2025 Pittsburgh Diffraction Conference (PDC)

Hosted by Brookhaven National Laboratory
October 9â€"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 9â€"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.

Welcome to the 2nd Young Crystallographers Meeting, which will take place from December 2nd to 5th, 2025 in Rennes at the Institut des sciences chimiques de Rennes. This scientific event was planned by popular demand as a follow up of the YCM1, which happened in Strasbourg in 2023.
This meeting is intended for young crystallographers (researchers, doctoral students, post-doctoral students, and engineers) from all sciences combined and all European countries.

The multidisciplinary character of crystallography will be promoted during this event with sessions mixing talks from Biology, Chemistry, Physics, Mineralogy and Heritage Science fields.

The objectives of the YCM2 are to gather young crystallographers in a multidisciplinary and international context, to create opportunities for scientific exchange, and to provide networking opportunities with industry with a specific focus on the training and career development of the young scientist participants.

• Theoretical and experimental studies of electronic structure and dynamics
• Spectroscopy techniques (e.g. photoelectron spectroscopy, X-ray absorption/emission spectroscopy, electron energy loss spectroscopy)
• Spectromicroscopy (e.g. PEEM, STM, nanoARPES)
• Applications in various fields ranging from correlation physics and materials science to AMO science, chemistry and biology

Join us for the first edition of FrostByte, a meeting for computational cryo-EM methods developers in the San Francisco Bay Area.

This is an event for the Bay Area cryo-EM methods community to connect, share practical insights, and discuss day-to-day challenges. While we welcome attendees from all backgrounds and roles, the focus will be on technical discussions among those directly engaged with computational methods in their daily work.

We bring together experts at the intersection of microscopy and mass spec, topics include soft landing, holography, cryoEM, AFM, native MS, top-down proteomics and various single molecule imaging and mass spectrometry techniques to characterize (biological) macromolecules.

The first XTOP conference was held in Marseille in 1992. With an initial focus on X-ray topography andhigh-resolution X-ray diffraction, the conference has always combined aspects of X-ray scattering and X-ray imaging. Over time, other related topics such as X-ray phase-contrast imaging, tomography and microscopy, and various scanning X-ray imaging techniques have been added.

Today, XTOP brings together scientists working on X-ray diffraction, reflection, grazing-incidence scattering, standing-waves, coherent diffraction, and ptychography techniques, as well as X-ray microtomography, microscopy and other imaging techniques based on phase, diffraction, scattering, or spectroscopic contrasts.

XTOP is a leading scientific conference on instrumentation, methods, and applications of laboratory and synchrotron-based X-ray diffraction and imaging techniques.
