RECAP: 72nd ACA Annual Meeting

July 29 - August 3, 2022 | Portland, Oregon

The American Crystallographic Association returned to an in-person gathering for the 72nd annual meeting. Scientists interested in biological, chemical, and material structures will travel to the heart of Portland, Oregon, July 29 - August 3, 2022. In an effort to remain flexible in this dynamic time, the ACA plans to offer a selection of the in-person content as fully accessible, hybrid presentations. The past two years have kept us physically apart; but many researchers who cannot attend in person have enjoyed the flexibility of virtual events. This partial hybrid format will hopefully foster lively, cooperative discussions from a diverse body of attendees. We also look forward to celebrating the diversity of our scientific interests. With the recent addition of “The Structural Science Society” to the ACA’s title, the meeting will host sessions in an expanded range of disciplines. Topics will cover single-crystal, powder, and fiber diffraction with X-rays, neutrons and electrons; scattering; cryogenic electron microscopy; advanced capabilities at national synchrotron and neutron sources; and many more!
