The 71st ACA Annual Meeting: Abstract Archive Now Available!  

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.
