5a. The γ-Al2O3 is the dominant oxide phase under equilibrium conditions, which is a spinel structure with cation vacancies10. Figure 5b shows that the electrochemical corrosion process results in a reduction in the mole fraction of the alloy matrix. Potential-pH diagrams in Fig. 5c, d ...
This article selects the wearability strong NiFe2O4 spinel to take the ceramic substrate, for enhances the NiFe2O4 spinel toughness and the electrical conductivity, uses with the metal Ag compound way, simultaneously, for improves the ceramics and the metallographic phase moist union, the attempt in...

Recent conflicting results on the mechanism of the olivine-spinel phase transition suggest that the mechanism varies with experimental conditions. Evidence for a shear-induced mechanism is strong in experiments performed at temperatures far from the melting point or under conditions where very large ...
Describing the microscopic behavior of strongly correlated electronic systems in transition-metal oxides with geometrically frustrated lattice structures is a fundamental challenge1,2. Strong correlations coexist with magnetic frustration, orbital degeneracy, and charge-ordering effects often lead to novel ...
Magnetite (or lodestone) is a common accessory mineral in coarse-grained igneous rocks and metamorphic rocks. It may be gray-black or have a rusty coating. Crystals are common, with striated faces shaped like octahedrons or dodecahedrons. Look for a black streak and a strong attraction to a ...
Together with this, a strong band assigned to the C=O group of non-coordinated or weakly coordinated oleic acid can also be observed, which is more intense in the case of FeOL_A and FeOL_E (Fig. 1). This last sample also presented a stoichiometric relation of oleate ligand with respect...
If the Anderson weak localization mechanism is the sole cause for the insulator nature, one expects the negative magnetoresistance phenomena for all Bi2A2Co2O8 compounds. This is, however, not the case16. Also the suppression of the specific-heat peak and Seebeck coefficient under strong magnetic...
