The high-iron composition and density of a hypothesized, early-formed enriched mantle reservoir is compatible with seismic observations indicating large, low-shear velocity provinces (LLSVPs) (e.g., Trampert et al., 2004) present in the mantle today.
In this study, the results from extended demonstrations conducted using two reactor configurations and two oxygen carrier types differing in size and iron composition are presented.
The community in the Red sample has a much higher species richness than the Black sample, and the differences between the Soudan and Iron mines reflect the iron composition (hematite versus pyrite), temperature, and pH of the various environments[ 7].
Significant variation of the resulting attenuation lengths indicated the importance of problem-dependent multigroup cross sections and proper modeling of iron composition in deep-penetration calculations.
For the ECAP processing, round billets of Armco iron (composition in Table 1) with a diameter of 20 mm and a length of 100 mm were machined from rods with a diameter of 30 mm.
Along with the increase of the molar ratio of iron chloride to that of ruthenium chloride, the level of iron composition in the bimetallic nanoparticles tended to increase.
Concerning the iron composition, the increased of the iron loading yielded to Fe2O3/SiO2 materials with iron species less susceptible to be leached-out.
However, on the other hand, the level of iron composition in the generated bimetallic nanoparticles remained one third that of ruthenium (43.65:14.63, at.%) in the case of the condition of molar ratio of 1 2 between RuCl3 and FeCl2 despite the doubled amount of iron precursor in the reactant solution.
In case (a, 1 9) the content of iron precursor is richer than that of ruthenium precursor in the reactant solution, the synthesis of bimetallic Fe-Ru oxide particles of which the level of iron composition is higher than that of ruthenium can be identified from the yellow dots representing an iron.
Two neutron energy group structures, three degrees of self-shielding correction, and two iron compositions were considered in this study.
Higher iron compositions of nanoparticles require irradiations of higher laser pulse energies typically more than 350 mJ, which is considered to be due to the difficulty in dissociation of Fe(III) acetylacetonate compared with Pt II) acetylacetonate.
