American Crystallographic Association

The American Crystallographic Association (ACA) is a professional organization that focuses on the study of crystals and their structures. It serves scientists and researchers who work in fields like chemistry, biology, and materials science, where understanding crystal structures is essential. The ACA promotes education, collaboration, and the sharing of research through conferences, publications, and resources. By advancing crystallography— the study of how atoms are arranged in crystalline materials— the ACA aids in important discoveries and innovations in various scientific disciplines, helping to improve technologies and deepen our understanding of natural phenomena.
