  - "Dielectric particles of the same material exchange electrical charge during collisions
    or sliding contacts, yet the underlying charge-exchange mechanism is still not
    understood. The fact that particles can become highly charged as a result of this
    effect has significant consequences for many settings, both in nature and industry,
    such as thunderstorms, volcanic eruptions, particle aggregation during meteorite
    and planet formation, and the clogging of industrial granular systems. Toward
    understanding these systems, great efforts have been made to develop precise in
    situ measurements for particle charge, e.g., to determine ensemble charge distributions
    or measure exchange during individual contacts. Here, we present experimental
    results concerning the particle size scaling of the stationary-state charge distributions
    of oxide particles in the sub-millimeter range. We measure the charge distributions
    for large ensembles of monodisperse ZrO2:SiO2 composite spheres, ranging from
    172 to 545µ⁢m in diameter. These distributions are non-Gaussian and collapse to
    a single master curve when plotted as functions of the surface charge density
    Σ=\U0001D45E/4⁢\U0001D70B⁢\U0001D4452. X-ray fluorescence and atomic force microscopy
    measurements show that the differences in the measured charge distributions are
    not due to variations in chemical composition or surface roughness, but rather
    to size alone. Our findings provide constraints on microscopic models for charge
    exchange, namely that they should lead to steady-state distributions that are
    non-Gaussian and scale in a specific way with particle size.@eng"
