Mean SiOSi bond angles from recently published single crystal X-ray refinements of improved accuracy are used in the calculations. Good agreement between theoretical and experimental spectra as well as between the bond angles from XRD and those calculated from 29Si chemical shifts has been found ...
However, the spectra of late-stage basalts with spectral features similar to those of CE-5 samples have been interpreted as enriched in olivine in the past, while the XRD analysis of CE-5 samples shows the olivine abundance is not significant. What causes the misidentification of an HCP-domina...

XRD has identified 5 to 8 weight percent clay minerals with illite composing approximately 2/3 of the clay and the remainder being chlorite. Klinkenberg permeability ranges from 0.010 to 0.125 millidarcies. The interpreted depositional environment of the Gray Sand interval in the Willamette well is...

Calcium zincate microcrystals are successfully prepared with calcium carbonate and zinc oxide as reactants in alkaline solution without protective atmosphere. The structure and composition are analyzed by X-ray powder diffraction (XRD) analysis, thermodiffractometry, scanning electron microscope (SEM), ...
Finally, the original XRD data are reexamined and found to be insufficient to unequivocally ascribe observed behavior to that of an ordered material with a well-established and confirmed structure containing strictly interstitial oxygen anions. The hyperstoichiometric oxide PuO[sub2+x-]H[sub2]O ...
Mapping the facies for each sequence over the complete succession shows the evolution of the basin. Facies modeling, when incorporated with core, XRD, and mineral models allow for reservoir prediction and the development of completions strategies. Deposition and preservation of organic matter i...

The results obtained from this model has been compared and fitted with experimentally obtained data through XRD, RSM, PL, SEM etc. Finally, a phase diagram has been proposed to interpret the phase separation and Indium content evolution under the influence of growth temperature and precursor gas ...
