The G and D doublet, an intrinsic Raman feature of multi-walled nanotubes (MWNTs), was monitored in an ex-situ fashion for all intermediate stages of a manufacturing process of a MWNT/polymer nanocomposite. The G peak position and D/G ratios were monitored to characterize the changes in ...
In-situ monitoring of structural changes of spinel LiM^Oii electrode by using Raman spectroscopy was also done. It was found that 592cm'1 which corresponded to to A|B mode in -关键词: Raman speetroscopy Lithium-mangancse-oxides spinel materials Li-ion batteries ...
Surface-enhanced Raman spectroscopy has been used to probe pyridine, 4-ethylpyridine, and 4-cyanopyridine on silver and gold electrode surfaces. The difference between roughening the electrode in the absence (ex situ) or presence (in situ) of the analyte has been explored. Roughening in situ giv...
The formation of unwanted products is highlighted by an innovative method: in situ Raman analysis. During the annealing used to transform the almost amorphous as-deposited LiCoO2 into the rhombohedral structure useful for electrochemical cycling, the formation of Co3O4 has been observed. The second ...
Surface‐enhanced Raman scattering spectroscopy (SERS) was employed to investigate the molecular information of mitochondria from cancer cells (HepG2 and MCF‐7 cells) in situ with the assistant of mitochondrion‐targeting nanoprobes, which was compared with the isolation‐based ex situ method. The ...
