Scientists interested in molecular and materials structure with specialties in biology, chemistry, geosciences, materials science and more will converge virtually for the 71st Annual Meeting of the ACA. The theme for the 2021 meeting is “Structural Science Awakens,” which celebrates the ACA’s new tagline “The Structural Science Society.” Scientific sessions and workshops will highlight new developments in single-crystal and powder diffraction, scattering, cryo-EM, micro-electron diffraction, and advanced capabilities at national x-ray, neutron, and EM facilities.  Explore the list of ACA2021 sessionsworkshops and awards.

Make an impact on your career and submit an abstract by May 23, 2021 to present at the 2021 ACA Annual Meeting. Meet and network with scientists at all stages of their career—including some of the best-known names in structural science.  The opportunity to present and talk about your research with others can make all the difference in your success.
