Oriented assembly of Fe3O4 nanoparticles into monodisperse hollow single-crystal microspheres

Article Abstract:

A convenient and effective 'one-pot' route to high-yield monodisperse hollow single-crystal Fe3O4 Microspheres with tunable diameters in the range of 200-400 nm is developed. Results reveal that Fe3O4 nanocrystals have a strong tendency to self-assemble into large particles in the synthesis process, and dodecylamine (DDA) was the crucial factor that determined the morphologies of the products.

Evolution of single crystalline dendrites from nanoparticles through oriented attachment

Article Abstract:

The single crystalline PbMoO4 dendrites were prepared by a simple hydrothermal method in the presence of surfactants. The formation and evolution of dendrites was investigated by transmission electron microscopy, and the results showed that the dendritic structure was achieved through oriented attachment of nanoparticles along crystallographically specific direction.
