The Raman spectra were measured by a 532 nm wavelength excitation, using a laser power of D2 filter and one acquisition cycle for 120 s to avoid film damage. Mechanical and tribological properties characterizations. The mechanical and nano-tribological properties of deposited films were ...
通过HRTEM、XRD、Raman、XPS测试(图2f和图3a-e)进一步证明了材料的物相组成。纳米片阵列相互连接、纵横交错,形成具有大量空隙的3D网络结构,有利于Na+和电解质的转移、渗透,有效缓解体积膨胀。CMSe纳米片阵列可以极大地增加反应位点,促进电极和电解质之间的电化学反应。此外,碳的存在不仅提高了材料的导电性,还缓解了电...
Resonance Raman spectra have been obtained for C. pasteurianum ferredoxin, Chromatium HiPIP and Fe 4S 4(SCH 2Ph) 4 2−*, all of which contain a cubane-li... SP Tang,TG Spiro,C Antanaitis,... - 《Biochem Biophys Res Commun》 被引量: 32发表: 1975年 Synthesis and characterization...
In addition to the high-resolution transmission electron microscopy methods, the presence of carbon on the surface of particles was also confirmed by Raman spectroscopy. The use of these analysis techniques in combination with the results of derivatography and thermogravimetry made it possible to ...
Raman spectra were performed by using a Witec/alpha 300R confocal microscope with a 532-nm laser at atmospheric conditions. The XPS was performed using a PHI 5000 X-ray photoelectron spectrometer equipped with a monochromatic using Al Kα radiation (hν=1486.6 eV), and the peaks were ...
The absence of MoOx Raman signal at 500 °C might be caused by the thermal emission that masked the weak vibrational information or the presence of laser that enhanced the reduction of surface oxygen atoms34. After that, the MoO3 signal was reproduced when the sample was exposed to ...
All compounds were characterized by X-ray structure analysis. IR, Raman, electronic, and 77Se NMR spectra are also reported. Thermal decomposition of 1−3 was studied by thermogravimetry. 展开 DOI: 10.1021/ic0488637 被引量: 27 年份: 2005 ...
