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...
Raman spectra of as-made materials were measured by using HORIBA France, LABRAM HR Evolution. In situ Raman spectroscopy analysis was carried out on a confocal Raman spectrometer with a wavelength of 532 nm. Nitrogen temperature programmed desorption (N2-TPD) and carbon dioxide temperature ...
in situ analysismobile Raman spectroscopyRaman spectroscopy is considered as one of the most appreciated analytical techniques in the cultural heritage research field, thanks to some of its favourable characteristics such as the relatively quick time of analysis, identification of both inorganic and ...
Here, we use electrochemical, in situ Raman spectroscopic and computational techniques to investigate the interfacial water on atomically flat Pd single-crystal surfaces. Direct spectral evidence reveals that interfacial water consists of hydrogen-bonded and hydrated Na+ ion water. At hydrogen evolution ...

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 ...

Iin-situ Raman spectrometers enable scientists to measure reaction and process trends in real time, providing precise information about kinetics, polymorph transitions, and mechanisms.
In-situ HRTEM has also shown that fullerenes can be formed at the surface of a burning soot particle [68]. All these reports clearly show that there are many candidate structures for assigning to the ∼286.5 eV, ∼288 eV, and ∼290 eV peaks. However, because there seems to be a ...
