Anisotropy in Molecular-Scaled Growth Kinetics at Ice−Water Interfaces
The Journal of Physical Chemistry B, 1997Co-Authors: Hiroki Nada, Yoshinori FurukawaAbstract:Molecular dynamics simulations of ice−water interfaces at the supercooling state were performed to elucidate the anisotropic Growth Kinetics. The simulations were carried out for two kinds of interface orientations, namely, an ice(0001)−water and an ice(1010)−water interfaces. It should be emphasized that not only the interface structures but also the Growth Kinetics are completely different between the interfaces. Furthermore, we analyzed the development of the translational order and the orientational order for the molecular arrangement during the Growth. The results suggest that the translational order of the arrangement develops in advance of the orientational order for both interfaces.

Anisotropic Growth Kinetics of ice crystals from water studied by molecular dynamics simulation
Journal of Crystal Growth, 1996Co-Authors: Hiroki Nada, Yoshinori FurukawaAbstract:Ice{0001}water and ice{1010}water interfaces were studied by means of molecular dynamics simulation. The anisotropy in the Growth Kinetics, that is, the difference in the Growth Kinetics between the interfaces was observed in the molecular level for the first time; the Growth for the ice{0001}water interface occurred by the Kinetics of layer by layer, and that for the ice{1010}water interface occurred by the Kinetics of collected molecule process. Moreover, the molecular-scaled structures of the interfaces were investigated. As a result, it was made clear that the structure of the ice{0001}water interface was smooth, but that of the ice{1010}water interface was rough. Finally, the relationship between the anisotropic interface structures and the anisotropic Growth Kinetics was discussed.

Correlation of thermodynamics and grain Growth Kinetics in nanocrystalline metals
Acta Materialia, 2006Co-Authors: Xiaoyan Song, Jiuxing Zhang, Keyong Yang, Guoquan LiuAbstract:We investigated the correlation of thermodynamics and grain Growth Kinetics of nanocrystalline metals both theoretically and experimentally. A model was developed to describe the thermodynamic properties of nanograin boundaries, which could give reliable predictions in the destabilization characteristics of nanograin structures and the slowing down of grain Growth Kinetics at a constant temperature. Both the temperature-varying and isothermal nanograin Growth behaviors in pure nanocrystalline Co were studied to verify the thermodynamic predictions. The experimental results showing that discontinuous nanograin Growth takes place at a certain temperature and grain Growth rate decreases monotonically with time confirm our thermodynamics-based description of nanograin Growth characteristics. Therefore, we propose a thermodynamic viewpoint to explain the deviation of grain Growth Kinetics in nanocrystalline metals from those of polycrystalline materials.
