El Dr. Rafel Prohens i Anna Portell, tècnics de la Tecnologia de Polimorfisme i Calorimetria, han publicat “Single-Stranded Molecular Helical Assembly from a Self-Complementary Squaramide Compound” a la revista Crystal Growth & Design, la qual pertany a l'American Chemical Society i és la revista d'Enginyeria Cristal.lina amb major índex d'impacte (4,689). El resum de l'article és el següent: "A new helical crystal structure of a disquaramide compound has been solved by means of direct methods from powder X-ray diffraction data. It contains a racemic mixture of alternating clock/anticlock wise rotating helices which are formed through an unprecedented combination of strong squaramide−squaramide and amine−phenol interactions, both in a head-to-tail fashion." | |
