During 2 days and a half, we will introduces the participants with the basics of the X rays and neutron diffraction including data treatment and structure determination. The focus will be put on the charge density refinements using different established program (MoPro, XD) for which tutorials will be proposed

Inspired Design, Assembly and Properties of Molecular Materials

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.

The 7th European Conference on Crystal Growth (ECCG7) is an international scientific event that goes beyond European borders. The organizers believe that ECCG7 will have a major impact on the condensed matter physics, chemistry and biological crystallization communities and for materials science researchers, young scientists and PhD students, all being involved in the field of phase formation and crystal growth. ECCG7 follows the 3rd European School on Crystal Growth (ESCG3).

The conference programme will include 15 sessions covering the most advanced research in all topics of crystal growth phenomena, theory, experiments and applications, planned to be presented and discussed in three plenary lectures, about 30 invited talks, various oral presentations and poster sessions. For the first time, ECCG7 will implement three parallel sessions.

Abstract submission deadline: 15 April 2022

Young researchers and PhD students from all over Europe and the rest of the world are invited to participate in the 3rd European School on Crystal Growth (ESCG3), which will be held prior to the Seventh European Conference on Crystal Growth (ECCG7).

ESCG3 will implement theoretical lectures, pedagogical experimental reviews and, for the first time, demonstrations on both computers and pulling machines â€" either during the lectures or during specific time slots â€" in the main branches of crystal growth: bulk crystal growth, thin-film growth and epitaxy, and biological crystallization. It will comprise 18 academic hours and 6 demonstrations hours delivered by some 12 lecturers over 4 days, all of them renowned experts in the domain they will cover.

Capacity: 60 students.

The School is intended primarily for young researchers in the chemical, molecular and solid state sciences. Applicants from all regions of the world will be considered. The goal is that the participants gain hands-on experience plus a theoretical background in the art and science of routine crystal and molecular structure determination of small molecules by single-crystal X-ray crystallography, as well as in the interpretation and presentation of results. The School will consist of lectures, computer exercises and practical work. The School is ideal for anyone for whom a knowledge of crystal structure analysis would be particularly helpful in their current research. The School is not suitable for persons interested specifically in powder diffraction techniques or macromolecular crystallography.

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.

AICS2021 school is about fundamentals of crystallography and it is thought for students and researchers wishing to exploit crystallographic techniques in their research for the first time or those who already use crystallography and want to deepen basic theoretical aspects. Several topics will be discussed: from symmetry to reciprocal/real space, from diffraction theory to the math behind the structural solution. Interactive classes will be held after each theoretical session, thus giving the opportunity to practice what has been learned.

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;
