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.

In silico digital design methods are becoming more popular in the formulated products industries as tools to anticipate manufacturing and processing bottlenecks before they occur. Particle Informatics tools enable you to leverage the wealth of data in the Cambridge Structural Database (CSD) to provide insight into the surface chemistry and topology of crystal facets.

What we will cover

In this virtual workshop, we will provide an overview of the functionality available in the CSD-Particle suite, focusing on tools for particle surface analysis. The session will include presentations and demonstrations by CCDC expert tutors and a hands-on part for you to try the software, with the tutors available to help you and answer your questions.

You will learn:

- How to use the desktop molecular visualizer software Mercury for Particle Informatics studies.

- How to use the Surface Analysis tool.

- How to calculate Full Interaction Maps on surfaces.

- Recent advances and improvements of the CSD-Particle tools.

- How you can best use Mercury and CSD-Particle in your workflows.

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.

HERCULES is a European course for PhD students and young researchers using Neutrons and Synchrotron Radiation for applications in Biology, Chemistry, Physics, Hard & Soft Condensed Matter.

 The 5-week school includes lectures (60%), hands-on practicals, labs & tutorials (30%), visits, a poster session, group work sessions, ...
Participants will spend one week in a partner institution in Europe among:

• ALBAÂ in Barcelona, Spain
• PETRA III and EU-XFELÂ in Hambourg, Germany
• KIT light source in Karlsruhe, Germany
• SOLEILÂ in Saint-Aubin, France

 This comes in addition to practicals, labs, and tutorials which will take place in Grenoble at ILL, ESRF and Grenoble Laboratories (CNRS, IBS).
