to study a wide range of material properties covering various fields of science, including condensed-matter physics, solid-state chemistry, geophysics, materials science, biology, nanotechnology etc. The workshop aims to facilitate extensive discussion and interdisciplinary collaboration.

Students, postdocs and early carrier scientists in particular will find this workshop helpful in gaining improved familiarity with available state-of-the-art methods and how they can be applied to their research.

We plan to organize a tour to the relevant APS beamlines for workshop attendees (pandemic permits) and a half-day tutorial with hands on examples.

Subjecting matter to extreme conditions reveals a multitude of fascinating phenomena, and is applicable to a wide range of disciplines. From the extremophiles that exist in the deepest depths of our oceans to the exotic new materials that are made when atoms are pushed ever closer together, understanding the structure of materials at extreme conditions affects Biology, Chemistry, Physics, Geoscience and Material Science. In order to achieve its goals, high pressure research has been always at the vanguard of technical progress. It is a discipline in which equipment plays a particularly important role. State-of-the-art diamond anvil cells can now achieve megabar ranges of pressure, millions of times atmospheric pressure, with this beaten by an order of magnitude in dynamic compression experiments. In this manner, scientists are able to mimic the conditions in the interiors of giant planets. Nature is even more ambitious, as in the stars petapascal pressures (the order of tens to hundreds billion atmospheres) are reached. In the laboratory, we can even create conditions of pressure, temperature and magnetic fields that are not found naturally, allowing us to complement nature to explore more exotic phases of matter.

Therefore, the course will cover broad ground in the application of extreme conditions crystallography. The topics will span from fundamentals of high-pressure single crystal and powder diffraction, to presenting the many flavors of static and dynamic compression, to reviews of sources for extreme conditions work (synchrotrons, neutrons and free electron lasers). Complementary experimental (Mössbauer spectroscopy, X-ray magnetic circular dichroism, X-ray absorption spectroscopy, inelastic scattering) and computational methods will also be discussed. Diffraction analysis on the structure of liquids, glasses and nanocrystalline materials as well as multigrain crystallography will also be introduced. The lectures will be harmonized with the related sessions of interactive tutorials, providing hands-on experience to the attendees. These workshops will be focused on basic laboratory skills and the elements of data processing software related to the high pressure.

Topics

The main topics will be:

• Production and properties of Synchrotron Radiation;
• Basics of the interaction between matter and radiation;
• X-ray Absorption Spectroscopy (EXAFS and XANES);
• X-ray Diffraction (single crystal and powder diffraction, anomalous scattering);
• Small angle X-ray scattering;
• Photoemission (from valence and from core levels; angular, time and spin resolved);
• IR spectroscopy and microscopy;
• Imaging;
• Data analysis on X-ray Absorption, Powder Diffraction and Core Level Photoemission Spectroscopy experiments
• Applications in many fields (materials, nanoscience, catalysis, earth science, environmental science, cultural heritage, biology and medicine).
