Summary
This micro-symposium is dedicated to the structural and microstructural analysis of materials, broadly understood through the diverse set of crystallographic tools available — including structure determination, phase analysis, texture, defects, and residual stresses — without restriction on the types of materials or fields of application.
The session aims to foster discussions on how crystallography contributes to understanding and optimizing materials by linking structure and properties across multiple length scales, from the atomic to the macroscopic. Special attention will be given to the complementarity of diffraction-based techniques with other structural and spectroscopic methods, which together enable the quantitative description of complex and often imperfect or partially amorphous systems.
This year’s invited lecture will focus on construction materials (such as concretes, geopolymers, and earthen materials), illustrating how crystallographic approaches can address major societal challenges related to decarbonization and climate resilience. This example, while specific, is intended to relaunch a broader dialogue around the crystallography of materials in general — encompassing functional and novel material systems alongside structural materials— and to highlight how crystallographic insights remain central to their performance and sustainability.
