Abstract
© 2021 American Chemical Society. All rights reserved.Aqueous droplets covered with amphiphilic Janus Au/Fe3O4 nanoparticles and suspended in an organic phase serve as building blocks of droplet-based electronic circuitry. The electrocatalytic activity of these nanoparticles in a hydrogen evolution reaction (HER) underlies the droplet's ability to rectify currents with typical rectification ratios of ∼10. In effect, individual droplets act as low-frequency half-wave rectifiers, whereas several appropriately wired droplets enable full-wave rectification. When the HER-supporting droplets are combined with salt-containing "resistor"ones, the resulting ensembles can act as AND or OR gates or as inverters.
