  • Electrolyte gating of complex oxides enables substantial control of electronic phase transitions, allowing electrical control of complex phenomena. Here, the role of both electrostatic and electrochemical mechanisms in this process is elucidated.

    • Chris Leighton
    Perspective
  • This Perspective explores the history and usage of the concept of oxidation state, its relation to atomic charge and bonding, and opportunities that arise from applying this analysis to systems with mixed valence or correlated electrons.

    • Aron Walsh
    • Alexey A. Sokol
    • C. Richard A. Catlow
    Perspective
  • This Perspective describes the recent advances in understanding and controlling the properties of single-wall carbon nanotubes as well as the progress towards the fabrication of new electrically driven single-photon sources.

    • X. He
    • H. Htoon
    • C. Voisin
    Perspective
  • This Perspective explores the optical, mechanical and thermal properties required to successfully design an ultralight spacecraft that can reach Proxima Centauri b, which is the goal of the Starshot Breakthrough Initiative.

    • Harry A. Atwater
    • Artur R. Davoyan
    • Joeson Wong
    Perspective
  • Catalysts for CO2 photo- or electroreduction must balance activity, selectivity and efficiency. Here, the authors discuss the use of metal–organic frameworks for these processes and the role reticular chemistry may play in designing new catalysts.
