    Polyoxometalate clusters have been assembled into two-dimensional ‘clusterphene’ layers that are held together by coordination to lanthanide ions and electrostatic interactions with quaternary ammonium cations. The resulting materials resemble graphene sheets on account of their uniform hexagonal pores and are shown to catalyse epoxidation reactions due to their in-plane electron delocalization.

    The deposition of noble metals onto two-dimensional transition metal dichalcogenides is crucial for practical applications, including in catalysis and sensing, yet this process has remained difficult to control. Now, gold and silver have been shown to grow on colloidal transition metal dichalcogenide nanosheets into either atomically thin layers or nanoparticles whose sizes and morphologies depend on the relative strengths of the interfacial noble metal–chalcogen bonds.

    Isolating nanoscale species in liquids permits their scalable manipulation, enabling numerous fundamental and applied processes. Thus, achieving true dissolution of 2D materials is particularly desirable. Now, ionic salts of a range of important layered materials have been shown to spontaneously dissolve, yielding solutions of charged, monodisperse, undamaged and easy-to-manipulate 2D nanosheets.

    Crystals grow from nuclei. In systems where nuclei are nanometre-sized and form quickly, it is difficult to determine the mechanism of their formation. Now, through in situ TEM, the demixing of a supersaturated aqueous gold solution into metastable gold-poor and gold-rich liquid phases is observed, the latter yielding stable clusters that become nuclei for nanocrystal growth.

    Controlling the morphology and composition of hybrid nanostructures is desirable for applications, but it has proven challenging to precisely combine different nucleation sites and growth modes. Now, three types of hierarchical 1D/2D nanostructures have been prepared by selectively growing semiconductor nanorod arrays (CdS or CdSe) on the different facets of hexagonal nanoplates.
