The back cover picture highlights the mechanical and optical properties of a hybrid silica‐PHEMA coating on glass reinforced by using goethite nanorods in relation with the local structure at the interface. We demonstrate the possibility to finely tune the final mechanical properties by adjusting the coating silica content. In this hybrid nanocomposite, goethite particles exhibit interesting stress relaxation functions, which prevent crack formation in the films whilst reaching high silica content in the hybrid matrix. Details are discussed in the article by N. Chemin, C. Chanéac et al. on p. 2675 ff.
