Synchrotron based Transmission x-ray microscopy reveals smectite fine structure in an aqueous environment
Synchrotron Transmission x-ray microscopy reveals smectite fine structure aqueous environment
2012/3/30
The unusual behaviour of smectites, the ability to change volume when wetted (swelling) or dried (shrinking), make soil containing smectites very unstable and hazardous for the building industry due t...
MINERALOGICAL ABUNDANCES AS DETERMINED BY X-RAY DIFFRACTION IN SELECT SAMPLES OF THE UPPER FLORIDA AQUIFER
MINERALOGICAL ABUNDANCES X-RAY DIFFRACTION FLORIDA AQUIFER
2011/11/11
Analysis of 53 bulk powders derived from various rocks of the Upper Floridan Aquifer reveal calcite, dolomite/ankerite, quartz, apatite, and smectite to be the dominant minerals, with the clay and apa...
TRACE ELEMENT DETERMINATIONS COMPARED WITH X-RAY DIFFRACTION RESULTS OF BROWN CLAY IN THE CENTRAL PACIFIC
BROWN CLAY X-RAY DIFFRACTION THE CENTRAL PACIFIC
2011/11/8
Prior to DSDP Leg 17, no sites drilled in the central Pacific had continuously cored a thick section of pelagic brown clay. On Leg 6 several sites were drilled through brown clay, but poor recovery du...

In-Situ Identification of Palygorskite in Maya Blue Samples Using X-Ray Powder Diffraction
Palygorskite X-Ray Powder Diffraction Maya Blue Samples
2011/11/4
In spite of the abundance of colors found in the murals and other objects that correspond to the Classic Mayan period (600-900 A.D.), a peculiar hue captured the interest of researchers. The most well...
Identification of Iron Rusts on Rail by X-Ray Diffraction and Vibrational Analysis
Corrugation Rail Railway Raman Scattering Submarine Tunnel Vibrational Spectroscopy X-Ray Diffraction (XRD)
2011/12/16
A periodical unevenness of the running surface of rails is formed on ascending slope of submarine railway tunnel. One of the causes has been concluded due to the combination of a low friction and whee...
