2D materials display exciting properties in numerous fields, but the development of applications is hindered by the low yields, high processing times, and impaired quality of current exfoliation methods. In this work we have used the excellent MW absorption properties of MoS2 to induce a fast heating that produces the near-instantaneous evaporation of an adsorbed, […]

  • Comments off

The paper puts forward the concept of double redox electrochemical capacitor operating in an aqueous electrolyte. It combines the redox activity of sulphur from Bi2S3 nanocrystals combined with the reactions of iodides which take place at opposite electrode. This combination effectively boosts the capacitance (275 F g-1), and the energy density of the device thanks […]
