To clarify the inconsistency between calculated and existing experimental X-ray diffraction (XRD) pattern for dicopper magnesium (MgCu2) nd to identify the impurity phase in Cu-sheathed MgB2 superconductors, polycrystalline MgCu2 samples were synthesized and studied by XRD easurement. The XRD result shows that the (2 2 0), (4 2 2), (6 2 0), and (6 4 2) reflection lines, which are missing from t...
Continuous hydrothermal synthesis of metal oxide nanoand microparticles in supercritical water was performed in a continuous flow reactor. The results of investigation of LiCoO2, LiNiO2, LiZnO2, LiCuO2, Ga2O3, CeO2 nanoparticles by HRTEM and XRD analysis were presented.
Cellulose-silica composite fiber samples have been successfully synthesized using cellulose solution, tetraethoxysilane, and NH3•H2O in ethanol/water mixed solvents at room temperature for 24 h. The cellulose solution was previously prepared by the dissolution of microcrystalline cellulose in a solvent mixture of N,N-dimethylacetamide (DMAc)/lithium chloride (LiCl). The effect of the tetraethox...
Introduction: The Mars Science Laboratory (MSL) rover Curiosity recently completed its fourth drill sampling of sediments on Mars. The Confidence Hills (CH) sample was drilled from a rock located in the Pahrump Hills region at the base of Mt. Sharp in Gale Crater. The CheMin X-ray diffractometer completed five nights of analysis on the sample, more than previously executed for a drill sample, a...
Divalent complexes of iron and cobalt with new, monoanionic tripodal amido-polyphosphine ligands have been thoroughly characterized, and XRD analysis reveals geometries that are distinct for this class of ligand.
X-ray diffraction (XRD) can provide useful information about the composition of an ore sample in terms of quantification of crystalline phases and also amorphous content. XRD is also a powerful technique for studying substitutional solid solutions that can affect mining productivity, such as determining lattice bound aluminum in Goethite. Knowledge of the phases present can predict processing r...
