Radioactive waste vitrification has been carried out industrially in several countries for
nearly 40 years. Research into the formulation and long term behavior of high and …

We derive a novel method for determining the oxidation state of a magma as zircon
crystallized, with a standard error of±0· 6 log unit ƒO2, using ratios of Ce, U, and Ti in zircon …

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 …

In the 16 years since the Sedona Conference on the behaviour of trace elements in silicate
systems, numerous studies providing new data have filled many of the gaps in knowledge of …

In oxidizing environments, the toxic and radioactive element uranium (U) is most soluble and
mobile in the hexavalent oxidation state. Sorption of U (VI) on Fe-oxides minerals (such as …

We have investigated the adsorption of the uranyl ion (UO22+) in contact with amorphous
silica (SiO2), γ-alumina (Al2O3), and montmorillonite surfaces in the pH range of 3.1–6.5 …

U, Np, and Pu LII, III-edge X-ray absorption fine structure (XAFS) spectra were collected for
the UO22+, NpO2+, Np4+, and Pu3+ ions as a function of chloride concentration in aqueous …

By 1911, the atomic weight of uranium had been refined to 238.5 (Gmelin, vol. A2, 1980a).
The natural isotope 235 U was discovered in 1935 by mass spectrometry. The artificial …

Isobaric and isothermal experiments were performed to investigate the effect of melt
composition on the partitioning of trace elements between titanite (CaTiSiO5) and a range of …

Defining the molecular-scale structure and dynamics of silicate melts has been a long-term
goal of inorganic geochemists, igneous petrologists, ceramists, glass technologists, and …
