The morphology of the dark and bright regions observed by transmission electron microscopy for the Zr(64.13)Cu(15.75)Ni(10.12)Al(10) bulk metallic glass strongly depends on the ion beam parameters used for ion milling. This indicates that the ion beam could introduce surface fluctuation to metallic glasses during ion milling.

采用基于密度泛函理论的第一性原理赝势平面波计算方法,结合广义梯度近似(GGA)对Ru2Si3掺入Mn的电子结构和光学性质进行了研究.计算结果表明:掺入这种杂质使得Ru2Si3的晶胞体积均有所增大.Ru2Si3中掺入Mn时,Mn原子替换RuI位的Ru原子使得体系处于稳定态,导电类型变为p型,静态介电函数ε1(0)非常大,同时折射率n0的值变化较大,达到了17.722.

格子Boltzmann方法(LBM)在计算复杂结构物理模型时具有独特优势并在模拟两相流动过程中能够高效清晰捕捉相界面.本文介绍了基于Shan-Chen多相模型的格子Boltzmann方法的理论成果以及基于二氧化碳封存的超临界两相流的模拟研究.结果表明,Shan-Chen模型在模拟两相流时符合Laplace定律,且两相层流时的速度分布和相渗曲线均与理论值吻合.二氧化碳封存过程中,较大的注入速率在提高二氧化碳残余俘获量的同时会降低其化学俘获量.

A molecular dynamics study of the structural change differences between Au-225 and Au-369 clusters on MgO surfaces at low temperature

Chinese Physics B

The differences in structural change between Au-225 and Au-369 clusters with their (111) facets supported on MgO(100) surfaces at 5 K are studied by using molecular-dynamics simulations with the atomic interchange potentials of the Au/MgO interface. The parameters are obtained from the ab initio energies using the Chen-Mobius inversion method. Analyses of the pair distribution functions show that the two Au clusters use different deformation processes to adjust the distances between the interface atoms, owing to the misfit between the atom distances among the clusters and the substrates. The local structural changes are identified by atomic density profiles.
