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...
