Nanoparticles structures with sizes in the nanometer range, and a spherical or other simple morphology.
This article discusses the properties and applications of nickel iron oxide nanoparticles. Nickel is a Block D, Period 4 element, iron is a Block D, Period 4 element, and oxygen is a Block P, Period 2 element. Nickel iron oxide nanoparticles appear as brown spherical high surface area metal particles. They are graded as toxic.
