The MoS2films used in this work were prepared by polymer-assisted deposition (PAD) similar to our previous work23(see details in Methods and Supplementary Fig.1). The Raman spectrum collected from the strained film shows that the in-plane vibrational mode\({E}_{2{{\mbox{g}}}^{1}\)of ...
酸蚀导致CG的SSA显著提高,CG950的最高值为1002.6 m2/g(图1c),为O2的吸附和活化提供了潜在反应位点。Raman结果(图1d)表明CGS的ID/IG值随着热解温度的升高而增加,在950℃时达到1.20。EPR结果(图1e)表明CG950比生物炭的强度高很多,...
Stimulated Raman spectra (SRS) of H2O, D2O, H2O–D2O mixtures, and aqueous solutions of NaClO4have been measured using a mode‐locked, stabilized Nd glass laser operating in the TEM00mode. Spectra with relatively narrow peaks were obtained in all cases, as predicted by the first order theory...

Ramanayaka et al. (2020a) pointed out that no physical adsorption was found in the adsorption of Cr(VI) by nanobiochar, and the surface –OH, –COOH, –C=O and other oxygen-containing functional groups provide electrons for the reduction of Cr(VI), which was confirmed by Zhang et al....
XPS和Raman光谱显示,N-PC1000拥有最低的N元素含量(2.0 at.%)和最高的Raman光谱ID/IG值(1.01),P, N-PC和S, N-PC上P和S元素的掺杂量分别为3.7 at.%和0.3 at.%。此外,不同样品的含氧官能团组分也存在较大的差异,这说明杂原子掺入能够显著影响碳层表面缺陷位点和含氧官能团结构。催化研究发现,N-PC1000...
The influence of water vapor on the growth of SWCNTs was investigated by characterizing the morphology and structure of the carbon products using scanning electron microscopy, X-ray diffraction, transmission electron microscopy, and Raman spectroscopy. Results show that SWCNTs with a high purity were...

Observations of water monomers in supersaturated NaClO4, LiClO4, and Mg(ClO4)(2) droplets using Raman spectroscopy Taking advantage of the structure breaking effect of ClO4- on the hydrogen bonding network of water molecules, Raman spectra of water monomers in these ... ‡A Yunhong Zhang†,...
The Raman lidar technique is arefinement of the lidar method and permits, besides the measurement of particle optical properties, the simultaneous profiling of the water-vapor mixing ratio and temperature with high range resolution and accuracy. This technique does not require alaser transmitter with ...
