The Effects of Biochar and Reactive Iron Additions on Soil Carbon and Nitrogen Retention
… microorganisms and eventually is lost to the environment as greenhouse gases and non-point source pollution. Many soils lack the physical and/or chemical properties that enable some human-modified soils (e.g., terra preta soils in the Amazon Basin) to stabilize and retain C and nutrients in SOM …

Quantity and isotopic composition of reduced sulfur in Cretaceous organic-rich shales
… However, existing models of sulfur-carbon-iron relationships cannot account for the distribution of pyrite in mid-Cretaceous shales. Pyrite distribution in these sediments can better be described in terms of: (1) the quality of organic matter available and its effect on reduction rate, (2) …

Selective Oxidations by Iron(III) Porphyrins and Iron(III) Corroles
… macrocyclic ligands and the corresponding iron(III) complexes which are fully characterized by UV-vis, GC/MS, and NMR spectroscopies. In this work, the potential of catalytic oxidation reactions towards organic sulfides by these metal complexes were studied. The iron(III) porphyrin and …

Effect of base metal oxygen content and oxygen activity on mechanical properties of EN-GJL- GG - 26 Cu-Cr grey cast-iron heavy-duty crank cases
Grey cast iron is a type of cast iron named for its grey appearance due to the presence of graphite flakes in the material. It is widely used in engine components, because of its wide range of mechanical and physical properties, which include strong heat conductivity, vibration damping …

Stability of micronutrients in nutrigems during cooking and accelerated storage
… to deliver vitamin A (VA, as retinol palmitate), iron and the combination. Two types of iron sources were evaluated: sodium iron (III) ethylenediaminetetraacetate (FEDTA) and ferrous sulfate (FS). Nutrigems and rice were mixed (1:100 w/w) and cooked in a conventional rice cooker. Samples were …

Extracellular Electron Shuttle Mediated Biodegradation of Hexahydro-1,3,5-trinitro-1,3,5-triazine
… compounds to mediate electron transfer between iron (hydr)oxides and Fe(III)-reducing microorganisms was investigated for decontaminating RDX. The ultimate goal of this study is to develop an optimal strategy for the biodegradation of nitramine explosive compounds. This study demonstrated that …

Dynamics of soil processes under extreme meteorological boundary conditions - response of below-ground carbon, sulfur, and iron cycling in fen soils
… however, investigated changes in average environmental conditions in the long term, while the impact of extreme weather on peatland elemental cycles is still uncertain. Moreover, most studies do not provide a mechanistic understanding of the redox processes underlying the response of …

The production of pure hydrogen with simultaneous capture of carbon dioxide
… necessary for the future. For hydrogen, an environmentally-benign energy vector whose sole combustion product is water, to become a major energy source, it must be produced in an efficient, CO2-neutral manner. A process, which uses a packed bed of iron and its oxides, viz. Fe, Fe0:947O, Fe3O4 …
