Functionality of Surface-modified Magnetite Nanoparticles …
This chapter is focused on the functionality of surface-modified magnetite (Fe 3 O 4) nanoparticles in magnetorheological (MR) fluids (MRFs).These Fe 3 O 4 nanoparticles are precisely controlled in their particle sizes, particle shapes, surface modifications, and polymer molecular weights. We found that the surface-modified Fe 3 O 4 nanoparticles can form stable …

The Major Magnetosome Proteins MamGFDC Are Not Essential for Magnetite
However, size measurements of 225 magnetosome particles from ΔmamC mutant cells revealed that mature magnetite crystals were on average slightly smaller than those from the wild type (Fig. (Fig.1C; 1C; Table Table2). 2). Complementation of the mutant strain by pAS35 restored the formation of magnetosomes at sizes close to the wild-type range.

Magnetite: Properties and applications – A review
Magnetite (Fe 3 O 4) is a ferrimagnetic mineral, which presents in its crystalline structure iron in two oxidation states, Fe 2+ and Fe 3+.Thus, it is an iron oxide mixed with FeO and Fe 2 O 3 with an inverted cubic spinel structure [1], [2], [3], [4].Magnetite has particular magnetic properties and appears in opaque crystals of black color and brightness varying from metallic to submetallic [5].
