In situ synthesis of platelet graphite nanofibers from thermal decomposition of poly(ethylene glycol)

Article Abstract:

A unique method to produce platelet graphite nanofibers (PGNFs) by in situ thermal decomposition at 750 degree centigrade under nitrogen atmosphere from a mixture containing poly(ethylene glycol) (PEG) serving as the source of carbon and nickel chloride(NiCl2) as catalytic precursor is described. The process proves to be a simple, economical, and safe technique of preparing small uniform diameter high purity, and high degree of graphitization of PGNFs.

Chemical functionalization of magnetic carbon-encapsulated nanoparticles based on acid oxidation

Article Abstract:

Carbon-encapsulated nickel nanoparticles are used as the representative magnetic carbon-encapsulated nanoparticles for chemical functionalization. The results suggested that the magnetic nanoparticles could be well protected, while their magnetic properties could be utilized to guide the transfer of the grafted functional species on the particle surface.
