Carbon

Carbon nanotube (CNT) and graphene are the most popular materials being studied currently since they carry on so many significant features which are unbelievable to normal materials. By re-designing and decorating the micro-structure, they demonstrate an even greater flexibility to meet human needs. Raman technology is a good tool to collect RBM spectra in CNT and G-band/ D-band in graphene due to the fact that the small Raman peak shift is proof right from the slightly different structure, making it an ideal instrument to characterize the material structure in carbon science.

Application Notes

Carbon black is a form of amorphous carbon. It is mainly used as reinforcement filler in automobile tires and other rubber products, but is also used in pigments, paint, and carbon paper. Raman spectroscopy is a very effective analytical technology to characterize carbon materials. The fast characterization of carbon black material using Raman spectroscopy is discussed here to demonstrate that Raman technology is well suited for carbon black material characterization.

Various different allotropes of carbon such as graphite, diamond and amorphous carbon can be analyzed using Raman spectroscopy. Even more advanced allotropes such as carbon nanotubes (carbon with a cylindrical nanostructure) and graphene (crystalline with 2 dimensional properties) can be effectively analyzed using Raman spectroscopy.

Quality control in the food industry is a key issue that requires rapid, efficient and selective methods that could discriminate the products, detect fraudulent or accidental adulterations, and identify the content of some biomarkers within a particular process of storage conditions. For this, Raman spectroscopy in conjunction with the optical properties of metallic nanostructures is a powerful technique that can be implemented in food analysis.
