    Tetradymite-type materials, such as Bi2Te3, have for decades been of interest as excellent thermoelectrics near ambient temperature and have recently enabled many seminal studies on topological insulators. In this Review, we discuss the recent progress in optimizing the properties of bulk and thin-film tetradymites for such studies.

    Inorganic oxide materials are used in semiconductor electronics, ion exchange, catalysis, coatings, gas sensors and as separation materials. In this Review, we explain how polyoxometalate clusters are amenable to molecular control and can be assembled into inorganic frameworks owing to the molecular nature of their building blocks.

    Low-bandgap (<1.6 eV) polymers enable polymer solar cells to form effective tandem structures for harvesting near-infrared solar energy as well as reducing thermal loss. This Review summarizes recent progress and provides a perspective on various low-bandgap polymer-containing tandem solar cells; namely, pure polymer–polymer tandem, hybrid polymer–amorphous silicon tandem and unconventional perovskite–polymer tandem solar cells.

    The field of active matter studies how internally driven motile components self-organize into large-scale dynamical states and patterns. This Review discusses how active matter concepts are important for understanding cell biology, and how the use of biochemical components enables the creation of new inherently non-equilibrium materials with unique properties that have so far been mostly restricted to living organisms.
