Frequency-Dependent Magnetic Susceptibility of Magnetite and Cobalt Ferrite Nanoparticles Embedded in PAA Hydrogel
TL;DR: Ferrogels holding thermally blocked iron oxide or cobalt ferrite nanoparticles show significant decrease of the magnetic susceptibility resulting from a frozen magnetic structure, confirming that the nanoparticles are unable to rotate thermally inside the hydrogel, in agreement with their irreversible fixation to the polymer network.

Preparation of magnetic polyethylenimine lignin and its adsorption of Pb(II)
Xiaming Zhang,Youming Li,Yi Hou +2 more
TL;DR: Results showed that lignin successfully grafted with polyethyleneimine and coated on the surface of Fe3O4 with a saturation magnetization of 24.08 emu/g, which could achieve good solid-liquid separation, suggesting that Pb (II) adsorption onto sorbents were a chemical process and monolayer adsorptive.

A simple route to diverse noble metal-decorated iron oxide nanoparticles for catalysis.
TL;DR: Using this synthetic route to noble metal-decorated magnetic nanoparticles, Fe3O4@SiO2-M particles show great promise for further development as a precursor to complicated anisotropic materials or for applications ranging from nanocatalysis to biomedical sensing.
Journal ArticleDOI
Preparation of magnetic fluids with particles obtained in microemulsions
TL;DR: In this paper, a mixture of organic solvent, surfactant, and aqueous solution was used for the synthesis of magnetic particles of magnetite, which were stabilized in a carrier liquid, producing a magnetic fluid.

Magnetic Nanoparticles to Recover Cellular Organelles and Study the Time Resolved Nanoparticle‐Cell Interactome throughout Uptake
Filippo Bertoli,Gemma-Louise Davies,Marco P. Monopoli,Mícheál P. Moloney,Yurii K. Gun'ko,Anna Salvati,Kenneth A. Dawson +6 more
TL;DR: Preliminary data on the recovered nanoparticles suggest that significant portion of the original corona is preserved as nanoparticles are trafficked through the cells, analogous to the 'hard corona' that so far has mostly been characterized in extracellular environments.

Magnetic Properties of Stable Dispersions of Subdomain Magnetite Particles
Robert Kaiser,G. Miskolczy +1 more
TL;DR: In this article, stable colloidal dispersions of subdomain-size magnetic particles have been prepared that retain their liquid characteristics in the presence of a magnetic field, correcting for the formation of a nonmagnetic surface mantle one unit cell thick.
