  text: Models for same-material contact electrification in granular media often rely
    on a local charge-driving parameter whose spatial variations lead to a stochastic
    origin for charge exchange. Measuring the charge transfer from individual granular
    spheres after contacts with substrates of the same material, we find instead a
    “global” charging behavior, coherent over the sample’s whole surface. Cleaning
    and baking samples fully resets charging magnitude and direction, which indicates
    the underlying global parameter is not intrinsic to the material, but acquired
    from its history. Charging behavior is randomly and irreversibly affected by changes
    in relative humidity, hinting at a mechanism where adsorbates, in particular,
    water, are fundamental to the charge-transfer process.

  text: By rigorously accounting for mesoscale spatial correlations in donor/acceptor
    surface properties, we develop a scale-spanning model for same-material tribocharging.
    We find that mesoscale correlations affect not only the magnitude of charge transfer
    but also the fluctuations—suppressing otherwise overwhelming charge-transfer variability
    that is not observed experimentally. We furthermore propose a generic theoretical
    mechanism by which the mesoscale features might emerge, which is qualitatively
    consistent with other proposals in the literature.
