L'Association Européenne de Cristallographie (ECA) organise depuis 2021 des "webinaires déjeuner". Les groupes d'intérêt spéciaux (SIG) et les groupes d'intérêt général (GIG) de l'ECA organisent à tour de rôle un webinaire adapté à la communauté des cristallographes au sens large. Le 35ième webinaire sera diffusé le 27 mars 2025. Le thème de ce webinaire est From liquid ingredients to crystalline smart materials (Alessia Bacchi, University of Parma, Italy). Inscriptions ici.
Some ingredients relevant to human health, environment protection, and nutrition are liquid at ambient conditions. Crystal engineering is a powerful tool to design materials with high technological added value to address health and environment protection through mild and nature friendly components and mechanochemical methods. In fact mechanochemical cocrystallization has proven to be a powerful method to store and control the release of liquid ingredients in the environment, by engineering intermolecular interactions which strengthen or weaken the tendency of the ingredient to be retained inside the solid matrix. Here we show some proofs of concept that a rational design of crystalline materials capable to store and release Liquid Ingredients guests is feasible, and that the release profile can be related to the solid state arrangement of the material, offering a strong and rational tool to afford a vast range of materials capable of controlled release of L-I.
