Share Your Work in Structural Dynamics

As a crystallographer, your research belongs at the heart of our community. Structural Dynamics—the official journal of the American Crystallographic Association and AIP Publishing—highlights cutting-edge discoveries in structure, dynamics, and emerging experimental methods. From time-resolved crystallography and XFEL studies to novel approaches in data analysis and materials science, SDY provides a platform where crystallographers and structural scientists can showcase innovation and impact. Publishing in SDY connects your work directly with an engaged global audience of crystallographers and allied scientists, ensuring visibility among peers who understand and value your contributions.

Right now, we’re especially inviting you to contribute to the special topic “Tribute to a Lifelong Innovator: John Markley and the Evolution of Biomolecular NMR,” with a submission deadline of December 31, 2025. Join your colleagues in advancing the frontiers of structural science—submit your next manuscript to Structural Dynamics.

Introducing the American Association to Advance Powder Diffraction (AAAPD)

We are pleased to share the launch of the American Association to Advance Powder Diffraction (AAAPD)—a new grassroots organization established to serve as a unified voice for the powder diffraction community. The AAAPD brings together scientists and engineers from academia, government, and industry to foster collaboration, advocate for resources, and support the continued advancement of the field.
