IMAGE (IMAGE) Kyoto University Caption This image offers an abstract visual representation of graphene oxide sheets (black layers) embedded with nanodiamonds (bright white points). The nanodiamonds exert long range electrostatic forces (nebulous white circles) which stabilize the sheets even in humid conditions creating a promising membrane material for hydrogen purification.
