TL;DR: In this article, the intrinsic magnetic properties of magnetic nanoparticle colloids are determined by the dipole-dipole interactions and the possible existence of clustering on the colloidal suspension.

TL;DR: The results lead to the possibility of tailoring the ferroic order in multifunctional materials by means of NP size, and suggest that ferromagnetism and ferroelectricity coexist at room temperature in NPs.

TL;DR: In this article, controlled magnetic granular materials with different concentrations of magnetite nanoparticles immersed in a nonconducting polymer matrix were synthesized and, their macroscopic magnetic observables analyzed in order to advance towards a better understanding of the magnetic dipolar interactions and its effects on the obtained magnetic parameters.

TL;DR: In this article, superparamagnetic ferrogels with high swelling ability and potential applications as solvent absorbers and stimuli-responsive drug delivery devices were obtained by a non-toxic and environmentally friendly route based on dispersion of poly(acrylic acid)-coated iron oxide nanoparticles (PAA-coated NPs) in poly(vinyl alcohol) (PVA) solutions followed by freezing-thawing.

TL;DR: In this article, a starch-coated Fe 3 O 4 nanoparticles were synthesized by the precipitation-oxidation of ferrous hydroxide method, and the effect of the polymer on both size and aggregation of the nanoparticles was studied.
