The 2023 Crystallographic Computing School is intended for all programmers and method developers in crystallography. All areas of crystallography are included (macromolecular, chemical, materials, etc.). Invited are all ages and all levels of experience. A basic knowledge of crystallography and programming is expected. We have no preference for selected programming languages. The school is a satellite to the 26th IUCr Congress in Melbourne.

The 18th International Summer School on Crystal Growth will be organised in Parma, the Italian Capital of Culture 2020â€"2021, as an in-person event, after the change of date imposed by the pandemic emergency. The Campus of Science and Technology of Parma University has been chosen to host this event. A friendly and stimulating environment will facilitate discussions and new contacts between lecturers and participants.

As per tradition, the School is organized in conjunction with the International Conference on Crystal Growth and Epitaxy, which takes place in Naples in the following week.

The ADD2022 School and Conference aim to deepen the understanding and to further the training of the various communities working on real-space data analysis for neutron and x-ray diffraction techniques.  Fourier transformation of diffraction data into real-space, traditionally used for the structural determination of liquids and glasses, is now increasingly employed for partially-disordered crystalline powder samples, as well as for single-crystal samples exhibiting some local atomic disorder, and most recently for short-range spin-spin correlations in disordered or frustrated magnetic systems (in the case of neutron diffraction).

The scientific scope of ADD2022 pertains to both x-ray and neutron diffraction techniques, and will again include single-crystal diffuse scattering as an integral part of the School and the Conference. Note that we also welcome presentations and participants in the field of e-beam diffraction having real-space analysis techniques.  The School proposes pedagogic lectures on real-space data-analysis techniques followed by 9 separate sessions of hands-on tutorials for training with various data-modelling software packages: DiffPy-CMI, diffpy.mpdf, DISCUS, Dissolve, EPSR, PDFgui, RMCProfile, Spinvert and Yell.  The Conference proposes 8 invited talks and about 16 additional oral contributions, as well as a poster session.

The Fourier transformation of diffraction data into real-space produces a Pair-Distribution Function (PDF) that provides a model-independent "snapshot" of the local structure within the sample.  The PDF(r) thus probes both static and dynamic atomic correlations (and also magnetic spin-spin correlations in the case of neutron diffraction).  The so-called "PDF-analysis" technique is therefore complementary to the well-known Rietveld method of refining diffraction data in Q-space that provides a space-time averaged picture of the sample's structure.  PDF-analysis now enjoys a wide field of application, in particular to nano-structured materials.

Building on the success of our previous ADD workshops in Grenoble (ADD2019 of 17-22 March 2019, ADD2016 of 7-11 March 2016, ADD2013 of 18-22 March 2013, ADD2011 of 12-14 October 2011), the ADD2019 School+Conference will start Sunday evening 16 October 2022 and finish Friday afternoon 21 October, a full 5-day programme that includes 2-1/2 days for the School followed by 2-1/2 days for the Conference, basically the same format as for ADD2019.

As compared to ADD2019, the 2022 edition includes two additional hands-on tutorials: (1) Dissolve, which builds on the success of EPSRÂ and employs similar techniques, but utilises a full classical forcefield and is extensible to multi-configuration, million-atom simulations, and (2) diffpy.mpdf, which as an extension module of DiffPy-CMI allows for real-space modeling of local magnetic spin correlations.

And as for ADD2019, ADD2022 also features pedagogic lectures on nitty-gritty data-reduction and data-correction techniques for x-ray and neutron diffraction as concerns liquids/glasses, disordered crystals and single-crystal diffuse scattering.

Real-space analysis of diffraction data deals with general structural concepts such as atomic/spin distribution functions and structural/magnetic correlation lengths, and now employs standard formulae common to neutron, x-ray and other diffraction techniques.  It therefore facilitates a synergetic convergence of hitherto largely disjoint communities: liquids/glasses diffraction, crystalline powder diffraction, single-crystal diffuse scattering and diffuse magnetic scattering.

• Symmetry analysis using representation theory and the SARAh program and ISOTROPY Suite
• Magnetic space groups using the Bilbao Crystallographic Server
• Refinement strategies using the FullProf Suite, GSAS-II and Jana
• Magnetic structure determination from powder and single-crystal dataÂ
• The school is intended for graduate students, postdocs, and research scientists who have a working knowledge of crystallographic refinement and will benefit from incorporating the techniques of magnetic structure determination from neutron diffraction into their research.

The IUCr Commission on Electron Crystallography, the ECA Electron Crystallography SIG04 and the French Microscopy Society (SFµ) are organising an “Electron Crystallography School” (ECS) as a satellite event to the 33rd European Crystallographic Meeting (ECM33). The school will take place right after the ECM33, on the 29th August â€" 1st September 2022 in Paris area.

The Polish Synchrotron Radiation Society (PSRS) has been organizing this International School and Symposium on Synchrotron Radiation (ISSRNS) since 1991. The aim of this interdisciplinary meeting is to bring together scientists and students working with synchrotron radiation. The meeting will focus on novel applications of synchrotron radiation in physics, chemistry, materials and life sciences.

The programme of the Symposium will comprise invited lectures (40 min), oral presentations (20 min), short contributions (10 min) and poster presentations. The short contributions are for students to present their research results. The official language of the meeting is English.

Course Topics:Â Â

• Fundamentals of DiffractionÂ

• Protein Crystallization Techniques

• Crystallization of Small Molecules

• Data collection, reduction, and analysisÂ

• Structure solution & refinement

• Data validation, CIF preparation and data handling

• Crystallographic Databases (CSD & PDB)

• Powder Diffraction - Rietveld refinement

• Powder Diffraction - Structure Solution

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.

As part of the scientific activities of the 18^th edition of the International Small-Angle Scattering Conference (SAS), the LNLS/CNPEM is organizing the 7^th School of Small Angle X-ray Scattering (SAXS School). The satellite school will take place at Sirius on 16 to 20 September 2022, which are the following days of the 18^th SAS 2022 Conference.

In this edition, the school will be focused on the scattering data analysis of biological systems, like proteins and membranes. Moreover, there will be both international and national well-known researchers giving classes.

Â

To the present date, the organizing committee are planning a 100% on-site school since it will be included “hands-on” experiments at Cateretê beamline.

The school is proposed for students and early career scientists enthusiastic to learn SAXS.
