General description

Iron nickel oxide (Fe2O3/NiO) nanopowder is a class of nanomaterial with properties such as superior magnetic, electrical and selective absorption. It can be used as an additive in the formation of membranes for water treatment.

Application

Fe2O3/NiO can be used for applications such as:
  • fabrication of magnetic nanofiber for data storage and transfer
  • electrocatalysts for the splitting of alkaline water
  • formation of composite nanofibers for efficient water oxidation electrocatalysis

Articles

Currently, magnetic nanoparticles (MNPs) are attracting a lot of attention because of the possibility of many novel applications, especially in biomedical research.

Professor Hui Mao explores the use of superparamagnetic iron oxide nanoparticles (INOPs) that offer an alternate contrast-enhancing mechanism.

Professor Yadong Yin (University of California Riverside, USA) examines both direct (thermal decomposition, solvothermal, hydrothermal) and indirect (templated) synthesis methods of magnetite nanocrystals and reviews in detail the landscape of these various synthetic methods for magnetite nanocrystal and their applications in magnetic assembly, magnetic hyperthermia, and Li-Ion batteries.

Magnetic materials permeate numerous daily activities in our lives. They are essential components of a diversity of products including hard drives that reliably store information on our computers, decorative magnets that keep the shopping list attached to the refrigerator door, electric bicycles that speed our commute to work, as well as wind turbines for conversion of wind energy to electrical power.
