Testing the Suitability of Zerovalent Iron Materials for Reactive Walls
- Environmental Chemistry
Zerovalent iron (ZVI) has been proposed as reactive material in permeable in situ walls for contaminated groundwater. An economically feasible ZVI-based reactive wall requires cheap but efficient iron materials. From an ...
Comments on: "The effect of substituent groups on the reductive degradation of azo dyes by zerovalent iron" by M. Hou, et al. [J. Hazard. Mater. 145 (2007) 305]
- Journal of hazardous materials
This letter discusses possible improvements in experimental conditions to enable a purposeful discussion on the effect of substituent groups on the reductive degradation of azo dyes by elemental iron (Fe0) in a recent ...
Verhüttungsexperimente mit Chalkopyrit-Erz nach Vorbildern aus dem bronzezeitlichen Ostalpenraum und Nepal
- Experimentelle Archäologie in Europa
Smelting experiments with chalcopyrite ore based on records of the Bronze Age Eastern Alps and Nepal. During the summer of 2018, the German Mining Museum Bochum (DBM) and the Roman-Germanic Central Museum (RGZM) conducted ...
Crystal structure of a calcium(II)–pyrroloquinoline quinone (PQQ) complex outside a protein environment
- Acta Crystallographica Section C
Pyrroloquinoline quinone (PQQ) is an important cofactor of calcium‐ and lanthanide‐dependent alcohol dehydrogenases, and has been known for over 30 years. Crystal structures of Ca–MDH enzymes (MDH is methanol dehydrogenase) ...
Die Bedeutung der Stoff-Konstanten natürlicher Gesteine für Bauwesen, Geologie und Bergbau
- Fortschritte der Mineralogie, Kristallographie und Petrographie
Unter Heranziehen eigener Forschungsergebnisse und zahlreicher Einzelarbeiten aus den Gebieten Bauwesen, Geologie und Bergbau, wird auseinandergesetzt, wie sich aus der einfachen Werkstoffprüfung an Naturstein eine ...
Serpentinization-driven H2 production from continental break-up to mid-ocean ridge spreading: unexpected high rates at the West Iberia margin
Molecular hydrogen (H2) released during serpentinization of mantle rocks is one of the main fuels for chemosynthetic life. Processes of H2 production at slow-spreading mid-ocean ridges (MORs) have received much attention ...
Fluid–rock interactions in the shallow Mariana forearc: carbon cycling and redox conditions
Few data exist that provide insight into pro- cesses affecting the long-term carbon cycle at shallow fore- arc depths. To better understand the mobilization of C in sediments and crust of the subducting slab, we investigated ...
Past penguin colony responses to explosive volcanism on the Antarctic Peninsula
Changes in penguin populations on the Antarctic Peninsula have been linked to several environmental factors, but the potentially devastating impact of volcanic activity has not been considered. Here we use detailed ...
Ultramafic Carbonated Melt‐ and Auto‐Metasomatism in Mantle Eclogites: Compositional Effects and Geophysical Consequences
- Geochemistry, Geophysics, Geosystems
The mineralogy, chemical composition, and physical properties of cratonic mantle eclogites with oceanic crustal protoliths can be modified by secondary processes involving interaction with fluids and melts, generated in ...
