Large Scale Synthesis

Large-scale single-crystalline In2O3 nanowires were successfully synthesized by simply evaporating the pure indium at 950ı. The as-synthesized products, characterized by XRD, SEM, and TEM, were pure, structurally uniform, and single crystalline with typical diameters of 10 to 100 nanometers and lengths of up to a few hundreds of micrometers. The growth mechanism of the nanowires also was discussed.

Density-controlled single-crystalline β- SiC nanotubes were successfully synthesized on a large scale by adding Zn into the system via direct thermal evaporation of C 60 onto silicon wafers at 1290°C. Interestingly, no Zn elements can be detected in the final products. However, the addition of Zn power is important because without Zn , density-controlled SiC nanotubes cannot be observed in our experiment. On the basis of the results, a possible growth mechanism was proposed to illustrate the role that Zn played in the growth process. The field emission and hydrophobic performances show strong dependence on the densities of as-synthesized β- SiC nanotubes. The density-controlled β- SiC nanotubes with tunable field emission and hydrophobic properties may have potential in the future of nanotechnology.

Solvent Free Synthesis

We have successfully demonstrated a facile, solvent-free synthesis of highly crystalline and monodisperse Fe3O4 nanocrystallites at ambient temperature avoiding any heating. Solid state reaction of inorganic Fe(II) and Fe(III) salts with NaOH was found to produce highly crystalline Fe3O4 nanoparticles. The reaction, if carried out in the presence of surfactant such as oleic acid–oleylamine adduct, generated monodisperse Fe3O4 nanocrystals extractable directly from the reaction mixture. The extracted nanoparticles were capable of forming self-assembled, two-dimensional and uniform periodic array. The new process utilizes inexpensive and nontoxic starting materials, and does not require a use of high boiling point and toxic solvents, thus is amenable to an environmentally desirable, large-scale synthesis of nanocrystals.
