The chemistry textbooks tell us that uranium was discovered by the German chemist, Martin Heinrich Klaproth, in 1789, which is perhaps a simplification of the truth. The element was named after the planet Uranus and what Klaproth reported to the Royal Prussian Academy of Science in that year was uranium oxide, which he had separated from the heavy, black mineral known as pitchblende. The elemen...

Abstract While the role of mineral weathering (MWe) bacteria in nutrient cycling and plant growth promotion is established, our understanding molecular mechanisms involved how their contribution to MWe varies according properties environmental conditions remain poorly documented. In this study, we investigate type mineral, source carbon buffering capacity medium impacted effectiveness at strain...

This computational study performed using the density functional theory shows that hydrated and non-hydrated tetrahedral and octahedral kaolinite mineral surfaces in the presence of a cation adsorb the nucleic acid bases thymine and uracil well. Differences in the structure and chemistry of specific clay mineral surfaces led to a variety of DNA bases adsorption mechanisms. The energetically most...

This discussion paper is/has been under review for the journal Atmospheric Chemistry and Physics (ACP). Please refer to the corresponding final paper in ACP if available. Abstract The aim of this study is to determine the mass deposition flux of mineral dust to the tropical northeast Atlantic Ocean at the Cape Verde Atmospheric Observatory (CVAO) on the island Sao Vicente for January 2009.
