  text: Despite its relevance to a range of technological applications including nanocrystalline
    material fabrication, the sintering mechanisms of nanoparticles have not been
    well understood. It has been recognized that extrapolation from understanding
    of macro-particle sintering is unreliable for the nano-particle size regime. In
    this work, the sintering behaviour of copper nanoparticles under periodic boundary
    conditions at different temperatures and pressures was investigated by Molecular
    Dynamics simulations. It was found that smaller particle sizes, higher temperature
    and higher external pressure facilitate densification. Through a comparison with
    a two-sphere model, the governing mechanisms for many nanoparticles sintered at
    low temperature (T⩽900K) were identified to be a variety of plasticity processes
    including dislocation, twinning and even amorphization at the contact neck regions,
    due to the presence of high stresses.
