• Synchrotron radiation
• Small-molecule crystallography

The Latin American Powder Diffraction Conference (LAPDiC) will be an event in Latin America entirely dedicated to all aspects of the analysis of polycrystalline materials using diffraction methods (X-rays, neutrons, and electrons). Inspired by the successful European Powder Diffraction Conference (EPDIC ), LAPDiC aims to become an itinerary conference for researchers in the field across Latin America and beyond, serving as an ideal platform for presenting and disseminating new developments in powder diffraction instrumentation, analysis techniques, and scientific applications.

LAPDiC will bring together experts from universities, research institutes, and industry partners to share their knowledge, discuss current trends, and tackle challenges in powder diffraction. The event will provide a unique opportunity for professionals in the region to network, foster collaborations, and build a more robust scientific community.

The LAPDiC organizing committee, in collaboration with the Latin American Crystallographic Association (LACA) and the Brazilian Crystallographic Association (ABCr), is thrilled to invite you to Fortaleza, CE, Brazil, for the inaugural edition of the Latin American Powder Diffraction Conference.

2025 Pittsburgh Diffraction Conference (PDC)

Hosted by Brookhaven National Laboratory
October 9–12, 2025

On behalf of the Conference Committee, we are delighted to invite you to 82nd annual Pittsburgh Diffraction Conference (PDC). This year’s conference will be held October 9–12, 2025 at Brookhaven National Laboratory, on New York’s beautiful Long Island.
 

The Pittsburgh Diffraction Conference is one of the longest-running scientific meetings in North America focused on the advancement of structural science through diffraction-based methods. 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.

This intensive three-day workshop offers a thorough introduction to modern powder diffraction techniques, combining theoretical foundations with practical applications. The program is designed for graduate students, researchers, and professionals aiming to deepen their understanding and hands-on skills in phase identification, quantitative analysis, and structure determination using powder X-ray diffraction data.

The course begins with the fundamental principles of powder diffraction and qualitative phase analysis, including the use of databases and software (PDF-5+, JADEPro and Qualx2.0). Day 2 focuses on quantitative phase analysis, structure solution, and Rietveld refinement, supported by guided exercises using EXPO and TOPAS software. The final day explores advanced topics such as total scattering, Pair Distribution Function (PDF) analysis, and microstructural characterization through size-strain analysis.

Throughout the course, participants will engage in practical sessions aimed at developing autonomy in data interpretation, profile fitting, and structure modelling using widely adopted software packages in the field.

The Polish Academy of Sciences Crystallography Committee sets itself the goal of increasing students' motivation to acquire knowledge in the field of crystallography, which is an important element of education of graduates of natural sciences and engineering. Since 2014, the National Crystallography Olympiad has been organized cyclically under the patronage of the Committee. In 2025, the 6th edition of this competition will be held.

The official announcement of the results and award ceremony will take place on June 26, 2025, as part of the 66th Polish Crystallographic Meeting in Wrocław.

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.
