The ethanol-suspended NWs were pipetted onto a clean glass microscope slide and allowed to air-dry. Thereafter they were analyzed using a Horiba LabRAM HR Raman spectrometer with an Olympus BX41 microscope attachment. A low laser power of 0.4 mW was used so that the magnetite would not be converted to hematite, as shown by Faria et al. [25 (link)]. The 514.5 nm laser wavelength used was from a Lexel Model 95-SHG argon ion laser.

The microcrystalline carbon structure, such as the degree of ordering and graphitisation of carbon in the coal and composites was characterised using Raman spectroscopy. Raman spectra were obtained for fine samples of the coal and composites using the excitation laser wavelength 514.5 nm (nm) line of the Lexel Model-95 SHG argon-ion laser. The instrument is integrated into a Horiba LabRAM HR Raman spectrometer fitted with an Olympus BX41 microscope and the data were acquired using LabSpec v.5 software.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
