The availability of synchrotron radiation (SR) to the scientific community has literally
revolutionized the way X-ray science is done in many disciplines, including low temperature …

The valence and conduction bands of am-and γ-Al2O3 films grown by the atomic layer
deposition technique were studied simultaneously in identical experimental conditions using …

Heteroatoms in zeolites provide them their catalytic activity. The silicon atom is always
tetrahedrally coordinated and its valence IV, those of the heteroatoms much more varied …

The effect of Al and of pH on the structure of calcium silicate hydrate (CSH), the most
important hydration product in Portland and blended cement, was studied at Ca/Si~ 1.0. The …

Tecto-aluminosilicate and peraluminous glasses have been prepared by conventional and
laser heating techniques, respectively, in the CaO-Al2O3-SiO2 system. The structure of …

Abstract Ancient Roman syntheses of Al-tobermorite in a 2000-year-old concrete block
submerged in the Bay of Pozzuoli (Baianus Sinus), near Naples, have unique aluminum-rich …

Application of in situ X-ray absorption near-edge spectroscopy (XANES) at the Al K-edge
provides unique insight into the flexibilty of the aluminum coordinations in zeolites as a …

The rheology of modern Portland cement (PC) concrete critically depends on the correct
dosage of gypsum (calcium sulfate hydrate) to control the hydration of the most reactive …

Soil represents the largest reservoir of terrestrial organic C, and plays a critical role in global
C cycling. In light of predicted climate change and a more unified approach to mitigate …

X-ray absorption near-edge structure (XANES) spectroscopy is the ideal non-destructive
technique for characterizing and quantifying S species in compositionally complex natural …
