Sentence examples for by the spinel diffraction from inspiring English sources

For the aerogel AG-20NiAl oxide sample, the Bragg diffraction peaks at 19°, 37°, 45°, 60° and 65° can be well defined as (111), (311), (400), (511) and (440) crystal faces of the cubic phase NiAl2O4 spinel, with space group of Fd3m (JCPDS: 10 0339), while the diffraction peaks of γ-Al2O3 support are very broad or masked by the spinel diffraction peaks [16].

In all cases, the detected electron nano-diffraction patterns of the as-prepared samples can be described by the spinel phase of Co3O4 [39].

In fact, all reflections of the nano-diffraction patterns in Fig. 6 can be reproduced by simulating the kinematic electron diffraction patterns of the spinel structure in [211], [531], and [321] zone axis orientations.

X-ray diffraction measurements confirmed the spinel structure and average size of uncoated maghemite nanoparticles to be around 20 nm in diameter.

As demonstrated by X-ray diffraction, Fe3O4 nanoparticles are of the spinel type and magnetic Fe3O4 [ 17, 20] can absorb a considerable amount of energy and transform this energy into heat when exposed to AMF.

This high dispersion can be explained by an inhomogeneous distribution of the ions in the spinel and also by a rough surface of the sample.

XRD of the sintered NCs is provided in Fig. 2. The diffraction peaks correspond to the spinel phase of iron oxide, which can include γ-Fe2O3 or Fe3O4.

by invoking a model for the spinel solid solution.

All XRD diffractions show the typical peaks of the spinel structure, such as (220), (311), and (400), without any other unexpected peaks from by-products like MnO, ZnO, or other metal oxide forms.

The oxidation of oxalic acid by photoholes prevents the corrosion of the spinel.

The results indicate that the structure of the ternary spinel remains when some of the O2− in the spinel phase are replaced by Br−.
