The results show that: the crystal structures of the film samples prepared by heat-treating the nickel oxide films and sulfur at 400–600 °C are nickel disulfide (NiS2) with the pyrite structure, the average value of the cell constant a is 5.69 Å calculated from the XRD peaks ...

The XRD pattern of the as-prepared Ni(OH)2 precursor is shown in Fig. 1a. All the reflectance peaks can be perfectly indexed to those of a pure phase of Ni(OH)2 with a hexagonal structure. The XRD pattern of the synthesized nickel oxide flower-like structure in Fig. 1b shows ...
This research presents a novel biological route for the biosynthesis of nickel oxide nanoparticles (NiO NPs) using marine macroalgae extract as a reducing and coating agent under optimized synthesis conditions. XRD and TEM analyses revealed that phytosynthesized NiO NPs are crystalline in nature with ...
oxide nanocomposite sample may contain hematite, which was not detected in the XRD analysis (Fig.1), possibly because it has an amorphous phase or a very weak intensity. Raw zeolite has zero saturation magnetization, indicating it remains unmagnetized in external magnetic fields. This is typical ...
XRD scan: a film peak at 47.4° and a broad peak at ~26°. These features are reminiscent of disordered and non-stoichiometricRNiO37,60,61. However, the stoichiometric film exhibits none of the 00lsuperlattice peaks expected for bulk Nd4Ni3O10. The neodymium-rich film, on the other hand...

For elements in HTL, three binding energy ranges were selected: 850–868 eV for Ni 2p3/2, 441–455 eV for In 3d3/2 and In 3d5/2 doublets (both metals in the oxide form), and 525–535 eV for the O 1 s composition. Fig. 1a and 1d show the Ni 2p3/2 peaks corresponding to ...
Using solgel and coprecipitation methods, we synthesized cobalt-free, nickel-rich NMA and characterized its crystalline phases through XRD, SEM, Raman, FTIR, ICP, and BET techniques. XRD showed that coprecipitation achieved higher crystallinity with well-defined peaks. SEM revealed that co...
