CA AND NA ENVIRONMENTS IN NA2O-CAO-AL2O3-SIO2 GLASSES: INFLUENCE OF CATION MIXING AND CATION-NETWORK INTERACTIONS

Cormier L.; Neuville D.R. (2004)

X-ray absorption spectroscopy at Ca and Na K-edges and Molecular Dynamics (MD) simulations are used to investigate the Ca and Na environment in soda lime aluminosilicate glasses. Both X-ray Absorption Near Edge Structure ...
SITE OCCUPANCIES BY IRON IN NONTRONITES

Gates W.P.; Slade P.G.; Manceau A.; Lanson B. (2002)

Twelve nontronites and two ferruginous smectites have been characterized with respect to Fe3+ occupancy of tetrahedral sites. The techniques used were near infrared, Fe-K X-ray absorption near-edge and X-ray absorption ...
THEORETICAL STUDIES ON POSSIBLE SULFUR OXIDES WITH + 2 OXIDATION STATES IN AQUEOUS SOLUTION

Tossell J.A. (1997)

In the oxidation of sulfide to sulfate a number of different intermediate products are commonly observed, but products with S oxidation states of + 2 seem generally to be absent. Recently Vairavamurthy and Zhou (hereafter ...
