## Description

- description: Graphene-graphene oxide (GO) hybrid liquid cells (LCs) for liquid-phase
    scanning transmission electron microscopy (STEM) were fabricated using a facile
    method with commercial graphene on a polymethyl methacrylate sheet and GO on a
    TEM grid. LCs containing Pt nanoparticles (NPs) and pure water were efficiently
    produced and observed via STEM. Their composition and thickness were characterized
    by STEM-electron energy-loss spectroscopy. High-resolution (HR) STEM revealed
    slow-moving Pt NPs’ atomic structures and fast-moving single Pt atoms at the LC’s
    thin edges. Minimal damage during HR STEM indicated stable LCs because of their
    excellent electrical and thermal conductivities and radiolysis species scavenging
    ability.
