New experimental and theoretical approaches in the field of high pressure crystallography allow us to address fundamental scientific questions in disciplines such as Physics, Chemistry, Biology, Geosciences and Materials Science. High pressure - from the very modest pressure required to induce the denaturation of proteins and modify intermolecular interactions, through the higher pressures required to synthesise new materials for technological application, to the ultra-high pressures required to radically alter the chemical physical properties of simple elements and materials or recreate the conditions found in Earth's and other planets' interior - is making it a versatile and central tool in condensed matter science.
Fundamental topics covered in the course include experimental techniques for pressure generation, X-ray and neutron diffraction on single crystal and powder materials, comparative structural studies and combined high-temperature and low-temperature experiments. These will be demonstrated through examples of different chemical and structural complexity, from minerals to ices and biomolecules. Specialized and frontiers high-pressure research topics will include computational crystallography, dynamic compression, characterization of liquids and glasses and pair distribution function analysis. The course will be rounded up by illustrating the use of high-pressure as a means to study and access new materials for industrial application such as pharmaceuticals, energy storage, magnetic and ultra-hard materials.
Lectures will be complemented by demonstration and workshop sessions. The course will provide a platform for young and senior scientists to interact and identify as well as discuss new challenges in this rapidly evolving and vibrant research area.

The focus of my research for the past 30 years has been to determine the structure-property relationships of key industrial and geological materials to provide the basis for rationale materials design and understanding geological processes. The details of the arrangement of the atoms within a solid determine its physical, mechanical, thermodynamic, elastic and chemical properties. So, to determine how the properties of materials depend on their structures, I determine how their properties and structures change under high pressures. In the past, I have developed and established novel methods for single-crystal X-ray diffraction at extreme conditions in order to characterize and understand the fundamental relationship between the atomic-scale structures and properties of materials. The software packages that I have developed for diffractometer control and processing of data are distributed freely from my web site, www.rossangel.net. Workshops and tutorials to show how they can be used to collect and process diffraction data will be given during the Erice school. I have also used diffraction methods in combination with Landau theory, symmetry-mode analysis, and a novel topological forward-modelling technique that I have developed, to determine the structure-property relationships of framework structures. These include the most abundant minerals in the Earth and the most important materials for electronics (perovskites) and chemical engineering (zeolites and MOFs).

Trained as a physical chemist and a solid-state chemist, I started my research carrier 35 years ago at the Institute of Solid State Chemistry and Mechanochemistry (Novosibirsk, Russian Academy of Sciences). My early research focused on the study of photomechanical effects (crystals bending) in crystals of coordination compounds. I was interested in the general role of mechanical stresses and strain in solid-state reactivity. This led me to the fascinating field of high-pressure research, which has been the focus of my scientific career since 1991. I began my work in this field when I first visited Philips-University in Marburg/Lahn (Germany) to carry out an IR-spectroscopy study at high pressures. I am greatly indebted to Dr. Ahsbahs, Dr. Uchtmann, Prof. F. Hensel and the Humboldt Foundation for the wonderful years in Marburg, during which time I learnt a lot about a broad range of high-pressure techniques. Having returned to Russia from Germany, I started a research group in Novosibirsk, Russia, which is now very well established. We combine X-ray single-crystal and powder diffraction at high pressures with IR- and Raman spectroscopies, as well as optical microscopy. We use laboratory instruments (STOE-IPDS-2T, STOE STADI-4 and Agilent Xcalibur Gemini R Ultra), as well as synchrotron radiation sources for our work. From high-pressure research of coordination compounds that exhibit photomechanical effects, I moved to studying the effect of pressure on solid pharmaceutical compounds, amino acids and other biomimetic molecules. Our main interests are in the polymorphism of drugs and biomimetics, the properties of hydrogen bonds and the role of kinetic factors in solid-state transformations. We also continue to study the relation between stresses and solid-state reactivity, with particular interest in photo- and thermo- mechanical effects. I was a lecturer at the first Erice School on High-Pressure Crystallography (directors P. McMillan and A. Katrusiak), a co-director of the second Erice School on High-Pressure Crystallography (together with P. Dera), and I am honored to have been invited as a lecturer to the third edition of this school.

Malcolm Guthrie has been working in the field of high-pressure diffraction at major neutron and synchrotron facilities for almost 17 years. He has studied how the structure of matter responds to extremes pressure across multiple length scales and his interests span crystalline, liquid, amorphous and low-dimensional substances.
Dr Guthrie completed his PhD in 2002 in the UK before going on to work for the fledgling SNS project, at the time based at the IPNS Facility in Chicago, USA. After a second postdoc at the ISIS Facility in the UK, he returned to the US, working first as a staff scientist at the APS synchrotron and then moving to Washington DC to lead the neutron activities of the Geophysical Laboratory (GL). During his time at GL, he worked closely with the SNS Facility and made substantial contributions to operations at the SNAP high-pressure beamline. Most notably, he lead the programme to develop powder neutron diffraction in diamond-anvil cells at pressures approaching 100 GPa. In 2014, he moved to Sweden to work for the European Spallation Source (ESS) where he aims to help realise the enormous potential of this bright new source for high-pressure neutron science.

Short CV: PhD at the Ecole Normale Superieure de Lyon (France), Carnegie Fellow at the Geophysical Laboratory in Washington D.C. (USA), and currently Professor at the University Pierre and Marie Curie, Institute of Earth Sciences in Paris (ISTeP), and visiting professor at the University of Edinburgh (UK), School of Physics. My interest in the properties of liquids at high pressure started during my PhD with the study of molten Fe and Fe-alloys in the perspective to better constrain the chemical composition of the Earth's core. Since then, the advancement in synchrotron x-ray-based techniques have allowed us to study lighter amorphous and molten materials, and simultaneously extend the P-range to the megabar. The range of properties that can be measured in situ using X-rays are the short-range order (local structure), the density, and the viscosity though in a restricted P-range for the latter. In the course of the last 10 years, we have been studying liquid water, amorphous sulphur, and lately magmas at depth. Those are chemically much more complex materials, and other issues must be solved such as the local structure around elements present in minor amounts but potentially key to understanding some physical properties.
