Low-Temperature Rapid Synthesis and Superconductivity of Fe-Based Oxypnictide Superconductors
, 2010 we were able to develop a novel method to synthesize Fe-based oxypnictide superconductors. By using LnAs and FeO as the starting materials and a ball-milling process prior to solid-state sintering, Tc as high as 50.7 K was obtained with the sample of Sm ...

Molecular dynamics of comminution in ball mills [PDF]
The European Physical Journal B, 2000 We Investigate autogenous fragmentation of dry granular material in rotating cylinders using two-dimensional molecular dynamics. By evaluation of spatial force distributions achieved numerically for various rotation velocities we argue that comminution occurs mainly due to the existence of force chains.
