    Biological tissues are extremely water rich but remain mechanically stiff, behaviour that is difficult to recapitulate in synthetic materials. Here the authors design a hydrogel/sponge hybrid material driven by a self-organized network of cyano-p-aramid nanofibres that combines these properties for biofunctional materials.

    Inspired by the observed coherent interface between hexagonal α-Fe2O3 and tetragonal fluorine-doped SnO2, an oxygen sublattice-matching paradigm is proposed to grow textured films on lattice-mismatched substrates. Through assessing the similarity of Voronoi cells for sublattices, this approach offers opportunities to synthesize (semi)coherent heterostructures and textured films.

    Depositing textured functional materials on transparent conducting oxides remains a challenge. We demonstrate the formation of a coherent interface between a set of functional oxides and fluorine-doped-tin-oxide-based transparent conducting oxide substrate despite the lattice mismatch, owing to dimensional and chemical matching of oxygen sublattices at the interface.

    Oxidation can degrade the properties and functionality of three-dimensional bulk metallic glasses. However, the formation of percolating oxide networks in metallic glass nanotubes or nanosheets can induce interesting properties, such as a recoverable strain of 10–20% and elastic modulus of 20–30 GPa, which are rarely observed in their bulk counterparts.

    The transmission spectrum of single-molecule junctions provides fingerprint information on the charge-transport properties. A technique called single-molecule photoelectron tunnelling spectroscopy has been developed that enables mapping of the transmission spectrum beyond the highest occupied molecular orbital (HOMO)–lowest unoccupied molecular orbital (LUMO) gap at room temperature and can be used to explore the energy-dependent charge transport through single-molecule junctions.
