  text: Tribological shearing of polycrystalline metals typically leads to grain refinement
    at the sliding interface. This study, however, shows that nanocrystalline metals
    exhibit qualitatively different behavior. Using large-scale atomistic simulations,
    we demonstrate that during sliding, contact interface nanocrystalline grains self-organize
    through extensive grain coarsening and lattice rotation until the optimal plastic
    slip orientation is established. Subsequently, plastic deformation is frequently
    confined to localized nanoshear bands aligned with the shearing direction and
    emanating from voids and other defects in the vicinity of the sliding interface.

  text: The multiply charging process of platinum cluster ions under intense field
    conditions show a strong dependence on the width of the femtosecond laser pulse.
    Increasing the pulse width from 140 to 600 fs while keeping the energy per pulse
    constant leads to an increase in the highest observed charge state z∗ of the ejected
    atoms from z∗=13 to z∗=20. This increased charging efficiency is explained by
    the evolution of the plasmon energy of the metal cluster upon the change in electron
    density during the Coulomb explosion process. Thus the time dependence of the
    charging of a cluster in an intense light field has been observed in real time.
