"No one can whistle a symphony. It takes a whole orchestra to play it."
— H.E. Luccock
The triennial 2026 IUCr Congress will take place in Calgary, Alberta, Canada and is jointly hosted by three equal partners: the Canadian National Committee for Crystallography (CNCC), the U.S. National Committee for Crystallography (USNC/Cr), and the American Crystallographic Association (ACA).
The Canadian National Committee for Crystallography
The Canadian National Committee for Crystallography (CNCC) is a prominent organization dedicated to advancing the field of crystallography in Canada. Established with a mission to foster collaboration, research, and education in crystallography, the CNCC plays a vital role in connecting scientists, researchers, and academics across the country. The committee actively promotes the use of crystallographic techniques to study the structure and properties of materials, molecules, and biological systems. Through its initiatives, workshops, conferences, and publications, the CNCC creates a vibrant platform for knowledge exchange and supports the growth of crystallography as an essential discipline in the Canadian scientific community. With a commitment to excellence and innovation, the CNCC significantly contributes to the understanding of matter and facilitates groundbreaking discoveries with broad applications in various scientific and technological domains.
US National Committee for Crystallography (USNC/Cr)
The US National Committee for Crystallography (USNC/Cr) is a vital organization that plays a pivotal role in promoting and advancing the field of crystallography in North America. As an integral part of the International Union of Crystallography (IUCr), the USNC/Cr facilitates communication and collaboration among crystallographers, researchers, and institutions nationwide. Its core objectives encompass fostering research and education, disseminating cutting-edge knowledge, and supporting the development of innovative techniques and methodologies in crystallography. The committee also actively engages in organizing conferences, workshops, and symposia to encourage scientific exchange and networking within the crystallographic community. By actively promoting the importance of crystallography across various scientific disciplines, the USNC/Cr endeavors to contribute significantly to the advancement of materials science, chemistry, physics, biology, and other related fields.
ACA: The Structural Science Society
The American Crystallographic Association (ACA) is a professional organization dedicated to advancing the science and practice of crystallography in the United States. It serves as a platform for researchers, educators, and practitioners in the field to exchange knowledge, collaborate on research, and promote the understanding of crystallography's applications across various disciplines. The ACA organizes conferences, workshops, and seminars, fostering a vibrant community of crystallographers and providing opportunities for professional development and networking. Furthermore, the association advocates for crystallography's significance in scientific discoveries, technological advancements, and its broader impact on society.
