VII Latin American Crystallographic Association (LACA) and the XXVII Brazilian Crystallographic Association (ABCr)

We are delighted to invite you to the VII Latin American Crystallographic Association (LACA) and the XXVII Brazilian Crystallographic Association (ABCr) joint meeting, to be held from October 13–17, 2025 , in Fortaleza, Brazil. This important event will showcase recent developments and innovations in crystallographic and structural sciences, providing extensive opportunities for scientific exchange and collaboration.

Scientific Highlights Include:

- Plenary and Keynote Lectures: Presented by internationally recognized experts, these sessions will cover groundbreaking research and emerging trends in crystallography and structural sciences.

- Thematic Microsymposia: Focused on critical topics such as structural biology, quantum crystallography, pharmaceuticals and medicinal chemistry, materials science, coordination compounds and MOFs, heritage and industrial applications, neutron and synchrotron techniques, and emerging computational methods (including machine learning and AI).

- Poster Sessions and Interactive Discussions: Offering opportunities to discuss research results, methodologies, and foster collaborations among participants.

Pre-meeting LACA-ABCr School (October 13–14, 2025):

Fragment Screening by X-ray Crystallography: Targeted at structural biologists and researchers in drug discovery, focusing on fragment-based drug discovery methods.

Small Molecule Structure Determination: Designed for researchers in chemical crystallography and materials science, including practical training in the use of the Cambridge Structural Database (CSD).


I Latin American Powder Diffraction Conference (LAPDiC)
October 13–14, 2025
In parallel with the LACA-ABCr School, the first LAPDiC conference will address current advances and applications in powder diffraction techniques, emphasizing X-ray, neutron, and electron diffraction methods. Topics will include:

Powder diffraction in pharmaceuticals and materials science

Phase identification and quantification
Diffraction under non-ambient conditions
Structure determination and refinement methods from powder data
In situ and operando diffraction studies
Advanced instrumentation and software tools

LAPDiC School (October 11–12, 2025)
Prior to the conference, the LAPDiC School will provide hands-on practical training and theoretical insights on the Pair Distribution Function (PDF) method. This intensive two-day training session will be delivered by international and regional experts, preparing participants with practical skills in data collection, analysis, and interpretation.

Registration and Abstract Submission:
Abstract Submission Opens: April 1, 2025
Early-Bird Registration and Bursary Deadlines: To be announced soon

We encourage early submission and registration, as limited bursaries will be available to support inclusive participation and geographical diversity.
