The results agree well with earlier static and dynamic measurements in the pressure range up to 0.2 TPa. An equation of state for the high-pressure phase of iron oxide was constructed and compared with data at high pressures and temperatures.Nikolaev, D. N....
to be recycled by fermentation andmethanogenesis. (Equation[26]is itself only approximate, as it does not include terms in the global redox budget that comes from burial of sulfur species (FeS2and CaSO4) or from oxidation of ferrous iron. These additional terms become important when trying to ...
Nevertheless, it is difficult to ascertain whether the soluble iron is directly attributed to the anthropogenic component, or has been enhanced by complex atmospheric processing70,71or climate change72. For example, a measurement of iron solubility of ice-core dust in the Last Glacial Maximum (26,...
The monomer (i.e. OEGA) conversion was calculated by the following equation, where I5.9 ppm and I4.2 ppm correspond to the integral of the vinyl signal from the monomer at 5.9 ppm (1H mol−1) and the ester signal from the monomer/polymer at 4.2 ppm (2H mol−1), ...
Iron oxide solubilization by organic matter and its effect on iron availability The solubility of Fe in soils is largely controlled by Fe oxides; ferrihydrite, amorphous ferric hydroxide, and soil-Fe are generally believed to exert the... WL Lindsay - 《Plant & Soil》 被引量: 200发表: 1991...
The reason is that the molar mass of the substance affects the conversion. This site explains how to find molar mass.Formula weights are especially useful in determining the relative weights of reagents and products in a chemical reaction. These relative weights computed from the chemical equation ...
The purpose of this study was to undertake a computational modeling analysis of the deposition kinetics of a magnetite nanoparticle agglomerate in cell culture medium. Methods: Finite difference methods and the Crank-Nicolson algorithm were used to solve the equation of mass transport in order to ...
sorption capacity decreased as the same when iron oxides was removed.Compared to one-site model based on first order kinetic equation,two-site model was more pertain to fit the adsorption dynamics of Cd2+ on the paddy soils.Quick adsorption rate constant of HN paddy soils decreased,while it ...
but to significantly different degrees. We attribute this result to a slight lattice distortion ofhcp-Fe after substituting Fe with other atoms. Lattice distortion could reduce the shear modulus of the alloys (Fig.S7), which further reducesVSaccording to equation 4. Thus, owing to this effect,...
The technique involves the use of a metal oxide as an oxygen carrier that transfers oxygen from the combustion air to the fuel. The use of iron oxide as an oxygen carrier has been investigated. Particles composed of 4080 wt % Fe2O3, together with Al2O3, ZrO2, TiO2, or MgAl2O4, ...
