Abstract:
Iranian researchers at Ferdowsi University of Mashhad succeeded in the production of super paramagnetic nanocrystals of manganese oxide (Mn3O4) by using very low ultrasonic powers under mild conditions. They did not use any chemical additives for the production of this compound.

Simple Method Yields in Synthesis of Super Paramagnetic Mn3O4

Tehran, Iran | Posted on June 16th, 2012

"In this research, the two methods of ultrasonic radiation (ultrasonic bath) and the classic method of magnetic stirrer for the production of super paramagnetic nanocrystals of Mn3O4 were used," Ms Rohani, one of the researchers of the project," said.

"Results showed that no nanobeam was formed through the classic method, and the mean size of nanoparticles was 2.5 nm."

"However, a combination of nanobeam and nanoparticles was formed in the presence of ultrasonic radiation. In this case, the mean size of nanoparticles was 10 nm, and the nanobeams had a diameter of 12 nm and a length of 100-900 nm. Magnetic measurements showed that the nanocrystal formed by ultrasonic radiation had super paramagnetic properties," she added.

Using an ultrasonic bath as a low-energy source, not using chemical additives, mild temperature conditions, production of nanoparticles in environmental conditions and production of nanobeam in very mild condition in the presence of ultrasonic radiation without using active surfactants, structural formation agents or extreme conditions are among the innovative characteristics of the plan.
