Bridging both life sciences and materials sciences, the conference brings together researchers who utilize laboratory-based instruments, X-ray light sources, electron diffraction, and neutron scattering to explore the structure and dynamics of matter. It serves as a vibrant forum for sharing recent scientific breakthroughs, fostering interdisciplinary collaborations, and highlighting innovations across experimental and computational frontiers

This year’s program features a diverse and timely selection of breakout sessions, reflecting key areas of growth in the field. Topics include energy storage, emphasizing structural insights that enable next-generation energy technologies; AI and its applications in the development of emergent materials; novel materials with transformative properties; and the effects of extreme environments on structures, reveling details on dynamic processes and molecular motion that lead to biomolecular functions and a better understanding of complex soft materials.

Fundamentals of Crystallography: Theory and Practice

 The Caribbean Regional X-ray Science Toward Advancement Laboratory (crXstal) was established in October 2024 in the Department of Chemistry, Faculty of Science and Technology at The University of the West Indies, Mona, Jamaica, as a regional hub dedicated to capacity building in X-ray crystallography through education and research. Its primary objectives are: 1) to teach X-ray crystallography through short courses, training schools and outreach activities aimed at popularizing the technique especially among youth; 2) to facilitate cutting-edge research that address regional challenges and position the Caribbean as a global leader in innovation and 3) crXstal is presently equipped with a Bruker D8 Quest Eco single-crystal diffractometer and an Oxford Diffraction cryostat.

Â

Topics to be covered: Symmetry in crystals. Lattices, unit cells, point groups and space groups. Diffraction of X-rays by crystals. Bragg’s Law. The reciprocal lattice and the Ewald Sphere. Systematic absences, structure factors and electron densities. Use of the International Tables for Crystallography Vol. A. Crystal growth techniques. Crystal selection and mounting. Data collection and reduction. Structure solution and refinement. Structural analysis and reporting â€" molecular graphics and the CIF file. Use of various software packages for structure solution, refinement and display. Structure validation and publication. The Cambridge Structural Database. Introduction to crystallography using synchrotron radiation. Examples of applications of single crystal X-ray diffraction. The programme will include hands-on sessions on the Bruker D8 ECO Quest so students will have the opportunity to collect their own data and solve the structures.

Target Audience: Postgraduate students and researchers/ faculty members from any university, and Industry persons in a STEM discipline.Â

The Polish Crystallographic Meeting, Scientific Workshop and Session of the Young Crystallographers Sections of PCrA will be held at the Institute of Low Temperature and Structure Research of the Polish Academy of Sciences, ul. Okólna 2 in Wrocław.

The Workshop is devoted to selected issues and problems of modern crystallography.

The Scientific Session of the Young Crystallographers Section of PCrAÂ is a forum for exchanging experiences addressed primarily to students, PhD students and young doctors (maximum 5 years after defense).

The topics of the Meeting include basic and applied research on the ideal and real structure of crystals carried out with the use of X-ray radiation obtained both with traditional methods and in synchrotrons, research with the use of neutrons and electrons, problems of symmetry, phase transformations and crystal growth, new research and computational methods and all other aspects of crystallography. The conference is an annual meeting place and a forum for exchanging ideas of all Polish crystallographers.

During the inauguration of the 66th Polish Crystallography Meeting, the winners of the 6th National Crystallography Olympiad will be decorated: http://olimpiadakrystalograficzna.pl.

 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.

Please note: This meeting is happening virtually the week of 3 November. For more information, please contact the organisers.Â
