TL;DR: This study demonstrates for the first time the permanent disposal of CO2 as environmentally benign carbonate minerals in basaltic rocks and demonstrates that the safe long-term storage of anthropogenic CO2 emissions through mineralization can be far faster than previously postulated.
Journal ArticleDOI
Characterization of Eyjafjallajokull volcanic ash particles and a protocol for rapid risk assessment
Sigurdur R. Gislason,Tue Hassenkam,S. Nedel,Nicolas Bovet,Eydis Salome Eiriksdottir,H.A. Alfredsson,Caroline Piper Hem,Z. Balogh,Knud Dideriksen,Niels Oskarsson,Bergur Sigfússon,Gudrún Larsen,Susan L. S. Stipp +12 more
TL;DR: The physical and chemical nature of the ash was explored to determine if fears about health and safety were justified and a protocol was developed that will serve for assessing risks during a future event.
Journal ArticleDOI
Reduction of hexavalent chromium by ferrous iron: A process of chromium isotope fractionation and its relevance to natural environments
TL;DR: In this article, the authors investigated isotope fractionation during reduction of stable chromium (Cr) isotopes by Fe(II)aq in batch experiments and showed that the reduction of Cr(VI) isotope composition of solids and solution displays Rayleigh distillation with α = 0.9985.
Journal ArticleDOI
Behaviour of Fe-oxides relevant to contaminant uptake in the environment
Susan L. S. Stipp,M. Hansen,R. Kristensen,Michael F. Hochella,L. Bennedsen,Knud Dideriksen,Tonci Balic-Zunic,D Léonard,H.-J Mathieu +8 more
TL;DR: The behavior of Fe-oxides was investigated during precipitation and co-precipitation, phase transformation and dissolution, while their ability to adsorb and incorporate trace components was examined as discussed by the authors.
Journal ArticleDOI
Equilibrium Fe isotope fractionation between inorganic aqueous Fe(III) and the siderophore complex, Fe(III)-desferrioxamine B
TL;DR: In this paper, the equilibrium Fe isotope fractionation induced by organic ligand activity in experiments with solutions having coexisting inorganic Fe(III) species and siderophore complexes, Fe-desferrioxamine B (at pH 2), was determined.
