HRTEM microcrystalline opal chert porcelanite Monterey Formation California
2012/4/9
Microcrystalline opal wasinvestigated using low-dose transmission electron microscopy (TEM) methods to identify microstructural characteristics and possible phase-transforma-tion mechanisms that accom...
Effect of Heating on Microcrystalline Synthetic Goethite
Crystallite size Goethite Microstrain Mossbauer spectroscopy Thermal treatment X-ray powder diffraction
2011/11/25
Abstract: The effect of heating synthetic microcrystalline goethite at 60°, 80°, and 105°C was studied by X-ray powder diffraction, electron microscopy, weight-loss measurements, and Mössbauer sp...
Influence of Glycine on Cu2+ Adsorption by Microcrystalline Gibbsite and Boehmite
Adsorption Boehmite Copper Electron spin resonance Gibbsite Glycine Hydrolysis
2012/2/2
The adsorption of Cu2+ on microcrystalline gibbsite and boehmite from aqueous solutions having 2/1 and 5/1 glycine/Cu ratios has been studied using electron spin resonance (ESR). The presence of glyci...
Cu2+ Interaction with Microcrystalline Gibbsite. Evidence for Oriented Chemisorbed Copper Ions
Adsorption Chemisorption Copper Electron spin resonance Gibbsite Infrared spectroscopy
2011/11/25
Abstract: The ability of a high surface-area gibbsite to adsorb Cu2+ was studied using a Cu2+ ion-selective electrode, electron spin resonance, infrared spectroscopy, and electron microscopy. The gibb...
An Analysis of X-Ray Diffraction Line Profiles of Microcrystalline Muscovites
X-Ray Diffraction Line Profiles Microcrystalline Muscovites Analysis
2012/2/20
Previous studies of the line profiles of the basal reflections of microcrystalline muscovites were refined by an adaptation of the method developed by Maire and Méring. In order to evaluate the variat...
