Home > Press > Iranian, Chinese Scientists Propose New Method for Kinetics Study of Formation of Iron Oxide Nanoparticles

Abstract:
Iranian scientists in association with Chinese researchers studied the kinetics of the formation of iron oxide nanoparticles and developed their correlation by using the results obtained from thermal gravimetric analysis (TGA) and images taken by transmission electron microscope (TEM).

Iranian, Chinese Scientists Propose New Method for Kinetics Study of Formation of Iron Oxide Nanoparticles

Tehran, Iran | Posted on January 13th, 2014

The correlation was calculated based on two parameters time and laboratorial conditions, and it is able to predict and control the size and volume percent of nanoparticles.

Dr. Reza Ahmadi, graduated in materials engineering from Sharif University of Technology, said that the main purpose of the research was to present a method to study the kinetics of the formation and the size of iron oxide nanoparticles during hydrothermal process by using TEM and TGA results, which would be applicable on other nanostructures too.

"Predicting and controlling formation rate and size of nanoparticles and other nanostructures enable us to investigate and control their properties and applications in a more effective manner," he said. "This is very essential."

Results showed that the mean size of particles increased as the reaction time and acidity of the system increased. An interesting characteristic of the ferromagnetic materials observed in this research was their superparamagnetic properties that takes place at very small dimensions (such as 11 nm for Fe3O4) taking into consideration the type of materials. This characteristic is useful in many applications including some medical applications.

Results of the research will help the prediction of the percentage of nanostructured phase formation and the dimensions of nanometric phase, which is consequently useful for the prediction and control of the nanostructure materials properties for its desired application. The researchers are currently investigating the commercialization of the nanoparticles synthesized with various coatings for MRI applications.

Latest results of the research have been published in Ceramics International, vol. 39, issue 5, December 2012, pp. 4999-5005.
