The XRD pattern of NiO showed three major diffraction peaks and was indexed as (111), (200) and (220) crystal planes with a cubic structure which is in good agreement with literature value (JCPDS...

As a p-type metal oxide, nickel oxide (NiO) has been extensively utilized for providing a favorable hole transport pathway in organic solar cells (OSCs). To obtain higher crystallinity, a...

2024年5月1日 · X-ray diffraction (DRX) was used to characterize the produced films. The study shows that all of the films (NiO) crystallized in the face-centered cubic phase (CFC), with an estimated lattice value of 4.17 Å. The film is oriented according to the plane (1 1 1) and (2 0 0).

2013年12月1日 · Nickel oxide (NiO) nanoparticles were successfully synthesized by the reaction of nickel chloride with hydrazine at room temperature and thermal decomposition of the precursor nickel hydroxide (Ni(OH) 2) nanoparticles. The products were characterized by X-ray diffraction, Transmission electron microscopy, Fourier transform infrared spectroscopy ...

Hydrogen reduction of porous bulk NiO particles has been studied with in situ hot-stage X-ray diffraction (XRD) in the temperature range 175–300 °C. This technique has the ability to measure...

They report the NiO DRX patterns of the Millers index of (111), (200), (220), (311) and (222). Fig. S2b) shows the XPS spectra of NiO with the characteristic patterns for C, Ni, and O. The results coincide with the reported by Yun-Guang et al, and Soleimampour et al. for NiO. Fig. S1 SEM images of NiO without ozonation A) 20000x, B) 100000x.

2022年10月31日 · 近几年来，阳离子无序岩盐正极（cation-disordered rock-salt cathodes, DRXs）凭借其高容量、低成本和可设计性有望成为新一代锂离子电池的正极替代材料。 这类材料主要由富锂的过渡金属氧化物或氟氧化物构成。 从统计的角度来看，在它的立方密堆积结构中，锂离子和过渡金属阳离子均随机占据八面体位点。 然而，在更小尺度的局部环境中，关于这些阳离子的排布情况的系统研究，尤其是实验研究目前非常有限。 这与当前采取的晶体衍射技术有关 …

2024年1月1日 · This study aims to investigate the distinctive characteristics of a specialized dynamic recrystallization (DRX) process, which results in a fine and uniform distribution of β grains within the single phase region of as-cast Ti644321 alloy. The formation of deformation bands (DB) and flow localization (FL) is a result of the instability region.

L’analyse élémentaire de l’oxygène montre que nous retrouvons les formes oxydées NiO et Fe 2 O 3 comme indiqué en DRX, où l’oxyde de nickel est mélangé à l’oxyde de fer. En résumé, nous pouvons avancer l’hypothèse de la formation d’un alliage …
