摘要：

A microemulsion-mediated chemical reaction was used to synthesize acicular particles of gamma-Fe2O3 with an equivalent spherical diameter (ESD) of 7-8 nm. From a comparison of the measured values of the hydrodynamic diameter of the water-in-oil microemulsion droplets and the ESD of the resulting gamma-Fe2O3 particles, we show that each microemulsion droplet gives birth to a single particle of gamma-Fe2O3.
