  In this paper, the electron localization length was calculated numerically in a one-dimensional chain of atoms with random binary alloy. It is shown that in a one-dimensional finite-size chian of atoms, the localization length of the electron wave function decreases with increasing impurity concentration and with more increasing of the impurity concentration, the localization length becomes s...

By using binary ethanol/water mixtures, the separation performance of two improved commercial pervaporation embranes (PERVAPTM) are presented. Separation performance data are analyzed and compared as a function of operating conditions. The effect of initial feed concentration on the separation performance and the effect of feed concentration on apparent activation energy are presented. For memb...
