In this method, single wall carbon nanotubes are grown by CO disproportionation (decomposition into C and carbon dioxide) at 700-950 in flow of pure CO at a total pressure that typically ranges from 1 to 10 atm. This has provided direct crystallographic evidence for charge order below the Verwey transition, although the magnitude of the estimated charge disproportionation is only 20% of that expected for ideal [Fe. The general mechanism of the radical polymerization of fluorinated monomers includes six elementary reactions (table 1): (1) the initiation by the homolytic cleavage of a molecule with low thermal stability (usually a peroxide); (2) the chain propagation; (3) the chain transfer to monomer; (4) the chain transfer to polymer; (5) the terminal double bond reaction; and (6) the bimolecular termination (through disproportionation or combination) (ref. |
