## Title

- title: The Atomic Observation of the Structural Change Process in Pt Networks in
    Air Using Environmental Cell Scanning Transmission Electron Microscopy

## Description

- description: 'The structural change in Pt networks composed of multiple chain connections
    among grains was observed in air at 1 atm by atomic-resolution environmental cell
    scanning transmission electron microscopy. An aberration-corrected incident electron
    probe with a wide convergence angle made it possible to increase the depth resolution
    that contributes to enhancing the signal-to-noise ratio of Pt network samples
    in air in an environmental cell, resulting in the achievement of atom-ic-resolution
    imaging. Dynamic observation on an atomic scale suggested that the structural
    change of the networks was not attributed to the surface atomic diffusion-induced
    step motion but mainly caused by the movement and deformation of unstable grains
    and grain boundaries. '
