“…Characterization of amorphous carbon from camphor soot: Camphor exhibits highest CNT-production efficiency with minimal waste production. Moreover every atom of camphor plays a positive role in carbon nanotube synthesis, which accounts for maximum carbon-to-CNT conversion efficiency which is reported by many authors earlier 4 . Camphor, a botanical hydrocarbon, on burning undergoes hermal decomposition to give soot.…”

“…The intensity ratio for the two bands treated with acetone is observed to be 1.83. This value indicate that comparatively low percentage of carbon nanotubes are formed in the diesel soot and higher disorder in the sample 4 . The lateral size of the aromatic lamina (La) formed is found to be 11.7 nm where as stacking height (Lc) is found to be 8.1 nm for the diesel soot.…”

Hydrocarbons are by far the most widespread precursors among carbon sources employed in the production of carbon nanotubes and carbon nanosphers. In the present study, diesel and camphor have been used as precursors for nanomaterials. Carbonaceous soot produced from combustion of diesel in engine shows the presence of significant amount of carbon nanomaterials. The γ band at about 19.28° has been attributed to the presence of amorphous carbon and surface defects in carbon nanotubes. The γ band at about 25.81° corresponds to e2g mode of graphite which is related to vibration of sp 2 bonded carbon atoms and the presence of ordered carbon nanotubes in diesel soot. The SEM micrographs provide a clear indication that nanoparticle formed in diesel soot are clusters of carbon nanospheres. Energy dispersive spectrum analysis of diesel soot confirms that the soot particles to be composed of primarily carbon and oxygen along with hydrogen. The camphor soot shows γ and π bands which reveals the presence of crystalline graphitic carbon. The SEM micrographs of camphor show the presence of carbon nanostructures. It is found nanomaterials formed in the diesel soot consists more of disordered carbon, whereas in camphor it is more of ordered graphite like carbon.

“…However, physical mechanism of production and stable configurations of radiation defects and their complexes which can exist in few-layer graphene is not yet well understood . Recently signs of radiation damages were observed even after conventional SEM investigations with electron energies equal to and less than 30 keV [10,11]. It should be noticed that some data correspond ing to radiation effects in monolayer graphene were recently reported [12][13][14][15], however, there is very little volume of information corresponding the experimental investigatio ns of radiation effects in few-laye r graphene [16].…”

A new method that combines inert gas fusion with infrared spectrometric detection for fast simple determination of total oxygen in reduced graphene oxide (RGO) has been established in this paper. The whole analyzing process was introduced, including calibration, temperature selection and sample weight selection. The equation of calculation the oxygen content of RGO in this method was given. The precision of the new method has been verified by measurement of a RGO sample.The RGO after measurement was characterized by X-ray photoelectron spectroscopy (XPS). The relative standard deviation (RSD) of oxygen was 1.02%. The results were consistent with that obtained by the conventional classic method XPS. It has shown that the new method is accurate and efficient. The method of testing a RGO sample needs 140 s. The inert gas fusion-infrared method is a fast simple method.
