  text: In this work, we simulate the response of two Cu nanoparticles colliding at
    different approaching rates at room temperature by MD. For small nanospheres,
    the formation of single twins is favored at high approach rates, whereas larger
    nanospheres mainly deform by dislocation slip. For small nanocubes with large
    {100} flat surfaces, however, a dislocation-free direct geometrical conversion
    process that leads to five-fold twinning dominates except at highly retarded approaching
    rates. For larger nanocubes, single twin formation is the governing plasticity
    mechanism. The probability for plastic deformation by dislocation slip or twinning
    is attributed to the abundance of surface steps, which act as sites for dislocation
    nucleation.
