    A lithographic patterning and release method is used to create a dense, fluctuating, Brownian system of mobile colloidal kite- and dart-shaped Penrose tiles over large areas that retains quasi-crystalline order.

    Cold-drawing of multimaterial fibres consisting of a brittle core embedded in a ductile polymer cladding results in controllable fragmentation of the core to produce uniformly sized rods parallel to the drawing direction for cylindrical geometries and narrow, parallel strips perpendicular to the drawing direction for flat geometries.

    Two-dimensional titanium carbide has been produced by etching out aluminium in a lithium fluoride and hydrochloric acid mixture; it is hydrophilic and mouldable like clay and has excellent volumetric capacitance and cyclability, properties that are desirable for portable electronics.

    The unusual ordering of quasicrystals can be induced in thin films of a regular crystalline material; here a two-dimensional quasicrystal has been achieved by growing thin films of the perovskite barium titanate on an appropriately oriented crystalline platinum substrate.

    The enhanced reversibility (stable transition temperature even at high strain under a solid-to-solid phase transition), low hysteresis and unusual riverine microstructure (ranging through thermal cycles) of the martensitic material Zn45Au30Cu25 makes it attractive for applications from eco-friendly fridges to medical sensors.

    A method of producing perovskite-sensitized solar cells by sequential — as opposed to single-step — deposition of the perovskite’s components onto a nanoporous titanium oxide film allows for greater reproducibility of device performance and a record power conversion efficiency of 15 per cent.

    Molten oxide electrolysis is considered a promising route for extractive metallurgy with much reduced carbon dioxide emissions relative to traditional routes; now a new chromium-based alloy has been developed for use as an oxygen evolving anode that remains stable in the high-temperature corrosive conditions found during iron production via electrolysis.

    Topologically distinct colloidal particles introduced into a nematic liquid crystal align and generate topology-constrained three-dimensional director fields and defects in the liquid crystal fluid that can be manipulated with a variety of methods, opening up a new area of exploration in the field of soft matter.

    Quantum simulation is a promising tool for navigating the complex world of many-body physics. The technique has now been employed to simulate a frustrated network of three quantum magnets by using trapped ions.

    In the search to reduce our dependency on fossil-fuel energy, new plastic materials that are less dependent on petroleum are being developed, with water-based gels — hydrogels — representing one possible solution. Here, a mixture of water, 3% clay and a tiny amount of a special organic binder is shown to form a transparent hydrogel that can be moulded into shape-persistent, free-standing objects and that rapidly and completely self-heals when damaged.
