Thickness and Surface Characteristics of Colloidal 2:1 Aluminosilicates Using an Indirect Fourier Transform of Small-Angle X-ray Scattering Data
Illite Indirect Fourier Transform Montmorillonite SAXS Thickness
font style='font-size:12px;'>
2011/12/5
Abstract: An indirect Fourier transformation applied to small-angle X-ray scattering data has been used to determine the thickness and surface properties of two common clay minerals. For an illite sys...

Light Scattering Study on Sol-Gel Transformation of SiO2 Colloid at Extremely High Concentrations
Light Scattering Study SiO2 Colloids Sol-gel Transformation
font style='font-size:12px;'>
2011/12/8
Abstract: Ludox SiO2 sols with a reasonably uniform size of 12 nm and in the high concentration of 10 to 40 wt% were transformed to gels by lowering the pH. The process from sol to gel, followed by li...
Full multiple scattering calculations of the X-ray absorption near edge structure at the magnesium K-edge in pyroxene

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...
Particle Shape versus Coherent Scattering Domain of Illite/Smectite: Evidence from HRTEM of Dolna Ves Clays
Coherent scattering domain Fundamental particle HRTEM Illite/Smectite Mixed-layer crystal
font style='font-size:12px;'>
2011/12/27
Fundamental particle thickness measurements of Dolná Ves hydrothermal illite/smectite (I/S) samples confirmed earlier findings regarding the content of fixed cations in illite interlayers (ca. 0.9/O10...

Study of a Commercial SiO2 Sol and Gel by Small Angle X-ray Scattering: Effect of Sample Thickness and Interpretation by Means of Smoluchowski Scheme
Dependence of Sample Thickness Ludox HS SiO2 SAXS Smoluchowski Scheme Structure in sol
font style='font-size:12px;'>
2011/12/23
Abstract: Ludox HS SiO2 sols at high concentrations show a peak in small angle x-ray scattering (SAXS) reminiscent to a “structure.” The appearance of such a peak was found to depend crucially on the ...
