Examples
- It has many advantages , such as the particles size is well distributed , and its diameter can be well controlled , etc . because of this virtue , reverse micelle shows broad prospects in the preparation of ferrite nanoparticles . hi this work , the syntheses of mnfe2o4 nanoparticles , cofe2o4 nanoparticles and znfe2o4 nanoparticles are prepared by the reverse micelle method , these preparations employed reverse micelles formed with anionic surfactant bis - ( 2 - ethylhexyl ) sodium sulosuccinate ( aot ) , which is considered the most effective surfactant , and another anionic surfactant bis - ( 2 - ethylhexyl ) sodium hydroxy sulosuccinate ( ahot ) , which is a new surfactant , and was synthesized by our own research group . we also synthesized znfe2o4 nanoparticles using the cationic surfactant cetyltrimethylammonium bromide ( ctab )
