An important distinction in Fe exploration is to determine in which mineral phases the Fe is hosted, rather than just the total Fe content. Significant portions of the total Fe in a magnetite deposit can be hosted in hematite or pyrrhotite, and of course silicate minerals.

The two competing hypotheses for calc-alkaline differentiation—magnetite versus garnet (± amphibole) fractionation—predict contrasting Fe isotopic fractionation pathways in evolved melts because magnetite preferentially depletes ferric, isotopically heavy Fe whereas garnet (± amphibole) does the opposite.

Fe-based metallic glasses have garnered significant attention due to their low coercivity force and core loss. Enhancing the saturation magnetic flux density (Bs) of Fe-based metallic glasses is crucial for their industry applications. This work constructed a dataset comprising 330 training data and 157 test data. The support vector regression …

In this work, the relationship of atomically interfacial Fe and adjacent Ni activity in Fe-doped Ni(OH) 2 with Fe/Ni atomic interfaces is elucidated in detail via theoretical calculations. In this experiment, we innovatively made Fe aggregate locally to design a Ni/Fe atomic interface in a Fe-doped Ni(OH) 2 single-phase crystal structure.

Objective: Learn what an FE Model is and how to create one. What is an FE Model? An FE model brings together all of the necessary elements for the part to be analyzed, whether in simulation, optimization, or further analysis. An FE model is built up of Components and Connectors.Each component contains an FE Mesh and Attributes, while connectors are …

Ni–Fe (oxy)hydroxide and Co–Fe (oxy)hydroxide are among the most active oxygen evolution reaction (OER) catalysts in alkaline media. Fe is essential for the high activity, but the details of how Fe is incorporated into the Ni or Co (oxy)hydroxide structure and affects catalysis remain incompletely understood.
