Structural Science Awakens: 71st Annual Meeting of the American Crystallographic Association

July 30, 2021 - August 5, 2021 | #acamtg2021 | #vACAmtg2021 

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.  See the list of sessions and events....


The ACA 2021 Annual Meeting will be 100% virtual with the entire meeting being streamed live with the ability for questions and answer sessions in real time.  Once registered, you may attend any sessions and/or events that you wish.  




Workshops are designed for individuals in the same field, discipline or interests to network and learn the most recent developments and techniques.  This year the ACA is excited to offer FIVE workshops.  




The ACA will be holding FOUR virtual poster sessions. Poster sessions are organized by the Poster Chairs and feature presentations covering a range of crystallography topics.  As a way to “exhibit” in our virtual space, our vendors will have their own dedicated breakout rooms (DBR) in the poster sessions.  
2021 Confirmed Exhibitors: AIP, ThermoFisher Scientific, Rigaku, Art Robbins Instruments & Douglas Instruments



The 2021 ACA Meeting Transactions Symposium, entitled “Function Follows Form: Celebrating the 50th Anniversary of the Protein Data Bank,” will celebrate the 50th anniversary of the Protein Data Bank. Since 1971, 3D macromolecular structure data have been expertly archived, validated, biocurated, and safeguarded by the PDB, the first open-access digital data resource in biology. The 2021 ACA Transactions Symposium is dedicated to celebrating the manifold contributions to fundamental biology, biomedicine, bioenergy, and bioengineering/biotechnology made by PDB Data Depositors and PDB Data Consumers over the past five decades. 


This year, the ACA/YSIG will hold a special Zoom meeting with volunteering ACA mentors and younger ACA mentees. At this session volunteer ACA mentors and mentees can have one-on-one group chats, giving everyone an opportunity to ask questions about careers in the structural sciences. This event is free to ACA2021 attendees but pre-registration for the event is required.
