Synthesis method for well crystallized alloy nanoparticles in aqueous solution under room temperature by controlling the metal complexes condition

Takahashi H., Mabuchi T., Yokoyama S., Tohji K., Tohoku University, JP

In the case of usual nanoparticles synthesis method, the as-prepared metallic nanoparticles often exhibited inhomogeneous compositions and multi-crystalline structures, which does not adequate for the industrial applications. Therefore, in this study, to develop the synthesis [...]

Size-control and Size-selection at the Nanosize Level: Production of CoFe2O4 nanoparticles of unusual high coercivity at room temperature

Chinnasamy C.N., Jeyadevan B., Perales-Perez O., Shinoda K., Tohji K., Kasuya A., University of Puerto Rico, PR

Here, we introduce a solution chemistry technique which involves a `seeding step` under conditions where nucleation and growth rates of particles are controlled to produce single domain well-crystallized CoFe2O4 nanoparticles followed by a size-selective separation [...]
