Synchrotron radiation (SR) based techniques have been utilized with increasing frequency
in the past decade to explore the brilliant and challenging sciences of actinide‐based …

Abstract Tetravalent actinides, An (IV), are usually assumed to be little mobile in near-neutral
environmental waters because of their low solubility. However, there are certain …

The transformation of 2-line ferrihydrite to goethite from supersaturated solutions at alkaline
pH≥ 13.0 was studied using a combination of benchtop and advanced synchrotron …

Wet chemistry and spectroscopic investigations were conducted to study Fe (III) uptake by
calcium silicate hydrate (C–S–H) at different Ca/Si ratios. Wet chemistry experiments were …

The uptake of niobium by hardened cement paste (HCP) and calcium silicate hydrate (CSH)
phases was investigated with 93 Nb and 95 Nb (t 1/2= 35.0 days). Structural materials used …

The mechanisms for the reduction and uptake of Tc by magnetite (Fe3O4) and mackinawite
(FeS) are investigated using X-ray absorption spectroscopy (XANES and EXAFS), in …

Fe (II) interaction with cement phases was studied by means of co-precipitation and sorption
experiments in combination with X-ray absorption fine structure (XAFS) spectroscopy …

Uptake of plutonium by Portland cement in degradation stage II was investigated in the
presence of α-D-isosaccharinic acid (ISA) under reducing conditions set by hydroquinone …

In deep geological repositories for radioactive waste, interactions of radionuclides with
mineral surfaces occur under complex geochemical conditions involving complex solution …

The behaviour of U (VI) in hyperalkaline fluid/calcite systems was studied over a range of U
(VI) concentrations (5.27× 10− 5 μM to 42.0 μM) and in two high pH systems, young and old …
