Monodisperse Fe3O4 nanocubes have been successfully synthesized by a facile solvothermal method at 260 ºC in the presence of oleic acid and oleylamine. Well-defined assembly of uniform Fe3O4 nanocubes with average size of 12 nm could be obtained without a size-selection process.

Uniform CoTe and CoTe2 nanotubes have been selectively synthesized via a facile hydrothermal co-reduction route based on the precipitate slow-release controlled process under mild conditions, in which H2TeO3 were employed to supply Te source and sodium hydroxide and aqueous hydrazine was used as alkaline and reducing agent.

Monodisperse Fe3O4 nanoparticles with narrow size distribution could be successfully synthesized in large quantities by a facile solvothermal synthetic method in the presence of oleic acid and oleylamine. The sizes of final products could be readily tuned from 5 to 12 nm by adjusting the experimental parameters such as reaction time, temperature, and surfactants. The magnetic study reveals that the as-synthesized nanoparticles are ferromagnetic at 2 K while they are superparamagnetic at 300 K.

Flower-like NiS microcrystals built of nanoflakes have been synthesized via a hydrothermal process in the presence of l-cysteine, trisodium citrate, and ammonia. l-cysteine was employed as sulfur source and surfactant to regulate the nucleation and growth process.
