low oxygen partial pressure make the material desirable for air separation and gas purification. High purity nitrogen gas was produced with the YBCO molecular sieves in the air separation and gas...Studies on Oxygen Characteristics of YBa2Cu3O7-x and Its Applications to Air Separation and Gas Purification Guo Yiqun1,Gao Zhishuang2,Lu Hongxia2,Yang Delin2,Mo Jiong2,Hu Xing2 (1.Department......
. For the Hessian-base velocity Verlet integrator, the gradient is needed at the beginning and end of each time velocity Verlet step. These gradients are approximated from a 5th order high-dimensional interpolation... of moving atoms in direct dynamics simulations. We employ a monodromy matrix to propose a tool for evaluating the accuracy of integrators in the trajectory calculation. We choose a general velocity......
