X-Ray Diffraction (XRD) measurements and results obtained for NPs show the existence of well-crystallized peaks and preferred phases. Re NPs have hexagonal structure while ReO3 NPs have the...

Thin films of rhenium trioxide (ReO3) were produced by reactive DC magnetron sputtering from metallic rhenium target followed by annealing in the air in the range of temperatures from 200 C to...

2020年1月22日 · ReO3-type structures can be described as ABX3 perovskites in which the A-cation site is unoccupied, giving rise to the general composition BX3, where B is typically a cation and X is a bridging...

The XRD peak of pristine ReO 3 has been characterized with the sharp peak corresponding to the planes observed in the composite material.

The structural evolution with alkali ion insertion, and the subsequent thermal evolution of the alkali-ion inserted ReO 3 electrodes are shown by employing in situ and ex situ synchrotron X-ray diffraction (XRD). During Na and K insertion, there is a combination of intercalation into ReO 3 and a two-phase reaction. Interestingly in the case of ...

2021年1月1日 · The excellent structural stability and high reversibility of NW- WNb 12 O 33 was confirmed by in-situ XRD results. NW- WNb 12 O 33 will become potential anode electrode for superior rate performance and long term stability.

2022年1月3日 · Information, Table S1. The XRD pattern of sample #1 (pure WO 3 thin film) corresponds to the monoclinic (P2 1 /n)WO 3 phase. Sample #2 has good crystallinity and is composed of a cubic (Pm3̅m ) ReO 3phase. A mixture of cubic ReO 3 and monoclinic (P2 1 /n)WO 3 phases with a reduced crystallite size 3 3 3 WO /WO). WO /

ReO 3 具有A位缺失的立方钙钛矿结构，在压力下会经历系列结构相变。 近期，通过高压低温电阻测试，发现其高压R-Ⅰ相（空间群为 R3¯¯¯ 3 ¯ c）具有高达 17 K的超导转变温度。 为探索新型Re氧化物超导体，采用ReO 3 为前驱体，在10 GPa和600 ℃的高压高温条件下制备了具有六方对称性（空间群为 P 6 3 22）的亚稳相，并在常压下对其晶体结构、磁性和电输运性质进行了表征。 实验发现，六方亚稳相的电阻在常压下250 K附近出现明显异常，温度低至2 K时仍未出现超导 …

2019年6月11日 · XRD is used to reveal the changes in crystal structure, chemical composition and state of ReO 3 /CFP samples. The peaks of CFP are marked with diamond rhombus (figures 2 (a) and S5). For the ReO 3 NS, two dominant diffraction peaks of (110) and (210) are located at 16.6° and 25.5° in both XRD patterns, which are consistent with hexagonal ...

2023年6月1日 · The crystallinity and purity of ReS 2 were examined by X-ray Diffraction (XRD) technique. XRD measurements were carried out in Bragg-Brentano geometry using D8 Advance diffractometer (Bruker AXS) equipped with LynxEye strip detector and …
