    Chiroptically active pinwheel assemblies on substrates are formed by tetrahedral gold nanoparticles from the effective ‘compression’ of a perovskite-like, low-density phase, thereby enabling the manufacture of metastructured coatings with special chiroptical characteristics as identified by photon-induced near-field electron microscopy and chirality measures.

    Sustainability requires conserving the planet’s resources so that waste products from one process become the input for another.

    • Herb Brody

  • Outlook |

    The computers, smartphones and other technologies that define modern life are creating waste across the world. A combination of technological and policy solutions could help to limit the damage.

    Reusing plastics and other materials is not enough. To achieving a circular economy, we must make less stuff to begin with.

    • Kristian Syberg

  • Outlook |

    A circular economy requires an overhaul of product design, consumption and waste management. Although recycling is dismissed by some as insufficient, it remains an essential process.

    Because open-circuit voltage deficit is greater in wide-bandgap perovskite solar cells, the authors introduce diammonium molecules to modify perovskite surface states and achieve a more uniform spatial distribution of surface potential, enabling record voltage all-perovskite tandem solar cells.

    Perovskites are promising candidates for use in next-generation light-emitting diode (LED) displays that are vivid and have high colour quality. LEDs made from particles with a perovskite nanocrystal core and an acidic shell are efficient and bright, and have a long operational half-life.

    High-temperature solutions called fluxes are widely used to synthesize solid compounds. The composition and structural properties of reaction products in a two-component flux system can now be tuned by varying the temperature and the ratio between a component of the reaction medium and a second component that serves as a ‘tuning knob’.

    Using a stable and viscosity-tunable perovskite ink, a hybrid perovskite thin-film photovoltaic device can be deposited by the screen-printing method, which exhibits higher efficiency compared with previously investigated techniques.

    Conventional manufacturing methods struggle to meet the increasing demand for microscopic and nanoscale products, because small things are difficult to manipulate. An innovative machine that uses a water–air interface to grab and manoeuvre microscopic objects might be a powerful tool in this race-to-the-smallest.

    Observations by transmission electron microscopy of deforming niobium and tungsten at low temperature shows that anomalous slip in body-centred cubic metals arises from the unusually high mobility of multi-junctions, which is a source of softening.
