1)打开白光; 2)点击摄像机; 3)调节粗焦向下移动至光斑聚集成点(若载玻片位置与镜头偏移过大,利用操作杆前后左右移动来调整,调整后再移动粗焦); 4)关闭室内灯光; 5)眼睛注视电脑,继续缓慢移动粗焦(一定要慢,防止镜头与载玻片相撞),当出现第一个清晰画面时,左右移动操作杆,观察画面是否移动,若不动,则可判断...

Iin-situ Raman spectrometers enable scientists to measure reaction and process trends in real time, providing precise information about kinetics, polymorph transitions, and mechanisms.
摘要: We demonstrate an application of Raman spectroscopy for in-situ measurements of gas and liquid phase catalytic reactions. After a hybrid fitting and integrating processing, the Raman spectra provide quantitative information of the near-surface region....
Raman spectroscopy has been used to carry out in situ studies of K3PMo12O40 state in acrolein oxidation. It has been established that at 400°C the simultaneous effects of both the reaction mixture and laser beam lead to the formation of surface MoO3 on the catalyst. This is a preview ...
Topological insulators (TIs) are a new state of quantum matter with a band gap in bulk and conducting surface states. In this work, the Raman spectra of topological insulator Bi2Te3 films prepared by molecular beam epitaxy (MBE) have been measured by an in situ ultrahigh vacuum (UHV)-MBE...

The Raman wavenumber of the symmetric stretching vibration of carbonate ion (ν1-CO32−) was measured in three aqueous solutions containing 2.0 mol·L−1 Na2CO3 and 0.20, 0.42, or 0.92 mol·L−1 NaCl, respectively, from 122 to 1538 MPa at
Raman spectroscopy has proven to be a unique analytical tool for studying electrode materials of lithium-ion batteries due to its ability to probe structural changes at the level of chemical bonds. In this work, the calculated Raman spectrum of α-Li3V2(PO4)3 provided by density functional th...
In addition Raman ex situ spectra of as-prepared film was obtained. The increase in the irradiation time of the sample was enough to alter the nature of the constituent species of the oxidized film, preferably favoring the aromatic chains, together with the dication segments. Photoluminescence ...
