saragow@dataone.in, www.saraxraygroup.net Keywords: Alkali halide, Metal impurity, Electronic structure, MEM, Multipole.
Multipole analysis of the structure has been performed for these two systems, with respect to the expansion/contraction of the ion involved. 1.
Introduction The distribution of electrons in the crystalline system is an interesting and important subject of research in the field of physics, chemistry, material science and Engineering.
When the system is dilute doped, it is possible to study only the average electronic structure.
The refined multipole structure factors were used for the MEM computations of the electron densities.

Properties of the samples have been characterized by X-ray diffraction (XRD) to determine the crystal structure of the sample and X-ray Fluorescence (XRF) to determine the elemental composition of the sample.
The crystal structure and phase identification of the products were determined by Panalytical X'Pert Pro PW3040 MPD X-ray Diffractometer (XRD) using Cu-Kα radiation (λ = 0.15406 nm) in the range of 20˚ to 80˚.

Therefore, modifying the structure of ZSM-5 zeolite can change the Si/Al ratio and the frame structure, decrease the carbon deposit and increase activity of the catalyst.
N2 adsorption measurement was performed on a QUADRSORB SI material physical structure determinate.
The XRD patterns of the samples are shown in Fig.1.The samples of PZSM-5, TZSM-5 and TZSM-5/AT display the characteristic peaks of MFI structure, which mean that forming method and alkali treatment does not make Zeolite structure changed significantly.

Introduction The aqueous solution polymerization is a simple process and it is easy to operate with the advocacy of current green chemistry concept.
An effective cross-linked structure will not formed, so water absorbency will be decreased.
The longer the chain is, the greater the network structure obtains.
