Evidence of poly-cyclic aromatic compounds (PAC)
Evidence of poly-cyclic aromatic compounds (PAC)
During a lower temperature production run, crude white crystals were formed in the down-stream end of the furnace tube. Gas Chromatography - Mass Spectrometry determined the crystalline compound was naphthalene.

Example of GO film on quartz
GO films have been produced from natural gas soot and directly from the thermal decomposition of methane and pentane

Primary soot particles are visible through a cracked region of the carbon film, sintering and coalescence are apparent, scale and microscope parameters indicated
TEM micrograph of GO nano structure

Image of apparent changes to surface
Changes to the surface appearance have been observed when the GO film is exposed to 532 nm LASER irradiation, full characterization of any chemical changes is underway
Parts of this work were carried out in the Characterization Facility, University of Minnesota, which receives partial support from NSF through the MRSEC program.
