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 […]

Bioorthogonal metallocatalysis has opened up a xenobiotic route to perform nonenzymatic catalytic transformations in living settings. Despite their promising features, most metals are deactivated inside cells by a myriad of reactive biomolecules, including biogenic thiols, thereby limiting the catalytic functioning of these abiotic reagents. Here we report the development of cytocompatible alloyed AuPd nanoparticles with […]
