Full multiple scattering calculations of the X-ray absorption near edge structure at the magnesium K-edge in pyroxene
Full multiple scattering calculations X-ray absorption magnesium K-edge
2012/3/31
We present a comparison between XANES experiments and full multiple-scattering cal-culations at the magnesium K-edge for two pyroxenes, diopside and enstatite, for which Mg atoms are only in the M1 si...
27Al MAS NMR and Aluminum X-ray Absorption Near Edge Structure Study of Imogolite and Allophanes
Allophane Aluminum Imogolite NMR XANES
2011/12/29
This paper compares the results of 27Al nuclear magnetic resonance spectroscopy (NMR) and Al-K-edge X-ray Absorption Near Edge Structure (XANES) of natural imogolite and allophanes and some crystallin...
Analysis and Implications of the Edge Structure of Dioctahedral Phyllosilicates
Celadonite Edge structure Illite Muscovite Octahedral site Phengite
2012/1/9
Crystal growth theory was applied to describe edge sites of phyllosilicates. Three face configurations were found to exist. One face has one tetrahedral site per tetrahedral sheet and two octahedral o...
