Spectroscopic Methods in Mineralogy and Geology, Frank C. Hawthorne, ed. 1988),
contained a single chapter on X-ray absorption spectroscopy which reviewed aspects of …

The two first chapters of this volume focus on the structure of magmas at different scales:
short and medium range order. A quick review of the glass literature, from the 90's or older …

Because of their importance in both the geosciences and the glass-making industry, alkali
aluminosilicate melts have been the focal point of many past studies, but despite progress …

Glassy Na‐ion solid‐state electrolytes (GNSSEs) are an important group of amorphous
SSEs. However, the insufficient ionic conductivity of state‐of‐the‐art GNSSEs at room …

Bauxite residue (BR) is a highly alkaline solid hazardous waste produced from bauxite
processing for alumina production. Alkaline transformation appears to reduce the …

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 …

The alkali-silica reaction (ASR) causes internal expansion that leads to severe concrete
degradation. The structure of the ASR products remains largely unclear, due to the limitation …

Viscosity and structure of Na/K tectosilicate glasses containing 75 and 83mol% of SiO2 have
been investigated. Viscosity increases non-linearly when K+ ions substitute Na+ ions in …

Sodium concentrations in biogenic CaCO 3 are several thousands of parts per million, and,
on a molar basis, Na is among the most abundant constituent minor element in these …

Silicate glasses are important cultural, societal, and geological materials. Geologic glasses
testify to the igneous activity of the Earth, and represent an important source of tools and …
