Raman and Wide Angle X-Ray Scattering data demonstrated a strong interaction between the matrix and the nanofiller. Electron Paramagnetic Resonance spectra of these nanocomposites reflect strong anisotropic electron interactions among the nanofiller's electrons....
Figure S1. The Raman spectra of the spent Na-ZnFe@C catalyst with operation time of 60 h and 120 h. Note: The origin of the slight loss in CO2 conversion and gradual increase of CO selectivity was investigated. The structural evolution behaviors of the carbon layer during the long-term ...
Raman spectra were performed on Via-Reflex via Raman spectroscopy. XPS analyzes using ESCALAB 250Xi. The electrical conductivity measurement was determined using a Hall measurement system (Lakeshore 8400 Series HMS, USA). 2.5. Electromagnetic measurement The electromagnetic parameters measurement of EM ...
Raman Spectroscopy: Raman spectroscopy was conducted on an In Via Qontor confocal micro-Raman spectrometer (Renishaw, UK) to characterize the graphitic degree of carbon materials. In situ Raman: In situ Raman spectra was obtained using a self-made cell, the schematic diagram of the in situ cell...
Then, the Fe3O4 nanoparticles and Fe3O4@SiO2 composite nanoparticles were characterized by means of X-ray diffraction (XRD), Raman spectra, scanning electron microscope (SEM) and vibrating sample magnetometer (VSM). Recently, the studies focus on how to improve the dispersion of composite ...
摘要:采用弱磁场辅助氧化共沉淀法制备不同形貌的纳米Fe3O4颗粒,并将改性后的颗粒分散添加到#40机油中进行金属摩擦副的磨损试验,采用扫描电子显微镜、X射线光电子能谱和Raman光谱观察和分析摩擦副钢的磨痕表面形貌和化学组成。结果表明:Fe3O4纳米颗粒被粘附在摩擦副钢表面,填补了摩擦表面的缺陷区域,对磨损表面起...
(Supplementary Fig.8a), Raman (Supplementary Fig.8b) and XPS (Supplementary Fig.12) spectra of B-Fe3O4-C were similar to those of SP-Fe3O4-C. The ferric oxide content of B-Fe3O4-C was 21.0 wt% based on TGA (Supplementary Fig.8c), which was close to that of SP-Fe3O4...
Raman spectra for the as-synthesized N-S-G/Fe3O4composite. Full size image The morphologies of the as-prepared graphene, N-S-G/Fe3O4composite, as well as the pure Fe3O4, have been respectively investigated by the scanning electron microscope (SEM), the field-emission scanning electron ...
