Fractal Structures on Fe₃O₄Ferrofluid: A Small-Angle Neutron Scattering Study

Nanoscale Clustering and Magnetic Properties of Mn x Fe3−x O4 Particles Prepared from Natural Magnetite

“…In general, small particles (with radius R 1 ) as primary particles construct larger particles or secondary structures (with radius R 2 ) as clusters with agglomeration and/or aggregation [17]. The cluster formation is affected by the magnetic interparticle interactions between the nanoparticles [18] and the fractal dimension, indicating that a reaction-limited mechanism occurs in the magnetic nanoparticles system [36]. The fractal dimension of Mn x Fe 3−x O 4 tends to be similar to 3, corresponding to the growth of the structures in three dimensions.…”

Preparation of a Magnetic Metal Organic Framework Composite and Its Application for the Detection of Methyl Parathion

“…8 Fe3O4 nanoparticles have attracted much attention for their specific characteristics and have potential applications for ferrofluid, bioprocessing, information storage and separation. [9][10][11][12] Because of its earth-abundant character and high curie temperature, Fe3O4 stands out as a key partner in composites. 13 After Sugimoto's group reported the preparation of magnetite particles with a narrow size distribution in the early 1980s, 14 monodisperse Fe3O4 nanoparticles have been fabricated by various chemistry-based synthetic methods.…”

TEM and Associated Techniques

“…However, observed in this manner, a pattern formed by the suspended iron oxide nanoparticles can be misleading in terms of the actual particle self-organization and the resultant geometries of the particle assemblies, both dependent on the solvent coordination. Moreover, solvent evaporation can contribute to unwanted aggregation of the deposited nanoparticles, further complicating the analysis [97,103,106].…”
