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 spectroscopylithiumliquid ammonia1-iodododecane1594 cm -1The charge transfer induced lithiation of single-wall carbon nanotubes (SWNTs) was investigated by in situ monitoring by Raman spectroscopy as lithium was added incrementally to a dispersion of SWNTs in liquid ammonia. Charge transfer ...
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 ...
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 Raman cell An upgraded in situ Raman cell was used to collect the Raman spectra (Fig. 1). The new cell allows measurements with a reference electrode compared to a two electrode set-up, previously reported by us. Here we relied on lithium to act as both counter and reference [...

In this work, four nanostructured ceria-based catalysts (CeO2 nanocubes, 5% Cu doped CeO2, 5% Mn doped CeO2, 2.5% Cu and 2.5% Mn doped CeO2) prepared through hydrothermal synthesis31 were studied by in situ Raman spectroscopy at high temperature and during soot oxidation. Temperature-dependen...
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 ...
In Situ Raman Study of Phase Stability of alpha-Li3V2(PO4)(3) upon Thermal and Laser Heating Monoclinic α-Li3V2(PO4)3 has a complex 3-D metal phosphate framework that provides mobility for all three lithium ions, giving it the highest gravimetric ... N Membreño,P Xiao,KS Park,....
(observed visually) of reference compounds. The wires are typically made from platinum,iridium, orrheniumand enable in situ Raman measurements up to 3200K and beyond. More recently, aerodynamic levitation combined with laser heating has become a popular technique for melt studies (Hennet et al.,...
