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

Periodic order is the sine qua non of crystallography. Yet sometimes it is the departure from order that is crucial for material function. Proteins, frustrated magnets, photovoltaics, battery materials, high-temperature superconductors — there are many examples of important systems where disorder of one sort or another plays a pivotal role. Crystallographically, the signature of disorder is the existence of a diffuse component to the scattering function, usually orders of magnitude weaker than the conventional Bragg scattering. The advent of intense radiation sources, the development of revolutionary detector technologies, and the ready availability of high-performance computing have collectively transformed our ability to measure and interpret diffuse scattering from disordered crystals. As a result, scientists across many disciplines — from biochemistry to condensed-matter physics — are discovering all sorts of new types of disorder and importantly, all sorts of new ways in which disorder is critical for function.
This course will cover the background necessary to measure and interpret diffuse scattering from disordered crystals. Its contents span the theory of diffraction and diffuse scattering, the practicalities of its measurement, and the many different approaches taken to its interpretation. The programme is loosely split into two strands – one with a focus on materials chemistry & physics and the other concerned mostly with protein dynamics. Collectively, the course will cover the various origins of diffuse scattering (e.g. dynamics, compositional/displacive disorder, magnetic disorder), and its form in both single-crystal and powder samples. There will be extensive discussion of real-space interpretations, including the well-known pair distribution function (PDF) and its variants (e.g. 3D-ΔPDF). These lectures will draw on and highlight key scientific discoveries from the recent literature. In parallel to the lecture course, the course will offer a broad selection of tutorials and workshops that will cover many of the key analysis approaches: such as molecular dynamics, Monte Carlo simulations, the Debye equation, small-box and big-box atomistic modelling.
Kartik Ayyer is an independent Max Planck Research Group leader at the Max Planck Institute for the Structure and Dynamics of Matter since 2018. After receiving his BTech in Engineering Physics from the Indian Institute of Technology ((IIT) Delhi in 2009, Kartik pursued a PhD at Cornell University on reconstruction algorithms for X-ray single particle imaging under the supervision of Veit Elser. Following this, he moved to Hamburg to work with Henry Chapman in 2014 to get closer to the experimental side of X-ray diffraction and imaging at X-ray free-electron lasers. Among other topics, he acquired an interest in diffuse scattering of protein crystals, where he developed methods to obtain higher resolution electron densities than from just the Bragg peaks. He is also developing algorithms to use the additional information to understand conformational dynamics of the molecules within the crystal. He is especially interested in membrane protein systems which are relatively poorly ordered.

Helen Ginn is a post-doctoral research associate at Diamond Light Source, UK who specialises in methods development for structural biology. She obtained her DPhil at Oxford University in improved methods for data reduction for serial crystallography at synchrotrons and X-ray free electron lasers. After completing her doctorate, she changed focus to development of methods which would benefit structural biology as a whole, by beginning the Vagabond project, a structural refinement program which describes proteins through their bond network rather than using an atomic description. This new model description results in a dramatic reduction in the parametrisation, and benefits both refinement stability and establishing the ground truth in electron density maps. Alongside this, she developed cluster4x, which clusters datasets based on the crystallographic data, atomic coordinates or any arbitrary metadata. She has also expanded cluster4x to contribute to antibody clustering methods and interpretation of neutralisation capacity of recovered SARS-CoV-2 patients and immunised individuals. Her future direction sets to combine the improved refinement power from Vagabond with the knowledge which can be derived by running cluster4x on multiple datasets, in order to refine a single model of a protein against an arbitrary number of datasets from any combination of major structural solution methods.
Dr. Guagliardi is a senior scientist at Institute of Crystallography (IC) of CNR, Italy, Como branch. Her major research interest focuses on the development and application of experimental and modelling tools to investigate nanocrystalline materials at the atomic and nanometer scales based on X-ray total scattering, so that both Bragg and diffuse scattering are equally taken into account. On this topic, she has been coordinating an extended network of collaborations, set at the Total Scattering Laboratory (To.Sca.Lab) in Como, which includes scientists from University of Insubria and CNR, and from the Material Science Beamline of the Swiss Light Source, where total scattering experiments are carried out in the wide-angle region. Here, suitable data acquisition and data reduction protocols have also been developed. A major research line in the field is the modelling in reciprocal-space, based on atomistic models of nanocrystals and composites, and the use of the Debye Scattering Equation, with original contribution to the development of dedicated computational tools (Debussy Suite). Advances of this approach, together with combination of wide and small angle scattering, have been pursued through investigations of ultrasmall semiconductor nanocrystals (metal chalcogenides and metal halide perovskites), particularly from colloidal synthesis, but also metals, oxides and nanocomposites. The goal is extracting quantitative information on size- and surface-induced structural distortions, symmetry breaking, lattice strains and different kinds of defectiveness for structure-property correlation studies.
During her education and career, she acquired a broad background in crystallography, diffraction techniques and ab initio structure determination by Direct Methods, working in the group led by Prof. C. Giacovazzo, and contributed to the development of popular crystallographic packages (SIR92/SIR98 and EXPO) to solve crystal structures by single crystal and powder diffraction data. She got a PhD in Chemistry at the University of Insubria, Italy, with a Thesis on the application of the Debye Scattering Equation on nanomaterials for investigating structure-property correlations. She has a long-standing experience in the organization of schools on fundamental crystallography and total scattering and in managing hands-on with the packages she co-authored.

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

Periodic order is the sine qua non of crystallography. Yet sometimes it is the departure from order that is crucial for material function. Proteins, frustrated magnets, photovoltaics, battery materials, high-temperature superconductors — there are many examples of important systems where disorder of one sort or another plays a pivotal role. Crystallographically, the signature of disorder is the existence of a diffuse component to the scattering function, usually orders of magnitude weaker than the conventional Bragg scattering. The advent of intense radiation sources, the development of revolutionary detector technologies, and the ready availability of high-performance computing have collectively transformed our ability to measure and interpret diffuse scattering from disordered crystals. As a result, scientists across many disciplines — from biochemistry to condensed-matter physics — are discovering all sorts of new types of disorder and importantly, all sorts of new ways in which disorder is critical for function.
This course will cover the background necessary to measure and interpret diffuse scattering from disordered crystals. Its contents span the theory of diffraction and diffuse scattering, the practicalities of its measurement, and the many different approaches taken to its interpretation. The programme is loosely split into two strands – one with a focus on materials chemistry & physics and the other concerned mostly with protein dynamics. Collectively, the course will cover the various origins of diffuse scattering (e.g. dynamics, compositional/displacive disorder, magnetic disorder), and its form in both single-crystal and powder samples. There will be extensive discussion of real-space interpretations, including the well-known pair distribution function (PDF) and its variants (e.g. 3D-ΔPDF). These lectures will draw on and highlight key scientific discoveries from the recent literature. In parallel to the lecture course, the course will offer a broad selection of tutorials and workshops that will cover many of the key analysis approaches: such as molecular dynamics, Monte Carlo simulations, the Debye equation, small-box and big-box atomistic modelling.
Kartik Ayyer is an independent Max Planck Research Group leader at the Max Planck Institute for the Structure and Dynamics of Matter since 2018. After receiving his BTech in Engineering Physics from the Indian Institute of Technology ((IIT) Delhi in 2009, Kartik pursued a PhD at Cornell University on reconstruction algorithms for X-ray single particle imaging under the supervision of Veit Elser. Following this, he moved to Hamburg to work with Henry Chapman in 2014 to get closer to the experimental side of X-ray diffraction and imaging at X-ray free-electron lasers. Among other topics, he acquired an interest in diffuse scattering of protein crystals, where he developed methods to obtain higher resolution electron densities than from just the Bragg peaks. He is also developing algorithms to use the additional information to understand conformational dynamics of the molecules within the crystal. He is especially interested in membrane protein systems which are relatively poorly ordered.

After a Laurea in Theoretical Chemistry at the University of Milan (I) and a Master in Polymer Science and Technology at the Polytechnic of Milan (I), Silvia Capelli obtained a PhD in Chemical Crystallography from the University of Bern (CH). In 2000, she moved to Grenoble (F) to work as beamline post-doc at the European Synchrotron Radiation Facility, first at the single crystal station of the Swiss-Norwegian Beamline (BM1A) and then at the Material Science beamline ID11. In 2008 she joined the Institute Laue-Langevin to work initially as co-responsible of the D10 single crystal neutron diffractometer with three-axis energy analysis and then as co-responsible of the single crystal thermal neutron diffractometer D19.
Currently, Silvia is an instrument scientist at the ISIS Neutron and Muon Facility at the Rutherford Appleton Laboratory (Oxford, UK), which she joined in 2014 as responsible for the single crystal neutron diffractometer SXD.

Helen Ginn is a post-doctoral research associate at Diamond Light Source, UK who specialises in methods development for structural biology. She obtained her DPhil at Oxford University in improved methods for data reduction for serial crystallography at synchrotrons and X-ray free electron lasers. After completing her doctorate, she changed focus to development of methods which would benefit structural biology as a whole, by beginning the Vagabond project, a structural refinement program which describes proteins through their bond network rather than using an atomic description. This new model description results in a dramatic reduction in the parametrisation, and benefits both refinement stability and establishing the ground truth in electron density maps. Alongside this, she developed cluster4x, which clusters datasets based on the crystallographic data, atomic coordinates or any arbitrary metadata. She has also expanded cluster4x to contribute to antibody clustering methods and interpretation of neutralisation capacity of recovered SARS-CoV-2 patients and immunised individuals. Her future direction sets to combine the improved refinement power from Vagabond with the knowledge which can be derived by running cluster4x on multiple datasets, in order to refine a single model of a protein against an arbitrary number of datasets from any combination of major structural solution methods.
Dr. Guagliardi is a senior scientist at Institute of Crystallography (IC) of CNR, Italy, Como branch. Her major research interest focuses on the development and application of experimental and modelling tools to investigate nanocrystalline materials at the atomic and nanometer scales based on X-ray total scattering, so that both Bragg and diffuse scattering are equally taken into account. On this topic, she has been coordinating an extended network of collaborations, set at the Total Scattering Laboratory (To.Sca.Lab) in Como, which includes scientists from University of Insubria and CNR, and from the Material Science Beamline of the Swiss Light Source, where total scattering experiments are carried out in the wide-angle region. Here, suitable data acquisition and data reduction protocols have also been developed. A major research line in the field is the modelling in reciprocal-space, based on atomistic models of nanocrystals and composites, and the use of the Debye Scattering Equation, with original contribution to the development of dedicated computational tools (Debussy Suite). Advances of this approach, together with combination of wide and small angle scattering, have been pursued through investigations of ultrasmall semiconductor nanocrystals (metal chalcogenides and metal halide perovskites), particularly from colloidal synthesis, but also metals, oxides and nanocomposites. The goal is extracting quantitative information on size- and surface-induced structural distortions, symmetry breaking, lattice strains and different kinds of defectiveness for structure-property correlation studies.
During her education and career, she acquired a broad background in crystallography, diffraction techniques and ab initio structure determination by Direct Methods, working in the group led by Prof. C. Giacovazzo, and contributed to the development of popular crystallographic packages (SIR92/SIR98 and EXPO) to solve crystal structures by single crystal and powder diffraction data. She got a PhD in Chemistry at the University of Insubria, Italy, with a Thesis on the application of the Debye Scattering Equation on nanomaterials for investigating structure-property correlations. She has a long-standing experience in the organization of schools on fundamental crystallography and total scattering and in managing hands-on with the packages she co-authored.
