Abstract: A method of synthesis of a fulleride of metal nano-cluster is provided. The method is characterized in mechanically alloying metal nano-clusters with fullerene-type clusters. Fullerene molecules in the fulleride of metal nano-cluster are preserved. The alloying is done by milling in a planetary mill. A material including a fulleride of a metal nano-cluster is also provided.

Abstract: A thermoelectric nanocomposite is formed from homogeneous ceramic nanoparticles formed from at least one kind of tellurium compound. The ceramic nanoparticles have an average particle size from about 5 nm to about 30 nm and particularly to about 10 nm. The ceramic nanoparticles are coated with a particle coating in each case. The particle coating is formed from at least one layer of nanostructured, substantially intact carbon material. The nanocomposite may be formed by providing a precursor powder of homogeneous ceramic nanoparticles with at least one kind of a tellurium compound. A precursor coating of nanostructured, substantially intact carbon material is provided for the precursor nanoparticles. Heat treatment of the precursor powder generates the nanocomposite by conversion of the precursor coating into the particle coating.
