2023年5月15日 · Specifically, the hcp-CoNi-N/C-700 displays an irregular nanotubular structure (Fig. S5 g–i), and the XRD pattern in Fig. S6 exhibits the characteristic diffraction peaks of common fcc phase Ni instead of hcp phase Ni.

In this paper, we present a simple and controllable preparation of face centered cubic (fcc) and hexagonal close-packed (hcp) Ni nanoparticles by a pulsed Nd:YAG laser ablation method in the...

摘要 采用溶胶-凝胶法和热处理技术，用柠檬酸盐合成了面心立方（fcc）和六方密堆积（hcp）Ni纳米颗粒。 使用X射线衍射（XRD）、透射电子显微镜（TEM）和振动样品磁强计（VSM）对样品的结构、形貌和磁性进行表征。

XRD pattern of nickel nanoparticles in Figure 2 demonstrates that the nickel nanoparticles have full face- centered cubic structure (fcc). Three peaks at 2θ, 45˚, 52.3˚, and 77.4˚in4˚in ...

The as prepared nanocomposite is characterized for their structure, size, morphology and constitution by X-ray diffraction (XRD), diffuse reflectance spectra (DRS), Transmission electron ...

2008年6月12日 · The structure, morphology and magnetic properties of the samples were characterized using X-ray diffraction (XRD), transmission electron microscopy (TEM), and vibrating sample magnetometer (VSM). Our XRD and TEM results suggested that hcp Ni nanoparticles were successfully synthesized when the heating temperature reaches 300 °C.

2024年10月1日 · Recalculated orientation distribution functions (ODF) sections (determined by XRD) of the Ni 1.5 CrFeCu 0.5 HEA rolled in different thickness reductions alongside the schematic of the location of the texture components of FCC materials.

2017年2月21日 · The peaks of the XRD pattern for nano Ni corresponded to the fcc Ni structure (Fig. 3). The pattern of the Ni-Sn nanoparticles with an initial ratio Ni:Sn = 3:4 could be readily indexed to a low-temperature Ni 3 Sn 2-type orthorhombic structure, namely, the Ni 2.7 Sn 2 …

The stacking fault energies of the fee alloy series Fe-28 Ni to pure Ni were investigated using X-ray diffraction line profile analysis. A minimum stacking fault energy of about 70 mJ/m 2 occurs at the approximate composition of Fe-40 pct Ni.

In the present work, we report the synthesis of hcp and fcc Ni and Ni/NiO nanoparticles using a citric acid assisted Pechini-type method. We show that this method allows precise control of the structure of the nanoparticles through some easily adjustable processing parameters.
