35 European Crystallographic Meeting
|
In PoznaÃ...„
 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.

International School on Quantum Crystallography 2025 â€" Erice, Italy

In Erice, Italy
During this school, we will provide an accessible and in-depth education in quantum mechanics and related semi-empirical methods, tailored to provide a solid foundation in understanding materials structure, physicochemical properties, and the response of materials to physical changes and experimental probes. The theoretical foundations of crystallographic experiments will be briefly recalled, and the methodology of data collection and analysis for quantum crystallography methods will be presented and trained in detail. Speakers at this school will go beyond just theoretical calculations, to demonstrate the deep interplay between theory and experiment: for example, by showing how experimental observations could be used to restrain or constrain first-principles calculations or otherwise showing how calculations could improve the interpretation of an experimental result.
In keeping with this overall aim, the synergy between theoretical and experimental areas will be highlighted to provide a holistic view of the different fields in Quantum Crystallography. This area of knowledge is going through an important boost in the last years, thanks to new coupled approaches and new communities getting in touch with each other. This school will bring together students from these two communities, feeding this new area of knowledge and letting interdisciplinary grow among the students.
Workshops will provide hands-on tutorials on the use and development of software related to the topics, including the development of required input data, and using case studies.
Additionally, the school will benefit from the synergy with the Electron Crystallography School running in parallel, with several lectures shared between the two schools. This will offer a unique opportunity to explore interdisciplinary applications of crystallography in quantum science and structural research.

Synclight 2024 - São Paulo School of Advanced Science on 4th Generation Synchrotron Techniques
|
In Campinas
Promoted by CNPEM and funded by São Paulo Research Foundation (FAPESP), SyncLight 2024 aims to gather young researchers from Brazil and around the world to discuss the recent opportunities offered by advanced experimental synchrotron techniques available at Sirius, the Brazilian 4th generation light source.
Over the past decades, synchrotron light sources have played a significant role in the development of modern natural sciences and engineering. With a wide range of experimental techniques available, synchrotron light sources have revolutionized the way scientists study and characterize materials in the fields of Physics, Chemistry, Biology, Health, Energy, New Materials, Environmental Sciences, and many others.
The interdisciplinary nature of the event, combined with the collaboration of the LNLS User Committee, which includes researchers from various institutions across Brazil, will contribute to the exchange of experiences among young researchers, professors, and experienced researchers. The event's program includes lectures, poster sessions, and guided tours at the facilities will also be organized. Tutorials on experiments conducted, demonstrations on the control of the accelerators, as well as data analysis and simulations taught by LNLS researchers, at the laboratory's beamlines, are also planned.
The theme is particularly relevant to the Brazilian scientific scenario, as Sirius is one of the most modern and brilliant synchrotron light sources in the world. Currently, ten beamlines are open to the scientific and technological community, out of a set of 14 initially planned to cover a wide range of scientific programs. One of the objectives of SyncLight 2024 is precisely to assist in the training and formation of a new generation of user-researchers, capable of benefiting from this large scientific infrastructure in operation in Brazil.
SyncLight 2024 is part of the São Paulo School of Advanced Science (SPSAS) modality, funded by FAPESP, which provides resources to promote short courses in different areas of knowledge in the State of São Paulo.
