    • Linear grain growth kinetics and rotation in nanocrystalline Ni 

      Farkas, Diana; Mohanty, S.; Monk, J. (American Physical Society, 2007-04-20)
      We report three-dimensional atomistic molecular dynamics studies of grain growth kinetics in nanocrystalline Ni. The results show the grain size increasing linearly with time, contrary to the square root of the time kinetics ...
    • Nanotwinned fcc metals: Strengthening versus softening mechanisms 

      Stukowski, A.; Albe, K.; Farkas, Diana (American Physical Society, 2010-12-01)
      The strengthening effect of twins in nanocrystalline metals has been reported both in experiment and simulation. While twins are mostly considered as effective barriers to dislocation slip transfer, they can also provide ...
    • Thermal transport in composites of self-assembled nickel nanoparticles embedded in yttria stabilized zirconia 

      Shukla, Nitin C.; Liao, Hao-Hsiang; Abiade, Jeremiah T.; Murayama, Mitsuhiro; Kumar, Dhananjay; Huxtable, S. T. (AIP Publishing, 2009-04-01)
      We investigate the effect of nickel nanoparticle size on thermal transport in multilayer nanocomposites consisting of alternating layers of nickel nanoparticles and yttria stabilized zirconia (YSZ) spacer layers that are ...
