Structural science is strongest when the community comes together

ACA connects researchers, educators, and practitioners across techniques, applications, and career stages—offering meetings, travel support, recognition, leadership, and a network that extends beyond ACA through society and industry partnerships.

Advancing Ultrafast Structural Science

New research in Structural Dynamics demonstrates a shot-to-shot acquisition method that significantly improves ultrafast electron diffraction measurements, enabling clearer views of how structures change in real time. ACA members’ research belongs in Structural Dynamics—and members receive a discount on article submissions, making it even easier to share cutting-edge work with the structural science community.
