  • Micro-supercapacitors offer the advantage of high power density over lithium batteries and high energy density over electric capacitors, but integration of these advantages is yet to be achieved. Wu et al. develop a graphene-based in-plane micro-supercapacitor with ultrahigh power and energy densities.

  • Chemical functionalization of graphene is a useful method for modulating its properties, although this is limited by a lack of control and resulting in poorly defined structures. Here the authors report the atomically precise chlorination of nanographenes and apply the methods to graphene nanoribbons.

  • A linear energy–momentum relation of graphene results in a high direct-current electron mobility, but this is not necessarily true at terahertz frequencies. Here, the authors show that its ultrafast conductivity is dependent on a highly nonlinear interplay between heating and cooling of the electron gas.

  • Two-dimensional materials can enable a new generation of flexible and printed electronics suitable for light-weight, low-power, sustainable and cost-effective field-effect transistors. This Review surveys solution-processed transistors based on 2D materials, discussing their performance, limitations and future perspectives.
