Molecular-mechanochemical engin

Irrespective of the gel and stimuli nature, a molecular mechanochemical engine implies a receptor, usually located at the level of the functional groups, and a functional part, at the molecular and supramolecular level. Figure 4.10. 

The study of pharmaceutical co-crystals is also a re-emerging and exciting field of academic research in the context of crystal engineering and rational design of molecular assemblies. Most, if not all, fundamental aspects have been reviewed in this book, from the role of weak interactions in co-crystals to mechanochemical methods of synthesis, including insights into solubility and thermodynamic stability or phase diagrams of co-crystals.
