Fabrication of "tadpole" -like magnetite/multiwalled carbon nanotube heterojunctions and their self-assembly under external magnetic field
Article Abstract:
The synthesis of novel "tadpole" -like [Fe.sub.3][O.sub.4]/multiwalled carbon nanotube (MWCNT) heterojunctions were carried out by the position-selectively attaching [Fe.sub.3][O.sub.4] sphere on the tips of (MWCNTs) through a straightforward and effective polyol-medium solvothermal method. The tadpolelike nanocomposites were able to orient and self-assemble into one-dimensional structure under external magnetic field, thus displaying great potential in precise manipulation and organization of carbon nanotube-based structures into integrated functional system.

Reducing reaction of [Fe.sub.3][O.sub.4] in nanoscopic reactors of a-CNTs.
Article Abstract:
Several studies are conducted to understand the reducing reaction of the [Fe.sub.3][O.sub.4] nanowires in various nanoscopic reactors of amorphous C:H nanotubes (a-CNTs), which are then used to analyze the chemical reaction mechanism in such reactors. The results show that the carbon in the a-CNT shell exhibit better reducing properties than hydrogen, which is not the case with a macroscopic system.

Synthesis of polygonized carbon nanotubes utilizing inhomogeneous catalyst activity of nonspherical [Fe.sub.3][O.sub.4] nanoparticles
Article Abstract:
The synthesis of novel carbon nanotubes (CNTs) with polygonal cross sections by heating a powder mixture of ferrocene, oxalic acid and the alkali metal potassium at mediate temperatures is described. The possible growth model is proposed based on the evidence that the formation of polygonized CNTs is determined by inhomogeneous catalytic activity of nonspherical [Fe.sub.3][O.sub.4] nanoparticles.
