Abstract. Brucite Mg(OH) 2 belongs to a family of two-dimensional compounds with a CdI 2-type structure built up from layers of edge-sharing octahedra delineating 2D galleries.In the current study, nanometer-sized platelets of copper substituted Mg(OH) 2 were prepared by co-precipitation at room temperature in mixed alkaline (NaOH/Na 2 CO 3) medium.Very weak …
Enhanced weathering of (ultra)basic silicate rocks such as olivine-rich dunite has been proposed as a large-scale climate engineering approach. When implemented in coastal environments, olivine weathering is expected to increase seawater alkalinity, thus resulting in additional CO2 uptake from the atmosphere. However, the mechanisms of marine olivine weathering and its …
Asbestos fibres and human health. Chrysotile and amphibole asbestos have different chemical composition, resulting in different biopersistence and effects on health. Chrysotile is considerably less biopersistent and less potent for …
