On March 31st, the IB section of the «Real Sociedad Española de Química» invited Prof. Roxanne Kieltyka from the University of Leiden, The Netherlands, to deliver a talk at UIB. The title of her presentation was «Spatial and Temporal Control over Mechanics in Dynamic Biomaterials». We thoroughly enjoyed Roxanne’s insightful scientific talk and had the opportunity to exchange our thoughts on various topics such as squaramides, supramolecular chemistry, and chemical biology.
