Es una portada de revista, actividad de difusión., A multifunctional graphene conjugate was designed for cancer treatment, as reported by E. Miyako, A. Bianco, and co-workers in their Communication on page 14034.

Portada de revista, actividad de difusión., The Cover Feature illustrates the improvement in the supercapacitive performance of CoAl layered double hydroxides (LDHs) after enlarging their interlayer space with anionic surfactants. This enhancement in the energy storage is ascribed to the increase in the electrochemical surface area (ECSA), the higher electrolyte diffusion, and the partial aluminum dissolution.

This cover illustrates how carbon nano-onions can be intercalated with potassium atoms through surface defects by means of thermal heating. This reductive route allows the efficient covalent functionalization with electrophiles such as alkyl iodides.

Portada de revista, actividad de divulgación., The Cover Feature shows how phosphorene can catalyse different radical additions to alkenes. These catalysts have an initial turnover frequency up to two orders of magnitude higher than representative state–of–the–art metal complex catalysts at room temperature. In their Full Paper, M. Tejeda-Serrano et al. describe how the electron–richness of the 2D material, either phosphorene or graphene, parallels the catalytic activity of different low-valence iron compounds as metal catalysts. These results showcase the advantages of substituting metals by p–block main-group elements not only because of their positive economic and ecological fingerprint, but also because of their higher catalytic efficiency in some organic reactions, which opens the door for cross–fertilization between 2D materials and metal catalysts in organic synthesis.

The application of external magnetic fields to NiFe–graphene nanocomposites during the galvanostatic charge/discharge cycles induces a dramatic metal phase segregation, forming nanometric metal clusters of Ni with an outstanding electrochemical activity. This metal segregation leads to an enhancement in the capacitance of the nanocomposite, as described by Gonzalo Abellán, Eugenio Coronado, and co-workers in article number 1900189.
