Pyrite is the earth's most abundant sulfide mineral. Its frequent undesirable association with
minerals of economic value such as sphalerite, chalcopyrite and galena, and precious …

Catalytic solids in the spotlight: Detailed insight into the working principles of heterogeneous
catalysts is essential for the design of improved or totally new ones. Such insight can be …

The association of organic matter (OM) with minerals is recognized as the most important
stabilization mechanism for soil organic matter. This study compared the properties of Fe …

Hydrocarbon generation reactions occur within organic-rich shales as a response to thermal
maturation. Here, we report observations on samples from the organic-rich Mississippian …

Hydrocarbon generation and retention processes occurring within gas shales as a response
to increases in thermal maturation are still poorly constrained. While efforts have been …

Phosphorus availability in soils is an important parameter influencing primary production in
terrestrial ecosystems. Phosphorus limitation exists in many soils since a high proportion of …

The catalytic hydrogenation of aromatic nitro compounds containing multiple functional
groups into amino compounds with high conversion rates, selectivity, and stability under …

Minerals formed by bio-oxidation of ferrous iron (Fe (II)) at neutral pH, their association with
bacterial ultrastructures as well as their impact on the metabolism of iron-oxidizing bacteria …

An amorphous or nanocrystalline calcium carbonate (ACC) phase with aragonite-like short-
range order was found to be a transient precursor phase of calcite precipitation mediated by …

Scientific imaging represents an important and accepted research tool for the analysis and
understanding of complex natural systems. Apart from traditional microscopic techniques …
