1. Abstract In the framework of this study a new generation of SAPO STA-7 crystals has been investigated with the help of Interference Microscopy. The ability of the abovementioned technique to record intracrystalline concentration profiles during uptake/release of guest molecules revealed oddities of the system under study. In other words, these crystals have the tendency to break in the middl...
An account is presented on investigation of the effects of synthesis parameters, i.e., reaction sources, silica to alumina ratio, acid molar ratio and crystallization conditions on the crystallinity, morphology and particle size of SAPO-34. The synthesis conditions were designed to produce small particles with narrow size range. The prepared samples were characterized by XRD and SE...
Organizations have invested and continue to invest considerable resources in Information and Communication Technology (ICT). Much of this investment is made on the basis of guarantee than an expected return will occur. This study presents the results of an empirical study of the impact of ICT investment on performance at the South African Post office (SAPO). Six years of historical data, from 2...
از میان فرایندهای گوناگون جداسازی ناخالصی‌ها از گاز طبیعی، جذب بر روی جاذب جامد به علت سادگی و هزینه پایین و نیز امکان دستیابی به مقدارهای حذف بالای 2CO مورد توجه قرار گرفته است. جاذب SAPO-34 که یک غربال مولکولی است به علت اندازه حفره های همانند کربن دیاکسید و بزرگ‌تر از CH4 سبب جداسازی بالای 2...
