Web31 aug. 2016 · Mineral Surface Science and molecular Geochemistry have contributed to the establishment of Nanogeoscience with regard to the study of nanoparticles in nature and the investigation of geological processes in the nanoscale (1 nm–100 nm). As an example, a part of the research currently elaborated concerns the surface chemical behavior of calcite. WebMore recent studies indicate surface plant litter and soil are important sources of DOM in groundwater (Baker et al. 2000; Kalbitz et al. 2000). Surface precipitation drives the transport of DOM through the soil column to the saturated zone. During infiltration, selective interactions between DOM and soil minerals
